Its been a busy week, so I’m a bit late getting this compiled. I’ll try to get the geology news from Physical done shortly after this is posted.
- a tornado as big as the Earth went careening across the surface of the Sun for over 30 hours at the beginning of February — wow
- NASA released this week an image from Cassini of Rhea & Titan (Saturn’s 2 largest moons) lined up
- Hubble sees evidence for tellurium in several 12 billion year old stars
- residues of the explosion of Eta Carinae has been observed by the Las Cumbres Observatory Global Telescope Network — the explosion was first seen on Earth in the 1837 and recorded by a variety of cultures including aborigines
- new graben have been observed on the Moon that may indicate seismic activity less than 50 Myr old — this one was quite popular both on twitter & by my students
- using precise GPS measurements to test numerical models of the link between earthquakes and plate motions — result could be long-term, not short-term, earthquake forecasting
- Hubble images a new exo-planet that may have a large portion of its mass made up of water & has a thick water-rich atmosphere
