Gemini Observatory 31 May 2018, 19:40 UTC A new study using Gemini data reveals that the ratio of binary stars in Kepler’s K2 exoplanet host stars is similar to that found elsewhere in our neighborhood of the Milky Way. According to lead author Dr. Rachel Matson of NASA’s Ames Research Center, “While we have known that about 50% of all stars are binary, to confirm a similar ratio in exoplanet host stars helps set some important constraints on the formation of potential exoplanets seen by Kepler.”
NASA's Jet Propulsion Laboratory News and Features 31 May 2018, 17:45 UTC NASA's Dawn spacecraft is maneuvering to its lowest-ever orbit for a close-up examination of the inner solar system's only dwarf planet.
NASA's Chandra X-ray Observatory 31 May 2018, 17:00 UTC The spectacular merger of two neutron stars that generated gravitational waves announced last fall likely did something else: birthed a black hole.
Hubble Space Telescope News 31 May 2018, 14:00 UTC Though it resembles a peaceful rose swirling in the darkness of the cosmos, NGC 3256 is actually the site of a violent clash. This distorted galaxy is the relic of a collision between two spiral galaxies, estimated to have occurred 500 million years ago. Today it is still reeling in the aftermath of this event.
ESA Top News 31 May 2018, 08:55 UTC In 2022, NASA’s Double Asteroid Redirection Test (DART) collides with the smaller body of the Didymos binary asteroid system in an attempt to measurably shift its orbit. ESA’s Hera mission, now under study, will examine the aftermath of this impact to help determine whether humans can deflect threatening asteroids.
Harvard-Smithsonian Center for Astrophysics 30 May 2018, 17:06 UTC Astronomers have proposed a new model for the invisible material that makes up most of the matter in the Universe. They have studied whether a fraction of dark matter particles may have a tiny electrical charge.
German Aerospace Center (DLR) 30 May 2018, 12:00 UTC When Alexander Gerst, Germany's European Space Agency (ESA) astronaut, sets off for the ISS on 6 June 2018 to spend his second six months in a microgravity environment he will be working on the largest international technology project of all time. The experiments are designed as contributions to solutions for global societal challenges such as health, the environment and climate change, as well as digitalisation, Industry 4.0, energy and future mobility.
ESO Top News 30 May 2018, 10:00 UTC Glowing brightly about 160 000 light-years away, the Tarantula Nebula is the most spectacular feature of the Large Magellanic Cloud, a satellite galaxy to our Milky Way. The VLT Survey Telescope at ESO’s Paranal Observatory in Chile has imaged this region and its rich surroundings in exquisite detail. It reveals a cosmic landscape of star clusters, glowing gas clouds and the scattered remains of supernova explosions. This is the sharpest image ever of this entire field.
NASA Breaking News 29 May 2018, 20:00 UTC NASA will host a media briefing at 1 p.m. EDT Monday, June 4, on the agency’s mission to explore Earth’s ionosphere and the processes there that impact life on Earth’s surface. The event will air live on NASA Television, the agency’s website and Facebook Live. Ionospheric Connection Explorer (ICON) will study the layer of charged particles extending from about 50 to 360 miles above Earth’s surface, through which radio communications and GPS signals travel, and the processes there that can distort or even disrupt these signals. Knowledge gleaned from this mission will aid in mitigating its effects on satellites and communications technology worldwide
