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.

What happens to a star that captures a primordial black hole?

We don’t know whether theorized primordial black holes (PBH) are real. If they are, they formed in the very early universe, when physics was much different. They had no stellar progenitors and were created by the direct collapse of densely packed subatomic matter. Theorists have wondered whether PBH could be dark matter, or a component […]

Plants could be used to grow medicines in space, study shows

Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego. The team developed a simple method to grow and repeatedly harvest pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large […]

Neutron star merger simulations gain new precision with AI-driven r-process heating

Using a novel simulation model based on machine learning, an international research team at GSI/FAIR has succeeded in gaining a deeper understanding of element formation in stellar events such as neutron star mergers. For the first time, the scientists used deep learning with a neural network to model the energy release during r-process nucleosynthesis in […]

Astronomers discover the earliest known flickering quasar

A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and falls onto a black hole, it lights up its vicinity, radiating a huge amount of […]

Black hole feeding bursts may explain JWST’s Little Red Dots in early universe

A new theoretical study may have cracked one of the most puzzling discoveries of the James Webb Space Telescope (JWST): Little Red Dots, spotted across the early universe. The paper, posted to the arXiv preprint server on May 29, argues that these objects could be black holes caught in rare, violent bursts of feeding at […]

How Artemis II livestreamed hi-def videos and images from the moon to Earth

This April, humanity had front-row seats to space as the Artemis II Orion spacecraft transmitted crystal-clear footage of its historic journey around the moon from more than 250,000 miles (about 402,000 kilometers) back to Earth at speeds on par with home internet connections.

Mysterious signals keep coming from space: Astronomers find their ‘Rosetta stone’

A pair of stars spiraling around each other. That’s the origin of a new source of repeating radio bursts we’ve detected, called ASKAP J1745.

Could the Milky Way’s missing mass be hiding in a swarm of interstellar comets?

3I/ATLAS has caused quite a stir over the last year, inviting astronomers to update what they know about other solar systems as well as our own. However, this third interstellar visitor may have an unexpected impact on our understanding of dark matter. A new paper, available on the arXiv preprint server from researchers at the […]

Lunar orbiter concept could reveal five key elements across moon in two years

Researchers from Tokyo Metropolitan University have used simulations to show that a newly developed, compact X-ray telescope could be used to map the chemical composition of the entire lunar surface, a vital breakthrough for understanding its geological evolution. Detailed modeling of the detector and a realistic satellite mission show that two years would be enough […]

A faster way to forecast alien weather

The TRAPPIST-1 system, located about 41 light years from Earth, has been a focal point of much exoplanetary discussion—mainly because it has seven confirmed planets orbiting a dim M-dwarf star. Two of those planets—TRAPPIST-1e and -1f—are thought to be in the star’s habitable zone. However, the habitable zone of M-dwarfs is so close to the […]

Smart surfaces face zero gravity test in boiling heat experiments

A research team led by Davoud Jafari at the University of Twente, in collaboration with the University of Pisa, has completed a series of parabolic flight experiments to investigate advanced smart surfaces under rapidly changing gravity conditions. Conducted aboard the Air Zero G aircraft operated by Novespace, the campaign integrated additive manufacturing, boiling heat transfer […]

MUSE maps spiral galaxy W2246f, uncovering old core and ongoing star formation across disk

Astronomers have employed the Multi-Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to perform deep spectroscopic observations of a peculiar spiral galaxy known as W2246f. Results of the observational campaign, published May 27 on the pre-print server arXiv, offer new insights into how this galaxy evolved and shed more light on its nature. […]

SpaceX signs pre-IPO deal to provide AI computing to Google

SpaceX on Friday signed a blockbuster cloud computing agreement under which Google will pay the Elon Musk-founded rocket company $920 million per month for access to a massive cluster of AI chips, according to a disclosure in its initial public offering filing.
