Harvard-Smithsonian Center for Astrophysics 5 Sep 2019, 15:02 UTC Event Horizon Telescope Collaboration Director Shep Doeleman of the Center for Astrophysics | Harvard & Smithsonian will accept the 2020 Breakthrough Prize in Fundamental Physics on behalf of the EHT collaboration. The $3 million prize will be shared equally with the 348 scientists co-authoring any of the six papers published by the EHT on April 10, 2019.
NASA Breaking News 4 Sep 2019, 10:12 UTC NASA has selected three proposals for concept studies of missions that could help us better understand the dynamic space weather system driven by the Sun that manifests near Earth. The proposals examine what drives different parts of that system and ultimately could help us predict and mitigate its effects on spacecraft and astronauts, as NASA’s Artemis program looks to send the first woman and the next man to the Moon by 2024.
MIT 3 Sep 2019, 08:39 UTC Last December, scientists discovered an “active” asteroid within the asteroid belt, sandwiched between the orbits of Mars and Jupiter. The space rock, designated by astronomers as 6478 Gault, appeared to be leaving two trails of dust in its wake — active behavior that is associated with comets but rarely seen in asteroids.
ESA Top News 2 Sep 2019, 08:23 UTC Asteroid researchers and spacecraft engineers from the US, Europe and around the world will gather in Rome next week to discuss the latest progress in their common goal: an ambitious double-spacecraft mission to deflect an asteroid in space, to prove the technique as a viable method of planetary defence.
NASA's Goddard Space Flight Center 30 Aug 2019, 14:00 UTC This image from the NASA/ESA Hubble Space Telescope shows NGC 5307, a planetary nebula that lies about 10,000 light-years from Earth. It can be seen in the constellation Centaurus (the Centaur), which can be seen primarily in the southern hemisphere. A planetary nebula is the final stage of a Sun-like star. As such, planetary nebulas allow us a glimpse into the future of our own solar system. A star like our Sun will, at the end of its life, transform into a red giant. Stars are sustained by the nuclear fusion that occurs in their core, which creates energy. The nuclear fusion processes constantly try to rip the star apart. Only the gravity of the star prevents this from happening.

NCCR PlanetS 29 Aug 2019, 08:10 UTC A rocky extrasolar moon (exomoon) with bubbling lava may orbit a planet 550 light-years away from us. This is suggested by an international team of researchers led by the University of Bern on the basis of theoretical predictions matching observations. The “exo-Io” would appear to be an extreme version of Jupiter’s moon Io.Artist’s composition of a volcanic exo-Io undergoing extreme mass loss. The hidden exomoon is enshrouded in an irradiated gas cloud shining in bright orange-yellow, as would be seen with a sodium filter. Patches of sodium clouds are seen to trail the lunar orbit, possibly driven by the gas giant’s magnetosphere. (Illustration Thibaut Roger/University of Bern)Jupiter’s moon Io is the most volcanically active body in our solar system. Today, there are indications that an active moon outside our solar system, an exo-Io, could be hidden at the exoplanet system WASP-49b. “It would be a dangerous volcanic world with a molten surface of lava, a lunar version of close-in Super Earths like 55 Cancri-e” says Apurva Oza, postdoctoral fellow at the Physics Insitute of the University of Bern and associate of the NCCR PlanetS, “a place where Jedis go to die, perilously familiar to Anakin Skywalker.” But the object that ...
NASA's Jet Propulsion Laboratory News and Features 28 Aug 2019, 21:08 UTC Engineers attached NASA's Mars Helicopter, which will be the first aircraft to fly on another planet, to the belly of the Mars 2020 rover today in the High Bay 1 clean room at the Jet Propulsion Laboratory in Pasadena, California.
