Hubble captures a formation of galaxies neatly lined up
A new Hubble image shows both an interacting galaxy system, and a string of galaxies which happen to line up in a neat procession......»»
What would happen to Earth if a rogue star came too close?
Stars are gravitationally fastened to their galaxies and move in concert with their surroundings. But sometimes, something breaks the bond. If a star gets too close to a supermassive black hole, for example, the black hole can expel it out into space.....»»
Dark matter could help solve the final parsec problem of black holes
When galaxies collide, their supermassive black holes enter into a gravitational dance, gradually orbiting each other ever closer until eventually merging. We know they merge because we see the gravitational beasts that result, and we have detected t.....»»
Where are all the double planets?
A recent study published in the Monthly Notices of the Royal Astronomical Society examines formation mechanisms for how binary planets—two large planetary bodies orbiting each other—can be produced from a type of tidal heating known as tidal diss.....»»
The formation of an excitonic Mott insulator state in a moiré superlattice
When a negatively charged electron and a positively charged hole in a pair remain bound together following excitation by light, they produce states known as excitons. These states can influence the optical properties of materials, in turn enabling th.....»»

A radically new view on dwarf galaxies surrounding the Milky Way
Commonly thought to be long-lived satellites of our galaxy, a new study now finds indications that most dwarf galaxies might, in fact, be destroyed soon after their entry into the Galactic halo......»»
Dwarf galaxies use 10-million-year quiet period to churn out stars
If you look at massive galaxies teeming with stars, you might be forgiven for thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of.....»»
The formation of switchable and metastable discrete structures through chiral self-sorting
A paper titled "Thermo-/Mechano-Chromic Chiral Coordination Dimer: Formation of Switchable and Metastable Discrete Structure through Chiral Self-Sorting" describes chiral coordination dimers that emerge based on effectively exclusive chiral self-sort.....»»
"Teenage galaxies" are unusually hot, glowing with unexpected elements
Similar to human teenagers, teenage galaxies are awkward, experience growth spurts and enjoy heavy metal—nickel, that is......»»
Physicists answer question of Supergalactic Plane"s absent spiral galaxies
Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our local universe called the Supergalactic Plane......»»
Hubble spots an Earth-sized exoplanet just 22 light-years away
The Hubble Space Telescope has recently confirmed that a nearby planet, which is diminutive by exoplanet standards, is 1.07 times the size of Earth......»»
Hubble images NGC 941, a spiral galaxy with an explosive past
This image from NASA's Hubble Space Telescope features the spiral galaxy NGC 941, which lies about 55 million light-years from Earth. Hubble's Advanced Camera for Surveys (ACS) collected the data that created this image. Beautiful NGC 941 is undoubte.....»»
Study reveals wintertime formation of large pollution particles in China"s skies
School of Earth and Atmospheric Sciences researchers find dangerous sulfates are formed, and their particles get bigger, within the plumes of pollution belching from coal-fired power plants.....»»
ALMA observation of young star reveals details of dust grains
One of the primary goals of the Atacama Large Millimeter/submillimeter Array (ALMA) is to study the formation and evolution of planetary systems. Young stars are often surrounded by a disk of gas and dust, out of which planets can form......»»
Webb follows neon signs toward new thinking on planet formation
Scientists are following neon signs in a search for clues to one planetary system's future and the past of another—our own solar system. Following up on a peculiar reading by NASA's previous infrared flagship observatory, the now-retired Spitzer Sp.....»»
The universe is expanding faster than theory predicts—physicists are trying to explain the mismatch
Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth......»»
The "Cosmic Vine": Astronomers discover a large structure that hosts at least 20 massive galaxies
An international team of astronomers reports the discovery of a large-scale structure that consists of at least 20 massive galaxies. The structure, dubbed "Cosmic Vine," has a size of about 13 million physical light years. The finding was detailed in.....»»
Study resolves puzzles in gravitational collapse of gravitational waves
Black holes are regions in space where the gravitational pull is so strong that nothing can escape them, not even light. These fascinating regions have been the focus of countless studies, yet some of the physics underlying their formation is not yet.....»»
