Coronal mass ejections (CMEs), often associated with solar flares, are the most powerful magnetic phenomena occurring on the Sun. Now, astronomers using NASA’s Chandra X-ray Observatory have spotted a gigantic CME erupting from the active star HR 9024. This is the first time a CME has been seen in a star other than our Sun. The results, published in the journal Nature Astronomy, confirm that CMEs are produced in magnetically active stars and are...

This image of the irregular galaxy NGC 4485 was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). NGC 4485 has been involved in a dramatic gravitational interplay with its larger galactic neighbor, NGC 4490, out of frame to the bottom right in this image. This ruined the original, ordered spiral structure of the galaxy and transformed it into an irregular one. Below NGC 4485 one can see a bright, orange background galaxy: CXOU J123033.6+414057. This galaxy is the source of X-ray radiation studied by NASA’s Chandra X-ray Observatory. It’s distance from Earth is about 850 million light-years. Image credit: NASA / ESA / Hubble.
