... This colorful telescopic view towards the northern constellation Lyra reveals dim outer regions around M57, popularly known as the Ring Nebula. While modern astronomers still refer to M57 as a planetary nebula, at one light-year across M57 is not a planet but the gaseous shroud of a dying sun-like star. ... Mercury Transits the Sun . ... The outer gasses of the star expelled into space appear from our vantage point as if we are looking down a helix. International Space Station in Transit . ...

... The apparent path of the Sun across the sky. ... Like the planets, the Sun, too, moves around the zodiac, making one complete circuit each year. ... In one year, as the Earth completes a full circuit around the Sun (drawing above), the Earth-Sun line and its continuation past Earth sweep the entire plane. ... Since the Sun and Earth are in the plane of the ecliptic, the line is automatically in that plane too; if the moon is also on the same line, it must be in the plane of the ecliptic as well. ...

... Like the night sky on the Earth, the martian sky hosts a plethora of astronomical phenomena occurring around the clock in a neverending space opera played out for the benefit of robotic and future human observers alike. ... Moons . Mars has two moons, Phobos and Deimos . ... Under the same conditions, Deimos would be as bright as -5, somewhat brighter than the planet Venus appears in Earth's sky. ... The moons are also eclipsed by Mars itself (a situation analogous to lunar eclipses at the Earth). ...

... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

... For a long time we've known that planets form and live around stars. ... When a star is born, any leftover gas and dust forms a disc around it, similar to Saturn's rings. Within this disc, small dust grains made of rock sometimes form. ... Now, for the first time ever astronomers have spotted solid grains in the gassy disc around a 'brown dwarf' an object that is neither a planet nor a star. ... Astronomers didn't expect to find these solid grains around brown dwarfs for a number of reasons. ...

... Bad Astronomy . ... This first Snack of the year 2000 (yes, I am one of those who says the Millennium begins in 2001) will talk a little about a wonderful event: a total lunar eclipse. On the evening of Thursday, January 20 (or the early morning Friday, January 21 if you lives east of England) the Moon will go undergo one of the best eclipses it can. ...

During an eclipse, Sun, Earth and Moon form a straight line, and therefore the center of the Earth's shadow is at the point on the celestial sphere which is exactly opposite that of the Sun. ...
