This Supernova Could Change Everything We Know About How Stars Explode
This is the aftermath of an exploding star (G299, by name) and it's undoubtedly beautiful. But what it also is is very, very strange — and it just might turn all that we know about how stars explode on its head. Why is it so uneven?
October 23, 2007 The aftermath of the death of a massive star is shown in beautiful detail in this composite image of G292.0+1.8. In color is the Chandra X-ray Observatory image - easily the deepest X-ray image ever obtained of this supernova remnant - and in white is optical data from the Digitized Sky Survey. Although considered a "textbook" case of a supernova remnant, the intricate structure shown here reveals a few surprises.
Researchers studying what appears to be a beefed-up version of our solar system have discovered that it is encased in a halo of fine dust. The findings are based on infrared data from NASA's Spitzer Space Telescope and the European Space Agency's Herschel Space Observatory, in which NASA is a partner.
Algunas de las vistas más impresionantes del Universo son creadas por las nebulosas, nubes de gas caliente y brillantes.

Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away.
This photo from NASA's Hubble Space Telescope shows an ominous pillar of gas and dust known as the Cone Nebula. The image shows the top portion of the nebula that is 2.5 light years in height. The Cone Nebula is 2,500 light-years from Earth in the Monoceros constellation. The red halo of light seen around the pillar is caused when ultraviolet radiation causes hydrogen gas in the nebula to glow.
A perfect 10 for the Hubble Space Telescope! This once-in-a-lifetime image shows a pair of gravitationally interacting galaxies called Arp 147. The galaxy on the left, or the "one", is relatively undisturbed, whereas the galaxy on the right, or the "zero", is a messy ring of intense star formation. Image credit: NASA, ESA and M. Livio (STScI)
