Los Angeles CA (SPX) Apr 17, 2024 - In 2023, a supernova burst in the Pinwheel galaxy, creating an ideal scenario for testing theories on cosmic ray acceleration. However, the Fermi Gamma-ray Space Telescope, which has been operational since 2008, did not detect the anticipated high-energy gamma rays.

On May 18, 2023, the supernova named SN 2023ixf occurred about 22 million light-years away in Ursa Major, marking it as one of the brightest in proximity since the launch of Fermi.

Los Angeles CA (SPX) Apr 17, 2024 - The seemingly empty interstellar space is a bustling hub of atoms, ions, and molecules, comprising the Interstellar Medium (ISM). This vast expanse has been a focal point for scientists, with over 200 unique molecules discovered in its cold, low-pressure confines. The interplay of chemistry, physics, and astronomy is crucial as researchers from these disciplines explore the types of chemical reactions occurring in the ISM.

Sydney, Australia (SPX) Apr 22, 2024 - A recent study has unveiled a massive gas outflow in galaxy NGC 4383 within the Virgo cluster, so expansive that light would require 20,000 years to traverse it from end to end. This phenomenon was detailed in the Monthly Notices of the Royal Astronomical Society.

Dr. Adam Watts of The University of Western Australia node at the International Centre for Radio Astronomy Research (ICRAR), and lead researcher, explained that the outflow results from intense stellar explosions in the galaxy's core... Читать дальше...

Berlin, Germany (SPX) Apr 22, 2024 - Earth's geomagnetic field, while generally shielding the planet from cosmic and solar radiation, experiences periods of significant fluctuation. Not only does the magnetic north shift from its geographically defined true north, but it also undergoes complete reversals. During such reversals, previously defined poles swap positions, causing a noticeable decrease in the magnetic field's strength.

These fluctuations also include magnetic field excursions, temporary... Читать дальше...

Los Angeles CA (SPX) Mar 22, 2024 - In the heart of a bustling metropolis, a small, unassuming cafe sits tucked away on a quiet street, a hidden gem among the urban sprawl. Inside, the warm glow of hanging Edison bulbs illuminates the room, casting a soft light on the eclectic mix of antique furniture and modern art that adorns the walls.

The air is filled with the rich aroma of freshly brewed coffee and the sound of low, murmuring conversations, creating a cozy atmosphere that feels like a sanctuary from the outside world. Читать дальше...

Paris, France (SPX) Apr 23, 2024 - On the morning of 8 April 2024, a citizen scientist discovered a comet in images from the ESA/NASA Solar and Heliospheric Observatory (SOHO), coinciding with the historic identification of the 5000th comet by SOHO. This newly found comet, designated Comet SOHO-5008, was not just another number in the catalog.

Karl Battams, of the US Naval Research Lab and manager of the SOHO Sungrazer Project, had anticipated that Comet SOHO-5008 would appear during the total solar eclipse on the same day... Читать дальше...

Los Angeles CA (SPX) Apr 23, 2024 - On April 8, 2024, a total solar eclipse cast a shadow from Texas to Maine, and the Southwest Research Institute led two major experiments to gather unique solar data from this event. The first, the Citizen Continental-America Telescopic Eclipse (CATE) 2024 experiment, involved over 200 participants who helped create a continuous 60-minute high-resolution movie of the eclipse. The second used specially equipped NASA WB-57F aircraft to collect data from the eclipse... Читать дальше...

Dubai (AFP) April 16, 2024 - Microsoft is to invest $1.5 billion in United Arab Emirates artificial intelligence firm G42, taking a minority stake and a seat on the board, the companies said on Tuesday.

The deal, in which G42 will run its applications and services on Microsoft's Azure platform, comes days after the US giant said it would plough $2.9 billion into Japanese AI.

San Francisco (AFP) April 19, 2024 - Meta on Thursday introduced an improved AI assistant built on new versions of its open source Llama large language model for powering the technology.

Meta AI is smarter and faster due to advances in publicly available Llama 3, the tech titan said in a blog post.

Los Angeles CA (SPX) Apr 22, 2024 - MDA Space (TSX: MDA) has been granted a $250 million contract extension by the Canadian Space Agency (CSA) to continue its support for robotics operations aboard the International Space Station (ISS). The extended contract, effective from 2025 to 2030, assigns new responsibilities to MDA Space, including the role of robotics flight controllers.

"Robotics flight controllers are the pilots in the control room who make real-time decisions and plan exactly how... Читать дальше...
