The Giant Impact Hypothesis is the most widely accepted theory for the creation of the Moon; the authors here investigate possible configurations of the early Solar System to produce the right conditions for impact between Earth and the doomed proto-planet Theia.
How do the most massive stars explode? A new model of massive stars predicts new observational evidence.
Astronomical data gathered over time has gaps. Even the most reliable space telescopes suffer from occasional pauses in their otherwise constant watchfulness. Why are gaps a problem? Can’t astronomers just analyze the short chunks of data that don’t have gaps? The answer: Fourier transforms.
Many exoplanets in our galaxy are all alone. They have no one to cuddle up to on those cold, lonely nights in space…
In the next few years, gravitational wave detectors are expected to start finding mergers of compact objects. But their resolution is limited to large areas of the sky. Fast galaxy surveys are needed to aid in the task of locating the source more precisely, but how fast can they go?
There does not seem to be enough mass in protoplanetary disks to build the planetary systems we’ve detected. The solution: planet formation might start sooner than previously thought.
Y dwarfs are the coolest end of the stellar classification scheme, and studying these often cloudy objects comes with plenty of challenges.
Thought dust could only bore you? Think again: it may obscure our view of time’s very beginning!
Asteroids and volcanoes are familiar harbingers of global doom. But what about Gamma Ray Bursts? Is another doomsday lurking?
Spherical cows have a long and storied history in physics, but does this type of crude approximation lead to realistic conclusions in the case of star formation? The combination of large- and small- scale simulations tests this idea.
