Binary Stars May be Likely to Harbor Life, After All

Binary stars may be more likely to harbor life than once believed. Astronomers thought, until now, that life was unlikely to form in systems containing two or more stars. However, a new computer model developed by an undergraduate student of astronomy shows that as binary stars form in stellar nurseries, they are often passed by a third sun. Gravity from this passer-by can draw the two binary stars closer together, increasing the amount of area warm enough for liquid water to pool on planets. Water is necessary for life on Earth to exist, and planets with water are thought to be more likely to harbor life.

Weird Exoplanet Discovered by TESS Spacecraft – Strange World, Indeed!

A strange exoplanet sitting 53 light years from Earth has been discovered by astronomers using the TESS spacecraft. This world is three times larger than the Earth, but 23 times as dense. This suggests it is likely surrounded by a thick atmosphere, denser than that seen on Uranus or Neptune. The planet, HD 2172b, speeds around its parent star once every 36 days. This is the third confirmed planet found by TESS, although astronomers are looking through data showing more than 280 other potential worlds.
