Cosmic Cannon; Mars Dust Storm Forecast; Dione’s Subsurface Ocean
Astronomers Find a Cosmic Cannon Astronomers have spotted super-hot blobs of plasma blasting into space like cannonballs near a dying red giant star, some 1,200 light years away. Using the Hubble Space Telescope to make their discovery, the scientists found that the balls of hot gas are flying so fast a trip from the Earth […]

Ultra-Dark Galaxies; Exoplanet With Comet-Like Tail; New Dinosaur Species
Astronomers Find Huge Treasure Trove of Ultra-Dark Galaxies U.S. and Japanese researchers have discovered 854 “ultra dark galaxies” located within the Coma Cluster, about 321 million light years from Earth. Dark galaxies are described as those that are totally composed of or are mostly filled with dark matter, which cannot be seen by telescopes. Nevertheless, […]
