Sunset drama.

I don’t usually get to see sunset terminators because of the mountains and trees to my east so this night was a treat because the moon was at such a high declination that it was overhead. A number of my favorites were in one field of view here. The large crater at the top is Aristoteles (90 km dia.) with Mitchell (31 km) taking a bite out of its southeast (lower right) wall. Due south of this pair is Eudoxus (70 km) and east of that, deep in shadow, is Burg (41 km) in the center of the hexagonal Lacus Mortis. All three of these large craters are recent by lunar standards. The latter two are Copernican age of 1.1 billion years or less while Aristoteles is a older, Eratosthean age between 1.1-3.2 billion years. But if you want something really old, Lacus Mortis, is Pre-Imbrian age may be as much as 4.5 billion years old, that’s 18 rotations of … Continue reading →

Brahe’s crater

The area around Tycho is so busy that you have to study it in pieces. Here we start with Tycho (88km dia.) on left of center fand look to the east (right). One of the first things we run into is below and east of Tycho and the largest named crater in this image, Maginus (168km) an oft overlooked crater lying between the spectacular Tycho and magnificent Clavius (just off the southern edge of this image). Between Tycho and Maginus is the crater Street ( 60km). Then below and to the right of Maginus is a sideways Mickey Mouse formed by three craters. The larger crater in this trio is Deluc (49km). From Tycho going east we see Pictet (65km) almost adjacent and further is Saussure (56km) with and interesting flat bottom. Above this last crater is another large one, Orontius (126km) with a triplet of craters just east of it in order, Huggins (66km), Nasireddin (54km) and above it … Continue reading →

Crater Virus infects Science Week Drawings

Recently here in Ireland we had the phenomena that is Science Week. A nationwide effort by hundreds of people to open the many facets of science to children and adults all over the country.  My offerings were workshops about the Apollo 11 moon landing called Let’s Go To The Moon – Apollo 11, Deadly Moons and Marvellous Mars. All of which I have written about in the past hit the links to check them out. This year a unique crater virus came to visit and spread itself around many drawings. Guidance Increasingly I have being introducing drawing techniques in my workshops.  Sometimes the effect has a slow uptake and other times it has an immediate viral effect. One such action is a tip on crater drawing , kids just love it. Here below we see some drawings that benefited from simple guidence. Examples of the crater virus that invaded hundreds of drawings and created smiles all over the room.   … Continue reading →
