EarthSky Blog 11 Nov 2019, 10:39 UTC You’ve heard of panspermia, the idea that life exists throughout space and was carried to Earth by comets? What if the reverse occurred, with microbes on Earth ejected into space by asteroid impacts, escaping into the solar system billions of years ago?
NASASpaceFlight.com 11 Nov 2019, 01:56 UTC After a little under three months without a mission from Florida’s launch pads, SpaceX is set to launch a Falcon 9 rocket Monday morning. Liftoff from SLC-40 at the Cape Canaveral Air Force Station is scheduled for 9:50 to 10:01 AM EST (14:50 to 15:01 UTC) with the preferred launch time being 09:56 AM EST (14:56 UTC). The mission will carry the first group of operational Starlink satellites to orbit.
SPACE.com 10 Nov 2019, 12:00 UTC There may be a way of sneaking a peak at Schrödinger's cat — the famous feline-based thought experiment that describes the mysterious behavior of subatomic particles — without permanently killing the (hypothetical) animal.
SciTech Daily 8 Nov 2019, 08:56 UTC Scientists from Germany and the United States have unveiled the results of a newly-completed, state of the art simulation of the evolution of galaxies. TNG50 is the most detailed large-scale cosmological simulation yet. It allows researchers to study in detail how galaxies form, and how they have evolved since shortly after the Big Bang. For the first time, it reveals that the geometry of the cosmic gas flows around galaxies determines galaxies’ structures, and vice versa. The researchers publish their results in two papers in the journal Monthly Notices of the Royal Astronomical Society.
Astronomy Now 8 Nov 2019, 08:53 UTC Well positioned in the evening sky for viewers in the northern hemisphere, Messier 2, also known as NGC 7089, is one of the largest globular clusters known, with about 150,000 stars stretching across 175 light years. Thought to be about 13 billion years old, the cluster’s eccentric orbit carries it as far as 171,000 light years from the center of the Milky Way and up to 165,000 light years above and below the galactic plane.
NASASpaceFlight.com 8 Nov 2019, 08:52 UTC While the main focus last weekend was on the successful launch of the Cygnus NG-12 mission with a fresh set of science experiments and supplies for the Expedition 61 crew of the International Space Station, Northrop Grumman was eagerly awaiting the opportunity to test a critical new capability for Cygnus.
SciTech Daily 8 Nov 2019, 06:02 UTC Astronomers using the NASA/ESA Hubble Space Telescope have observed a galaxy in the distant regions of the Universe which appears duplicated at least 12 times on the night sky. This unique sight, created by strong gravitational lensing, helps astronomers get a better understanding of the cosmic era known as the epoch of reionization.
