Can a star make planets with 10% of what the Sun had to work with? A synergy between two powerhouse survey telescopes is helping astronomers find that answer.
The exoplanet candidate, tentatively named Proxima c, would be a frozen snowball.
The online community of the Milky Way Project citizen scientists helped scientists identify compact star-forming regions now known as yellowballs.
Once thought to be part of the same population, planets larger than Jupiter and “failed stars” likely grow via different mechanisms, the Gemini Planet Imager Exoplanet Survey has shown.
In the most detailed and highest-resolution black hole simulation to date, an international team of researchers showed the Bardeen-Petterson effect for the first time.
Stars with giant planets tend to have a few key elements in abundance. A new algorithm used these patterns to predict hundreds of stars that will likely have exoplanets if we go looking for them.
The elongated tail of the SU Aurigae protoplanetary disk was likely formed as a result of a flyby from a substellar object.
Because of a new, surprisingly smaller mass estimate for a much-studied, nearby brown dwarf, astronomers now regard the familiar object as merely planetlike.
The newly discovered planet balances precariously in orbit within the star system, puzzling scientists.
Scientists searching for life in the universe now have a new target: the once-icy worlds orbiting red giants.
