'Dark force' theory could solve two open cosmic mysteries, reports Robert Lea for Space.com--Now there is an intriguing possibility that dark matter may be more complex and vibrant than we expected. "Its density is so high that it is extremely unlikely in the prevailing cold dark matter theory," Hai-Bo Yu, team leader and a professor of physics and astronomy at the University of California, Riverside, said in a statement. 

Lots of oxygen existed in ancient galaxies of the early Universe, reports Physics World. "Using a cutting-edge spectrograph on the James Webb Space Telescope (JWST), astronomers have found evidence that interstellar oxygen was far more abundant in many ancient galaxies than previously thought. Led by Kimihiko Nakajima at the National Astronomical Observatory of Japan, the team hopes that their observations could improve our understanding of the early universe."

Water ice crystals in Saturn’s ring system could be hiding evidence of aquatic alien life. The ice plumes were first confirmed by NASA’s Cassini spacecraft during the height of its mission. Cassini detected water jets exiting Enceladus at roughly 1,300 kilometers (800 miles) per hour, reports SyFy.com
