    Congratulations Peter on your huge success in bringing to fruition, and the already amazing data and results! Enjoy a well-earned change-of-pace. We will miss you. Welcome . looks forward to working with you and the team.

    Many thanks for the legacy of Peter Predehl, who is stepping down as PI of and congratulations and good luck to for taking over this role in the future! What a wonderful team!

    What a lovely way to watch at work!

    A 164 ksec observation of Cas A. Each frame adds 5 minutes of time. The speed with which a feature appears mostly depends on its surface brightness, weighted by spectral shape * detector response. I love the austerity of X-ray astronomy. Every photon brings ROI.

    There are many hidden gems in !

    Serendipity abounds in the archive. Take the highly successful 1999 observations of the Galilean moons (). The Chandra HIPS show SDSS J013842.69+084324.1 and possibly sources

    Impressive! ---- not just the contribution to this analysis......

    In one day I downloaded data of 10 observations, created mosaic images and exposure maps, ran source detection, and created a beautiful mosaic image of only the diffuse emission of a nearby galaxy. I love and .

    Stars are forming at a tremendous rate in Henize 2-10, giving star clusters in this galaxy their blue appearance. About 30 million light years from Earth, the supermassive black hole at the galaxy's center is about one million times the mass of our Sun.

    Sad news from Moscow. Misha Pavlinsky passed away earlier today. He PI’ed ART-XC, and was the one who did most of the leg work for SRG *by far*, especially in the critical early years. Years of overwork and stress have taken the toll... without Misha, SRG would not have happened.

    Even though the 'first results' conference suffered from the impact of COVID-19, you can still read about the interesting things e-ROSITA has been doing: Merloni, Nandra and Predehl have you covered.

    Tomorrow is day 1 of . Stop by and explore the all new virtual booth. You can talk with Chandra staff, learn about the Chandra Source Catalog, talk to an astro-statistician, walk among the stars, and ask any X-ray data analysis questions you may have.

    This amazing galaxy cluster was discovered by as part of the COSMOS survey!

    This image contains the most distant galaxy cluster, a discovery made using data from NASA’s Chandra X-ray Observatory and several other telescopes. The galaxy cluster, known as CL J1001+0220, is located about 11.1 billion light-years from Earth and may have been caught right after birth, a brief, but important stage of cluster evolution never seen before.
    Next stop: CL J1001+0220, about 19 billion light-years away! 🌌 This is the most distant galaxy cluster, which was caught shortly after it was born! 👶 Not only that, but it has remarkable levels of star formation compared to older clusters.

    The is a huge, rich dataset with many hidden discoveries to find!

    ObsID 2263 () is a short early Chandra observation of the AGN AGX J170730+2353. The field was previously probed by ROSAT (bibcode: 2001PASP..113.1386M) but there are several sources here waiting to be explored.
