The findings suggest our galaxy’s core may contain less dark matter than previously estimated.

A low carbon abundance in planetary atmospheres, which the James Webb Space Telescope can detect, could be a signature of habitability.

Using multiple observatories, astronomers directly detect tellurium in two merging neutron stars.

Researchers achieve a landmark in quantum squeezing.

The frosty gas giant was discovered in a system that also hosts a warm Jupiter.

Astronomers discover the last three planets the Kepler telescope observed before going dark.

Statistics tools support the idea that all radio bursts may repeat if observed long enough.

Earth will meet a similar fate in 5 billion years.

The event was spotted in infrared data — also a first — suggesting further searches in this band could turn up more such bursts.

Current measurements of black holes are not enough to nail down how the invisible giants form in the universe, researchers say.
