Researchers may have discovered direct evidence of a former sister planet that resided in our Solar System, but was obliterated during an unknown cataclysm that occurred billions of years ago. It is theorized that the Solar System may have had as many as ten such lost planets early in its history, but this new evidence takes such theories and brings them that much closer to reality.

Astronomers have discovered something strange about an ultra-diffuse galaxy in the Coma Cluster called Dragonfly 44. It went largely overlooked by astronomers until recently, due to it only emitting 1 percent of the light that the Milky Way does, hence its "ultra diffuse" status. But Dragonfly 44 has recently been found to be nearly the same mass as our own galaxy, due to being made nearly entirely of dark matter.

A new and somewhat radical theory has been proposed by an international group of researchers, in that the center of the Milky Way galaxy might turn out to be a giant wormhole, with the mouth of the wormhole possibly spanning the breadth of the entire galaxy.

Astronomers have made some very interesting discoveries in space recently, each potentially bringing them one step closer to finding habitable exo-planets with signs of extra-terrestrial life-forms.
A study appearing this week in the journal Nature revealed findings extracted from the combined offerings of three NASA space telescopes: Hubble, Spitzer, and Kepler. Data from the telescopes showed clear skies and steamy water vapor on a gaseous planet outside our solar system.
