2 giant blobs in Earth’s mantle may explain Africa’s weird geology

Deep within Earth’s mantle, there are two giant blobs. One sits under Africa, while the other is almost precisely opposite the first, under the Pacific Ocean.

A Rare, Repeatedly Exploding Star Has Been Caught Producing Powerful Gamma Rays

A rare star that repeatedly explodes appears to be also generating the most energetic form of light in the Universe. Analysis of an eruption from the binary system RS Ophiuchi has revealed that the shock wave expanding out into space acts as a particle accelerator that generates gamma radiation. This suggests the conditions that generate … Read more
