New Glossary: Guide to Major Telescopes
Check out our newest glossary describing the ground-based and space-based observatories used by astronomers.
Astrobiology: Seeking Out the Origin of Life, New Life, and New Civilizations
Sukrit and I just got back from the Saas-Fee astrobiology course. We learned about deep-sea life, the evolution of Earth’s atmosphere, the search for life on Titan, and more.
Fireflies in Starlight: Looking for Planets in the Sirius System
Is there a third companion in the Sirius system? Thalmann et al. conduct direct imaging observations to find out.
Are Stars with Planets More Active?
Do close-in planets cause their host stars to become more magnetically active? Canto Martins et al. compare stars with and without planets to address this question.
Detecting Transiting Planets Around White Dwarfs
The Kepler mission is doing a fantastic job detecting planets around main sequence stars, but what about white dwarfs? Do they have planets? If they do, Agol 2011 suggests that those planets could be detected in ground-based transit surveys.
