The study challenges sciences current understanding of how massive galaxies form and evolve early in the history of the universe. *New dark matter hypothesis Astronomers trying to understand dark matter may have a lot more work to do if a new hypothesis -- claiming there is more than one type of dark matter particle – is correct. Dark matter is a mysterious invisible substance thought to make up some 80 percent of all the matter in the universe. *How the Milky Way Galaxy makes antimatter Faint supernova explosions -- caused by the merging of dead stars known as white dwarfs -- could explain how most of the antimatter in the Milky Way galaxy is created. The findings also mean the excess of gamma ray emissions detected in the galactic centre can be explained without the need to postulate dark matter annihilation scenarios to explain the observations. *New mission to study the space between the stars NASA is today slated to launch its newest mission to study the interstellar medium -- the space between the stars. NASA’s new mission called the Colorado High-resolution Echelle Stellar Spectrograph -- or CHESS – is slated to blast off from the White Sands Missile Range in New Mexico aboard a Black Brant IX suborbital sounding rocket. *China launches its first space based x-ray telescope China has launched its first space based X-ray telescope designed to survey the Milky Way and study celestial x-ray sources such as neutron stars, black holes and supernovae. The Hard X-ray Modulation Telescope was flown into orbit aboard a Long March 4B rocket from the Jiuquan Satellite Launch Centre in the Gobi Desert of inner Mongolia. Email: [email protected] Join our mailing list at http://www.bitesz.com/join-our-mailing-list If you're enjoying SpaceTime, please help out by sharing and telling your friends.
