The Crab Nebula: shreds of a supernova

8 December 2022 Mark Armstrong

It’s perhaps a surprising but definitely disappointing fact that no person alive has seen the titanic explosion of a star as a supernova in our own Milky Way Galaxy.

A fourth-century supernova

6 July 2022 Keith Cooper

These delicate yet fast-moving filaments of gas belong to a supernova remnant designated as 1E 0102.2-7219, which resulted from the destruction of a massive star long ago in the Small Magellanic Cloud, 200,000 light years away.

Catch a bright supernova in Virgo

27 April 2022 Mark Armstrong

Supernova 2022hrs was discovered by amateur astronomer Koichi Itagaki on April 16.619 (14:50h UT) in NGC 4647, an intermediate spiral galaxy in the constellation of Virgo.

Rare luminous blue variable provides stellar spectacle for Hubble anniversary

27 April 2021 Astronomy Now

To mark the Hubble Space Telescope’s 31st anniversary in space, astronomers captured a dramatic image of a rare luminous blue variable, one of the most massive and brightest stars in the Milky Way.

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.

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).

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.
