Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, ...

Astronomers are trying to understand a mysterious cosmic explosion that the Einstein Probe spacecraft spotted in April last year.

The Einstein Probe is revolutionizing our view of the distant X-ray universe, offering an unprecedented look at some of the ...

An open-access report of their findings, published Jan. 27 in The Astrophysical Journal Letters, indicates that the characteristics of this explosion do not match those of typical gamma-ray bursts.

Gamma-Ray Bursts (GRBs): Extremely powerful explosions in distant galaxies that emit vast amounts of energy, mainly as gamma rays. Hypernovae (Massive Star Explosions): Ultra-powerful stellar ...

For the first time, the consequences of combining two well-established empirical relations, describing different aspects of the spectral evolution of observed gamma-ray burst (GRB) pulses, are ...

The burst was linked to GRB 240315C, a gamma-ray burst, but its characteristics—like a 6-minute delay between X-rays and gamma rays—challenge existing theories of GRB formation. Weimin Yuan, ...

Feb. 4, 2025 — NASA's Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an 'arrow' -- a far smaller blue ...
