NASA Team Finds Noxious Ice Cloud on Saturn's Moon Titan Researchers with NASA's Cassini mission found evidence of a toxic hybrid ice in a wispy cloud high above the south pole of Saturn's largest moon, Titan. The finding is a new demonstration of the complex chemistry occurring in Titan's atmosphere-in this case, cloud formation in the giant moon's stratosphere-and part of a collection of processes that ultimately helps deliver a smorgasbord of organic molecules to Titan's surface. Inv...

ESO's fleet of telescopes in Chile have detected the first visible counterpart to a gravitational wave source. These historic observations suggest that this unique object is the result of the merger of two neutron stars. The cataclysmic aftermaths of this kind of merger - long-predicted events called kilonovae - disperse heavy elements such as gold and platinum throughout the Universe. This discovery, published in several papers in the journal Nature and elsewhere, also provides the strongest ev...

For the first time, NASA scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra. Shortly after 8:41 a.m. EDT on Aug. 17, NASA's Fermi Gamma-ray Space Telescope picked up a pulse of high-energy light from a powerful explosion, which was immediately reported to astronomers around the globe as a short gamma-ray burst. The scientists at the National S...

The first full-scale model of the rocket motor that will propel Ariane 6 and Vega-C into orbit has been cast and filled with inert propellant for testing at Europe's Spaceport in French Guiana. The P120C is the largest solid-propellant rocket motor ever built in one segment. Each P120C will hold over 140 tonnes of propellant in a carbon fibre casing almost 11.5 m long and about 3.4 m in diameter. It is derived from Vega's current first stage motor, the P80, which holds 88 tonnes of propell...

There's no map showing all the billions of exoplanets hiding in our galaxy -- they're so distant and faint compared to their stars, it's hard to find them. Now, astronomers hunting for new worlds have established a possible signpost for giant exoplanets. A new study finds that giant exoplanets that orbit far from their stars are more likely to be found around young stars that have a disk of dust and debris than those without disks. The study, published in The Astronomical Journal, focused on ...

Astronomers have identified a bumper crop of dual supermassive black holes in the centers of galaxies. This discovery could help astronomers better understand how giant black holes grow and how they may produce the strongest gravitational wave signals in the Universe. The new evidence reveals five pairs of supermassive black holes, each containing millions of times the mass of the Sun. These black hole couples formed when two galaxies collided and merged with each other, forcing their superma...
