OSU and NASA to Search Milky Way for Rogue Planets

OSU researchers and study authors think during a new NASA mission they may find there are as many starts in the Milky Way as there are “rogue planets” which float in space without orbiting a sun.

The mission will provide a whole new viewpoint of what is out there in space. The researchers stated: imagine our rocky world floating freely in space, this is the kind of thing we hope to find.

Researchers hoped that NASA’s upcoming Nancy Grace Roman Space Telescope would find hundreds of these free-floating rogue planets in the Milky Way. By identifying and counting those rogue planets scientists think they can then extrapolate an estimate of how many there maybe in the galaxy.

Rogue, free-floating, planets are isolated objects Their masses are similar to a planet and the origin of objects is unknown. Some believe they used to have a host start that no longer exists.

Researchers said that the universe could be swarming with such objects and we don’t know it and that without the new NASA mission involving the microlensing survey the Roman Space Telescope is going to do they wouldn’t be able to complete their research.

 

OSU Team Helps Make Discovery About the Contents of the Universe

The Ohio State University and their colleagues from the Dark Energy Survey (DES) collaboration have reached a new milestone mapping the growth of the universe from its infancy to present day.

The new results released last Thursday confirm the surprisingly simple but puzzling theory that the present universe is comprised of only 4% ordinary matter, 26% mysterious dark matter, and the remaining 70% in the form of mysterious dark energy, which causes the accelerating expansion of the universe.

The findings are based on data collected during the DES first year, which covers over 1300 square degrees of the sky or about the area of 6,000 full moons. DES uses the Dark Energy Camera mounted on the Blanco 4m telescope at the Cerro Tololo Inter-American Observatory high in the Chilean Andes.

The new results from the Dark Energy Survey will be presented by Kavli fellow Elisabeth Krause at the TeV Particle Astrophysics Conference in Columbus, Ohio, on Aug. 9, and by CCAPP’s Troxel at the International Symposium on Lepton Photon Interactions at High Energies in Guanzhou, China, on Aug. 10.
