For many years, most astrophysical models assumed that planets beyond our solar system, known as exoplanets, are heated at similar depths by their host stars (i.e., stars like the sun around which planetary systems are formed). ...
Astronomers have discovered a pair of exoplanets orbiting an M dwarf star, one of which is the coldest M dwarf planet found by the TESS satellite observatory, making it accessible for follow-up studies of its atmosphere. ...
On October 19, 2017, astronomers with the Pan-STARRS survey detected an interstellar object (ISO) passing through our solar system for the first time. The object, known as 1I/2017 U1 'Oumuamua, stimulated significant scientific ...

A team of astrophysicists and astronomers from Harbin Institute of Technology, Johns Hopkins University and Peking University has found evidence from Voyager 2 data showing that Jupiter has at least three magnetosheath jets. ...
When we look at the moon, either through a pair of binoculars, a telescope, or past footage from the Apollo missions, we see a landscape that's riddled with what appear to be massive sinkholes. But these "sinkholes" aren't ...
