Hubble helps astronomers wind back clock on supernova blast

19 January 2021 Astronomy Now

Astronomers using the Hubble Space Telescope trace a supernova’s history by measuring how fast left over debris is moving, concluding light from the blast reached Earth during the decline of the Roman Empire 1,700 years ago.

Red supergiant Betelgeuse not so bright, not so giant, not so far away

16 October 2020 Astronomy Now

The red supergiant Betelgeuse, a prime supernova candidate in the not-too-distant future, may not be quite as large and far away as previously thought.

News

Cosmic dust up may best explain dimming of Betelgeuse

8 March 2020 Astronomy Now

Taking the temperature of Betelgeuse, astronomers say the supergiant’s recent dimming likely caused by thrown-off gas obscuring the view.

Going out with a bang, not a whimper, Eta Carinae continues to amaze

30 July 2019 Astronomy Now

The Hubble Space Telescope has captured another remarkable view of Eta Carinae, finding magnesium where it wasn’t expected and shedding new light on the “Great Eruption.”

Wreckage of a doomed star in the Large Magellanic Cloud

1 February 2019 Astronomy Now

A supernova remnant in the Large Magellanic cloud, imaged by the Hubble Space Telescope in 2006, shows the spectacular aftermath of a supernova blast, generating a cloud of debris expanding at 18 million kilometres per hour (11 million mph).

News

Astronomers see birth of rare binary neutron star

12 October 2018 Astronomy Now

Astronomers have found an “ultra-stripped supernova” that created a second neutron star in a tight binary system, matching theoretical predictions for how such binaries are formed in otherwise disruptive blasts.

News

Astronomers stunned again by Eta Carinae – the star that will not die

3 August 2018 Astronomy Now

Eta Carinae, one of the brightest, most massive stars in the Milky Way, famously erupted 170 years ago, producing huge clouds of expanding debris. Astronomers studying light echoes from the blast may have found an explanation.

Hubble spots possible third supernova exploding in remote galaxy

24 June 2018 Astronomy Now

Studying giant galaxy clusters to find targets for the upcoming James Webb Space Telescope, the Hubble Space Telescope spotted what appears to be a third supernova going off in a galaxy where two others were previously seen.

News

Hubble spots surviving companion to a supernova

26 April 2018 William Harwood

For the first time, the Hubble Space Telescope has photographed the surviving companion of a star that exploded in a supernova blast 17 years ago, evidence that supernovas can originate in binary star systems.

News

Kepler Space Telescope sheds light on fast-evolving supernovae

26 March 2018 Astronomy Now

NASA’s Kepler Space Telescope has captured a difficult-to-detect, fast-evolving supernova in the act of blowing up and rapidly fading away, allowing astronomers to rule out competing theories and come up with a plausible explanation.
