X-ray emission also allows a supernova shock to be used as a probe of interstellar medium structure. The imaging instrument aboard the Einstein satellite has been used to observe over 30 known Galactic remnants, and a similar number of objects in other galaxies, in the 0.15-4.5 keV band....
Then, there are the supernova remnants, like the Crab Nebula. These nebulae are made of debris from exploded stars. In the year 1054 AD, Chinese astronomers recorded a “guest star” that was visible even in the daytime sky for nearly a month. The “guest star” they observed was actuall...

The James Webb Space Telescope's view of the Crab NebulaCredit: NASA / ESA / CSA / STScI / T. Temim (Princeton University) In the year 1054 CE, astronomers saw a strange bright light appear in the sky. We now know it was a star's explosion, a dramatic event called asupernova, wh...

The XRISM space telescope's X-ray spectrum of supernova remnant N132D. (Image credit: JAXA/NASA/XRISM Resolve and Xtend) "These elements were forged in the original star and then blasted away when it exploded as a supernova," Brian Williams, NASA’s XRISM project scientist, said in a...
In this year’s workshop, that “not as cold as you expect” claim was challenged on our very first day of shooting, when we piled out of the bus at our first stop into 5°F air. Fortunately, that’s the coldest we experienced all workshop, and great photography creates an inexplicab...
Another stargazing favorite, theCrab Nebulais not visible to the naked eye, and requires a good-quality telescope. What we see in this Hubble photograph is the remains of a massive star that blew itself up in a supernova explosion that was first seen on Earth in the year 1054 A.D. A ...

the shockwave from the explosion can reach out far into space and interact with nearby dust and gas to form a supernova remnant. These shells appear around the site where the star exploded, and this image combines optical, infrared, and X-ray observations to show the different parts of the...
