When Julian Lozos visited the site of the 2019 Ridgecrest earthquakes two days after the event, he noticed something strange. Pebble- to boulder-sized rocks had clearly been moved by the earthquakes—but there were no signs of dragging or shearing on the desert ground.
AI can bridge the growing gap between new and old solar observations and help scientists uncover overlooked aspects of our star’s long-term evolution, a new study argues. Continue ReadingHow AI is helping scientists unlock some of the sun’s deepest secrets
The Southern Pinwheel Galaxy (M83) in Hydra checks almost every box an amateur astronomer could desire. This stunning barred spiral spans a hefty 14′ and, at magnitude 7.5, ranks among the sky’s 10 brightest galaxies. Its only drawback is location — at a declination of –30°, it lies farther south than any other galaxy inContinue reading “M83: Big, bright, and beautiful” The post M83: Big, bright, and beautiful appeared first on Astronomy Magazine.

Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious.
The Texas Space Commission has awarded more than $26 million to five companies in the latest round of awards designed to stimulate the state’s space industry. The post Texas Space Commission awards $26 million to five companies appeared first on SpaceNews.
Astronomers from Swinburne University in Australia and elsewhere have employed the Keck II telescope to investigate the globular cluster system of an ultra-diffuse galaxy designated NGC5846_UDG1. Results of the observations, published April 4 on the arXiv pre-print server , could help us better understand the nature of this galaxy.
The solar eruption set Earth’s skies ablaze, with vibrant auroras visible across the Northern and Southern Hemispheres. Continue ReadingRare ‘cannibal’ solar eruption sparks severe geomagnetic storm, triggers stunning auroras (photos)
A team behind the rescue of two lunar satellites left stranded by a launch anomaly have revealed the challenges they faced in salvaging the mission. The post Mission team details complex rescue of Chinese lunar spacecraft appeared first on SpaceNews.
GPS is not only a cornerstone to our military superiority, it is foundational to our national and global economic stability. In fact, analysts warn that GPS outages could cost our […] The post Why Resilient GPS (R-GPS) Matters for US Military Superiority: We Must Address GPS Vulnerabilities appeared first on SpaceNews.
The detection of dark matter, the elusive type of matter predicted to make up most of the universe’s mass, is a long-standing goal in the field of astrophysics. As dark matter does not emit, reflect or absorb light, it cannot be observed using conventional experimental methods.
Here’s how and where to see the Lyrid meteor shower in 2025, which is active between April 16-25 and peaks on April 22. Continue ReadingWhere to see the Lyrid meteor shower 2025: Top viewing tips
A fog of long-wavelength infrared light could be produced by dusty, star-forming galaxies that have remained hidden — until now, that is. Continue ReadingVast swarms of hidden galaxies may be secretly bathing the universe in a soft glow
A bright object, initially appearing to be a meteorite, lit up the skies over Mexico’s capital around 3 a.m. Wednesday, stretching over plains, volcanoes and small towns.
Our sun, like all stars, is made mostly of hydrogen and helium. They are by far the most abundant elements, formed in the early moments of the universe. But our star is also rich in other elements astronomers call metals: carbon, nitrogen, iron, gold, and more. These elements were created through astrophysical processes, such as supernovas and neutron star collisions.
Scientists are currently planning two major space missions to search for life in space: NASA’s Project HWO and Project LIFE, led by ETH Zurich. If one of these missions were to discover life on an exoplanet, i.e., a planet outside of our solar system, this would be a sensational finding with implications far beyond science and would change our entire view of the world.
Scientists have reported new observations from NASA’s James Webb Space Telescope (JWST) that strengthen the case that the exoplanet K2-18 b has molecules in its atmosphere that, on Earth, are produced only by life. The work, announced Wednesday, builds on previous observations from JWST published in 2023 by the same team that yielded weak hintsContinue reading “K2-18 b could have dimethyl sulfide in its air. But is it a sign of life?” The post K2-18 Continue ReadingK2-18 b could have dimethyl sulfide in its air. But is it a sign of life?
