Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

NASA’s DART mission precisely measured changes in asteroid Dimorphos’ orbit and the Didymos system’s heliocentric motion using radar, stellar occultations and space observations.

This new development could help scientists develop more accurate risk assessments. Researchers use glow-in-the-dark technology to track threat lurking in human body: 'A snapshot in time' first ...

Every year, thousands of children miss critical windows for early autism intervention—simply because diagnostic tools rely too much on subjective observation. Once that window closes, the ...

Scientists have drawn up the most accurate map of Antarctica, offering background to the continent’s response to climate change.

A new study investigates how “flex power”, a technology that dynamically redistributes satellite signal power to resist interference, affects positioning accuracy and navigation reliability.

For decades, global soil moisture monitoring from space has depended on reference datasets. Satellite observations, while indispensable, are rarely used alone; instead, their retrieval algorithms are ...

A new study reveals how forest management informed by Indigenous practices creates unexpected benefits for drought-prone ...

There were concerns that Asteroid 2024 YR4 could hit the moon or Earth.

Findings support kinetic impact technique for planetary defense.
