9 Apr 2021, 19:56 UTC So, you want to find dark matter, but you don’t know where to look? A giant planet might be exactly the kind of particle detector you need! Luckily, our solar system just happens to have a couple of them available, and the biggest and closest is Jupiter. Researchers Rebecca Leane (Stanford) and Tim Linden (Stockholm) released a paper this week describing how the gas giant just might hold the key to finding the elusive dark matter. Next Previous

American Astronomical Society 11 May 2021, 16:25 UTC NASA’s newest Mars rover is beginning to study the floor of an ancient crater that once held a lake.
NASA's Goddard Space Flight Center 10 May 2021, 19:22 UTC After nearly five years in space, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft is on its way back to Earth with an abundance of rocks and dust from the near-Earth asteroid Bennu.
ESA Top News 6 May 2021, 08:00 UTC The Jupiter Icy Moons Explorer, Juice, has come ‘home’ to ESA’s technical centre in the Netherlands to undergo an extreme environment test in Europe’s largest thermal vacuum chamber to prepare for its journey to the outer Solar System.
NASA Breaking News 5 May 2021, 20:51 UTC The world’s largest and most powerful space telescope, Webb opened its iconic primary mirror wings in May as part of the telescope’s final testing regimen at Northrop Grumman in Redondo Beach, California. The conclusion of this test represents an important milestone as Webb marches toward launch.
NASA's Goddard Space Flight Center 30 Apr 2021, 13:00 UTC The interaction of two doomed stars has created this spectacular ring adorned with bright clumps of gas – a diamond necklace of cosmic proportions. Fittingly known as the “Necklace Nebula,” this planetary nebula is located 15,000 light-years away from Earth in the small, dim constellation of Sagitta (the Arrow).
Universities Space Research Association 23 Apr 2021, 14:19 UTC After making numerous discoveries of how magnetic fields shape our universe, an instrument flying on board the Stratospheric Observatory for Infrared Astronomy is about to get even faster at gathering data.

Universe Today 13 May 2021, 13:32 UTC The Gaia spacecraft is an impressive feat of engineering. Its primary mission is to map the position and motion of more than a billion stars in our galaxy, creating the most comprehensive map of the Milky Way thus far. Gaia collects such a large amount of precision data that it can make discoveries well beyond its main mission. For example, by looking at the spectra of stars, astronomers can measure the mass of individual stars to within 25% accuracy. From the motion of stars, astronomers can measure the distribution of dark matter in the Milky Way. Gaia can also discover exoplanets when they pass in front of a star. But one of the more surprising uses is that Gaia could help us detect cosmic gravitational waves.
Universe Today 12 May 2021, 20:10 UTC Within the Milky Way, there are an estimated 200 to 400 billion stars, all of which orbit around the center of our galaxy in a coordinated cosmic dance. As they orbit, stars in the galactic disk (where our Sun is located) periodically shuffle about and get closer to one another. At times, this can have a drastic effect on the star that experience a close encounter, disrupting their systems and causing planets to be ejected.
Physics World Blog 12 May 2021, 18:19 UTC Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general theory of relativity to the test – and the 106 year old theory has passed with flying colours.
Centauri Dreams 12 May 2021, 15:26 UTC What are the long-lasting waves detected by Voyager 1? Our first working interstellar probe — admittedly never designed for that task — is operating beyond the heliosphere, which it exited back in 2012. A paper just published in Nature Astronomy explores what’s going in interstellar space just beyond, but still affected by, the heliosphere’s passage through the Local Interstellar Medium (LISM).

NASA Space Station Blog 11 May 2021, 20:18 UTC Human research took precedence aboard the International Space Station on Tuesday as the Expedition 65 crew explored how weightlessness affects the immune system. The orbital residents also trained for a medical emergency and ensured station systems continued operating in tip-top shape.
