A NASA spacecraft set to explore a metallic asteroid for the first time will launch in 2022, a year earlier than originally planned, and reach its destination in 2026, four years ahead of schedule, giving ground teams a shorter wait for the mission's scientific payoff and shaving $100 million off the project's total cost, officials said…

Astronomers have watched as N6946-BH1, a red supergiant with a mass of 25 solar masses in the spiral galaxy NGC 6946, was likely reborn as a black hole. N6946-BH1 should have exploded in a bright supernova. Instead, it fizzled out — and then left behind a black hole. “Massive ‘fails’ like this one in a [...]…

A team of chemists at the Van ‘t Hoff Institute for Molecular Sciences of the University of Amsterdam, the Netherlands, has designed and synthesized a new class of molecules: quasi[1]catenanes. These pretzel-like molecules consist of two molecular rings ‘oppositely’ coupled at a central carbon atom. The research is published in the journal Nature Communications. “Our [...]…

(Arizona State University) On October 13, 2014 something very strange happened to the camera aboard NASA's Lunar Reconnaissance Orbiter (LRO). The Lunar Reconnaissance Orbiter Camera (LROC), which normally produces beautifully clear images of the lunar surface, produced an image that was wild and jittery. From the sudden and jagged pattern apparent in the image, the LROC team determined that the camera must have been hit by a tiny…

The Trump Administration has proposed a $19.1 Billion NASA budget request for Fiscal Year 2018, which amounts to a $0.5 Billion reduction compared to the recently enacted FY 2017 NASA Budget. Although it maintains many programs, the budget also specifies significant cuts and terminations to NASA’s Earth Science and manned Asteroid redirect mission as well […] The post Trump Proposes $19.1 Billion 2018 NASA Budget, Cuts Earth Science and Education appeared first on Universe T…

Almost two billion years ago, a 10-kilometre-wide chunk of space slammed down into rock near what is now the city of Sudbury. Now, scientists from Western University and the University of Portsmouth are marrying details of that meteorite impact with technology that measures surrounding crystal fragments as a way to date other ancient meteorite…

(NASA/Goddard Space Flight Center) El Niño is a recurring climate pattern characterized by warmer than usual ocean temperatures in the equatorial Pacific. Two back-to-back 3-D visualizations track the changes in ocean temperatures and currents, respectively, throughout the life cycle of the 2015-2016 El Niño event, chronicling its inception in early 2015 to its dissipation by April…

On May 25, 2017, NASA's Solar Dynamics Observatory, or SDO, saw a partial solar eclipse in space when it caught the moon passing in front of the sun. The lunar transit lasted almost an hour, between 2:24 and 3:17 p.m. EDT, with the moon covering about 89 percent of the sun at the peak of its journey across the sun's face. The moon's crisp horizon can be seen from this view because the moon has no atmosphere to distort the…
