A star is slowly snuffing the life out of an alien planet. But in a macabre twist, material stripped out of the dying worlds atmosphere has become a death shroud enveloping the gas giant and its star.

Doomed White Dwarf Stars to Spawn Supernova in Colossal Crash - A pair of newly discovered white dwarf stars that are rapidly orbiting each other are on their way to a catastrophic collision and a supernova explosion, astronomers say.

Pulsars are the dead cores of massive stars rotating on their axes, often hundreds of times per second. The pulsar's magnetic poles emit radio and optical radiation beams that flash across our line of sight, making the star appear to blink on and off.

What's a double pulsar?

Pulsars are the dead cores of massive stars rotating on their axes, often hundreds of times per second. The pulsar's magnetic poles emit radio and optical radiation beams that flash across our line of sight, making the star appear to blink on and off.

Astronomers at NASA have stumbled upon what appears to be the most luminous pulsar ever discovered, but they almost mistook it for a black hole. After measuring the dead star's output, they found it was outputting as much energy as 10 million suns -- shockingly powerful, considering how much smaller it is than our own star

Two extremely bright stars illuminate a greenish mist in this and other images from the new GLIMPSE360 survey. This fog is comprised of hydrogen and carbon compounds called polycyclic aromatic hydrocarbons (PAHs), which are found right here on Earth in sooty vehicle exhaust and on charred grills. In space, PAHs form in the dark clouds that give rise to stars. These molecules provide astronomers a way to visualize the peripheries of gas clouds and study their structures in great

M2-9 "Minkowski's Butterfly  "this nebula has a kind of lighthouse thing going on with the two beams of light which appear blue in my image...yes, they rotate something like a lighthouse) and used it to generate some colors for the nebula. This resulted in SII for the red channel, STIS / MIRVIS data in the green channel, and OIII in the blue."

"Earth-like Planets More Widespread in Universe than Previously Believed"    The NASA artist's concept at top of the page shows a faraway solar system like our own -- except for one big difference. Planets and asteroids circle around not one, but two suns. NASA's Spitzer Space Telescope found evidence that such solar systems might be common in the universe.
