According to new simulations performed at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., the very first stars in our universe were not the behemoths scientists had once thought.
New infrared observations from NASA’s Spitzer Space Telescope and Wide-field Infrared Survey Explorer, or WISE, reveal how the first supernova, known as RCW 86, ever recorded occurred and how its shattered remains ultimately spread out to great distances.
German satellite plunged to Earth on October 22 after languishing in a dead orbit for more than a decade, but officials do not yet know where it fell.

Scientists at the Berkeley National Laboratory have discovered a new star located closer to Earth than any other. This supernova flared up on August 23 in the Pinwheel Galaxy, just 21 million light-years from Earth.
According to european and american scientists analysis of the radiation of a supernova SN1987A in the Large Magellanic Cloud the gas cloud, which was formed by an explosion, lights not only by radioactive decay of its matter, but under the influence of X-rays.Second type supernova SN1987A is located relatively close at a distance of 160,000 light years from Earth.
The Palomar Transient Factory discovered four hydrogen-poor superluminous supernovae, which is 10 times brighter than the famous type Ia supernovas that are relatively common in the cosmos.Astronomers can’t explain this new type of star explosion by any of the processes that control most supernovas
Tycho supernova, which is located about 13,000 light-years from Earth, formed when its parent star divided too much material from a nearby companion, forcing it to blow up in a massive thermonuclear explosion.
