MeerKAT reveals three electron acceleration sites in one solar flare

Solar flares are the most explosive energy-release events in the solar corona, leading to intense particle acceleration, plasma heating and bulk plasma motions on short timescales. Core questions during solar flares remain unresolved, including how and where particle acceleration occurs, and how energized electrons propagate through coronal magnetic structures.

SpaceX’s hold over orbit matches East India Company’s grip on maritime trade

Elon Musk’s SpaceX holds sway over the emerging space economy in a way that has more in common with notorious colonial-era trading companies than the competitive markets of today’s textbooks, according to a new study.

Possible dark matter-deficient twins discovered in the Fornax Cluster

Astronomers have identified a possible new example of one of the universe’s strangest galaxy types: galaxies that appear to contain little or no dark matter. The newly studied pair, FCC 224 and FCC 240, on the outskirts of the Fornax Cluster, share several unusual traits with the only known pair of controversial dark-matter-deficient galaxies. The […]

Space telescopes are now overwhelmed by satellite trails

Unfortunately, there’s more bad news to report on the clear skies front. A new paper, available on the arXiv preprint server from researchers at NASA’s Ames Research Center, reports that 73.3% of images the agency’s new SPHEREx space telescope collected between May and September of last year were contaminated by at least one artificial satellite […]

Quantum memory surpasses classical limits for storing unknown quantum operations

Quantum memories, systems that store and retrieve information leveraging quantum mechanical effects, can outperform classical storage systems on some existing tasks. Yet these promising memories could also complete operations that are very difficult or impossible for classical systems, including the storage and retrieval of so-called isometry channels.

Artemis II moon mission research continues on Earth

Since NASA’s Artemis II crew members safely splashed down in the Pacific Ocean on April 10 after their record-setting mission around the moon, science teams have been busy collecting more data and combing through observations collected on the test flight. Results from these science investigations will help support safe human exploration of deep space and […]

NASA’s INCUS mission on road to launch, study storms from space

Teams working on NASA’s INCUS (Investigation of Convective Updrafts) mission, the first space-based survey of the dynamics of tropical convective storms, have completed assembly and tested two of the mission’s small satellites, or SmallSats. Testing continues on the third SmallSat and is scheduled for completion no earlier than September ahead of a 2027 launch.

Cosmic bombardment may have opened Earth’s crust for prebiotic chemistry

Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of the planet’s environment during that time is limited. However, samples from the moon and its cratered surface hint at the […]

Upcoming telescopes could shed light on dark matter

NASA’s plans to return astronauts to the moon through the Artemis program and ultimately send humans to Mars highlight just how far space exploration has come. Yet while the moon and Mars remain compelling destinations filled with scientific mysteries, looking beyond our solar system raises even deeper questions about the universe itself.
