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

Researchers achieve a landmark in quantum squeezing.

Microbial or fungal biofilms on spacecraft can clog hoses and filters, or make astronauts sick. Space Station tests show that a surface treatment can help.

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

A new technique uses remote images to gauge the strength of ancient and active rivers beyond Earth.

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.

Robotic parts could be assembled into nimble spider bots for exploring lava tubes or heavy-duty elephant bots for transporting solar panels.
