Planets, Priests and a Persistent Myth

The Catholic Church and scientific discovery are utterly incompatible, right? History disagrees.

Last week NASA’s Dawn spacecraft, after a voyage of about eight years, captured incredible video of two bright spots on Ceres. Ceres has an interesting history, labeled for decades a planet, then an asteroid (or minor planet), and most recently a dwarf planet, a category that includes another erstwhile planet, Pluto. Ceres was discovered through the dedication of a Catholic priest, Giuseppe Piazzi (1746-1826), who obtained the best astronomical instruments of his day, and positioned them where they could be used to best effect.

When he was 19, Piazzi joined the Theatine Order of clerics, which supported his doctoral studies in philosophy and mathematics. At 34, he was asked to occupy the chair of higher mathematics in Palermo. Palermo had climatic conditions favorable for astronomical observations, and Piazzi decided to found an observatory there, the southernmost in Europe. He traveled to England to obtain the most accurate telescope then available. With its help he developed a catalog of almost 7,000 stars, the most extensive and accurate up to that time. L’Institut de France awarded it the prize for “best astronomical work published in 1803.” 

Piazzi’s entry into history began on January 1, 1801, when he noticed a faint “star” not contained in any catalog. Tracking it over the following nights, he found that it moved across the background stars the same way planets do. After more than 40 nights, however, it moved too close to the sun to be seen. Would it ever be found again, once it emerged from the sun’s glare? 

That would require the difficult feat of computing its orbit precisely from the positions Piazzi had measured. This was accomplished by the great mathematician Carl Friedrich Gauss, and Piazzi’s object was located again by a German observatory exactly a year after its original discovery. In 1802, Piazzi named it Ceres after the patron goddess of Sicily. 

But what was it? Was it a planet? It moved like one, and didn’t have the characteristics of a comet. The picture was clouded, however, by the finding in short order of three more objects with similar orbits: Pallas (1802), Juno (1804), and Vesta (1807). It turned out that Piazzi had found the first of many thousands of “asteroids” or “minor planets” whose orbits lie mainly in a belt between Mars and Jupiter. Ceres is the largest asteroid, large enough that its gravity squeezes it into a sphere, like a planet and unlike other asteroids. Hence its recent reclassification as a “dwarf planet.” 

Most news accounts don’t mention that Piazzi was a Catholic priest. In fact, the remarkable story of the Catholic clergy’s contributions to science is one of the best-kept secrets of scientific history. The exception is Gregor Mendel; it is widely known that the science of genetics began with the experiments of the Austrian monk. 

But it is the rare person who knows that the big-bang theory, the central pillar of modern cosmology, was the brainchild of the Belgian Catholic priest and physicist Georges Lemaître. In the 1920s, Lemaître showed that Albert Einstein’s equations of gravity allow space itself to expand and, connecting this to observations that distant galaxies were flying apart, he formulated his famous theory of how the universe began. 

The Jesuits have an especially rich scientific tradition. In the 16th century, the Jesuit astronomer Christopher Clavius developed our modern calendar. In the 17th century, Jesuit Giambattista Riccioli mapped the moon, and Christoph Scheiner helped discover sunspots. Francesco Grimaldi discovered the enormously important physics effect called “diffraction,” the effects of which you can see in the colorful bands of a glimmering CD. In the 19th century, the Jesuit Angelo Secchi, a founder of astrophysics, pioneered the study of the sun and stars using the spectra of their light and developed the first spectral classification of stars, the basis of the one now used. 

But Jesuits don’t have all the glory. Blessed Niels Stensen (1638-86) made major contributions to anatomy, especially of the glandular-lymphatic system, and, even more impressively, helped found the science of geology by developing the correct theory of sedimentary rock, geological strata and the origin of fossils, which unlocked Earth’s history. Marin Mersenne (1588-1648), of the Minimite Order, made fundamental discoveries about sound. The work of the Abbé Lazzaro Spallanzani, one of the top biologists of the 18th century, is taught in high-school textbooks today. 

Ask a Catholic audience whose name they associate with the Catholic Church and science. “Galileo!” they shout. Ask them about Lemaître, Grimaldi, Stensen, Secchi—or Piazzi—and you get blank stares. Is it any wonder the science-religion warfare myth persists?

Microwave oven to blame for mystery signal that left astronomers stumped

Australian scientists first detected interference in 1998, which they assumed was from lightning strikes, but earlier this year they finally found the real culprit

Tuesday 5 May 2015 03.21 EDTLast modified on Tuesday 5 May 2015 

The mystery behind radio signals that have baffled scientists at Australia’s most famous radio telescope for 17 years has finally been solved.

The signals’ source? A microwave oven in the kitchen at the Parkes observatory used by staff members to heat up their lunch.

Simon Johnston, head of astrophysics at the CSIRO, the national science agency, said astronomers first detected the signals, called perytons, in 1998. The signals “were reasonably local, say within 5km of the telescope”.

Originally researchers assumed the signals – which appeared only once or twice a year – were coming from the atmosphere, possibly linked to lightning strikes.

Then on 1 January this year they installed a new receiver which monitored interference, and detected strong signals at 2.4 GHz, the signature of a microwave oven.

Immediate testing of the facility microwave oven did not show up with perytons. Until, that is, they opened the oven door before it had finished heating. “If you set it to heat and pull it open to have a look, it generates interference,” Johnston said.

Astronomers generally operate the telescope remotely and do not reside at Parkes. There were, however, a number of operational staff members who maintained the facility and used the microwave oven to heat their coffee or lunch.

Johnston said the “suspicious perytons” were only detected during the daytime and as they now knew, not during the evening when all the staff had finished their shift.


The signals were rare because the interference only occurred when the telescope was pointed in the direction of the microwave oven. And “when you only find a few it’s hard to pin them down”, Johnston said.

The findings have been reported in a scientific paper.

Human interference is a common frustration for astronomers. At the Siding Spring optical observatory in northwest New South Wales, astronomers recently voiced concerns over a proposal for a new coal seam gas project, fearing it could lead to increased light pollution in the area.

Johnston said there were many things that caused interference to the Parkes radio telescope – famous for its role in the moon landing, as portrayed in the movie The Dish – including FM radio, digital televisions, mobile phones and wireless internet. “If we tried to have an observer in Sydney the radio noise would be so terrible you’d never see our astronomy signal,” he said.

Johnston added that in 1967 astronomers at the Haute-Provence observatory discovered what they thought were potassium flare stars. They eventually concluded the spectroscopic observations were probably caused by matches struck in the vicinity.

The telescope was established in Parkes 50 years ago in what was “the middle of nowhere”, Johnston said, far away from any radio noise. But in recent years digital interference from the town was getting worse and worse.

However a new telescope in Western Australia called Australian Square Kilometre Array Pathfinder (ASKAP) was being built in what Johnston called “the quietest site on earth to do astronomy”.

“There’s no mobile phone coverage, no radio station, no Wi-Fi – it’s pristine and quiet and we can look into the universe and see things that you can’t in Parkes.”

Johnston said the new telescope is placed in a protected “radio quiet zone”. “People can’t just go in there with wireless internet or radios – they have to tell us and be properly licensed. This is a big step for us.”

The telescope will be completed in 2016.

This blazing maelstrom is Thor’s Helmet, a cloud of interstellar gas and stellar entrails set alight by a hot, unstable star nearing the end of its days. In this image by astrophotographers Kim Quick and Terry Hancock, the color and structure of this emission nebula hint at its youth and unusual nature.

Thor’s Helmet gets its glow from the massive unstable star WR7, a so-called “Wolf-Rayet” star which ejects much of its gaseous outer layers into space at speeds of up to 2,000 km/s. The ejected material from the star runs into the slower-moving gas floating between the stars. The collision excites the surrounding gas and causes it to emit light.

Wolf-Rayet stars are massive, fast-burning, and short-lived stars on their way to exploding as a supernovae. This phase of the star’s life only lasts briefly, which means Wolf-Rayet stars are quite rare. Only 150 have been discovered in the Milky Way.

The interstellar gas in and around this nebula is chemically enriched by the entrails of the Wolf-Rayet star. The rich blue-green color of the nebula comes from ionized oxygen ejected by the star. The reddish-pink color comes from excited hydrogen gas from the star and in the interstellar medium.

The intricate detail and structure in Thor’s Helmet hints at the history and structure of this short-lived nebula. The bubble-like section may have been blown out during the star’s more sedate life on the main sequence. Additional sections are made from other molecular clouds entwined with the bubble.

Thor’s Helmet, which is more formally cataloged as NGC 2359, lies at a distance of about 12,000 light years and spans about 30 light years.

Red circle marks the location of Thor's Helmet, NGC 2359.

This massive and distant complex is visible in a small telescope in very dark sky, though it’s not an easy object to see. With a 5″ or 6″ scope at low magnification, and a nebula filter, sharp-eyed stargazers can see the brightest sections of Thor’s Helmet about 10º northeast of the Sirius, the brightest star in the sky. Follow a line from the stars ι (iota) Canis Majoris through γ (gamma) Canis Majoris a distance about half again as large as their separation.

The image at top was captured by Kim Quick over 17 nights between 12/28/14 and 2/15/15 from his backyard observatory in Florida under moderately-high light polluted sky conditions using a QSI 583 Mono CCD and Explorer Scientific ED 127 Refractor. It was processed and Calibrated in CCDStack and post-processed in CS3. Total integration time was 27.5 hours.

Making Prototype Mirrors in Wales for the World’s Largest Telescope

Posted by Caroline Gray on Feb 23, 2015 9:28:00 AMGlyndŵr University in Wales is working on a ground breaking scientific project involving the world’s most powerful telescope.

What is the E-ELT or the ESO Extremely Large Telescope?

The E-ELT, the largest ever ground based telescope, is currently being built by the European Southern Observatory (ESO). This is a ground breaking scientific project, it will require, bigger, more accurate, more stable and faster data processing than has ever been achieved.


What makes this telescope different? What will it tell us?

It is bigger, so big it will gather more light than all the existing 8-10m class telescopes on the planet to date….. In simple terms this means improved signal to noise ratio which leads to improved resolution.


The E-ELT telescope is expected to provide answers to some of the most prominent open questions in astrophysics today. Such as…


Are we alone?

Do exoplanets (An exoplanet or extrasolar planet is a planet that does not orbit our Sun and instead orbits a remote star) exhibit living earth like signatures?

The E-ELT will have the resolution to deliver some of the first images of, analyse their atmospheres and deliver important information on the structure of these potential life sources..

The telescope will enable scientists to question some of the fundamental laws of physics…The telescope

Were physical constants really constant throughout the history of the Universe?


What really happened at the big bang?

The telescope offers the opportunity to challenge the very root of our understanding of the Universe since the Big Bang!

The telescope will enable astronomers to challenge, interrogate and develop our understanding of Stars, Galaxies and the Universe as a whole since the beginning of time….

So a truly ground breaking scientific tool has been made possible by the coming together and financing by 16 nations to a budget of €1.1B. This money is intended to be returned to the member states through contract awards for the construction. And this is where Glyndwr University comes in…

One of the challenges (there are many!) when considering the building of the E-ELT telescope is the production of the 39m primary mirror. This mirror will be constructed from 798 hexagonal mirrors. Each mirror will be 1.45m corner to corner and ~50mm thick. Each of these mirrors is required to align with its neighbour to produce an f/0.88 continuous mirror surface with a 39m diameter.

In order to do this the level of accuracy and repeatability of the mirror processing and testing required is unprecedented. Typical industry lead times for optics of this size are of the order of 20 weeks. Therefore to produce this volume of mirrors in the time frame of the telescope build ESO have set the industry a challenge.  Better, faster, cheaper… a common goal of modern manufacturing.

In order to explore the feasibility of serial manufacture on this scale, in 2008 ESO awarded two prototype segment contracts one to an existing large optics supplier (SAGEM in France) and one to an ambitious group of scientists in Wales who had a manufacturing concept that, if proven could deliver the relatively rapid and repeatable polishing process required. This is the project currently active in Glyndwr University’s St Asaph Campus at the Optic Centre.


The team at Glyndwr University have successfully developed a process that can directly polish the hexagonal segments over the full aperture whilst maintaining the edge form. This is an industry first! The team have also produced another world first with their optical test which is certified by ESO to deliver the 2nm RMS test accuracy required.


All of these ground breaking process developments have placed Glyndwr University in a very strong position to play a major role in the delivery of the large quantity of mirrors required for the telescope build. This work will go to tender in the third quarter of 2015 and we are currently working hard to ensure this fantastic manufacturing opportunity is won by the UK and manufacturing stays in Wales



Science Increasingly Makes the Case for God (WSJ Dec 25, 2014)

The odds of life existing on another planet grow ever longer. Intelligent design, anyone?



Dec. 25, 2014 4:56 p.m. ET

In 1966 Time magazine ran a cover story asking: Is God Dead? Many have accepted the cultural narrative that he’s obsolete—that as science progresses, there is less need for a “God” to explain the universe. Yet it turns out that the rumors of God’s death were premature. More amazing is that the relatively recent case for his existence comes from a surprising place—science itself.

Here’s the story: The same year Time featured the now-famous headline, the astronomer Carl Sagan announced that there were two important criteria for a planet to support life: The right kind of star, and a planet the right distance from that star. Given the roughly octillion—1 followed by 24 zeros—planets in the universe, there should have been about septillion—1 followed by 21 zeros—planets capable of supporting life.

With such spectacular odds, the Search for Extraterrestrial Intelligence, a large, expensive collection of private and publicly funded projects launched in the 1960s, was sure to turn up something soon. Scientists listened with a vast radio telescopic network for signals that resembled coded intelligence and were not merely random. But as years passed, the silence from the rest of the universe was deafening. Congress defunded SETI in 1993, but the search continues with private funds. As of 2014, researches have discovered precisely bubkis—0 followed by nothing.

What happened? As our knowledge of the universe increased, it became clear that there were far more factors necessary for life than Sagan supposed. His two parameters grew to 10 and then 20 and then 50, and so the number of potentially life-supporting planets decreased accordingly. The number dropped to a few thousand planets and kept on plummeting.

Even SETI proponents acknowledged the problem. Peter Schenkel wrote in a 2006 piece for Skeptical Inquirer magazine: “In light of new findings and insights, it seems appropriate to put excessive euphoria to rest . . . . We should quietly admit that the early estimates . . . may no longer be tenable.”

As factors continued to be discovered, the number of possible planets hit zero, and kept going. In other words, the odds turned against any planet in the universe supporting life, including this one. Probability said that even we shouldn’t be here.

Today there are more than 200 known parameters necessary for a planet to support life—every single one of which must be perfectly met, or the whole thing falls apart. Without a massive planet like Jupiter nearby, whose gravity will draw away asteroids, a thousand times as many would hit Earth’s surface. The odds against life in the universe are simply astonishing.

Yet here we are, not only existing, but talking about existing. What can account for it? Can every one of those many parameters have been perfect by accident? At what point is it fair to admit that science suggests that we cannot be the result of random forces? Doesn’t assuming that an intelligence created these perfect conditions require far less faith than believing that a life-sustaining Earth just happened to beat the inconceivable odds to come into being?

There’s more. The fine-tuning necessary for life to exist on a planet is nothing compared with the fine-tuning required for the universe to exist at all. For example, astrophysicists now know that the values of the four fundamental forces—gravity, the electromagnetic force, and the “strong” and “weak” nuclear forces—were determined less than one millionth of a second after the big bang. Alter any one value and the universe could not exist. For instance, if the ratio between the nuclear strong force and the electromagnetic force had been off by the tiniest fraction of the tiniest fraction—by even one part in 100,000,000,000,000,000—then no stars could have ever formed at all. Feel free to gulp.

Multiply that single parameter by all the other necessary conditions, and the odds against the universe existing are so heart-stoppingly astronomical that the notion that it all “just happened” defies common sense. It would be like tossing a coin and having it come up heads 10 quintillion times in a row. Really?

Fred Hoyle, the astronomer who coined the term “big bang,” said that his atheism was “greatly shaken” at these developments. He later wrote that “a common-sense interpretation of the facts suggests that a super-intellect has monkeyed with the physics, as well as with chemistry and biology . . . . The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question.”

Theoretical physicist Paul Davies has said that “the appearance of design is overwhelming” and Oxford professor Dr. John Lennox has said “the more we get to know about our universe, the more the hypothesis that there is a Creator . . . gains in credibility as the best explanation of why we are here.”

The greatest miracle of all time, without any close seconds, is the universe. It is the miracle of all miracles, one that ineluctably points with the combined brightness of every star to something—or Someone—beyond itself.

Sayın Hocam,

Filmi izledim, başarılı bir film;
Amacı itibariyle İnsanoğlu Gezegeninin eninde sonunda zamanını dolduracağına ve yıldızlararasına açılmamızı konu almakta,
Film belgesel tadında değil (olmaması da gerekli),
Yıldızlararası seyahate için biyolojik saat ile oynama fikri mantıklı,
Seyahat esnasında kullanılan yakıta bir gönderme yapılmamış (Bu sorunu solucan deliği ile çözülmüş) bu açıdan ?
Solucan deliğinden geçme fikri hala teoride var (ancak sağlam olmayan bir teori), solucan deliklerinin uzay-zaman boyutunda daha kestirme koordinat ekseni ile yolculuk etme fikri var, ancak bunun fiziksel olarak nasıl gerçekleşeceğine dair bir öngörü tam anlamıyla yok (henüz yok).
Varsayalım solucan deliğinden etkilenmeden geçtik başka bir yıldız sistemine ulaştık ve filmde konu olduğu gibi sistemde bir de karadelik var!
Karadelik aslında bir kütleçekim alanı olarak kendisini sergiler, Bizim yıldızımızın hacmini ışığın bile kurtulamayacağı “kurtulma yarıçapına” sıkıştırırsak olur bize karadelik.
Tüm gezegenler yine aynı yörüngede dönmeye devam eder (Işıma basıncının oluşturduğu itici etki, karadeliğin durmadan kütlesinin artması hesap dışında bırakılırsa…)
Ancak bir karadeliğin içerisine girmek mevcut fizik bilgimiz ile hayal,
Bunun ana nedeni karadeliğe yaklaştıkça (Güneşe göre üstel oranda dik bir yokuştan aşağı inmek gibi…) kütle çekimi muazzam artar. Şuan elimizdeki bilgiler bunu net olarak kanıtlamakta (Özellikle Chandra Uzay Teleskopundan gelen X-ışını bilgileri…)
Karadeliğe yolculuğumuz başladığı anda uzay gemisinin ön tarafı ile arka tarafı (karadelik yönündeki her bir atomik derinlik diyebiliriz) farklı gravitasyonel (kütle çekimsel)  farka maruz kalır, Karadeliğe yaklaştıkça gemi maruz kaldığı bu iç ivmeden dolayı parçalanır ve karadeliğin olay uykuna (ışığın bile kaçamayacağı çap) gelmeden önce atomik parçalara bölünür. Atomik parçalara bölündüğünde gravitasyonel etkileşim düşeceğinden dolayı (hala mevcut ve karadeliğin toplam kütlesi ile de ilişkili) bu formda yutulur. Yutulma öncesi tıpkı otobanda giderken 5 şeritli yolun 1 şeride düşmesinden kaynaklı atom-atom etkileşimleri meydana gelir, bu da X-ışını olarak karadelik olay ufku üstünde enerji salınımına neden olur. Bu ışınım Karadeliklerin imzası olarak tanımlanır. Chandra Uzay teleskopu temel olarak bu X-ışınlarının konumlarından olası karadelikleri belirlemekte;

Kısacası karadeliğin içine dalmak iyi bir fikir değil. Peki oldu oldu içine daldık (postüla), içerisindeki maddenin bilenen madde olmadığını düşünebiliriz, Buradaki fiziksel sorun zamanın olmaması!
Zaman tanımı olmadığı için maddeyi grupladığımız fermiyon, bozon gibi sınıflandırmaları yapmak güç hale gelmekte (bozon olma ihtimali daha yatkın gelir, bozonlar aynı enerji durumunda bulunan parçacıklardır, ışık gibi…)
Karadelikler Stephen Hawking’in de ele aldığı gibi Enformasyon teorisi ile de incelenmekte (Karadeliğe giren bilgi ne olur,…).
Filmde ele alınan Kütle çekim dalgası ile haberleşme olabilir ancak bu kadar nokta atışı olması ve zamanda geriye doğru hareket etmesi ?
Kütle ve kütle çekimi zamana bağlı bileşenler ve zamanda geriye doğru hareket doğrudan ışık hızı ile ilişkili (Işığın hızına bir kütlenin ulaşması şuan ki bilgimiz ile imkansız, (Hesaplamalarda imajiner-sanal sayı yani karekök içerisinde “-” ifade çıkmasından dolayı gerçek uzayda yok…)
Lorentz dönüşüm formülü ele alındığında ışığın hızına ne kadar yaklaşırsak üstel oranda enerji harcamak zorundayız ayrıca bu toplam kütlemizle de orantılı! Bu da ışığın hızına erişemeyeceğimiz bir kütleyi tanımlamakta.
Filmde bir de gezegen indiklerinde 1 saat içerinde geçen yıllar!?
Bunun mümkün olabilmesi için gezegenin kütle çekiminin muazzam olması lazım!
Geminin dayanımı olduğunu varsaysak bile gezegenin üzerine inmeden yörüngedeyken canlı yaşamı son bulur.
Ayrıca Atmosferinin çok ince olacağını (Aslında o büyüklükteki bir gezegenin bir gaz devi, bir yıldız olacağını) söylemek daha mantıklı…
Ayrıca bu büyüklükte zaman farkını oluşturan bir gezegen kütlesinden o kadar küçük bir gemi ile havalanmak mümkün değil (Karşıt madde kullanmıyorsa…)
İkizler paradoksunu anlatmak için iyi bir metot gerçi…
İniş yaptıkları gezegendeki dalgaların yüksekliği ile hızı da ayrı bir sorun,
500 metreden daha büyük bir dalganın hareket hızının saatte 500km/saat olmayacağı kesin,
Sonuç olarak, Güzel başarılı bir film, dediklerimiz olsaydı belgesel olurdu :) O yüzden Bilimi sevdirmek için ve hayal gücü için oldukça yararlı izlenesi bir film.
Benim gezegenler arası seyahat fikrim (tamamı benim düşüncem değil tabi ki), İnsan gibi büyük kütlelerin değil DNA gibi temel bilgilerin transferi…
Filmde embriyo şekilnde ele alınmış ancak o bile uzay seyahatlerinde korunmayabilir. Onun yerine bir virüs ile birleştirilmiş ve canlıların DNA’larına eklenebilen bir veri transferi daha mantılı gibi ( Gerçi ortaya çıkan şey  insan olmayacak Şey+İnsan…) Bu da ilkel bir fikir antreman yapmak lazım… :)
Saygı ve Sevgilerimle.
