Turbulent Mixing Inside Stars Causes them to Expand, Contract, Eject and Explode, According to 3-D Model Described in the Journal "AIP Advances" WASHINGTON, March 18, 2014 /PRNewswire-USNewswire/ -- A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible....

Supernova Dust Factory

[ Watch the Video: Supernovas May Be Galactic Dust Factories ] Lee Rannals for redOrbit.com - Your Universe Online A new image of a recent supernova could offer up insight to scientists about how galaxies became so dusty. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have observed the remains of supernova 1987A located in the Large Magellanic Cloud about 168,000 light-years from Earth. This is the closest observed supernova explosion since Johannes...

Largest Known Star Self Destructs
2013-10-16 12:49:05

Lee Rannals for redOrbit.com - Your Universe Online A group of international scientists have been observing as the largest known star in the Universe tears itself apart. Astronomers from the UK, Chile, Germany and the US have watched as W26 in the Westerlund 1 star cluster shed its outer layers and flings a huge cloud of glowing hydrogen gas out to return enriched material back to the interstellar medium. The latest observation, reported in the journal Monthly Notices of the Royal...

Astronomers Detect Relatively Cool Supernova Remnant
2013-07-05 14:00:28

Lee Rannals for redOrbit.com - Your Universe Online An international team of astronomers detected surprisingly low temperatures in the remnant of the supernova 1987A, helping to explain the mystery of why space is filled with dust grains and molecules. The team used the Herschel Space Observatory and Atacama Millimeter and Submillimeter Array (ALMA) to study the supernova remnant. They were able to find a vast reservoir of unexpectedly cold molecules and dust. "The powerful explosion...

First High-Resolution Radio Images Of Supernova 1987A Released

Lawrence LeBlond for redOrbit.com - Your Universe Online An observation of the Large Magellanic Cloud (LMC) in February of 1987 left astronomers thinking they had discovered the beginnings of a new star. However, what they had witnessed was the end of one of the brightest supernovae seen from Earth since the invention of the telescope some 400 years earlier. And in the two-plus decades since the discovery of the remnant Supernova 1987A, researchers have continued their gaze on one of the...

Supernova Gives Scientists Clues Into Origins Of Cosmic Rays
2013-02-14 13:19:29

[ Watch the Video: Fermi Proves Supernova Remnants Produce Cosmic Rays ] Lee Rannals for redOrbit.com - Your Universe Online A thousand-year-old supernova has given the European Space Observatory's Very Large Telescope (VLT) ample opportunity to gain some clues about the origins of cosmic rays. The new observations, reported in the journal Science today, suggest the presence of fast-moving particles in the supernova remnant. Over a thousand years ago, in 1006 AD, a new star was...

Supernova Remnant Powered By Radioactive Decay Of Titanium
2012-10-18 04:20:39

April Flowers for redOrbit.com - Your Universe Online Radioactive titanium associated with supernova remnant 1987A has been directly detected by ESA's Integral space observatory. The glowing remnant around the exploded star has likely been powered by the decaying from this titanium for the last 20 years. The first space observatory that can simultaneously observe objects in gamma rays, X-rays and visible light, Integral's principal targets are violent explosions known as gamma ray...

Earth Safe And Sound From Supernova In 2012: NASA
2011-12-19 12:30:19

[ Watch the Video ] NASA reported recently that astronomers can say with certainty there is no fear of a supernova being close enough to hurt Earth, especially by 2012. Astronomers believe that about one or two supernovae explode each century in our galaxy.  However, for Earth's ozone layer to experience damage from a supernova, the blast must occur less than 50 light-years away. All of the nearby stars capable of going supernova are much farther than 50 light-years. A...

ESA's Herschel Space Observatory has detected cosmic dust from a supernova, adding to the theory that these cosmic fireworks are responsible for its creation. The astronomers who used Herschel to make the discovery said origin of the dust is important because it plays a crucial role in the formation of stars, particularly billions of years ago when star formation was at its peak.  "Interestingly, this brand new clue does not come from observations of very distant galaxies, but from one...

The wispy arms of the Tarantula Nebula were originally thought to resemble spindly spider legs, giving the nebula its unusual name. The part of the nebula visible in this image from Hubble's Advanced Camera for Surveys is criss-crossed with tendrils of dust and gas churned up by recent supernovae. These supernova remnants include NGC 2060, visible above and to the left of the center of this image, which contains the brightest known pulsar. The tarantula's bite goes beyond NGC 2060. Near the...

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

Supernova 1987a -- Supernova 1987a was a supernova in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 50 kiloparsecs from Earth, the closest supernova since Supernova 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. Its brightness peaked in May with a magnitude of about 3 and slowly declined in the following months. It was modern astronomers' first opportunity to see a supernova up close....
