Bad Astronomy 22 Jul 2020, 13:00 UTC For a while now evidence has been mounting that Venus is currently geologically active. For example, the volcano Idunn Mons has a peak that's hotter than its surroundings, implying there may be magma inside it. There may be recent lava flows on the surface, and several hot spots have been detected, too.

Universe Today 21 Jul 2020, 16:47 UTC What happens when a giant planet gets stripped of its atmosphere? It leaves behind a giant core, rich in iron and other metals. A team using NASA’s TESS mission recently found such a remnant core, orbiting a star just 730 light-years away.
Starts With a Bang! 21 Jul 2020, 14:01 UTC It wasn’t supposed to be this way. Neutrinos, these tiny, ghostly, elusive but fundamental particles, weren’t supposed to have mass. According to the Standard Model of elementary particles, we should have three types of neutrino (electron, muon and tau) and three types of antineutrino, and they should be stable and unchanging in their properties once they’re created.
New Scientist 20 Jul 2020, 16:00 UTC Several dozen active volcanic sites have been identified on Venus for the first time. The discovery may aid future missions to the planet and add to our understanding of why there is life on Earth, but not Venus.
