In an article in the International Journal of Astrobiology, P. McCafferty discusses the possibility of a red, blood-like life form living inside meteors. This conclusion raises the possibility that…

At 1014 gauss, atoms are compressed into tiny needles whose widths are only 1% of their lengths. X-ray photons readily undergo an exotic process where they change into matter and anti-matter…

The unique planetary nebula NGC 2818 is nested inside the open star cluster NGC 2818A. Both the cluster and the nebula reside 10,400 light-years (3.2 kiloparsecs) away, in the southern constellation…

What is life is a valid question to some because they would simply like to make some.  Yet others, although they don't know what it is, search for life in …

Researchers have discovered that the mysterious overweight stars known as blue stragglers are the result of 'stellar cannibalism', where plasma is gradually pulled from one star to another to form a…

XMM-Newton has caught the fading glow of a tiny celestial object, revealing its rotation rate for the first time. The new information confirms this particular object as one of an extremely rare class…

Many objects in the universe emit radio waves. In 1931, American physicist Karl Jansky first detected radio static from our own Milky Way galaxy. Similar emission from other galaxies creates a…

Astronomers say they may have solved one of those classic chicken-and-egg problems, namely, which came first in the early Universe, galaxies or the supermassive black holes seen at their cores. Chris…

NASA's Fermi Gamma-ray Space Telescope has discovered 12 new gamma-ray-only pulsars and has detected gamma-ray pulses from 18 others. The finds are transforming our understanding of how these stellar…

Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of…
