Scientists find evidence for magnetic reconnection between Ganymede and Jupiter: Juno spacecraft discovered magnetospheric fireworks as magnetic field lines merge and snap between the gas giant and its largest moon

In June 2021, NASA’s Juno spacecraft flew close to Ganymede, Jupiter’s largest moon, observing evidence of magnetic reconnection. A team led by Southwest Research Institute used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and…

Cat locomotion could unlock better human spinal cord injury treatment

Cats always land on their feet, but what makes them so agile? Their unique sense of balance has more in common with humans than it may appear. Researchers at the Georgia Institute of Technology are studying cat locomotion to better understand how the spinal cord works to help humans with…

Astronomers find the most distant stars in our galaxy halfway to Andromeda: A search for variable stars called RR Lyrae has found some of the most distant stars in the Milky Way’s halo a million light years away

Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way’s stellar halo. The most distant of these stars is more than a million light years from Earth, almost half the distance to our neighboring galaxy, Andromeda, which is about 2.5 million light…

Hydrogen masers reveal new secrets of a massive star: Scientists used the unique hydrogen radio recombination lines on MWC 349A to reveal hidden collimated jets

While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star’s gas disk at impossibly high speeds. What’s more, they believe the jet is caused by strong magnetic forces surrounding…

Scientists find pair of black holes dining together in nearby galaxy merger

While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA) — an international observatory co-operated by the U.S. National Science Foundation’s National Radio Astronomy Observatory (NRAO) — scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry…

NASA’s retired Compton mission reveals superheavy neutron stars

Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into a black hole. This fleeting, massive object likely formed from the collision of two neutron stars. “We looked for these…

Galactic shock is shaping Stephan’s Quintet in mysterious ways

Shockwaves resulting from the violent collision between an intruder galaxy and Stephan’s Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST) have revealed that a sonic boom several times…

‘Smart’ coating can be precisely applied to make fabric into protective gear: Metal-organic technology detects and captures toxic gases in air, researchers report

A durable copper-based coating developed by Dartmouth College researchers can be precisely integrated into fabric to create responsive and reusable materials such as protective equipment, environmental sensors, and smart filters, according to a recent study. The coating responds to the presence of toxic gases in the air by converting them…

Searching for the earliest galaxies in the universe

In a new study, a team of astronomers led by Haojing Yan at the University of Missouriused data from NASA’s James Webb Space Telescope (JWST) Early Release Observations and discovered 87 galaxies that could be the earliest known galaxies in the universe. The finding moves the astronomers one step closer…
