PLANETS FOUND FORMING IN PLEIADES STAR CLUSTER

One of my interests is extrasolar planets (planets beyond our system). This latest news describes possible planet formation around the Pleidies, a pretty little star cluster (that looks like a minuture big dipper) in constellation Taurus. Find the Pliedes with your telescope or binoculars.

Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be
forming or to have recently formed around a star in the Pleiades ("seven
sisters") star cluster, the result of "monster collisions" of planets or

HUBBLE ZOOMS IN ON HEART OF MYSTERIOUS COMET HOLMES

The comet has decreased to 3rd magnitude and supposedly someone said it has lost its color evenwhile it has grown in size (to our Sun). In the sky, this translates to the size of the moon higher in the sky. I will post more of my photos tomorrow. Meanwhile latest news on Hubble spying the comet

HUBBLE ZOOMS IN ON HEART OF MYSTERIOUS COMET HOLMES
---------------------------------------------------
NASA's Hubble Space Telescope has probed the bright core of Comet
17P/Holmes, which, to the delight of sky watchers, mysteriously brightened
by nearly a millionfold in a 24-hour period last month.
