Does the Galactic Bulge Have Fewer Planets?
The Milky Way’s dense central bulge is a very different environment than the galactic disk. Do the differences affect the ability of planets to form there?
Matching Supernovae to Galaxies
A major challenge for modern supernova surveys is identifying the galaxy that hosted each explosion. Is there an accurate and efficient way to do this that avoids investing significant human resources?
X-Ray Background from Early Binaries
What impact did X-rays from the first binary star systems have on the universe around them? A new study suggests this radiation may have played an important role during the reionization of our universe.
Hunting for Cosmic-Ray Origins with SuperTIGER
The SuperTIGER experiment flew over Antarctica for 55 days, collecting millions of galactic cosmic rays. What can it tell us about the origins of these high-energy particles?
An Exoplanet Spinning Up Its Star
A recently discovered, unusual hot Jupiter may be causing its star to spin faster than it should.
Using LISA to Learn How Pairs of Black Holes Formed
How are black-hole binaries built? Upcoming observations of gravitational waves from these systems may be able to reveal their origins.
Could Ultracool Dwarfs Have Sun-Like Activity?
Sun-like stars have magnetic cycles that regulate their flares, starspots, and other activity. But what about stars much cooler and smaller than the Sun?
A Pulsar and White Dwarf in an Unexpected Orbit
The eccentric orbit of a low-mass white dwarf around a millisecond pulsar defies expectations of how binaries like this form.
Flying Through Dust From Asteroids
What if we could learn more about an asteroid near Earth without needing to land on it? We can — by flying through its dust!
