Currently there exist two explanations behind the mysterious signals. The study strengthened one.

Add Yahoo as a preferred source to see more of our stories on Google. A bright band of diffuse gamma ray glow along the map's center, which marks the central plane of the Milky Way galaxy, is seen in ...

Cosmic rays are high-energy charged particles, predominantly protons and atomic nuclei, that permeate the Galaxy. As they traverse the interstellar medium, they encounter gas, dust and photon fields, ...

The international CTAO LST Collaboration has released remarkable findings from observations of GRB 221009A—the brightest gamma-ray burst (GRB) ever recorded. The results were published in The ...

Astronomers expanded this cosmic taxonomy in the 2010s by discovering superluminous supernovae. These rare explosions, sometimes called hypernovae, shine 100 times brighter than standard supernovae.

Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to create compact gamma-ray sources that are simultaneously brighter, sharper, ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

An X8.2 class solar flare flashes in the edge of the Sun on Sept. 10, 2017. This image was captured by NASA's Solar Dynamics Observatory and shows a blend of light from the 171 and 304 angstrom ...

A new result using NASA’s Chandra X-ray Observatory shows that the outer spiral arms in the Milky Way galaxy may reach wider ...

A bright band of diffuse gamma ray glow along the map's center, which marks the central plane of the Milky Way galaxy, is seen in an undated image based on five years of data from NASA's Fermi ...
