An article published in “The Astrophysical Journal Letters” reports the results of a study on the region of very hot plasma that surrounds a black hole called the corona. A group of researchers used detections conducted with the IXPE space telescope to obtain precise information on the corona of 12 black holes ranging from stellar-mass ones to supermassive black holes. For the first time, it was possible to observe the geometry of the corona of black holes and its relationship with the accretion disk that surrounds them. The geometry seems very similar regardless of the size of the black holes but this is still a tentative result.

A few hours ago, NASA’s Europa Clipper space probe blasted off atop a SpaceX Falcon Heavy rocket from the Kennedy Space Center. After just over an hour, it successfully separated from the rocket’s last stage and set off on its route that will take it into deep space, to Europa, Jupiter’s moon with an icy surface that hides an ocean of liquid water to understand if it’s habitable.

An article published in “The Astrophysical Journal” reports the discovery of the triple system cataloged as TIC 290061484, the most compact of its kind found so far. A team of researchers coordinated by NASA’s Goddard Space Flight Center used observations with NASA’s TESS space telescope, applied a machine learning technique, and involved citizen scientists who participated in the Planet Hunters project in a new project called the Visual Survey Group. This rare triple system will help astronomers better understand the processes of formation and evolution of multiple systems.

A few hours ago, SpaceX’s Crew Dragon Freedom spacecraft docked with the Harmony module of the International Space Station completing the first part of its Crew-9 or SpaceX Crew-9 mission that began with its launch about 28 hours earlier. After checking that the pressure gets properly balanced, the hatch will be opened to allow Nick Hague and Aleksandr Gorbunov to enter the Station and start their mission, which will last about five months.

A little while ago, SpaceX’s Crew Dragon Freedom spacecraft blasted off atop a Falcon 9 rocket from the Kennedy Space Center in its Crew-9 or SpaceX Crew-9 mission. After almost exactly twelve minutes, it successfully separated from the rocket’s last stage and went en route to carry out its mission. This is the 9th crewed mission of the Crew Dragon spacecraft within the normal rotation of the International Space Station crew.
