James Webb Space Telescope could target tiny bright galaxies to shine light on dark matter
The James Webb Space Telescope could target tiny and bright galaxies in the early universe to unveil some secrets about the universe's most mysterious stuff, dark matter.
The universe might be younger than we think, galaxies' motion suggests
The motions of satellites in galaxy groups tell us that such groupings, and therefore possibly the universe, are younger than what standard cosmology tells us.
James Webb Space Telescope reveals distances of nearly 200 deep-space galaxies
We now know how far away some galaxies are in the iconic "deep field" image from NASA's James Webb Space Telescope. A Canadian instrument is revealing more about how the universe changed over time.
How did the universe's elements form?
We all know the universe contains a vast array of elements, ranging from light gases, such as helium, to heavy metals, like lead. But where did all of the elements come from?

Dark energy may allow black holes to live in 'perfect pair' binaries
Binary black holes are believed to inevitably spiral together, but dark energy and the expanding universe could help them maintain a safe distance and mimic a single black hole.
The James Webb Space Telescope's early galaxy images were oddly bright. Now we know why
Distant galaxies that existed a few hundred million years after the Big Bang are brighter than expected in JWST images because they were experiencing bursts of intense star formation.
Antimatter responds to gravity like Einstein predicted, major CERN experiment confirms
The new study marks the beginning of detailed and direct pursuit of the gravitational nature of antimatter, which remains puzzlingly scarce in the universe.
