The office will be located at Johnson Space Center in Houston.

Bird species that breed with several sexual partners have fewer harmful mutations, according to a study led by the Milner Centre for Evolution at the University of Bath. The study, published in Evolution, shows for the first time how polygamy increases the ef…

A study published in the journal Geology uses isotopes of sulfur to fingerprint the sources of sulfuric acid that have carved unique and beautiful cave systems in the Pyrenees mountains of southern France.

The Starliner team works to finalize the mate of the crew module and new service module for NASA's Boeing Crew Flight Test that will take NASA astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams to and from the International Space Station.

The telescope is currently orbiting more than 1 million miles from Earth.

A radio signal nearly 9 billion light-years away from Earth was reportedly captured in a new recording, detected by the Giant Metrewave Radio Telescope in India.

An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting "cosmic dawn"—the era after the Big Bang when stars first ignited and galaxies began to bloom.

It has been believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, must be large to produce a lot of thrust. Now, a new study from the University of Michigan suggests that smaller Hall thrusters can generate much more thr…

The quest for atmospheric spectral signatures that may witness biological activity in exoplanets is focused on rocky planets.

Using the James Webb Space Telescope, astronomers discover a rich catalog of frigid interstellar ice in the depths of a dark, dense molecular cloud.

Why do people hold highly variable attitudes toward well-evidenced science? For many years researchers focused on what people know about science, thinking that "to know science is to love it." But do people who think they know science actually know science?

Two newly discovered planets, about as massive as Earth, orbit within the habitable zone around their star – in a system only 16 light-years away.
