Ceres’ Transient Exosphere is Product of Solar Activity, Planetary Researchers Say
Planetary researchers have long thought that the dwarf planet Ceres may have a temporary, thin atmosphere (an exosphere), but mysteries lingered about its origin and why it’s not always present. Now, scientists from NASA’s Dawn mission suggest that the Cerean exosphere appears to be related to the behavior of the Sun, rather than Ceres’ proximity [...]
Evolution of Long Term Variability in Solar Analogs
Earth is the only planet known to harbor life, therefore we may speculate on how the nature of the Sun-Earth interaction is relevant to life on Earth, and how the behavior of other stars may influence the development of life...
NASA to Reveal New Discoveries in News Conference on Oceans Beyond Earth
NASA will discuss new results about ocean worlds in our solar system from the agency’s Cassini spacecraft and the Hubble Space Telescope during a news briefing 2 p.m. EDT on Thursday, April 13.
Long ago and far away, an average galaxy: 'Typical' galaxy helps astronomers study epoch of reionization
Using a giant galaxy cluster as a cosmic-scale lens, astronomers have discovered a galaxy from the early universe that they think is 'typical' of its time. This could help astronomers better understand the Epoch of Reionization when the first galaxies appeared.
Hubble spots auroras on Uranus
A composite image of Uranus by Voyager 2 and two different observations made by Hubble shows one for the ring and one for the auroras found around the planet.
Expedition 50 had a fun and good ISS crew
I believe Expedition 50 had a fun and good ISS crew. I base this declaration solely on the moments they shared on social media. This logic is completely bulletproof and there's no point trying to prove otherwise.
Cosmonaut Georgy Grechko, Launched to Salyut Space Stations, Dies at 85
Soviet-era cosmonaut Georgy Grechko, who in 1977 performed the first spacewalk using a Russian spacesuit design still in use today on the International Space Station, has died. He was 85. Grechko flew on three missions to Russia's Salyut space stations.

Astronomers Detect Atmosphere around Super-Earth GJ 1132b
An international team of astronomers, led by Keele University researcher John Southworth, has managed to detect an atmosphere around GJ 1132b, a ‘super-Earth’ exoplanet in the constellation Vela, 39.3 light-years from us. GJ 1132b (Gliese 1132b) orbits the red dwarf star GJ 1132, which is only 1/5 the size of our Sun and is cooler [...]
