Hubble’s Vivid New Images of Jupiter’s Polar Aurora –“Larger than Earth”




Astronomers are using the NASA/ESA Hubble Space Telescope to study auroras — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the Solar System, Jupiter. This observation program is supported by measurements made by NASA’s Juno spacecraft, currently on its way to Jupiter. Jupiter’s auroras were first discovered by the Voyager 1 spacecraft in 1979. A thin ring of light on Jupiter’s nightside looked like a stretched-out version of our own auroras on Earth. Only later on was it discovered that the auroras were best visible using the ultraviolet capabilities of the NASA/ESA Hubble Space Telescope.


“Rogue Monsters of the Cosmos” –Supermassive Black Holes Detected Ejected from Their Galaxy





The central regions of many glittering galaxies, our own Milky Way included, harbor cores of impenetrable darkness — black holes with masses equivalent to millions, or even billions, of suns. What’s more, these supermassive black holes and their host galaxies appear to develop together, or “co-evolve.” Theory predicts that as galaxies collide and merge, growing ever more massive.


Scientists Shift Search for Alien Technological Civilizations to Ancient Red-Dwarf Stars –“Twice Age of Earth”





“Red dwarfs – the dim bulbs of the cosmos – have received scant attention by SETI scientists in the past,” SETI Institute engineer Jon Richard said last week in a news release announcing the initiative. “That’s because researchers made the seemingly reasonable assumption that other intelligent species would be on planets orbiting stars similar to the sun.”


First Alien Planet Discovered Photographed in 1917! (Today’s Most Popular)





Sorry NASA, but it turns out that a 1917 image on an astronomical glass plate from the Carnegie Institute Observatories’ collection shows the first-ever evidence of a planetary system beyond our own Sun. This unexpected find was recognized in the process of researching an article about planetary systems surrounding white dwarf stars in New Astronomy Reviews.


“Recycling the Hidden Universe” –Forging Cosmic Dust Into Stars




The Universe is becoming gradually cleaner as more and more cosmic dust is being mopped up by the formation of stars within galaxies, an international team of astronomers has revealed. Peering back 12 billion years using the Herschel space telescope to produce far-infrared images of the sky, the team led by researchers at Cardiff University has been able to observe the very early formation of galaxies and compare them to galaxies that have formed much more recently.
