National Radio Astronomy Observatory (NRAO) 17 Aug 2018, 15:00 UTC The ALMA telescope in Chile has transformed how we see the universe, showing us otherwise invisible parts of the cosmos. This array of incredibly precise antennas studies a comparatively high-frequency sliver of radio light: waves that range from a few tenths of a millimeter to several millimeters in length. Recently, scientists pushed ALMA to its limits, harnessing the array’s highest-frequency (shortest wavelength) capabilities, which peer into a part of the electromagnetic spectrum that straddles the line between infrared light and radio waves.
NASA's Jet Propulsion Laboratory News and Features 16 Aug 2018, 23:08 UTC NASA's Opportunity rover has been silent since June 10, when a planet-encircling dust storm cut off solar power for the nearly-15-year-old rover. Now that scientists think the global dust storm is "decaying" -- meaning more dust is falling out of the atmosphere than is being raised back into it -- skies might soon clear enough for the solar-powered rover to recharge and attempt to "phone home."
Harvard-Smithsonian Center for Astrophysics 16 Aug 2018, 21:07 UTC Astronomers from Durham University and the Harvard-Smithsonian Center for Astrophysics (CfA) have found evidence that the faintest satellite galaxies orbiting our own Milky Way galaxy are among the very first galaxies that formed in our Universe.
HubbleSite NewsCenter -- Latest News Releases 16 Aug 2018, 17:00 UTC Astronomers using the ultraviolet vision of NASA’s Hubble Space Telescope have captured one of the largest panoramic views of the fire and fury of star birth in the distant universe. The field features approximately 15,000 galaxies, about 12,000 of which are forming stars.
NCCR PlanetS 16 Aug 2018, 06:34 UTC Exoplanets, planets in other solar systems, can orbit very close to their host star. When, in addition to this, the host star is much hotter than our Sun, then the exoplanet becomes as hot as a star. The hottest “ultra-hot” planet was discovered last year by American astronomers. Now, an international team, led by researchers from the University of Geneva (UNIGE), who joined forces with theoreticians from the University of Bern (UNIBE), Switzerland, discovered the presence of iron and titanium vapours in the atmosphere of this planet. The detection of these heavy metals was made possible by the surface temperature of this planet, which reaches more than 4,000 degrees.
MIT 16 Aug 2018, 04:00 UTC MIT scientists have uncovered a sprawling new galaxy cluster hiding in plain sight. The cluster, which sits a mere 2.4 billion light years from Earth, is made up of hundreds of individual galaxies and surrounds an extremely active supermassive black hole, or quasar.
ESA Top News 14 Aug 2018, 14:55 UTC This image of three miniature satellites or CubeSats freshly launched into space is a striking reminder of human cooperation at the heart of space exploration. Bhutan’s first ever satellite along with others from Malaysia and the Philippines were released into their respective orbits from the International Space Station on 10 August.
