Dr Brian Geoffrey Marsden passed away Thursday, Nov 18 at the age of 73 following a prolonged illness.

Swiss astronomer Jose De Queiroz on Wednesday announced the discovery of two new asteroids between the orbits of Mars and Jupiter.

A tiny asteroid discovered just hours ago at an Arizona observatory will enter Earth's atmosphere harmlessly at approximately 10:46 p.m. Eastern time tonight (2:46 a.m. Greenwich Mean Time). There is no danger to people or property since the asteroid will not reach the ground.

A once-faint comet has made a sudden leap from obscurity to center stage. Comet 17P Holmes, now visible to northern hemisphere residents, increased its brightness by a factor of one million this week, going from magnitude 17 to 2.

WASHINGTON -- Astronomer David Tholen spotted it last year in the early evening of June 19, using the University of Arizona's Bok telescope. It was a new "near-Earth object," a fugitive asteroid wandering through space to pass close to Earth.
