New view of North Star reveals spotted surface
High-resolution images show large spots on the surface of Polaris.
View ArticleExtraterrestrial chemistry with earthbound possibilities
Who are we? Why are we here? We are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas and dust. To better understand how that chemistry could create prebiotic...
View ArticleNASA's DART impact permanently changed the shape and orbit of asteroid moon
A new study provides insights on the geophysics behind asteroid formation and evolution.
View ArticleEarly galaxies were not too big for their britches after all
According to a new study, some of the earliest galaxies observed with the James Webb Space Telescope are in fact much less massive than they first appeared. Black holes in some of these galaxies make...
View ArticleSix new rogue worlds: Star birth clues
The James Webb Space Telescope has spotted six likely rogue worlds -- objects with planet-like masses but untethered from any star's gravity -- including the lightest ever identified with a dusty disk...
View ArticleHidden magmatism discovered at the Chang'e-6 lunar landing site
Lunar igneous activities including intrusive and extrusive magmatism, and their products contain significant information about the lunar interior and its thermal state. Their distribution is...
View ArticleHighest-resolution observations yet from the surface of Earth
Astronomers have achieved the highest resolution ever obtained from the surface of Earth. They managed this feat by detecting light from distant galaxies at a frequency of around 345 GHz, equivalent to...
View ArticleDark matter could have helped make supermassive black holes in the early...
Supermassive black holes typically take billions of years to form. But the James Webb Space Telescope is finding them not that long after the Big Bang -- before they should have had time to form....
View ArticleDancing galaxies make a monster at the cosmic dawn
Astronomers have spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the brightest...
View ArticleSupercomputer simulations reveal the nature of turbulence in black hole...
To understand the mysteries surrounding black holes, researchers at Tohoku University have created a simulation of accretion disk turbulence that possesses the highest-resolution currently available.
View ArticleHow bright is the universe's glow? Study offers best measurement yet
Over billions of years, the universe's stars and galaxies shined their light into space, leaving behind an imperceptibly faint night light known as the cosmic optical background. NASA's New Horizons...
View ArticleGigantic asteroid impact shifted the axis of Solar System's biggest moon
Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a researcher realized that the Solar System's biggest moon's axis has shifted as a result of the impact, which confirmed that...
View ArticleDistorted galaxy forming cosmic question mark
It's 7 billion years ago, and the universe's heyday of star formation is beginning to slow. What might our Milky Way galaxy have looked like at that time? Astronomers have found clues in the form of a...
View ArticleResearchers discover a space oddity -- an exoplanet moving in mysterious ways
A research team has discovered a small planet that displays peculiar orbital motion. The shimmying planet, located 455 light-years from Earth, shows that planetary systems can be considerably more...
View ArticleMassive merger: Study reveals evidence for origin of supermassive black hole...
Researchers have discovered compelling evidence suggesting that the supermassive black hole at the center of our Milky Way galaxy, known as Sagittarius A* (Sgr A*), is likely the result of a past...
View ArticleAstrophysics: AI shines a new light on exoplanets
A team models the atmospheres of distant planets using neural networks.
View ArticleFormation of super-Earths is limited near metal-poor stars
In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity...
View ArticleAstronomers track bubbles on star's surface in most detailed video yet
Astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained in July and August...
View ArticleMagnetic field maps of the sun's corona
Astronomers have achieved a major breakthrough in solar physics by successfully producing detailed maps of the Sun's coronal magnetic fields. This milestone promises to enhance our understanding of the...
View ArticleNASA's Webb peers into the extreme outer galaxy
Astronomers have directed NASA's James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000...
