    NASA-JAXA XRISM Mission Sees Pulsar Gathering Companion’s ‘Wind’

    Using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory, astronomers have directly observed a giant star’s outflow, called a stellar wind, being captured by its compact companion and providing the power source for strong X-ray flares. The…

    NASA’s IXPE May Have Proven 90-Year-Old Theory

    A first-of-its-kind measurement of a magnetar may have captured empty space behaving in a way physicists have predicted for 90 years, but never directly observed. The results published Wednesday in Nature. Fast facts Scientists using NASA’s IXPE (Imaging X-ray Polarimetry…

  • NASA’s Fermi Glimpses Power Source of Supercharged Supernovae

    NASA’s Fermi Glimpses Power Source of Supercharged Supernovae

    An international team studying data from NASA’s Fermi Gamma-ray Space Telescope concludes the mission detected a rare, unusually luminous supernova. The researchers say it likely received its power-up from a supermagnetized neutron star born in the stellar collapse that triggered…

  • NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion

    NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion

    A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it…

  • NASA’s Webb Observes Exoplanet Whose Composition Defies Explanation

    NASA’s Webb Observes Exoplanet Whose Composition Defies Explanation

    Scientists using NASA’s James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our understanding of how it formed. Officially named PSR J2322-2650b, this Jupiter-mass object appears to have…

  • NASA’s Hubble Tracks a Roaming Magnetar of Unknown Origin

    NASA’s Hubble Tracks a Roaming Magnetar of Unknown Origin

    Researchers using NASA’s Hubble Space Telescope have discovered the magnetar called SGR 0501+4516 is traversing our galaxy from an unknown place of origin. Researchers say that this runaway magnetar is the likeliest candidate in our Milky Way galaxy for a…
