Go Observe Copernicus

Sacred Space Astronomy avatarPosted on February 28, 2020 by Deirdre KelleghanFebruary 28, 2020

  Nicolaus Copernicus was born in the city Torun, Poland in 1473.  After many decades of observation and study he came to write a book called ” On the Revolutions of Heavenly Spheres “. It was published in 1543 shortly after his death. This book was pivotal in the acceptance that the sun is in the centre of our solar system orbited by the planets. Copernicus made many contributions to astronomy, therefore a crater of massive proportions was named for him on the moons surface. Copernicus Crater June 2nd 2009 From memory I was tired when I started this drawing, it has been a busy day. Because I ended the session early I therefore  considered the drawing unfinished. However, looking back on it some details are worth noting. From my point of view, if I do not finish the sketch at the eyepiece it never gets finished at all. Someone suggested to me that I could finish it using photographic … Continue reading →

Agassiz’s mentor

Sacred Space Astronomy avatarPosted on November 5, 2019 by Richard HillNovember 5, 2019
This entry is part 12 of 38 in the series Lunarcy

When the libration is right you get a rare view of a huge crater that is normally out of sight. Here you can see it as a large oval near the limb with black basaltic flooded areas on its floor and a sparkling white offset central peak. This is the great crater Humbolt (213km dia.) named after the explorer, naturalist and geographer that was the mentor of Louis Agassiz. This presentation gives us a nice demonstration of just how shallow these grand depressions are. It has huge cliffs on the far side and a floor covered with rimae just barely seen from earth view here. These were likely caused from settling of the flooded floor as it cooled. Adjacent to the near side of Humbolt is the ghostly outline the crater Phillips (128km). Just beyond Phillips is a small bright floored crater Phillips A (13km). In the upper left corner of this image is the fabulous crater Petavius with the … Continue reading →

Plateau Sunrise

Sacred Space Astronomy avatarPosted on September 17, 2019 by Richard HillSeptember 17, 2019  
This entry is part 8 of 38 in the series Lunarcy

Sunrise on the Aristarchus Plateau is always a thrilling sight whether in your first 60mm telescope or a 400mm cannon! The eye-popping crater Aristarchus (41km diameter) in the center of this image, is the brightest crater on the moon and at 175 million years old, a Jurassic Crater, it’s one of the younger ones. Some dinosaur had a front seat to a spectacular impact show! Notice the nice terracing on the interior wall of this crater. Most of the Plateau is in shadow here. Aristarchus itself is in the southeast corner. You can see the east side of the Plateau going north from Aristarchus. Above and to the right of Aristarchus is the arc of the partially flooded Prinz (49km) and the beautiful Rimae Prinz just above. Immediately above the north rim of Prinz is the odd crater Vera. It is the south end of one of the rimae that you can see running north a little further to the … Continue reading →

In the Sky This Week – August 14, 2018

Sacred Space Astronomy avatarPosted on August 14, 2018 by Bob TrembleyAugust 14, 2018
This entry is part 57 of 179 in the series In the Sky This Week

The constellation Orion is now fully visible in the eastern predawn sky; I had someone at a Perseid meteor party ask me if Orion was what they were seeing in the east – I laughed and mentioned my post from last week where Orion had not quite fully risen before sunrise. The southern sky will be simply fantastic for observing this week, with 3 three planets splashed across the sky. The Moon joins the planets in the south later this week; this weekend will be an outstanding time to do some sidewalk astronomy – which is exactly what my wife and I will be doing at the Michigan ComicCon this weekend at Detroit’s Cobo Center! The Moon joins Venus and Jupiter in the western sky at dusk on Aug. 14th. Southern Hemisphere: From Antonina, Brazil, Venus and the crescent Moon are high in the western sky after sunset on Aug. 14th. The Moon The Moon is a waxing crescent visible … Continue reading →

Eratosthenes Drawing Drama plus an Experiment opportunity for schools all over the planet

Sacred Space Astronomy avatarPosted on March 17, 2017 by Deirdre KelleghanMarch 17, 2017

On that cold evening back in 2007 Eratosthenes looked powerful in its position emerging into the suns warm rays. Rupes Recta was also inviting and Plato almost called me again. Even drenched in sunlight Plato’s steel grey floor carried those unmistakable flame shaped shadows. Eratosthenes is a truly dramatic crater, a sweeping mountain chain whips away from it in a visual series, of broken, deep shadows. Montes Appeninus is cut and chopped first by Mons Wolf, and then by Mons Ampere. Next in line, Christian Huygens name is lent to Mons Huygens named in honour of the discoverer of Saturn’s largest moon Titan . This high mountain (164,000ft) is a billion miles away from those primal methane or ethane seas discovered by the Cassini Huygens mission on one of its routine flybys. Mons Bradley and Mons Hadley cradle the Apollo 15 lunar landing area from 1971. A mission that put wheels on the moon for the first time. This wonderfully … Continue reading →

Carbon hexagonal cycles are at the basis of polycyclic aromatic hydrocarbons, a class of molecules that compose the cold interstellar medium. So hexagons are pretty much everywhere in the Universe!

  • Christopher M. Graney January 4, 2021 at 10:43 am on Carols versus Matthew on the Star of WonderI should have been more clear. When I said "This sounds just like the Great Conjunction of 2020", I meant it sounds like that *kind* of thing -- something no one who was not an astronomer would have noticed it just by chance.
  • Alfred Kracher January 2, 2021 at 10:47 am on Carols versus Matthew on the Star of WonderEmbellishments of Matthew’s simple “star” into a spectacular miracle are all but irrresistible. Already in the apocryphal 2nd century Gospel of James it shines with an “incredible brilliance amidst the constellations and making them seem dim.” And over the centuries artists of all kinds have further expanded on these exaggerations,...
  • Fr. Timothy Sauppé January 2, 2021 at 5:30 am on Carols versus Matthew on the Star of WonderI thought the biggest objection to the Jupiter/Saturn conjunction being the “Star of Bethlehem” was the 800 year cycle of its occurrence viz. the timing is off. Also, I am reminded of a comment of an amateur astronomer when he went to Chile, up in the Andes. He said there...
