Wellesley MA (SPX) Dec 13, 2024 - Stunning new photographs by a Wellesley College-led team of astronomers have revealed a newly forming galaxy that looks remarkably similar to a young Milky Way.

The extraordinary images - taken with NASA's James Webb Space Telescope - show a galaxy that glitters with 10 distinct star clusters that formed at different times, much like our own Milky Way.

Los Angeles CA (SPX) Dec 13, 2024 - The NASA/ESA Hubble Space Telescope has provided an extraordinary image of the spiral galaxy UGC 10043, located approximately 150 million light-years from Earth in the Serpens constellation. Viewed edge-on, this galaxy offers a rare perspective, with its spiral arms hidden from view, revealing a sharp profile against the cosmic backdrop.

In this edge-on orientation, UGC 10043's disk appears as a fine line, with dense dust lanes forming thick bands that obscure parts of the galaxy's radiant light. Читать дальше...

Tokyo, Japan (SPX) Dec 16, 2024 - The supermassive black hole at the heart of Messier 87 (M87), known for hosting a colossal relativistic jet, has produced a rare gamma-ray flare. This event marks the first high-energy gamma-ray outburst from M87 in over a decade, offering researchers an unprecedented opportunity to study the extreme conditions near a black hole's event horizon.

The findings, led by the Event Horizon Telescope (EHT) multi-wavelength working group, were published in *Astronomy and Astrophysics Journal*. Читать дальше...

Berlin, Germany (SPX) Dec 20, 2024 - A research team led by the Leibniz Institute for Astrophysics Potsdam (AIP) has pioneered a method to reconstruct the Milky Way's structure by mapping the orbits of stars. This approach reveals a deeper understanding of the galaxy's evolution and the distribution of stellar populations.

Despite advances in observational astronomy, much of the Milky Way remains hidden due to the obscuring effects of the interstellar medium and our position within the galactic disc. Читать дальше...

Greenbelt MD (SPX) Dec 13, 2024 - On April 8, 2024, a total solar eclipse swept across North America, from the western shores of Mexico, through the United States, and into northeastern Canada. For the eclipse, NASA helped fund numerous research projects and called upon citizen scientists in support of NASA's goal to understand how our home planet is affected by the Sun - including, for example, how our star interacts with Earth's atmosphere and affects radio communications.

At a press briefing on Tuesday, Dec. Читать дальше...

Berlin, Germany (SPX) Dec 13, 2024 - The Sun, known for its volatile nature, has exhibited unusually intense solar storms this year, creating auroras visible even at lower latitudes. However, new research suggests that the Sun and its stellar relatives are capable of even more powerful events called superflares, which release over one octillion joules of energy in brief bursts. These findings come from a study analyzing data from NASA's Kepler space telescope, revealing the frequency of these rare but potent solar events. Читать дальше...

Berlin, Germany (SPX) Dec 13, 2024 - The Sun powers life on Earth, generating immense energy through nuclear fusion and continuously releasing neutrinos - particles that provide insight into its inner workings. While modern neutrino detectors capture the Sun's present behavior, questions about its long-term stability over millions of years remain unanswered. Addressing this challenge is the focus of the LORandite EXperiment (LOREX), which requires precise measurements of the solar neutrino cross-section on thallium. Читать дальше...

Boston MA (SPX) Dec 17, 2024 - As seen across North America at sometimes surprisingly low latitudes, brilliant auroral displays provide evidence of solar activity in the night sky. More is going on than the familiar visible light shows during these events, though: When aurora appear, the Earth's ionosphere is experiencing an increase in ionization and total electron content (TEC) due to energetic electrons and ions precipitating into the ionosphere.

One extreme auroral event earlier this year... Читать дальше...

Baltimore MD (SPX) Dec 23, 2024 - NASA's Parker Solar Probe is in good health and operating normally as it speeds toward its closest-ever flight around the Sun on Christmas Eve.

Mission operators at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, received a beacon transmission from Parker, through NASA's Deep Space Network complex in Canberra, Australia, indicating all spacecraft systems were operating normally.

Los Angeles CA (SPX) Dec 23, 2024 - NASA and SpaceX have announced a revised target of September 2025 for the launch of the Interstellar Mapping and Acceleration Probe (IMAP) spacecraft. The updated schedule allows for additional time to complete final preparations for the IMAP flight systems ahead of its launch aboard a SpaceX Falcon 9 rocket.

IMAP's primary mission is to study the heliosphere, a protective magnetic bubble created by the Sun that shields the solar system from interstellar radiation. Читать дальше...

Fairbanks AK (SPX) Dec 26, 2024 - Newly published results from a 2021 experiment led by a University of Alaska Fairbanks scientist have begun to reveal the particle-level processes that create the type of auroras that dance rapidly across the sky.

The Kinetic-scale Energy and momentum Transport experiment - KiNET-X - lifted off from NASA's Wallops Flight Facility in Virginia on May 16, 2021, in the final minutes of the final night of the nine-day launch window.

Detroit MI (SPX) Dec 26, 2024 - When two probes orbiting the Sun aligned with one another, researchers harnessed the opportunity to track the Sun's magnetic field as it traveled into the solar system. They found that the sharply oscillating magnetic field smooths out to gentle waves while accelerating the surrounding solar wind, according to a University of Michigan-led study published in The Astrophysical Journal.

The sharp S-shaped bends of the magnetic fields streaming out of the Sun, called magnetic switchbacks... Читать дальше...

Greenbelt MD (SPX) Dec 28, 2024 - Operations teams have confirmed NASA's mission to "touch" the Sun survived its record-breaking closest approach to the solar surface on Dec. 24, 2024.

Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, NASA's Parker Solar Probe hurtled through the solar atmosphere at a blazing 430,000 miles per hour - faster than any human-made object has ever moved. A beacon tone received late on Dec. 26 confirmed the spacecraft had... Читать дальше...

Raleigh NC (SPX) Dec 16, 2024 - Researchers have demonstrated the ability to steal an artificial intelligence (AI) model without hacking into the device where the model was running. The technique is novel in that it works even when the thief has no prior knowledge of the software or architecture that support the AI.

"AI models are valuable, we don't want people to steal them," says Aydin Aysu, co-author of a paper on the work and an associate professor of electrical and computer engineering at North Carolina State University. Читать дальше...

Rome (AFP) Dec 20, 2024 - Italy's data protection authority on Friday said it had fined OpenAI 15 million euros over the use of personal data by ChatGPT, but the US tech firm said it would appeal.

The Italian Data Protection Authority (GPDP) watchdog began an investigation in March 2023 when it temporarily blocked ChatGPT in Italy over privacy concerns, becoming the first Western country to take action against the popular AI chatbot.
