"Unusual 'Blob' Emitting Intense Radiation Targets Earth in 76-Minute Intervals"

Scientists have discovered that regular bursts of high-energy gamma-ray radiation emanating from the supermassive black hole at the center of the Milky Way are coming from a spinning blob of gas around the black hole. The gamma-ray pulses occur approximately every 76.32 minutes and are related to periodic X-ray emissions from the same region. This finding suggests that the emissions are produced by a "blob" of gas swirling around the black hole at about one-third the speed of light. The discovery provides insights into the environment around supermassive black holes and could help scientists better understand similar phenomena in other galaxies.

The Sun: The Ultimate Particle Collider?

Astronomers have observed extremely high-energy particles coming out of the Sun even when it is relatively calm. The mystery has been solved by a team of theoretical astrophysicists who found that the chromosphere, the layer just below the photosphere, can have enough energy to accelerate cosmic rays to incredibly high energies. These particles then spit back out of the Sun and generate a flash of gamma ray radiation when they slam into a random proton near the surface of the Sun. This shows that the Sun is capable of accelerating particles to very high energies efficiently, even when there is nothing chaotic happening on the surface.
