Wait, which one is it? Science or Scientific #XMM

Supernovae kunnen gevaarlijk zijn voor de bewoonbaarheid van planeten

De nasleep van supernovae produceert altijd röntgenstraling, maar als de schokgolf van de supernova op dicht omringend gas inslaat, kan deze een bijzonder grote dosis röntgenstraling produceren die maanden tot jaren na de explosie aankomt

We are excited to announce our upcoming workshop on High-Resolution X-ray Spectroscopy, to be held in a hybrid format out of MIT in Cambridge, MA! Topics will include everything from Massive Stars to Clusters of Galaxies, with science results from #Chandra and from our friends at #XMM, #XRISM, and elsewhere.

Follow the conference webpage to stay up to date on Invited Speakers, Deadlines, and the eventual Program! https://cxc.harvard.edu/cdo/hrxs2023/index.html

Did you catch our recent #ChandraScience image of Abell 2256, a spectacular merger of at least three galaxy clusters? The hot gas components of these clusters is traced with X-rays -- shown here in blue, using data from us (#Chandra) and our ESA-led friends at #XMM-Newton. This cosmic collision is also a source of radio emission, shown in red from #LOFAR, #GMRT, and the #VLA, produced via particle acceleration. For more details, see

The last two days reminded me that things that are obvious to me often aren't to other people - not even other physicists! For example, did you know that data from the ESA (and NASA) space telescopes is freely available online, usually after a short proprietary period for folks who proposed the observation? They are.

For example, the #XMM archive is here: http://nxsa.esac.esa.int/nxsa-web

And the ESA #Hubble archive here: https://hst.esac.esa.int/ehst/#/pages/home
