| Posted: 28 Jun 2021 02:05 PM PDT Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars. New findings suggest that Earth-sized worlds could be lurking undiscovered in binary star systems, hidden in the glare of their parent stars. As roughly half of all stars are in binary systems, this means that astronomers could be missing many Earth-sized worlds. |
| Unique exoplanet photobombs CHEOPS study of nearby star system Posted: 28 Jun 2021 02:05 PM PDT While studying two exoplanets in a bright nearby star system, the CHEOPS satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals exciting details about a rare planet 'with no known equivalent', as the scientific team points out. |
| Satellite unexpectedly detects a unique exoplanet Posted: 28 Jun 2021 12:29 PM PDT An exoplanet-hunting satellite has unexpectedly detected a third planet passing in front of its star while it was exploring two previously known planets around the same star.

| Posted: 28 Jun 2021 08:41 AM PDT Scientists have discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive. They are thought to arise from the explosions of massive super-asymptotic giant branch (SAGB) stars, for which there has also been scant evidence. |
