Several telescopes used to observe the supernova SN Zwicky which was magnified nearly 25 times by a foreground galaxy acting ...
A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...
An international team of astronomers has conducted photometric and spectroscopic observations of a recently discovered ...
Supernova 1987A appeared in the far-southern constellation of Doradus (the Swordfish), in which the Large Magellanic Cloud is ...
In A Nutshell A massive star in the Andromeda Galaxy faded by more than 10,000 times over a decade and vanished from view, ...
A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...
Kishalay De, an alumnus of St James’ School and currently at Columbia University, has helped solve the mystery, showing that ...
This is a massive star that exploded 35,000 years ago, and the deep-sky image just won an award – a first in the prestigious ...
In 2014, a NASA telescope observed that the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around ...
DS1, collapsed into a black hole without exploding, revealing how stars die in silent “failed supernova” events.
The formation of a black hole can be quite a violent event, with a massive dying star blowing up and some of its remnants collapsing to form an exceptionally dense object with gravity so strong not ...
The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s that theorized that when a star underwent direct collapse, it would leave ...
