  • Astronomers see for the first time that a star is dying and going supernova
  • The supernova, known as SN 2020fqv, is 60 million light-years away from Earth
  • The Hubble Space Telescope and NASA’s TESS both observed the supernova
  • Researchers believe the supernova’s behavior may be a precursor to other supernovae and create a ‘warning system’.

Astronomers using the Hubble Space Telescope and other space-peering instruments have observed for the first time that a star 60 million light-years away is dying and going supernova in ‘real time’, a ‘warning system’ for other stars. can provide.

The supernova, known as SN 2020fqv, is in the interacting Butterfly Galaxies and the constellation Virgo.

By taking pictures before and after the explosion, scientists were able to obtain an ‘unprecedented’ description of the event.

It was initially discovered in April 2020 by the Zwicky Transient Facility at Palomar Observatory in San Diego, California.

Astronomers see for the first time that a star is dying and going supernova

Ryan Foley, assistant professor of astronomy and astrophysics at UC Santa Cruz, said, “We used to talk about how supernovae work like we were crime scene investigators, where we show up after the fact and try to figure out why. What happened to that star? said in Statement.

‘It’s a different situation, because we know exactly what’s going on and we actually see death in real time.’

The star died out millions of years ago, but the light is only visible now, given how deep it is in space.

NASA’s Transiting Exoplanet Survey Satellite (TESS), which is used to study and search for exoplanets, was also observing the supernova, giving astronomers a multidimensional view of the explosion.

“We rarely get a chance to probe this very close circumstellar material because it is only visible for a very short period of time and we usually see supernovae until at least a few days after the explosion,” said Samporn, first author of the study. Don’t start watching. Tinianont said.

‘For this supernova, we were able to make ultra-rapid observations with Hubble, which led to unprecedented coverage of the region right next to the exploding star.’

According to the statement, Hubble, a joint venture between NASA and the European Space Agency, was also able to see material close to the star, known as circumstellar material, ‘just a few hours after the explosion’.

This helped astronomers understand what was going on with the star just before it died.

NASA’s TESS took an image of the star every 30 minutes ‘for several days before the explosion and for several weeks after it.

The researchers looked to Hubble data back in the 1990s (it was launched in April 1990) to obtain a ‘multi-decade look’ of the star’s final years.

“We now have the full story of what’s going on in the years before we die, at the time of death, and in the years after,” Foley said.

‘This is really the most detailed view of stars like this in their final moments and how they explode.’

Known as ‘The Rosetta Stone of Supernovae’, the SN 2020fqv supernova allowed researchers to learn more about the store, including how the mass of the star (about 14 or 15 times the mass of the Sun) is reduced in a number of ways. Verifying is involved, which helps astronomers learn more. About how stars live and die.

“This is the first time we’ve been able to verify the mass for a supernova with these three different methods, and they’re all consistent,” Tinianont said.

‘We can now proceed using these different methods and combining them, as there are many other supernovae where we have mass from one method but not the other.’

The researchers believe that the behavior of the supernova they observed may be a precursor to other supernovae and may, in fact, form a kind of ‘warning system’, Foley said.

‘So if you see a star start to move a little bit, start acting out, maybe we should pay more attention and really try to understand what’s going on there before it explodes.

‘As we find more and more of these supernovae with this type of excellent data set, we will be able to better understand what is happening in the last few years of a star’s life.’

A study related to the findings will eventually be published in the Monthly Notices of the Royal Astronomical Society.

NASA’s Hubble Space Telescope is still operating and has made more than 1.3 million observations since the start of its mission in 1990

The Hubble Telescope was launched on April 24, 1990, from the Kennedy Space Center in Florida via spacecraft Discovery.

It is named after the famous astronomer Edwin Hubble who was born in Missouri in 1889.

He is arguably most famous for discovering that the universe is expanding and the rate at which this is happening—now coined the Hubble constant.

Hubble has made more than 1.3 million observations since the start of its mission in 1990 and helped publish more than 15,000 scientific papers.

It orbits the Earth at a speed of about 17,000mph (27,300kph) in low Earth orbit at an altitude of about 340 miles.

Hubble’s pointing accuracy is .007 arc seconds, which is akin to being able to shine a laser beam focused onto the head of Franklin D. Roosevelt on a dime about 200 miles (320 km) away.

The Hubble Telescope is named after Edwin Hubble who was responsible for coming up with the Hubble constant and is one of the greatest astronomers of all time.

Hubble’s primary mirror is 2.4 m (7 ft, 10.5 in) wide and is 13.3 m (43.5 ft) tall overall – the length of a large school bus.

The launch and deployment of Hubble in April 1990 marked the most significant advance in astronomy since Galileo’s telescope.

Thank you for servicing five missions and more…
