Cosmic radiation occasionally contains enormous amounts of energy, but we don’t know why or where this radiation comes from.

In 1953, after years as a teacher and later as a stay-at-home mom, she began working for NASA's predecessor, the National Advisory Committee for Aeronautics, or NACA. The NACA had taken the unusual ...

A binary system 18,000 light-years away, emits X-rays as a Sun-like star orbits a dense companion, either a neutron star or black hole. Telescopes like Chandra, IXPE, and XMM-Newton capture its ...

Astronomers searching for massive black holes shredding stars found one in an unusual place -- 2,600 light years from the core of a galaxy. The roque black hole may be from an earlier merger with ...

Chandra X-ray Observatory observations of the Perseus galaxy cluster's black hole and M87's jet have been turned into sound by SYSTEM Sounds. Credit: NASA/CXC/SAO/K.Arcand, SYSTEM Sounds (M. Russo, A.

Astronomers have detected a rare black hole outside a galaxy’s core devouring a star in the first known offset tidal ...

New data from space telescopes has been transformed into cosmic soundscapes, turning the mysterious activity around black ...

What is Space Jaws? A covert black hole revealed itself to astronomers in 2025 with a spectacular burst of radiation known as a tidal disruption event ...

IXPE saw record 47.5% optical polarization in blazar BL Lacertae in 2023 X-ray polarization stayed low, confirmed Compton scattering by electrons Findings rule out proton models and deepen insight ...

It sounds like something from a sci-fi thriller. A giant black hole quietly drifted through space before tearing a star apart. Now, thanks to NASA telescopes, this silent predator has been caught ...

NASA's Hubble captured a rare event 600 million light-years away: a black hole devouring a star in a Tidal Disruption Event (TDE). This "offset" TDE, named AT2024tvd, suggests the black hole isn't ...

allowed astronomers to pinpoint a wandering supermassive black hole using NASA’s Hubble Space Telescope, with similar supporting observations from NASA’s Chandra X-Ray Observatory and the NARO Very ...
