Quantum semiconductor design could expand search for dark matter

by quasarn01 | Jul 2, 2026 | Latest in Physics

Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that could help search for axions, hypothetical...

Analog gravity advance offers new insights into Hawking radiation from black holes

by quasarn01 | Jul 2, 2026 | Latest in Physics

Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint radiation themselves. This radiation has...

LSST begins full operations with key contributions from Japanese researchers and engineers

by quasarn01 | Jul 1, 2026 | Astronomy

NSF–DOE Vera C. Rubin Observatory has officially begun full operations for the Legacy Survey of Space and Time (LSST), one of the world’s largest astronomical imaging surveys. Behind the scenes, Japanese researchers and engineers are drawing on technologies and...

New star activity catalog could sharpen hunt for habitable worlds

by quasarn01 | Jul 1, 2026 | Astronomy

Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star’s habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises...

Cosmic dust could play key role in cracking long-standing mystery of solar corona heating

by quasarn01 | Jul 1, 2026 | Astronomy

A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly influence how energy moves through...

Nautilus array to track missing exoplanet atmospheres

by quasarn01 | Jul 1, 2026 | Astronomy

Exoplanet atmospheres have become prime targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can’t be directly imaged yet, so astronomers must get creative in how they search for signs of life, also called...

TESS just found a planet in a new way—and more may be hiding in its eight years of data

by quasarn01 | Jul 1, 2026 | Astronomy

For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound microlensing...

A new CRASH clock measures the chance of satellite collisions, and it’s ticking down fast

by quasarn01 | Jul 1, 2026 | Astronomy

Imagine a piece of space debris the size of a hockey puck slams into a Starlink satellite at about 10 kilometers per second. The kinetic energy is equivalent to 2 kilograms of TNT, or a fully loaded semitruck traveling at 100 kilometers an hour. Go to...

The universe is less uniform than we thought—cosmology may need a radical rethink

by quasarn01 | Jul 1, 2026 | Astronomy

Modern cosmology rests on a simple assumption: If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological principle. Go to Source

13,000 tons of space junk clutters Earth orbit. Here’s how it could be cleaned up

by quasarn01 | Jul 1, 2026 | Astronomy

Seventy years ago, Earth had only one satellite: the moon. Now it has more than 15,000—about 10,000 of which are owned by Elon Musk’s SpaceX. The world’s first trillionaire plans to launch 1 million more satellites, each roughly 70 meters (230 feet) long...

XMM-Newton and Chandra help revise distance to Milky Way’s outer spiral arms

by quasarn01 | Jul 1, 2026 | Astronomy

The European Space Agency’s XMM-Newton and NASA’s Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance to these echoes, they found...
