Direct link NASA’s James Webb Space Telescope Completes Final Functional Tests to Prepare for Launch

1 Mar 2021, 16:45 UTC February marked significant progress for NASA’s James Webb Space Telescope, which completed its final functional performance tests at Northrop Grumman in Redondo Beach, California. Testing teams successfully completed two important milestones that confirmed the observatory’s internal electronics are all functioning as intended, and that the spacecraft and its four scientific instruments can send and receive data properly through the same network they will use in space. These milestones move Webb closer to being ready to launch in October.

26 Feb 2021, 15:00 UTC This image taken with the NASA/ESA Hubble Space Telescope features NGC 4826 — a spiral galaxy located 17 million light-years away in the constellation of Coma Berenices (Berenice’s Hair). This galaxy is often referred to as the “Black Eye” or “Evil Eye” galaxy because of the dark band of dust that sweeps across one side of its bright nucleus.

Direct link The Smallest Galaxies in Our Universe Bring More About Dark Matter to Light

24 Feb 2021, 08:12 UTC Our universe is dominated by a mysterious matter known as dark matter. Its name comes from the fact that dark matter does not absorb, reflect or emit electromagnetic radiation, making it difficult to detect. Now, a research team including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) Project Assistant Professor Satoshi Shirai has investigated the strength of dark matter scattered across the smallest galaxies in the universe using stellar kinematics.

23 Feb 2021, 18:48 UTC NASA’s Artemis I Orion spacecraft is being outfitted with additional artwork as technicians began installing the logo for ESA (European Space Agency). ESA provided the European-built service module, which provides power and propulsion for the Orion spacecraft, and will also provide water and air for astronauts on future mission.

22 Feb 2021, 18:25 UTC New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds from Mars.

22 Feb 2021, 16:00 UTC For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA’s Neil Gehrels Swift Observatory, they traced the neutrino to a black hole tearing apart a star, a rare cataclysmic occurrence called a tidal disruption event.

Direct link NASA’s Webb Telescope Will Show Us More Stars at Higher Resolution—Here’s What That Means for Astronomy

22 Feb 2021, 14:00 UTC The combination of high resolution and infrared-detecting instruments on NASA’s upcoming James Webb Space Telescope will reveal stars that are currently hidden even from the powerful Hubble Space Telescope. The wealth of additional star data will allow astronomers to investigate a range of questions, from star birth to star death to the universe’s elusive expansion rate. Early observations with Webb will demonstrate its ability to distinguish the individual light of stars in the local universe in a range of environments and provide astronomers with tools for making the most of Webb’s powerful capabilities.

15 Feb 2021, 10:01 UTC The Chicxulub impactor, as it's known, left behind a crater off the coast of Mexico that spans 93 miles and runs 12 miles deep. Its devastating impact brought the reign of the dinosaurs to an abrupt and calamitous end by triggering their sudden mass extinction, along with the end of almost three-quarters of the plant and animal species living on Earth
