ESA Top News 22 May 2019, 08:00 UTC ESA’s Large Diameter Centrifuge at the Agency’s technical heart in the Netherlands is seen running here at full speed. The 8-m diameter four-arm centrifuge gives researchers access to a range of hypergravity environments up to 20 times Earth’s gravity for weeks or months at a time.
NASA's Jet Propulsion Laboratory News and Features 20 May 2019, 16:02 UTC NASA's Juno mission to Jupiter made the first definitive detection beyond our world of an internal magnetic field that changes over time, a phenomenon called secular variation. Juno determined the gas giant's secular variation is most likely driven by the planet's deep atmospheric winds.
ESA Top News 20 May 2019, 14:45 UTC Black holes are among the most fascinating objects in the Universe. Enclosing huge amounts of matter in relatively small regions, these compact objects have enormous densities that give rise to some of the strongest gravitational fields in the cosmos, so strong that nothing can escape – not even light.

ESA Space Science 16 May 2019, 09:00 UTC Mars was once believed to be criss-crossed by a system of irrigation canals – dark troughs that sliced across the planet’s surface, excavated by an intelligent society of thirsty martians. The astronomer who promoted this idea lends his name to the crater shown in this image from ESA’s Mars Express: Lowell crater.
NASA's Jet Propulsion Laboratory News and Features 15 May 2019, 19:21 UTC NASA's Mars Reconnaissance Orbiter hit a dizzying milestone this morning: It completed 60,000 loops around the Red Planet at 10:39 a.m. PDT (1:39 p.m. EDT). On average, MRO takes 112 minutes to circle Mars, whipping around at about 2 miles per second (3.4 kilometers per second).
NASA's Goddard Space Flight Center 15 May 2019, 14:54 UTC The photo above shows the landing site of the Israeli Beresheet spacecraft on a region of the Moon called Sea of Serenity, or Mare Serenitatis in Latin. On April 11, 2019,
Max Planck Institute for Astronomy 14 May 2019, 17:00 UTC One of the largest and most detailed simulations of the cosmos has released most of its data to the public, as described in an article that has just been published.
NASA's Goddard Space Flight Center 13 May 2019, 15:00 UTC The Moon is shrinking as its interior cools, getting more than about 150 feet (50 meters) skinnier over the last several hundred million years. Just as a grape wrinkles as it shrinks down to a raisin, the Moon gets wrinkles as it shrinks. Unlike the flexible skin on a grape, the Moon’s surface crust is brittle, so it breaks as the Moon shrinks, forming “thrust faults” where one section of crust is pushed up over a neighboring part.
ESA Space Science 13 May 2019, 13:00 UTC One has a thick poisonous atmosphere, one has hardly any atmosphere at all, and one is just right for life to flourish – but it wasn’t always that way. The atmospheres of our two neighbours Venus and Mars can teach us a lot about the past and future scenarios for our own planet.
