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 ...

The asteroid, titled 387746 (2003 MH4), is gigantic. It is 335 metres in width, approximately 1,100 feet. That's almost the ...

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 ...

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 ...
