Are Andromeda and the Milky Way doomed to collide? Maybe not
Scientists discovered the Andromeda galaxy, known as M31, hundreds of years ago, and around a century ago, we realized that it had negative radial velocity toward the Milky Way. In other words, eventually, the two galaxies would merge spectacularly......»»
Astronomers use AI to find elusive stars "gobbling up" planets
Astronomers have recently found hundreds of "polluted" white dwarf stars in our home galaxy, the Milky Way. These are white dwarfs caught actively consuming planets in their orbit. They are a valuable resource for studying the interiors of these dist.....»»
Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»
DART mission sheds new light on target binary asteroid system
In studying data collected from NASA's DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission's science team has discovered new information on the ori.....»»
Uncovering Magnetism’s Mysterious Role in the Galaxy
Susan Clark is helping to unravel the mysterious workings of the Milky Way’s magnetic field, a critical missing piece of the galactic puzzle......»»
Saturday Citations: Scientists study monkey faces and cat bellies; another intermediate black hole in the Milky Way
This is not a rerun of last week's roundup; another group of astronomers found a second intermediate-mass black hole in the Milky Way and I can't avoid highlighting it. They're cool! They may have formed in the primordial universe, they comprise the.....»»
Double trouble: Gaia hit by micrometeoroid and solar storm
Launched in December 2013, ESA's Gaia spacecraft is on a mission to map the locations and motions of more than a billion stars in the Milky Way with extreme precision......»»
Telescope tag-team discovers 10 strange and exotic pulsars
Towards the center of our Milky Way galaxy, in the constellation Sagittarius, astronomers have discovered 10 monstrous neutron stars. These particular stars, called pulsars, reside together in globular cluster Terzan 5, a crowded home for hundreds of.....»»
Observatory gears up to detect thousands of elusive brown dwarfs, unlocking Milky Way mysteries
One could argue that brown dwarfs don't get the love they deserve. Sometimes referred to as "failed stars," they don't have enough mass to sustain nuclear fusion, which powers all stars, including our sun. But they are also too big to be considered p.....»»
Researchers directly simulate the fusion of oxygen and carbon nuclei
The fusion of two nuclei is a complex process influenced by many factors. These factors include not only the relative energy and angular momentum of the two nuclei, but also how their structures evolve as they collide. The outcome of the collisions i.....»»
Webb unveils stunning ejecta and CO structures in Cassiopeia A"s young supernova
The SETI Institute announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the co.....»»
SpaceX rocket accident leaves company"s Starlink satellites in wrong orbit
A SpaceX rocket has failed for the first time in nearly a decade, leaving the company's internet satellites in an orbit so low that they're doomed to fall through the atmosphere and burn up......»»
How astronomers work out the size of the solar system
The size of the solar system is defined by the volume of space over which the sun's influence exceeds those of other nearby stars in the Milky Way galaxy. This influence derives from two fundamental forces of nature: gravity and magnetism......»»
Swarm of dusty young stars found around our galaxy’s central black hole
Stars shouldn't form that close to the black hole, so these would need explaining. Enlarge / The Milky Way's central black hole is in a very crowded neighborhood. (credit: UMass/D.Wang/NASA/STScI) Supermassive black hole.....»»
New models suggest Milky Way is not as packed with stars as previously thought
A small team of astronomers from Yunnan University, the University of Utah, New Mexico State University, and the University of St Andrews has created a new model of the Milky Way galaxy based on the results of their census of red giants......»»

Euclid space telescope unveils new images of the cosmos
A mind-boggling number of shining galaxies, a purple and orange star nursery and a spiral galaxy similar to our Milky Way: new images were revealed from Europe's Euclid space telescope on Thursday......»»
Humane AI Pin is a disaster: Founders already want to sell the company
One month after launch of its "smartphone replacement," Humane already seems doomed. Enlarge / The Humane AI Pin. It has a magnetic back, so it sticks to your clothing like a name tag. (credit: Humane) The wearable sta.....»»
Scientists demonstrate the survival of quantum coherence in a chemical reaction involving ultracold molecules
If you zoom in on a chemical reaction to the quantum level, you'll notice that particles behave like waves that can ripple and collide. Scientists have long sought to understand quantum coherence, the ability of particles to maintain phase relationsh.....»»
Smashing into an asteroid shows researchers how to better protect Earth
Slowing down an asteroid by just one-tenth of a second makes all the difference. Enlarge / Riding atop a SpaceX Falcon 9 rocket, NASA’s Double Asteroid Redirection Test, or DART, spacecraft sets off to collide with an asteroid.....»»
