The Case of the Missing Giants
Red giant stars are bright enough to see at the center of our galaxy, but they are missing. A new study puts stars in a wind tunnel to explore a possible way to dim the lights.
The tempestuous adolescence of circumstellar disks
Massive gas inflow can trigger disks around young stars to become gravitationally unstable, resulting in vigorous accretion onto the star.
Creating a Cosmic Inventory of Rocky Planets
Combining cosmology, galaxy formation, and exoplanet science together, can we calculate the number of rocky planets in the entire universe?
Opening Our Ears to the Universe: LIGO Observes Gravitational Waves!
A century after Einstein’s prediction of gravitational waves, LIGO has observed these minuscule ripples in the fabric of spacetime. A new window to the Universe has opened.
Uncovering planets and stellar activity using only radial velocities
How do we model stellar activity to disentangle planet signals from stellar activity using only RVs?
Moon Zoo: Counting lunar craters with “citizen science”
Crowdsourcing provides a cheap and efficient way for astronomers to analyze features on the lunar surface.
