Jovian vortex hunters contribute to storm study

Jumping Jupiter! The results are in, storm chasers! Thanks to your help over the last two years, the Jovian Vortex Hunter project has published a catalog of 7,222 vortices, which you can download. Each vortex is an enormous swirling windstorm in Jupiter’s atmosphere–terrifying yet beautiful to behold.

Current generated by the quantum Hall effect found to have additional magnetic properties

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of atoms. This has been demonstrated by the calculations of a team from Martin Luther University Halle-Wittenberg (MLU), which are now published […]

When you wish upon a star, is it already dead? An astronomer crunches the numbers

When you wish upon a star, Jiminy Cricket told us, your dreams come true. But according to an idea doing the rounds on social media, that may not be the case:

Citizen scientists help map geomagnetic superstorm’s ionospheric impact

As seen across North America at sometimes surprisingly low latitudes, brilliant auroral displays provide evidence of solar activity in the night sky. More is going on than the familiar visible light shows during these events, though: When aurora appear, the Earth’s ionosphere is experiencing an increase in ionization and total electron content (TEC) due to […]

First-ever binary star found near our galaxy’s supermassive black hole

An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the center of our galaxy. It is the first time a stellar pair has been found in the vicinity of a supermassive black hole.

Image: Artemis II core stage moves to High Bay 2

In this image from Dec. 11, 2024, the 212-foot-tall SLS (Space Launch System) core stage is lowered into High Bay 2 at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. With the move to High Bay 2, NASA and Boeing technicians now have 360-degree access to the core stage both internally and […]

Building concrete on Mars from local materials

Imagine you’ve just gotten to Mars as part of the first contingent of settlers. Your first challenge: build a long-term habitat using local materials. Those might include water from the polar caps mixed with specific surface soils. They might even require some very personal contributions—your blood, sweat, and tears. Using such in situ materials is […]

NASA finalizes strategy for sustaining human presence in low Earth orbit

As part of the agency’s efforts to enable broader use of space, NASA has released its final goals and objectives for low Earth orbit, defining the long-term approach toward advancing microgravity science, technology, and exploration for the benefit of all.

ALMA observations investigate disk and jet of a massive protostar

Astronomers from Italy and Spain have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a massive protostar designated IRAS 20126+4104. The observational campaign, detailed in a paper published Dec. 9 on the arXiv preprint server, delivers important insights into the protostar’s disk and jet system.

Veteran Combat Pilot Alex Dietrich Describes Tic Tac UFO Encounter

Retired Navy Lt. Commander Alex Dietrich, a veteran combat pilot, gave an eye-witness account of a Tic Tac UFO. Dietrich spoke to Anderson Cooper about what she saw off the coast of San Diego in 2004. At the time, she was on a routine training mission off the USS Nimitz aircraft carrier 100 miles […]

Detecting the gravitational wave memory effect from core-collapse supernovae

Einstein’s theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is “gravitational wave memory”—the prediction that a passing gravitational wave will permanently change the distance between cosmic objects.

UFOs Outstrip Our Arsenal by 1,000 Years, Says Navy Witness Sean Cahil

In 2004, Sean Cahil, retired US Navy Chief Master-at-Arms, was aboard the USS Princeton when radar picked up extraordinary Tic Tac UFOs.

“The technology that we witnessed with the Tic Tac was something that we would not have been able to defend our forces from at the time,” Cahil said on CNN. (see video […]

New study says we’re unlikely to find liquid water on Mars anytime soon

More than a hundred years ago, astronomer Percival Lowell made the case for the existence of canals on Mars designed to redistribute water from the Martian ice caps to its lower, drier latitudes. This necessarily meant the existence of Martians to build the canals.
