This satellite constellation transformed earth science by creatively tuning in to GPS sign

When NASA's Cyclone Global Navigation Satellite System, or CYGNSS, launched into orbit in 2016, none of the University of Michigan Engineering researchers who developed the system expected it to transform earth science. They certainly had high hopes for the system's original miss

Could this asteroid be a piece of the moon? A Chinese spacecraft is about to find out

The moon is not the only natural object traveling through space alongside Earth. Several small asteroids travel around the sun in near lockstep with our planet. And just like Earth, these space rocks also take a year to complete a full orbit. Today, we know of eight such "quasi-m

Planned 1.7 million satellites 'devastating' for astronomy: Study

The 1.7 million satellites that companies are aiming to launch into Earth's orbit in the coming years will have "devastating consequences for astronomy," new research warned Wednesday.

Astronomers characterize 'improbable' system shaped by brown dwarf

In the course of studying planets beyond our solar system (6,316 confirmed exoplanets and counting), scientists have discovered some very interesting systems. Consider TOI-201, a compact system populated by three bodies, including a brown dwarf, orbiting on the same plane. The sy

A new net-membrane could clean up some tricky space debris

We've reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing orbital debris problem. But one simple design keep

Black hole collisions may follow entropy law, offering simpler remnant predictions

When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe. The event is so energetic that it significantly distorts the universe around it. It emits gravitational waves—ripples in the fabric of spacetime—

From the lab to the moon: Lunar cement alternative survives 6 months on ISS and returned s

Building material samples from the University of Delaware spent six months mounted outside the International Space Station, where the harsh conditions of low Earth orbit tested their limits.

Scientists discover rare 'super-Jupiter' planet with 180-day long orbit

Scientists from Queen's University Belfast have led an international team in the discovery of a rare new planet, which is larger than Jupiter and orbits a distant star every 180 days. Named NGTS-38 b, it is an exoplanet—a planet that orbits a star beyond our solar system. It is a

Astronomers dig deep to find tiny dangerous space debris

In a new study, published in the Journal of the Astronautical Sciences, Warwick researchers led an international effort to uncover some of the faintest debris in geosynchronous orbit ever observed, finding fragments as small as 5 centimeters (2 inches) and obtaining valuable data

Warm Jupiter exoplanet transiting a sun-like star discovered

An international team of astronomers reports the discovery of a new exoplanet orbiting a sunlike star as part of the Next Generation Transit Survey (NGTS). The newfound alien world, designated NGTS-39 b, is a Jupiter-sized planet with an equilibrium temperature of about 519 K. Th
