• Mission to Jupiter's icy moon confirmed
  (Thu, 22 Aug 2019 14:32:18 EDT)
  
  An icy ocean world in our solar system that could tell us more about the potential for life on other worlds is coming into focus with confirmation of the Europa Clipper mission's next phase.
  
  
• Storms on Jupiter are disturbing the planet's colorful belts
  (Thu, 22 Aug 2019 13:04:38 EDT)
  
  Coordinated observations of Jupiter in early 2017 by six ground-based telescopes and Hubble allowed astronomers to study the evolution of bright plumes and connect them with cloud movements deep in the planet. They show that these plumes originate 80 kilometers below the surface cloud deck and rise up quickly into the stratosphere, where supercooled ammonia freezes to form ammonia ice clouds. The plumes create disturbances in the belts and even change their color.
  
  
• Maximum mass of lightest neutrino revealed using astronomical big data
  (Thu, 22 Aug 2019 11:34:07 EDT)
  
  The mass of the lightest neutrino, an abundant 'ghost' particle found throughout the universe, has been calculated to be at least 6 million times lighter than the mass of an electron.
  
  
• Temperatures of 800 billion degrees in the cosmic kitchen
  (Thu, 22 Aug 2019 10:14:19 EDT)
  
  It is among the most spectacular events in the universe: a merger of neutron stars. Astronomers have completed the first laboratory measurements of thermal electromagnetic radiation arising in such collisions. The resulting data enabled them to calculate the prevailing temperature when such stars merge.
  
  
• Spaceflight consistently affects the gut
  (Wed, 21 Aug 2019 12:05:51 EDT)
  
  A new study discovered that spaceflight -- both aboard a space shuttle or the International Space Station (ISS) -- has a consistent effect on the gut microbiome.
  
  
• Enabling longer space missions
  (Tue, 20 Aug 2019 13:09:36 EDT)
  
  The Hall thruster is a propulsion system that is often used by spacecraft engaged in longer missions. A recent study has shown how the operating lives of these systems can be further extended.
  
  
• Stardust in the Antarctic snow
  (Tue, 20 Aug 2019 10:16:23 EDT)
  
  The rare isotope iron-60 is created in massive stellar explosions. Only a very small amount of this isotope reaches the earth from distant stars. Now, a research team has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope comes from the interstellar neighborhood.
  
  
• Black hole holograms
  (Tue, 20 Aug 2019 10:16:06 EDT)
  
  Researchers show how a holographic tabletop experiment can be used to simulate the physics of a black hole. This work may lead the way to a more complete theory of quantum gravity that harmonizes quantum mechanics and relativity.
  
  
• A second planet in the Beta Pictoris system
  (Mon, 19 Aug 2019 11:27:35 EDT)
  
  A team of astronomers has discovered a second giant planet in orbit around alpha Pictoris, a star that is relatively young (23 million years old) and close (63.4 light years), and surrounded by a disk of dust. The alpha Pictoris system has fascinated astronomers for the last 30 years since it enables them to observe a planetary system in the process of forming around its star.
  
  
• Best of both worlds: Asteroids and massive mergers
  (Fri, 16 Aug 2019 09:24:27 EDT)
  
  Researchers are using the Catalina Sky Survey's near-Earth object telescopes to locate the optical counterparts to gravitational waves triggered by massive mergers.
  
  
• Moon glows brighter than sun in images from NASA's Fermi
  (Thu, 15 Aug 2019 12:06:56 EDT)
  
  If our eyes could see gamma rays, the Moon would appear brighter than the Sun! That's how NASA's Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade.
  
  
• Young Jupiter was smacked head-on by massive newborn planet
  (Thu, 15 Aug 2019 11:37:35 EDT)
  
  A colossal, head-on collision between Jupiter and a still-forming planet in the early solar system, about 4.5 billion years ago, could explain surprising readings from NASA's Juno spacecraft, according to a new study.
