ESA Top News 8 Aug 2019, 09:00 UTC This image from ESA’s Mars Express shows Terra Cimmeria, a region found in the southern highlands of Mars. It comprises data gathered on 11 December 2018 during Mars Express Orbit 18904. The ground resolution is approximately 13 metres per pixel and the images are centred at about 171° East and 40° South. This image was created using data from the nadir and colour channels of the High Resolution Stereo Camera (HRSC). The nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface. North is to the right.
National Radio Astronomy Observatory (NRAO) 7 Aug 2019, 15:00 UTC What happens inside a black hole stays inside a black hole, but what happens inside a black hole’s “sphere of influence” – the innermost region of a galaxy where a black hole’s gravity is the dominant force – is of intense interest to astronomers and can help determine the mass of a black hole as well as its impact on its galactic neighborhood.
MIT 7 Aug 2019, 03:59 UTC Vast interstellar events where clouds of charged matter hurtle into each other and spew out high-energy particles have now been reproduced in the lab with high fidelity. The work, by MIT researchers and an international team of colleagues, should help resolve longstanding disputes over exactly what takes place in these gigantic shocks.
NASA Glenn Research Center 6 Aug 2019, 12:03 UTC NASA is building a system to send astronauts to the Moon for Artemis missions, and that includes tests to make sure the Orion spacecraft is prepared to safely carry crew on an alternate mission profile in the face of unexpected problems. That capability was most recently demonstrated with a successful, continuous 12-minute firing of Orion's propulsion system that simulated a possible alternate mission scenario.
ESA Top News 5 Aug 2019, 10:30 UTC This image shows a snippet of the Sun up close, revealing a golden surface marked by a number of dark, blotchy sunspots, curving filaments, and lighter patches known as ‘plages’ – brighter regions often found near sunspots. The width of the image would cover roughly a third of the diameter of the solar disc.
ESA Top News 2 Aug 2019, 08:18 UTC On 25 July, an asteroid the size of a football field flew by Earth, coming within 65 000 km of our planet’s surface during its closest approach – about one fifth of the distance to the Moon. The 100 m-wide asteroid dubbed '2019 OK' was detected just days before it passed Earth, although archival records from sky surveys show it had previously been observed but wasn't recognised as a near-Earth asteroid.
