Can JWST see galaxies made of primordial stars?
All stars are composed of mostly hydrogen and helium, but most stars also have measurable amounts of heavier elements, which astronomers lump into the category of "metals." Our sun has more metals than most stars because the nebula from which it form.....»»
A supernova caused the BOAT gamma ray burst, JWST data confirms
But astronomers puzzled by the lack of signatures of expected heavy elements. Enlarge / Artist's visualization of GRB 221009A showing the narrow relativistic jets—emerging from a central black hole—that gave rise to the brig.....»»
Stellar winds of three sun-like stars detected for the first time
An international research team led by a researcher from the University of Vienna has for the first time directly detected stellar winds from three sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the m.....»»
Researchers find baby stars discharge plume-like "sneezes" of magnetic flux during formation
Kyushu University researchers have shed new light into a critical question on how baby stars develop. Using the ALMA radio telescope in Chile, the team found that in its infancy, the protostellar disk that surrounds a baby star discharges plumes of d.....»»
Eclipses were once associated with the deaths of kings—predictions played a key role in the birth of astronomy
Making interesting predictions is one of the hallmarks of successful science. When Albert Einstein formulated his theory of general relativity, an almost immediate test involved the prediction that in a solar eclipse, light from stars that would norm.....»»

Hubble peers at pair of closely interacting galaxies
This image from the NASA/ESA Hubble Space Telescope features Arp 72, a very selective galaxy group that only includes two galaxies interacting due to gravity: NGC 5996 (the large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left o.....»»
Why unprotected eclipse gazing will leave you seeing stars
Just a single, unguarded glance at a solar eclipse can result in a lifetime of vision loss, eye health experts warn......»»
Researchers say neutron stars are key to understanding elusive dark matter
Scientists may be one step closer to unlocking one of the great mysteries of the universe after calculating that neutron stars might hold a key to helping us understand elusive dark matter......»»
Colin Farrell stars in new mystery drama Sugar, streaming now on Apple TV+
Colin Farrell stars in a new drama series ‘Sugar‘, streaming now on Apple TV+. Farrell plays the titular John Sugar, who is a private detective tasked with investigating the mysterious disappearance of Olivia Siegel, the daughter of a famous Holl.....»»
How NASA"s Roman Telescope will measure the ages of stars
Guessing your age might be a popular carnival game, but for astronomers it's a real challenge to determine the ages of stars. Once a star like our sun has settled into steady nuclear fusion, or the mature phase of its life, it changes little for bill.....»»
New research traces the fates of stars living near the Milky Way"s central black hole
Despite their ancient ages, some stars orbiting the Milky Way's central supermassive black hole appear deceptively youthful. But unlike humans, who might appear rejuvenated from a fresh round of collagen injections, these stars look young for a much.....»»
James Webb images capture the galactic winds of newborn stars
A stunning new pair of images from the James Webb Space Telescope show a new view of a familiar galaxy: Messier 82......»»
Student cleans up archival data and uncovers two stellar cocoons
While investigating 16 years of images of young stars from a retired astronomical camera, Leiden master's student Sam de Regt discovered that two of those stars were still enveloped in birth clouds that had not been seen at this level of detail befor.....»»
Study reports that age is the driving force in changing how stars move within galaxies
Galaxies start life with their stars rotating in an orderly pattern but in some the motion of stars is more random. Until now, scientists have been uncertain about what causes this—possibly the surrounding environment or the mass of the galaxy itse.....»»
Scientists use NASA data to predict solar corona before eclipse
Our sun, like many stars, is adorned with a crown. It's called a corona (Latin for "crown" or "wreath") and consists of long, thread-like strands of plasma billowing out from the sun's surface. The powerful magnetic field of the sun defines these str.....»»
Where are all these rogue planets coming from?
There's a population of planets that drifts through space untethered to any stars. They're called rogue planets or free-floating planets (FFPs.) Some FFPs form as loners, never having enjoyed the company of a star. But most are ejected from solar sys.....»»

Exploding stars are rare but emit torrents of radiation—one close enough to Earth could threaten life on the planet
Stars like the sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the sun shining steadily for about 5 billion more years, bu.....»»
The search for the perfect coronagraph to find Earth 2.0
Studying exoplanets is made more difficult by the light from the host star. Coronagraphs are devices that block out the star light and both JWST and Nancy Grace Roman Telescope are equipped with them. Current coronagraphs are not quite capable of see.....»»
