NASA will launch sounding rockets and WB-57 high-altitude planes to conduct research on aspects of the sun and Earth that‘s only possible during an eclipse. During the 2017 eclipse that crossed the US, NASA and other space agencies conducted observations using 11 different spacecraft and two high-altitude planes. Three sounding rockets will launch from NASA's Wallops Flight Facility on April 8 to study the eclipse. During the 2023 annular eclipse, instruments on the rockets measured sharp, immediate changes in the ionosphere. The jets have custom noses that can carry specialized scientific instruments.

New York CNN —Pi Day isn’t just about showing off how many numbers you have memorized – restaurants from Burger King to California Pizza Kitchen are offering deals and discounts on Thursday, March 14th. Pi Day has also become synonymous with pizza pie (and other round foods) – here are some deals to round out your celebration. Pizza HutFrom March 12-14, Pizza Hut has been offering a free large one-topping pizza with purchase of a large menu-priced pizza. 7-ElevenLoyalty members can get any flavor large pizza for $3.14 in 7-Eleven, Speedway and Stripes stores – limited to one transaction, two per day. Burger KingAs part of its week of breakfast deals, Burger King is offering a free Hershey’s sundae pie with a $3.14 purchase.

CNN —Scientists have peered into the early days of the universe, when it was about 1 billion years old, and discovered that things moved in slow motion compared with now. Unlocking what happened during the early days of the universe can help scientists tackle the biggest mysteries about its origin, how it evolved and what the future holds. “This expansion of space means that our observations of the early universe should appear to be much slower than time flows today. While very bright, supernovas become much harder to observe at greater distances from Earth, which means that astronomers needed another source that would be visible deeper in the early universe. “What we have done is unravel this firework display, showing that quasars, too, can be used as standard markers of time for the early universe.”

On Wednesday evening, an international consortium of research collaborations revealed compelling evidence for the existence of a low-pitch hum of gravitational waves reverberating across the universe. “I like to think of it as a choir, or an orchestra,” said Xavier Siemens, a physicist at Oregon State University who is part of the North American Nanohertz Observatory for Gravitational Waves, or NANOGrav, collaboration, which led the effort. Scientists said that, so far, the results were consistent with Albert Einstein’s theory of general relativity, which describes how matter and energy warp space-time to create what we call gravity. “The gravitational-wave background was always going to be the loudest, most obvious thing to find,” said Chiara Mingarelli, an astrophysicist at Yale University and a member of NANOGrav. “This is really just the beginning of a whole new way to observe the universe.”

CNN —Astronomers have detected the most distant known organic molecules in the universe using the James Webb Space Telescope. It’s the first time Webb has detected complex molecules in the distant universe. The complex molecules were found in a galaxy known as SPT0418-47, located more than 12 billion light-years away. The galaxy observed by the Webb telescope shows an Einstein ring caused by a phenomenon known as gravitational lensing, which occurs when two galaxies are almost perfectly aligned from our perspective on Earth. Investigating the early universeAstronomers spotted the signature of the organic molecules during a careful analysis of Webb’s data.

But a black hole can also send powerful jets of material blasting across space and beyond its home galaxy. Previous observations have shown the jet and black hole separately, including the first direct image of a black hole, released in 2019. Astronomers believe that more material is falling toward the black hole in the new image, which is why the ring looks bigger. Studying black holesRecently, astronomers also used machine learning to release a cleaner, sharper version of the original M87 black hole image from 2019. The central region is darker and larger, surrounded by a bright ring as hot gas falls into the black hole.
CNN —The first photo ever taken of a black hole looks a little sharper now. The central region is darker and larger, surrounded by a bright ring as hot gas falls into the black hole in the new image. The Event Horizon Telescope Collaboration, called EHT, is a global network of telescopes that captured the first photograph of a black hole. Computers using PRIMO analyzed more than 30,000 high-resolution simulated images of black holes to pick out common structural details. But if heated materials in the form of plasma surround the black hole and emit light, the event horizon could be visible.
