An artist’s impression of a rogue planet detected in the Rho Ophiuchi region where infrared and other imaging helped uncover at least 70 of these objects. These free-floating planets have masses comparable to those of the planets in our solar system but do not orbit a star, instead roaming freely on their own. (European Southern Observatory/M. Kornmesser)

Lost In Space: Astronomers Find Evidence Of Dozens Of Free-Floating Rogue Planets

Evidence is mounting that rogue planets were ejected by their solar systems to wander in the dark.

The IAU in 2006 withdrew recognition of Pluto as a planet based on the current definition that a planet must clear its own orbit, but now researchers are pushing back, saying that definition is based on astrology, not science. This enhanced color image of Pluto was produced by combining four images from New Horizons Long Range Reconnaissance Imager with color data from the spacecraft Ralph instrument.

U.S. Army astronaut Drew Morgan exercises in space. According to a new study, microgravity causes more errors in DNA replication, which will lead to premature aging and other negative health effects for astronauts. (U.S. Army/Zenger)

Space Aged: Astronauts Age Faster Because Of Microgravity, Says Study

Weightlessness makes DNA replication more prone to errors, so astronauts experience the symptoms of aging earlier than normal.
