Did you know that spiders can fly?
A tiny satellite has set out to investigate the halo of incredibly hot gas surrounding the Milky Way — and it could help scientists track down the huge amount of missing matter in the universe.
Jeff Bezos’ rocket company plans to charge passengers about $200,000 to $300,000 for its first trips into space next year, two people familiar with its plans told Reuters.
For decades, astronomers have puzzled over the variability of young stars residing in Taurus-Auriga dark clouds, a group of molecular clouds located in the constellations of Taurus and Auriga, about 450 light-years away. Since 1937, they have recorded noticeable dips in the brightness of RW Aur A — the primary star of a low-mass binary system — every few decades. Each dimming event appeared to last for about a month. In 2011, the star dimmed again, this time for about half a year. RW Aur A eventually brightened, only to fade again in mid-2014. In November 2016, the star returned to its full luminosity. Now Hans Moritz Günther of MIT and co-authors have observed RW Aur A using NASA’s Chandra X-Ray Observatory. They’ve found evidence for what may have caused its most recent dimming event: a collision of two protoplanetary bodies, which produced in its aftermath a dense cloud of gas and dust. As this planetary debris fell into RW Aur A, it generated a thick veil, temporarily obscuring the star’s light.
The mysterious surface of Saturn’s huge moon Titan comes into gloriously sharp focus in newly released photos captured by NASA’s Cassini spacecraft.
The nearly massless particles appear to travel at virtually the speed of light
The survey also confirmed the existence of two other moons, whose discovery was announced last year
Michael Hayduk, chief of the computing and communications division at the Air Force Research Laboratory says quantum technology will be “disruptive” in areas like data security and GPS-denied navigation.
An asteroid first discovered last year has now been confirmed to be one of only four equal mass binary systems ever detected near Earth.
