Supernova Explosion & # 39; gifted & # 39; Earth with gold, platinum

An overlooked space-distant stellar explosion may have given Earth the gift of precious heavy elements such as gold and platinum, as a study claims. Throws our understanding of how heavy elements appeared on our planet upside down. According to research published in the journal Nature, about 80 percent of the heavy elements in the universe are likely to have formed …

The heavy metals of the earth are the result of a supernova explosion

Artistic representation of a collapsar. Credit: NASA Goddard Space Flight Center This gold on your ring finger is superb – and not just in a free way. In a discovery that might topple our understanding of where the Earth's heavy elements such as gold and platinum come from, recent research by a physicist at the University of Guelph suggests that …

"First Ever" –Violent Supernova, which is observed by Magellan telescopes, can end many years of mystery

Posted on May 7, 2019 Type Ia supernova play a crucial role in helping astronomers understand the universe. Their brilliance allows them to be seen across great distances and used as cosmic milestones, earning the 2011 Nobel Prize in Physics. Their violent explosions synthesize many of the elements that make up the world around us and are ejected into the …

Could this rare supernova resolve a longstanding original debate?

This cartoon courtesy by Anthony Piro illustrates three possibilities for the origin of the mysterious hydrogen emissions from the Type Ia supernova called ASASSN-18tb that were observed by the Carnegie astronomers. Starting from the top and going clockwise: The collision of the collision with a hydrogen-rich companion star, the explosion triggered by two colliding white dwarf stars subsequently colliding with …

"Cannonball" pulsar points to the supernova that shaped it

Pulsars are superdense neutron stars formed from massive supernovae. They can only be found if their electromagnetic radiation points directly to Earth like a nuclear lighthouse. It has been found that pulsars rotate as fast as 1.6 milliseconds or 38,500 rpm. They absorb the angular momentum of the massive stars that formed them, but are only a fraction of the …

Whirling Pulsar escapes from the supernova area at epic speed

A supernova explosion threw up a super-dense, swirling star core and swept it through space at nearly 4 million km / h (12 million km / h), with a fiery 13-light-year trail in progress. The researchers traced the star nucleus, called Pulsar with NASA's Fermi-Gamma-Ray Space Telescope and the National Science Foundation's Very Large Array (VLA) astronomical observatory. The Pulsar …

The pulsar is faster away from the supernova that created it

When a star consumes its nuclear fuel towards the end of its life, it undergoes a gravitational breakdown and discards its outer layers. This leads to a great explosion, known as the supernova, which can lead to the creation of a black hole, a pulsar, or a white dwarf. And despite decades of observation and research, there are still not …

Water could have drowned the earth, if not for the ancient supernova

Radioactive metal could help to explain why the earth and its sibling worlds are not hostile marine planets, as a new study shows. Earth is the only world known to cover most of it with life. Since there is life virtually everywhere on earth, the search for potentially habitable planet is primarily focused on worlds that may have water on …

Cosmic dust survives the extinction in a huge red supernova, as NASA shows in breathtaking looks

All we are is cosmic dust in the wind. When red giant stars die off, dust particles form; These particles are later destroyed by supernova explosion waves that, according to NASA, travel through space at more than 6,000 miles per second. Supernova explosions are among the most powerful events in the universe and can produce a brightness that matches the …
