Tracking undetectable space junk      (via sciencedaily.com)     Original source 

Satellite and spacecraft operators may finally be able to detect small pieces of debris orbiting Earth using a new approach. Colliding pieces of space debris emit electric signals that could help track small debris littering Earth's orbit, potentially saving satellites and spacecraft.

Ghostlike dusty galaxy reappears in James Webb Space Telescope image      (via sciencedaily.com)     Original source 

Astronomers studying images from the James Webb Space Telescope have identified an object as a 'dusty star-forming galaxy' from nearly 1 billion years after the Big Bang. They have also discovered more than a dozen additional candidates, suggesting these galaxies might be three to 10 times as common as expected. If that conclusion is confirmed, it suggests the early universe was much dustier than previously thought.

Meteorites likely source of nitrogen for early Earth      (via sciencedaily.com)     Original source 

Micrometeorites originating from icy celestial bodies in the outer Solar System may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system.

A new possible explanation for the Hubble tension      (via sciencedaily.com)     Original source 

The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values. This so-called 'Hubble tension' poses a puzzle for cosmologists. Researchers are now proposing a new solution: Using an alternative theory of gravity, the discrepancy in the measured values can be easily explained -- the Hubble tension disappears.

2D material reshapes 3D electronics for AI hardware      (via sciencedaily.com)     Original source 

Researchers demonstrated monolithic 3D integration of layered 2D material into novel processing hardware for artificial intelligence computing. The new approach provides a material-level solution for fully integrating many functions into a single, small electronic chip -- and paves the way for advanced AI computing.

Rocky planets can form in extreme environments      (via sciencedaily.com)     Original source 

Astronomers have provided the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our galaxy. These results suggest that the conditions for terrestrial planet formation can occur in a possible broader range of environments than previously thought.

Building blocks for life could have formed near new stars and planets      (via sciencedaily.com)     Original source 

While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. The simplest amino acid, carbamic acid, could have formed alongside stars or planets within interstellar ices. The findings could be used to train deep space instruments like the James Webb Space Telescope to search for prebiotic molecules in distant, star-forming regions of the universe.

Astronomers discover disc around star in another galaxy      (via sciencedaily.com)     Original source 

In a remarkable discovery, astronomers have found a disc around a young star in the Large Magellanic Cloud, a galaxy neighboring ours. It's the first time such a disc, identical to those forming planets in our own Milky Way, has ever been found outside our galaxy. The new observations reveal a massive young star, growing and accreting matter from its surroundings and forming a rotating disc.

Composition of asteroid Phaethon      (via sciencedaily.com)     Original source 

Asteroid Phaethon, which is five kilometers in diameter, has been puzzling researchers for a long time. A comet-like tail is visible for a few days when the asteroid passes closest to the Sun during its orbit. However, the tails of comets are usually formed by vaporizing ice and carbon dioxide, which cannot explain this tail. The tail should be visible at Jupiter's distance from the Sun.
