Euclid Releases First Astronomical Data Catalogue, Hera Captures Deimos, and Hubble Observes NGC 4900

The European Space Agency (ESA) has released the first catalogue of astronomical data from the Euclid space telescope, featuring three image mosaics with zoom-ins. These previews cover 63 square degrees of the sky and will assist scientists in answering astronomical questions. The Hera spacecraft, during its Mars flyby on March 12, 2025, captured images of Deimos, a Martian moon, using its Thermal Infrared Imager (TIRI), supplied by JAXA. The images, taken from approximately 1000 km away, show Deimos appearing brighter and hotter than Mars due to its low reflectivity and lack of atmosphere. Additionally, a recent Hubble Space Telescope image showcases the spiral galaxy NGC 4900 alongside a star in our galaxy. NGC 4900 is 45 million light-years away, while the star is 7109 light-years distant. The image combines data from Hubble's Advanced Camera for Surveys and Wide Field and Planetary Camera 2, taken over 20 years apart, to study supernovae and their progenitors.
