Estimating the number of intelligent civilizations from planet formation rates
By combining galaxy formation histories and planet formation models, we can estimate the number of potential civilizations in our Universe.
The Rocky Road to Gas Planet-hood
Why do some planets slightly more massive than Earth have gas envelopes, while others don’t?
Flinging Asteroids into the Habitable Zone
Planets in binary star systems can receive a sizable amount of water from asteroids getting perturbed out of their orbits
A long-awaited discovery
More than 50 years ago, a Norwegian astronomer named Sjur Refsdal outlined an interesting new method for calculating the Hubble constant. Last November, astronomers found the perfect test case.
Detonating white dwarfs with black holes
Dark matter, in the form of primordial black holes, can potentially trigger Type Ia supernovae in white dwarfs.
A Turbulent Law of Star Formation
Molecular clouds are turbulent. Today’s paper explores how this fact affects the relationship between star formation rate and density from local clouds to distant galaxies.
