A supernova is a massive explosion that occurs at the end of a star's life. The Chandra X-ray Observatory, a sophisticated space telescope, captured the aftermath of such an explosion in the constellation Cassiopeia.

On March 18, 2021, a Japanese amateur astronomer, Yuji Nakamura, spotted a new (new to us Earthlings, anyway) nova in the Cassiopeia constellation, dubbed Nova Cas 2021.

An article to be published in "The Astrophysical Journal" reports a study on Tycho supernova remnants which offers new information on the geometry of its magnetic fields. A team of astronomers led by Riccardo Ferrazzoli of the Italian National Institute of Astrophysics used observations conducted with the IXPE space telescope to examine the polarized X-rays emitted by these supernova remnants. This allowed new clues to be found about the conditions in the shock waves generated by the supernova that accelerate particles to speeds close to the speed of light.

The Tycho Supernova: Death of a Star

[netmassimo]

An article published in "The Astrophysical Journal Letters" describes a research on the Tycho supernova remnant. That explosion was seen on Earth in 1572 in an event well documented. The expansion of the remaining materials is still interesting and a team of astronomers studied it with NASA's Chandra X-ray Observatory, the NSF's Karl G. Jansky Very Large Array (VLA) and many other telescopes to create a kind of film that shows it.

One supernova type, two different sources

The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They're bright enough to see across large distances, and similar enough to act as a "standard candle" - an object of known luminosity. The 2011 Nobel Prize in Physics was awarded for the discovery of the accelerating universe using Type Ia supernovae. However, an embarrassing fact is that astronomers still don't know what star systems make Type Ia supernovae.

Two very different models explain the possible origin of Type Ia supernovae, and different studies support each model. New evidence shows that both models are correct - some of these supernovae are created one way and some the other.

"Previous studies have produced conflicting results. The conflict disappears if both types of explosion are happening," explained Smithsonian astronomer and Clay Fellow Ryan Foley (Harvard-Smithsonian Center for Astrophysics).
