NASA scientists using the Chandra X-ray Observatory have made a new discovery showing that the Milky Way's outer spiral arms extend significantly farther than previously mapped. The findings, published on July 8, suggest astronomers may need to revise current models of our galaxy's structure…
WASHINGTON — Unlike our sun, most of the largest stars in the cosmos are not solo acts, but rather are born together with another star in what is called a binary system, destined to spend their lives gravitationally bound in a cosmic marriage. But not even the best marriage — on Earth or in space — lasts forever.
This multiwavelength scene shows the Jellyfish Nebula supernova remnant (right), the interstellar cloud it is interacting with, and a distinctive curving filament to its upper left. The filament, which is shown here both in optical and ultraviolet light, is the visible part of an overlapping supernova remnant, G189.6+3.3, that is more prominent in radio and X-rays. The brilliant star at far right is Propus.
