... Calendar . ... I n the last day of the International Year of Astronomy ( early evening of 31 December 2009), the Moon had the smallest partial eclipse that we have seen in Ireland and the UK for 40 years: the Moon was 8% covered by the Earth's shadow. Incidentally, this was also a "Blue Moon" - the name given for the second full Moon within a calendar month. ... International Year of Astronomy, Ireland National Node . ...

Astronomy Picture of the Day . Cheering a Total Solar Eclipse . ... That's what many exuberant sky watchers did across Indonesia during a total eclipse of the Sun last week. There and then, the land and sky went dark during the day as our Sun disappeared for a few minutes behind our Moon. ... At the same time, in the opposite direction, NASA 's EPIC camera aboard NOAA 's DSCOVR satellite captured the shadow of the Moon moving across the Earth. ...

That's what many exuberant sky watchers did across Indonesia during a total eclipse of the Sun last week. ... The total eclipse was only visible from a narrow swath of Earth that included several Indonesian islands. At the same time, in the opposite direction, NASA 's EPIC camera aboard NOAA 's DSCOVR satellite captured the shadow of the Moon moving across the Earth. ...

... HUBBLE UNCOVERS DUST DISK AROUND A MASSIVE BLACK HOLE . Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052. ... Because the jets in NGC 7052 are not perpendicular to the disk, it may indicate that the black hole and the dust disk in NGC 7052 do not have a common origin. ... NGC 7052 is located in the constellation of Vulpecula, 191 million light-years from Earth. ...

The eclipse lightcurve was computed on a grid of 505 time steps separated by approximately 1.3 days, for a range of values of the disk scale height, , the inclination, i , and central hole radius, . The opacity parameter, approximately equal to the ``vertical'' optical depth of the disk, is: . ...

... 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. ...

... Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052. ... Because the front end of the disk eclipses more stars than the back, it appears darker. ... Despite its size, the disk is 100 times less massive than the black hole. ... The bright spot in the center of the disk is the combined light of stars that have crowded around the black hole due to its strong gravitational pull. ...
