Earth May Have Created Its Own Water Deep Within; And There's Still Enough There To Fill The Pacific


A new study suggests the Earth may have made its own water deep within its crust, as well as receiving the vital substance from extraterrestrial objects such as icy comets.

A team of researchers revealed evidence of an unknown geochemical pathway used by the Earth to sequester water deep within, releasing small amounts through plate tectonics in a process that feeds our oceans "from within," Ohio State University reported.

Past theories about the Earth's early days suggest it was dry and inhospitable to life until it was pummeled by icy comets, which deposited water onto the surface; these new findings provide an alternative idea.

Hubble Spots Progenitor of a Rare Type of Supernova



Using data from observations made in the last two decades using the Hubble Space Telescope researchers say they have spotted ‘zombie stars.’ The study is described in the journal Nature.

After a supernova, the star is completely destroyed and the materials scattered in space. However there are weaker explosions known as Type Iax whereby the remnants of the explosion find new life. The zombie which created the supernova has been named SN 212 Z.

The researchers say two stars initially existed, a large one and a companion which as smaller. Hydrogen left the larger star for the smaller one. With time the smaller one grew in size and engulfed the larger one. The larger one became a white dwarf. A weaker explosion eroded the outer layers of the initially small star leaving behind a helium core and the white dwarf.
