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 light billions of single stars, NASA said, adding that the blast from these explosions will destroy almost everything in their path.

Observations of SOFIA – a Boeing747SP jetliner modified to carry a 106-inch telescope – reveal a secret story and more than 10 times the expected dust.

The new study is based on scientific observations from Supernova 1

987A, one of the brightest supernovae seen in 400 years when it was found more than 30 years ago. It also has an unmistakable set of rings that are part of a cavity created in an earlier phase prior to the explosion of the stars.

The research was published in a recent issue of the Monthly Notices of the Royal Astronomical Society .

According to the Space Agency, dust particles could form in the wake of the blast wave, giving astronomers new insights into the dust movement moving through the room. The dust could Either come from the growth of existing particles or arise from dust, says the space agency.

"We already knew about the slowly moving dust in the heart of 1987A," said Mikako Matsuura, senior lecturer at The Cardiff University in the UK, and the newspaper's lead author told NASA. "It arose from the heavy elements that arose in the core of the dead star. However, the SOFIA observations show something new about a totally unexpected dust population.

NASA plans future observations of cosmic dust with its James Webb Space Telescope.
