Who Named That Crater?
11.05.2004 | Лунное фото дня
Lunar nomenclature, which is in some ways the least important aspect of the Moon, has a fascinating history. It doesn't really matter what a feature is named as long as everyone uses the same name for it.
Galileo's Colorful Moon
10.05.2004 | Лунное фото дня
The Moon is a mono-color sphere - shades of grey, chromatically bounded by some whitish glare and black shadows. The problem is that our eyes, so wonderfully sensitive to faint light and subtle hues aren't good enough.
The Crater Formerly Known As Prinz

Well, it actually still is known as Prinz. I can't say much about the crater itself - its a 47 km wide crater with a completely mare-flooded interior. The north rim of the crater rises a kilometer above the mare surface, but most of the southern rim is gone. Where did it go?
Chandrayaan-1

With the excitement of the US's plan to return to the Moon it is easy to overlook the fact that American satellites won't be the only ones there. Indeed, there may be other humans on the Moon by the time American astronauts return.
Deslandres South
7.05.2004 | Лунное фото дня
Deslandres - previously informally called Hellplain - is a fascinating, but often overlooked feature. With a diameter of 234 km (slightly bigger than Clavius at 225 km), Deslandres is one of the larger craters on the nearside. This low Sun image by Italian amateur Cristian Fattinnanza well shows some perplexing features.
Heavenly Hevelius
6.05.2004 | Лунное фото дня
Bruno Daversin has done it again! This recent image of Hevelius is the finest ever taken from the surface of the Earth! Ignomiously stuck near his lunar rivals Riccioli and Grimaldi - they ignored all the names he had given to craters - Hevelius is an 106 km wide crater that once probably looked like Copernicus.
Magnificent Greek Eclipse!
5.05.2004 | Лунное фото дня
Across many parts of Europe clouds and rain blocked the lunar eclipse last evening. But in Athens, Greece, the clouds cleared 45 minutes before first contact and Anthony Ayiomamitis clicked away every five minutes, documenting the changing hue of the Moon as it orbited through Earth's shadow.
Inside Nectaris

Mare Nectaris is one of the smallest mare on the floor of an impact basin. This low sun mosaic by Peter Berry provides a close-up view of relations between the mare lavas and adjacent impact craters.
Bully for Bullialdus!
3.05.2004 | Лунное фото дня
Here are two good images of Bullialdus - which is best? Its pretty clear that the resolution of the right image - taken with the 24" Ludiver telescope is excellent - perhaps 800 meters! Small craters are cleanly visible on the floor and outer ramparts - these could be counted to estimate Bullialdus' age in billions of years.
Lunar Eclipse Preview
2.05.2004 | Лунное фото дня
On Tuesday, May 4 observers from Europe to India, including Africa, have a chance to observe a lunar eclipse. For observers who want to do "serious work" during the eclipse there is actually little to learn about the Moon, but the eclipse is a great probe of Earth's atmosphere.
