Hubble @NASAHubble

Telescope teamwork ✅ Hubble and @NASAWebb captured the galaxies in this image, while @chandraxray detected the superheated gas that these galaxies are immersed in, seen in purple. Called MACS J0416, this cluster of galaxies is held together by gravity: go.nasa.gov/4dmwspq

We need your help! 🆘 In its mission to map out the #DarkUniverse, #ESAEuclid will image hundreds of thousands of distant galaxies 💫 For the next six years, the spacecraft is expected to send around 100 GB of data back to Earth every day! 🤯 That’s a lot of data, and we need…

NASA's Fermi Gamma-ray Space Telescope detected a powerful gamma-ray burst, known as "Brightest Of All Time" (BOAT), possibly caused by a supernova 2.4 billion light-years away. This event, GRB 221009A, exhibited an unprecedented emission line suggesting matter-antimatter…

The following images were taken with XMM-Newton to check the placement of the mirror shells by observing single-reflection arcs while looking at Scorpius X-1. The image is a composite of four off-axis EPIC-pn observations of Scorpius X-1 in the 0.3-12 energy band.

A first visit to Cité de L’espace this weekend. Had to get a picture with my favourite x-ray observatory. With Chandra’s future in doubt @ESA_XMM will only be more important to the community. #Astronomy

Devastating news that the Chandra X-ray Observatory has been defunded. The very real prospect of an X-ray desert in the near future should be of grave concern for all high energy astronomers.

Pretty depressing day at work today with lots of staff updating their resumes as we grapple with NASA's decision to shut down Chandra, the world's only ever high resolution X-ray space telescope, still returning fabulous science discoveries. Still hoping this can be reversed

📢New paper!📢 We published the discovery, with @eROSITA_SRG, of two more galaxies showing the repeated X-ray flares called quasi-periodic eruptions (QPEs). So.. what’s new on QPEs? A 🧵 arxiv.org/abs/2401.17275

This #eRASS1 animation shows the #Xray sky as seen by #eROSITA. The X-ray bands are colour-coded according to their energy (red: 0.3-0.6 keV, green: 0.6-1 keV, blue: 1-2.3 keV). And a number of prominent sources have been highlighted. 4/9 CC: Jeremy Sanders/eROSITA consortium
