Weird turbulations

An accumulation of 270 hours of Chandra observations of the central regions of the Perseus galaxy cluster reveals evidence of the turmoil that has wracked the cluster for hundreds of millions of years. One of…


Eating each other

This composite image of M31 (also known as the Andromeda galaxy) shows X-ray data from NASA’s Chandra X-ray Observatory in gold, optical data from the Digitized Sky Survey in light blue and infrared data from…


Black buster

The galaxy at the center of this image contains an X-ray source, CID-42, with exceptional properties. After combining data from several telescopes — including NASA’s Chandra X-ray Observatory — researchers think that CID-42 contains a…


Turn up the overall heat

Black holes will be our demise. We should stop them. We’re not talking global warming but universal warming. We should form a committee. So far, astrophysicists thought that super-massive black holes can only influence their…


Becoming spaghetti

A star wanders too close to a black hole. And before you know it, you are one long piece of spaghetti. Enjoy your meal. Astronomers have gathered the most direct evidence yet of a supermassive…


Glutton^2

One of the biggest conundrums facing astrophysicists is how the most massive black holes became so, well, massive. Now it seems we have a potential answer — these greedy behemoths may have gobbled down two…


Rogue Planet Blues

In this artist’s conception, a runaway planet zooms through interstellar space. New research suggests that the supermassive black hole at our galaxy’s center can fling planets outward at relativistic speeds. Eventually, such worlds will escape…
