Scientists mapped dark matter around galaxies in the early universe
Scientists have mapped out the dark matter around some of the earliest, most distant galaxies yet. The 1.5 million galaxies appear as they were 12 billion years ago, or less…
The Windchime experiment could use gravity to hunt for dark matter ‘wind’
The secret to directly detecting dark matter might be blowin’ in the wind. The mysterious substance continues to elude scientists even though it outweighs visible matter in the universe by…

New Gaia data paint the most detailed picture yet of the Milky Way
1.6 billion stars. 11.4 million galaxies. 158,000 asteroids. One spacecraft. The European Space Agency’s Gaia space observatory, which launched in 2013, has long surpassed its goal of charting more than…
Information energy accounts for dark energy, resolves Hubble tension, avoids the ‘big chill,’ and is falsifiable
Stellar heated gas and dust in the Centaurus-A galaxy. Credit: NASA Hubble. Stellar heated gas and dust has an entropy, or information content, with an equivalent energy of 1070 joules,…
Astrophysicists simulate a fuzzy dark matter galactic halo
Density slices zooming into a fuzzy dark matter halo. The plot on the right shows the reconstructed fuzzy dark matter wave function with self-consistent interference pattern and central solitonic core…
A century ago, Alexander Friedmann envisioned the universe’s expansion
For millennia, the universe did a pretty good job of keeping its secrets from science. Ancient Greeks thought the universe was a sphere of fixed stars surrounding smaller spheres carrying…
