A single origin story for the Milky Way's most mysterious stars

Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied explanation. Astronomers have proposed various competing t

Pegasus launch to deploy LINK for months‑long orbit boost of aging Swift

A mission to raise the orbit of NASA's Neil Gehrels Swift Observatory is poised for launch no earlier than Tuesday, June 30, at 6:23 a.m. EDT (10:23 p.m. UTC+12), from Kwajalein Atoll, part of the Republic of the Marshall Islands in the South Pacific Ocean.

Astronomers found two rare super puff planets lighter than cotton candy

Two newly confirmed "super-puff" planets are so diffuse that they are less dense than cotton candy, despite being about the size of Jupiter. Their rare orbital relationship and enormous, lightweight atmospheres could provide valuable clues about how some of the strangest planets

Giant exoplanet may hold a magnetic grip on its host star

Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.

NASA tests new refuel device for future in-space refueling missions

For NASA's next generation of deep-space exploration missions, spacecraft may need to refuel in Earth orbit before pushing farther into the solar system. Similar to how a gas pump needs a nozzle to fit your fuel tank, future spacecraft could require a special device in order to f

Testing the orbital mechanics of giant mirrors

Giant mirrors in space have been a staple of science fiction for decades. But so far, there's been very little work looking at the actual physics behind the concept—possibly because we're still so far from making them ourselves. Still, they could potentially serve as a passive te

Nearby 'Super Earth' may be a better candidate for life than previously thought

Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits a small, cool star called a red dwarf. Just 25 light-years

13,000 tons of space junk clutters Earth orbit. Here's how it could be cleaned up

Seventy years ago, Earth had only one satellite: the moon. Now it has more than 15,000—about 10,000 of which are owned by Elon Musk's SpaceX. The world's first trillionaire plans to launch 1 million more satellites, each roughly 70 meters (230 feet) long and 20 meters (66 feet) w

TESS just found a planet in a new way—and more may be hiding in its eight years of data

For the first time, NASA's TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound microlensing world is a super-Jupit

New star activity catalog could sharpen hunt for habitable worlds

Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star's habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises approximately 75% of the p

Space startup to launch India's first private orbital rocket

Indian startup Skyroot Aerospace said Thursday it would hold the maiden test flight of the country's first privately developed orbital-class rocket in the coming weeks.

Orbitronics clears key hurdle with direct orbital currents, boosting signals 100-fold

Researchers at Johannes Gutenberg University Mainz (JGU) are the first to directly utilize orbital currents without the need for conversion of the orbital current into a spin current.
