Using microlensing, scientists have discovered a population of free-floating planets located beyond our own galaxy.
Amateur astronomers have discovered a new faint galaxy lurking in a known field.
Long-term X-ray observations of our closest neighboring star system, Alpha Centauri AB, reveal these stars’ flaring histories.
In August 2017, we detected gravitational waves from the collision of two neutron stars. What can observations from the months after the event tell us about the presence or absence of relativistic jets?
There are a lot of Sun-like stars in the universe. Are they as identical as the name suggests, or are there important differences between them?
Astrobites reports on how tidal forces between planets may be an important factor when considering tightly packed planetary systems like TRAPPIST-1.
This dramatic image reveals N49, the brightest supernova remnant in the Large Magellanic Cloud.
How we can better use computers to help us sift through the data to find transiting exoplanets?
How is energy released in explosive events like flares and jets? In a recent study, observations of the Sun provide us with a closer look.
Astrobites reports on the unusual pulsar J0537-6910, whose next glitch can be predicted to within a few days.
New observations from Hubble show signs of a Neptune-like exoplanet’s atmosphere being eroded away.
