Beetlejuice: The star continues to behave mysteriously - here's what will happen if it explodes

At the end of 2019, the light of the star dimmed and went from the brightest in the Orion group to the third brightest. Since then it has returned and become even brighter than before
A star exploding is a dramatic event, but the debris the star leaves behind can be even more dramatic. A new mid-infrared image from the James Webb Space Telescope provides one stunning example. It shows the remains of the supernova Cassiopeia A (Cas A), created by a stellar explosion 340 years ago. The image shows bright colors and complex structures. Cas A is the youngest known remnant of a massive exploding star in our galaxy, offering astronomers an opportunity to understand the star's death process. Image credit: NASA, ESA, CSA, D. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (UGent), J. DePasquale (STScI)

Webb recorded what remained after the death of a star only 11 thousand light years away from us. It is a relatively new supernova - only 350 years old

A boom in the middle of the universe: a supernova of a rare type has been discovered

Weizmann Institute scientists have identified a new type of supernova in a galaxy a billion light years away

Do you see the shape of a hand in the new x-ray image? The hand may look just like an x-ray at the doctor's, but it is actually a cloud of material ejected from an exploding star. The array of telescopes capable of nuclear spectroscopy Nuclear Spectroscopic Telescope Array or NuSTAR for short (NuSTAR) photographed the structure in the field of high X frequencies for the first time. Earlier image, lower-energy X-rays taken by the Chandra Space Telescope are seen in green and red in the image. Photo: NASA/JPL-Caltech/McGill
