Hi everybody

Here is the latest article from the Astronomy site at

Are There Solar Eclipses on the Moon?
Total solar eclipse: the Sun a black circle framed by an ethereal corona. Dark enough to see stars, and for birds to go to sleep – yet an eerie darkness unlike night. The Sun can also be eclipsed on other Solar System planets as long as they have moons. But what would we see from our own Moon?

*Solar eclipse coming in a few days*
A reminder that there's a lot of useful information, links, and interesting things about solar eclipses on this forum thread:

*Discoveries and Space missions*

(1) August 10, 1990: NASA's Magellan spacecraft entered orbit around Venus to begin radar mapping of the surface.
(2) August 12, 1877: Asaph Hall discovered the Martian moon Deimos.
(3) August 12, 2005: Mars Reconnaissance Orbiter (MRO) was launched. It's still carrying out
reconnaissance and exploration of Mars from orbit.
(4) August 17, 1970: Soviet probe Venera 7 was launched. When it landed on the Venusian surface, it became the first spacecraft to land on another planet and first to transmit data from there back to Earth.
(5) August 18, 1868: Observations made at a total solar eclipse led to the discovery of the element helium.
(6) August 18, 1877: Asaph Hall discovered the Martian moon Phobos.
(7) August 19, 1982: Svetlana Savitskaya traveled into space on Soyuz T-7, becoming the second woman in space, 19 years after the historic flight of Valentina Tereshkova.


(1) August 8, 1948: Svetlana Savitskaya, second woman in space and first to perform a spacewalk.
(2) August 19, 1646: John Flamsteed, the first Astronomer Royal at Greenwich Observatory, compiler of an important celestial atlas.
(3) August 19, 1891: Milton Humason, American astronomer whose careful measurement of the radial velocities of several hundred galaxies underpinned the work of Edwin Hubble.
