The brightest supernova remnant in the Large Magellanic Cloud provides a stunning target for the Hubble Space Telescope’s super-sharp vision.

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.

Of supernova remnants and stellar nurseries in the Large Magellanic Cloud

2 September 2020 Astronomy Now

One of the Large Magellanic Cloud’s lesser known regions, NGC 2035, shows off a stellar nursery in vast clouds of gas and dust along side a colourful supernova remnant in this close-up view from the European Southern Observatory’s Very Large Telescope.

Debris in Kepler supernova remnant clocked at 23 million mph

Debris in supernova remnant still moving at more than 20 million mph 400 years after Type 1a explosion.

Supernova remnant dazzles in Large Magellanic Cloud

20 February 2020 Astronomy Now

A supernova remnant in the Large Magellanic Cloud displays a beautiful tapestry of wispy gas that will provide the raw material for another generation of stars.

Citizen scientists showcased for spectacular images

3 November 2019 Astronomy Now

The Chandra X-ray Observatory project is showcasing citizen scientists who help astronomers by sifting through public data archives and processing spectacular, scientifically valuable images that can lead to new discoveries.

Chandra X-ray telescope sheds new light on the Tycho supernova remnant

20 October 2019 Astronomy Now

New images from NASA’s Chandra X-ray Observatory reveal the “lumpy” nature of the Tycho supernova remnant in spectacular detail, providing new insights into the evolution of Type 1a supernovae.

Discovering the X-ray treasures in Chandra’s archives

16 October 2016 Astronomy Now

Each year, NASA’s Chandra X-ray Observatory helps celebrate American Archive Month by releasing a collection of images using X-ray data. Each of these six new images — representing just a small fraction of the treasures that reside in Chandra’s unique archive — also includes data from telescopes covering other parts of the electromagnetic spectrum, such as visible and infrared light.

Supernova ejected from the pages of history

18 August 2016 Astronomy Now

A new look at the debris from an exploded star in our galaxy has astronomers re-examining when the supernova actually happened. Recent observations of the supernova remnant called G11.2-0.3 with NASA’s Chandra X-ray Observatory have stripped away its connection to an event recorded by the Chinese in 386 CE.

Chandra captures expanding debris from Tycho’s supernova remnant

13 May 2016 Astronomy Now

Astronomers have observed the debris field from the supernova of 1572, now known as Tycho’s supernova remnant, with NASA’s Chandra X-ray Observatory and the NSF’s Karl G. Jansky Very Large Array (VLA). By combining the X-ray data with some 30 years of observations in radio waves, astronomers have also produced a movie showing the expansion from the explosion is still continuing 444 years later.
