Initial mass function
(Preview)
An Abundance of Small Stars Stars form from giant clouds of gas and dust in space, as the matter in these clouds comes together under the influence of gravity. A long-standing goal of astronomy has been to determine the population of stars produced in a cloud; that is, how many stars of various sizes fo...

Abell 1763
(Preview)
New observations from NASA's Spitzer Space Telescope suggest that galaxies prefer to raise stars in cosmic suburbia rather than in "big cities." Galaxies across the universe reside in cosmic communities, big and small. Large, densely populated galactic communities are called gala...

Supernova SN1979C
(Preview)
Scientists have found that the type II supernova SN 1979C that exploded in 1979 in the galaxy M100 is as bright today in X-ray light as it was when it was discovered years ago, a surprise finding because such objects usually fade significantly after only a few months.
Using ESA’s XMM-Newton space...

This image shows the effects of a giant black hole that has been flipped around twice, causing its spin axis to point in a different direction from before. The large optical image, from the Sloan Digital Sky Survey, is centered on a radio galaxy named 4C +00.58. The smaller image to the right shows a clo...
