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

NASA's Goddard Space Flight Center 14 May 2021, 13:45 UTC This image taken with the NASA/ESA Hubble Space Telescope showcases the emission nebula NGC 2313. Emission nebulae are bright, diffuse clouds of ionized gas that emit their own light.
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).

Universe Today 14 May 2021, 17:03 UTC A new report from the US Government Accountability Office (GAO) says that the launch of the long-awaited, highly anticipated James Webb Space Telescope (JWST) will very likely be delayed due to an anomaly identified in the Ariane 5 launch vehicle. Launch for JWST is currently scheduled for October 31, 2021, but that date could slip by at least a couple of weeks.
Centauri Dreams 14 May 2021, 10:32 UTC Is there any chance we may one day find technosignatures around the nearest stars? If we were to detect such, on a planet, say, orbiting Alpha Centauri B, that would seem to indicate that civilizations are to be found around a high percentage of G- and K-class stars. Brian Lacki (UC-Berkeley) examined the question from all angles at the recent Breakthrough Discuss, raising some interesting issues about the implications of technosignatures, and the assumptions we bring to the search for them.
Parabolic Arc 14 May 2021, 03:07 UTC By January, we can expect to see paying customers on three American and Russian flights to the International Space Station (ISS), one Crew Dragon mission in Earth orbit, and two or more suborbital flights.
Extrasolar Object Interceptor Would be Able to Chase Down the Next Oumuamua or Borisov and Actually Return a Sample13 May 2021, 18:21 UTC What if we had the ability to chase down interstellar objects passing through our Solar System, like Oumuamua or Comet Borisov? Such a spacecraft would need to be ready to go at a moment’s notice, with the capacity to increase speed and change direction quickly. That’s the idea behind a new mission concept called the Extrasolar Object Interceptor and Sample Return spacecraft.
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.
