Cosmic Rays from Massive Star System

Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is accelerating particles to high energies, some of which may reach the earth as cosmic rays.

Eta Carinae, located about 7,500 light-years away in the southern constellation of Carina, is famous for a 19th century outburst that briefly made it the second-brightest star in the sky.

Saturn's Moon Enceladus

Scientists have found complex carbon-based molecules in the waters of Saturn's moon Enceladus.

Compounds like this have only previously been found on Earth, and in some meteorites.

They are thought to have formed in reactions between water and warm rock at the base of the moon's subsurface ocean.

Though not a sign of life, their presence suggests Enceladus could play host to living organisms.
