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.

Read previewMicrosoft reorganized teams under Jared Spataro, its head of "AI at Work," shifting focus to its Copilot AI products and reducing the number of employees working on its Teams chat app, according to an excerpt of an internal memo shared with Business Insider. "In early 2022, we recognized the pandemic as a once-in-a-generation opportunity and we surged on Teams to win," Spataro wrote. AdvertisementMicrosoft spokesman Frank Shaw confirmed Spataro is putting more resources behind Copilot, but said Teams remains a core priority and Copilot is a part of Teams. Copilot for Teams, Shaw said, is the company's most used and loved Copilot according to customer surveys and research and will continue to be a focus of future investments. Microsoft is leaning into the potential of its new Copilot tools, built on OpenAI's GPT models, which so far have mixed feedback from customers.

CNN —When the total solar eclipse traces a path across Mexico, the United States and Canada on April 8, spectators can anticipate a multitude of awe-inspiring moments. For those living outside of the path of totality, a crescent-shaped partial eclipse, rather than a total eclipse, will be the main event. A partial solar eclipse is seen between clouds from Socorro in Sao Paulo, Brazil on October 14, 2023. The diamond ring effect is seen during the total solar eclipse on August 21, 2017, in St. Louis, Missouri. And we’re living at the right time to truly enjoy the sight of a total eclipse on Earth, he said.

Otherwise, experts say it’s absolutely necessary to wear certified eclipse glasses or use handheld solar viewers that meet a specific safety standard, known as ISO 12312-2, when watching all other phases of a total or partial solar eclipse. And sunglasses won’t work in place of eclipse glasses or solar viewers. Counterfeit eclipse glasses with black lenses that have straight left and right edges from China (top) are printed with text copied from real eclipse glasses, but the counterfeit glasses are missing the company address. Meanwhile, real eclipse glasses from American Paper Optics (bottom) have reflective lenses with curved left and right edges. Never look through an unfiltered optical device of any kind in this situation, even while wearing eclipse glasses.

The mystery is how OpenAI accesses enough YouTube content to make this work. Business Insider asked OpenAI whether it has downloaded YouTube videos at scale and whether the startup uses this content as data for AI model training. Google, OpenAI, and other tech companies are currently arguing that using copyrighted content for AI model training is also legal. And when pressed again about sources of training data, Murati replied, "I'm not going to go into the details."

CNN —Astronomers using the James Webb Space Telescope have detected commonplace chemical ingredients found in vinegar, ant stings and even margaritas around two young stars, according to NASA. The complex organic molecules they observed using the space observatory’s Mid-Infrared Instrument included acetic acid, a component of vinegar, and ethanol — otherwise known as alcohol. The team also found simple molecules of formic acid, which causes the burning sensation associated with ant stings, as well as sulfur dioxide, methane and formaldehyde. Stars form from swirling clouds of gas and dust, and the leftover material from star formation gives rise to planets. Detecting complex organic molecules in space is helping astronomers to determine the molecules’ origins as well as those of other larger cosmic molecules.

A new signal recently received from the spacecraft suggests that the NASA mission team may be making progress in its quest to understand what Voyager 1 is experiencing. Voyager 1’s flight data system collects information from the spacecraft’s science instruments and bundles it with engineering data that reflects the current health status of Voyager 1. But since November, Voyager 1’s flight data system has been stuck in a loop. On March 3, the team noticed that activity from one part of the flight data system stood out from the rest of the garbled data. The decoded signal included a readout of the entire flight data system’s memory, according to an update NASA shared.

The Azure OpenAI service has hundreds of developers supporting customers of Microsoft's Azure cloud service who use OpenAI's GPT models. Some Microsoft employees work so closely with OpenAI that they have badges to get into OpenAI's offices, and some OpenAI employees can badge into Microsoft locations.

CNN —A peculiar fossil has helped scientists discover an unusual bird that lived among the dinosaurs 120 million years ago, and the find is changing the way researchers think about avian evolution. Enantiornithines are known as “opposite birds” because they had a shoulder joint feature that greatly differs from the ones modern birds have. “Before Imparavis, toothlessness in this group of birds was known to occur around 70 million years ago,” Clark said. When Jingmai O’Connor, the Field Museum’s associate curator of fossil reptiles, visited the Shandong museum’s collections a few years ago, the fossil caught her attention. While modern birds have fused forelimb digits, enantiornithines still had independent movement in the “little fingers” on their wings.

CNN —Astronomers have spotted the oldest “dead” galaxy ever observed while studying the cosmos with the James Webb Space Telescope, and it’s one of the deepest views into the distant universe made with the observatory to date. The galaxy existed when the universe was only about 700 million years into its current age of about 13.8 billion years. But something made the galaxy suddenly halt star formation almost as quickly as star birth had begun more than 13 billion years ago, and the researchers have yet to uncover the cause. Studying the galaxy could reveal new insights about the early universe and the factors that affect star formation within galaxies, according to the authors. “Until now, to understand the early universe, we’ve used models based on the modern universe.

CNN —When NASA’s Double Asteroid Redirection Test spacecraft intentionally slammed into the asteroid Dimorphos in September 2022, the impact may have caused “global deformation” of the space rock, according to new research. Dimorphos is a moonlet asteroid that orbits a larger parent asteroid known as Didymos. The DART mission ended upon impact, but prior to colliding with Dimorphos, the spacecraft transmitted an incredibly detailed view of the little asteroid’s boulder-covered surface that is helping researchers learn more about how the space rock formed. Rather than forming a simple crater on Dimorphos, the DART impact reshaped the entire asteroid, the results have suggested.

CNN —Astronomers have spotted an unusual sign that a dead star feasted on a fragment of a planet orbiting it: a metal scar on the star’s surface. The observation revealed a metallic feature on the star’s surface that the researchers determined was related to a change detected in the star’s magnetic field. The strength of the metal detection also synced with changes observed in the star’s magnetic field, which led the team to determine that the metal scar was located on one of the star’s magnetic poles. The star’s magnetic field pulled the metals toward the star, which led to the presence of the scar, the finding has suggested. But WD 0816-310 presents an entirely different scenario orchestrated by the star’s magnetic field.
