The image shows that the telescope's 18 separate mirrors are now accurately aligned and acting as one, and the photo is even better than scientists hoped it would be, NASA officials said in a statement.

On Friday (March 18), the FDA issued an alert warning that at-home COVID-19 tests can cause harm if they are used improperly, for example, if the liquid test solution touches a person's skin or eyes, or if the small vials of liquid solution are swallowed, the agency said in a statement. The agency also reminded people to keep the tests out of reach of children and pets.

They arrived at 4:15 a.m. EDT, 10 hours and 28 minutes after the rollout began on Thursday (March 17) at 5:47 p.m. EDT. While 11 hours might sound like a long time for a 4-mile (6.4-kilometer) trip, the lunar rocket's arrival at Launch Pad 39B at the Kennedy Space Center in Cape Canaveral, Florida was right on schedule. It departed from Kennedy's Vehicle Assembly Building and traveled at a cruising speed of just under 1 mph (1.6 km/h) for much of the journey, carried by NASA's enormous Crawler-Transporter 2 (CT-2).

JE is caused by a flavivirus, which belongs to the same genus of viruses as those that cause yellow fever, dengue fever and West Nile fever, according to the Centers for Disease Control and Prevention (CDC). The virus gets transmitted to humans through the bites of infected mosquitoes of the Culex genus, and the mosquitoes initially pick up the virus from infected vertebrates, mainly pigs and wading birds, according to the CDC.

Astronomers detected the cosmic particle trail in images captured in X-rays by NASA's Chandra X-ray Observatory in space and in optical light by the Gemini North telescope in Hilo, Hawaii.

Hurt (IPAC)) Astronomers searching for our solar system's elusive Planet Nine — a theoretical world that may lurk deep in a cloud of icy rocks far beyond the orbit of Neptune — have come up short once again. In a recent paper published Dec. 23, 2021 in The Astrophysical Journal, researchers pored over six years of telescope data in an attempt to identify potential signs of Planet Nine in the southern sky. Captured with the Atacama Cosmology Telescope (ACT) in Chile between 2013 and 2019, the observations covered about 87% of the sky visible from the Southern Hemisphere.

The dead shark was first spotted on the sand in Newlyn Harbour, Cornwall, on the southwest coast of England, on March 13. But before experts could examine it, the tide came in and took the carcass back out to sea, according to Cornwall Wildlife Trust Twitter posts.
