NASA’s IXPE Details Shapes of Structures at Newly Discovered Black Hole
NASA’s IXPE (Imaging X-ray Polarimetry Explorer) has helped astronomers better understand the shapes of structures essential to a black hole – specifically, the disk of material swirling around it, and the shifting plasma region called the corona. The stellar-mass black hole, part of the binary system Swift J1727.8-1613, was discovered in the summer of 2023 during an unusual brightening event…

NASA’s IXPE Helps Researchers Determine Shape of Black Hole Corona
New findings using data from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) mission offer unprecedented insight into the shape and nature of a structure important to black holes called a corona. A corona is a shifting plasma region that is part of the flow of matter onto a black hole, about which scientists have only a theoretical understanding. The new results…

IXPE Operations Update
On March 23, NASA’s IXPE (Imaging X-ray Polarimetry Explorer) stopped transmitting valid telemetry data. The only previous interruption of IXPE science observations was due to a similar issue in June of 2023. On March 26, using procedures developed following that previous interruption, the team initiated a spacecraft avionics reset to address the issue, which put IXPE into a planned safe mode. The…

NASA’s IXPE Marks Two Years of Groundbreaking X-ray Astronomy
On Dec. 9, astronomers and physicists will commemorate two years of landmark X-ray science by NASA’s IXPE (Imaging X-ray Polarimetry Explorer) mission. IXPE is the joint NASA-Italian Space Agency mission to study polarized X-ray light. Polarization is a characteristic of light that can help reveal information about where that light came from, such as the geometry and inner workings of the ultra-powerful…

NASA X-ray Telescopes Reveal the “Bones” of a Ghostly Cosmic Hand
In 1895, Wilhelm Röntgen discovered X-rays and used them to image the bones in his wife’s hand, kicking off a revolutionary diagnostic tool for medicine. Now two of NASA’s X-ray space telescopes have combined their imaging powers to unveil the magnetic field “bones” of a remarkable hand-shaped structure in space. Together, these telescopes reveal the behavior of a dead collapsed…

IXPE Untangles Theories Surrounding Historic Supernova Remnant
NASA’s IXPE (Imaging X-ray Polarimetry Explorer) telescope has captured the first polarized X-ray imagery of the supernova remnant SN 1006. The new results expand scientists’ understanding of the relationship between magnetic fields and the flow of high-energy particles from exploding stars. “Magnetic fields are extremely difficult to measure, but IXPE provides an efficient way for us to probe them,” said…

NASA Launches New Mission to Explore Universe’s Most Dramatic Objects
NASA’s Imaging X-ray Polarimetry Explorer (IXPE) mission launched at 1 a.m. EST Thursday on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. A joint effort with the Italian Space Agency, the IXPE observatory is NASA’s first mission dedicated to measuring the polarization of X-rays from the most extreme and mysterious objects in the universe – supernova…
