Staring at stardust
Dust particles in space form the basis for new stars and planets. But what do these particles consist of and how do they behave? Sascha Zeegers studied this. Ph.D. defence 1 November.

A team of researchers led by Costanza Argiroffi, an astronomer at the University of Palermo in Italy, has found evidence of a coronal mass ejection (CME) from a star that was not our sun—the first ever observed. They reported ...
This image shows data from a massive observing campaign that includes NASA's Chandra X-ray Observatory. These Chandra data have provided strong evidence for the existence of so-called intermediate-mass black holes (IMBHs). ...
