NASA's Spitzer Space Telescope has set its infrared sight on a major galactic collision and witnessed not death, but a teeming nest of life. The colliding galaxies, called the Antennae galaxies, are in the process of merging together.

Three powerful blasts from three wholly different regions in space have left scientists scrambling. The blasts, which lasted only a few seconds, might be early alert systems for star explosions called supernovae, which could start appearing any day now.

LOS ANGELES - It may take much longer than scientists have thought for violent turbulence to turn grains of space dust into new planets.    A NASA telescope recently discovered evidence that the most violent part of the process in forming an Earth-sized planet - the collisions between colossal chunks of rock - may last hundreds of millions of years instead of 10 million years, scientists said Monday at NASA's Jet Propulsion Laboratory in Pasadena, Calif...

This is the third article in a series of four articles each with a separate explanation of different quantum phenomena. Each article is a piece of a mosaic, so every one is needed to understand the final explanation of the quantum astronomy experiment we propose, possibly using the Allen Telescope Array and the narrow-band radio-wave detectors being build by the SETI Institute and the University of California, Berkeley.

Those who are involved in popularizing astronomy are asked certain questions time and again.&nbsp; One of these is 'How many stars are there?' Only when one is blessed with a rare glimpse of a star-spangled sky with its myriad luminaries, can we understand why this question occurs.&nbsp; Special computer analysis can readily answer the question.&nbsp;

A bunch of rowdy comets are colliding and kicking up dust around a dead star, according to new observations from NASA's Spitzer Space Telescope. The dead star lies at the center of the much-photographed Helix nebula, a shimmering cloud of gas with an eerie resemblance to a giant eye.
