NASA's Goddard Space Flight Center 31 Jan 2018, 19:00 UTC Tick, tick, tick. The device — a Geiger counter strapped to a miniature tape recorder — was registering radiation levels a thousand times greater than anyone expected. As the instrument moved higher, more than 900 miles above the surface, the counts ceased. Scientists were baffled. It was early 1958, the United States had just launched its first spacecraft, and a new discipline of physics was about to be born.
ESO Top News 31 Jan 2018, 11:00 UTC A dark cloud of cosmic dust snakes across this spectacular wide field image, illuminated by the brilliant light of new stars. This dense cloud is a star-forming region called Lupus 3, where dazzlingly hot stars are born from collapsing masses of gas and dust. This image was created from images taken using the VLT Survey Telescope and the MPG/ESO 2.2-metre telescope and is the most detailed image taken so far of this region.
NASA's Jet Propulsion Laboratory News and Features 30 Jan 2018, 19:42 UTC A panoramic image that NASA's Curiosity Mars rover took from a mountainside ridge provides a sweeping vista of key sites visited since the rover's 2012 landing, and the towering surroundings.
National Radio Astronomy Observatory (NRAO) 30 Jan 2018, 19:00 UTC The nearby dwarf galaxy known as the Large Magellanic Cloud (LMC) is a chemically primitive place. Unlike the Milky Way, this semi-spiral collection of a few tens-of-billions of stars lacks our galaxy’s rich abundance of heavy elements, like carbon, oxygen, and nitrogen. With such a dearth of heavy elements, astronomers predict that the LMC should contain a comparatively paltry amount of complex carbon-based molecules. Previous observations of the LMC seem to support that view.
Cherenkov Telescope Array 30 Jan 2018, 10:34 UTC Written by: Fabian Schüssler After years of preparation, a fundamentally new domain of astronomy and astrophysics has shown its first results: multi-messenger astrophysics. Throughout the past decade, several new astrophysical messengers have provided us with new insights into the most violent phenomena in the Universe: starting with high-energy gamma rays, the detection of an astrophysical flux of high-energy neutrinos and the first direct detection of gravitational waves. Building on these significant breakthroughs, many high-energy astrophysics observatories and groups started to work towards a dream that is now coming true: multi-messenger astrophysics, which, via the exchange and combination of data from very different observatories and messengers, opens new windows and provides unprecedented insights into the most violent phenomena ever observed. Above: Artist’s illustration of the recent merger of a binary neutron star system emitting gravitational waves and creating a gamma-ray ray burst and a kilonova. Credit: NASA’s Goddard Space Flight Center/CI Lab The most striking example illustrating the viability of this approach is the detection of electromagnetic signals complementing gravitational waves from the merger of a binary neutron star system. This event, named GW170817, is probably the best-covered astrophysical phenomenon in recent history. Thanks to the huge effort by observatories around ...
SETI Institute 29 Jan 2018, 18:44 UTC If you say you believe space aliens exist, I doubt your friends will be shocked. In a universe aglow with 2 trillion galaxies, you'd be supremely smug to think that Earth alone hosts clever creatures. One 2015 poll showed that 54 percent of Americans feel confident that intelligent aliens are out there.
NASA's Goddard Space Flight Center 29 Jan 2018, 17:30 UTC NASA’s James Webb Space Telescope will soon be on the move, and in order to find it, you will need to follow the STTARS. Webb telescope, or Webb, is NASA’s upcoming infrared space observatory, which is scheduled to launch in 2019. Transporting something as large and as delicate as Webb is no easy task. Enter the Space Telescope Transporter for Air, Road and Sea — or STTARS — a specially engineered shipping container that safely carries Webb from one location to another.
NASA's Goddard Space Flight Center 26 Jan 2018, 16:26 UTC This image from the NASA/ESA Hubble Space Telescope reveals a glistening and ancient globular cluster named NGC 3201 — a gathering of hundreds of thousands of stars bound together by gravity. NGC 3201 was discovered in 1826 by the Scottish astronomer James Dunlop, who described it as a “pretty large, pretty bright” object that becomes “rather irregular” towards its center.
