Not so dark with Alena Tensor: Math framework could explain dark matter without invisible particles
Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, ...
Young stars dim quickly in their X-ray output, potentially benefiting orbiting planets
Scientists have found that young stellar cousins of our sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA's Chandra X-ray Observatory. A paper ...

Torsion balances set strongest direct limits yet on ultralight dark matter
Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most past experiments have focused on heavier dark matter candidates, while much lighter dark matter, ...

Webb redefines the dividing line between planets and stars
Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.

Chandra explores interstellar medium of a bright low-mass X-ray binary
Using NASA's Chandra X-ray space telescope, astronomers have performed high-resolution X-ray spectroscopic observations of a bright low-mass X-ray binary known as GX 340+0. Results of the observational campaign, published ...
Could dark matter be made of black holes from a different universe?
New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.
