ESA Science & Technology 24 Jun 2019, 15:00 UTC According to Liyi Gu, an astronomer from RIKEN High Energy Astrophysics Laboratory in Japan and the Netherlands Institute for Space Research, who is the lead author of a paper published today in Nature Astronomy, the observations capture the unique moment when the two clusters touch each other for the very first time – something that has never been observed before.
NASA's Jet Propulsion Laboratory News and Features 23 Jun 2019, 19:06 UTC This week, NASA's Curiosity Mars rover found a surprising result: the largest amount of methane ever measured during the mission - about 21 parts per billion units by volume (ppbv). It's exciting because microbial life is an important source of methane on Earth, but methane can also be created through interactions between rocks and water.

NASA's Goddard Space Flight Center 21 Jun 2019, 11:51 UTC This image shows an irregular galaxy named IC 10, a member of the Local Group — a collection of over 50 galaxies in our cosmic neighborhood that includes the Milky Way.
ESA Top News 20 Jun 2019, 22:19 UTC An Ariane 5 has delivered the T-16 and Eutelsat-7C telecom satellites into their planned orbits. Arianespace announced liftoff at 21:43 GMT (23:43 CEST, 18:43 local time) yesterday from Europe’s Spaceport in Kourou, French Guiana. The mission lasted about 33 minutes.
National Radio Astronomy Observatory (NRAO) 20 Jun 2019, 16:00 UTC Summary: Using the both ALMA and the VLT, astronomers have imaged the cold, rock-strewn rings encircling the planet Uranus. Rather than observing the reflected sunlight from these rings, ALMA and the VLT imaged the millimeter and mid-infrared “glow” naturally emitted by the frigidly cold particles of the rings themselves.The rings of Uranus are invisible to all but the largest telescopes — they weren’t even discovered until 1977 — and they stand out as surprisingly bright in new thermal images of the planet taken by two large telescopes in Chile.The thermal glow gives astronomers another window onto the rings, which have been seen only because they reflect a little light in the visible, or optical, range and in the near-infrared. The new images taken by the Atacama Large Millimeter/submillimeter Array (ALMA)Atacama Large Millimeter/submillimeter Array (ALMA)Funded by the U.S. National Science Foundation and its international partners (NRAO/ESO/NAOJ), ALMA is among the most complex and powerful astronomical observatories on Earth or in space. The telescope is an array of 66 high-precision dish antennas in northern Chile. See more here and the Very Large Telescope (VLT) allowed the team for the first time to measure the temperature of the rings: a cool 77 Kelvin, ...
NASA's Ames Research Center News and Features 19 Jun 2019, 15:58 UTC "I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." When President John F. Kennedy declared this to Congress in May 1961, humans had barely brushed past the outer edge of Earth’s atmosphere. Only a month earlier, the Soviet Union sent the first human to space, while America’s furthest foray at that time was Alan Shephard’s 15-minute flight that fell short of entering Earth’s orbit. Between that history-making speech and Neil Armstrong’s first step on the lunar surface in 1969 is the story of how NASA ensured our voyage to the Moon had a way to get back home.
ESA Top News 19 Jun 2019, 13:20 UTC ‘Comet Interceptor’ has been selected as ESA’s new fast-class mission in its Cosmic Vision Programme. Comprising three spacecraft, it will be the first to visit a truly pristine comet or other interstellar object that is only just starting its journey into the inner Solar System.
NASA's Chandra X-ray Observatory 18 Jun 2019, 18:20 UTC We have seen intricate patterns that milk makes in coffee and much smoother ones that honey makes when stirred with a spoon. Which of these cases best describes the behavior of the hot gas in galaxy clusters? By answering this question, a new study using NASA's Chandra X-ray Observatory has deepened our understanding of galaxy clusters, the largest structures in the Universe held together by gravity.
