Dark energy may allow black holes to live in 'perfect pair' binaries

By Robert Lea published

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

By Keith Cooper published

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.

A large galaxy takes up the entirety of the image. The galaxy has a bright white core, and several large spiral arms extending out from that core, rotating clockwise. The arms are light blue with many pink speckles and clumps littering the arms. The background is also filled with a smattering of white and pink dots.

James Webb Space Telescope deepens major debate over universe's expansion rate
