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.....»»
Potential indicators of life on other planets can be created in a lab
One way to understand the potential for life on far-off planets—those in other solar systems that orbit different stars—is to study a planet's atmosphere. Telescopic images often capture traces of gases that may indicate life and habitable planet.....»»
We gave the MacBook Air (M3) four stars — It’s on sale right now
B&H has cut the price of the highly popular Apple MacBook Air M3. Here's why you need it in your life......»»
Observations confirm that early-universe quasar neighborhoods are densely populated with companion galaxies
Quasars are the most luminous objects in the universe and are powered by material accreting onto supermassive black holes at the centers of galaxies......»»
Could stars hotter than the sun still support life?
Although most potentially habitable worlds orbit red dwarf stars, we know larger and brighter stars can harbor life. One yellow dwarf star, for example, is known to have a planet teaming with life, perhaps even intelligent life. But how large and bri.....»»
Giant panda skin cells transformed into stem cells to help ensure their survival
A team of biologists in China has reprogrammed skin cells from giant pandas into induced pluripotent stem cells (iPSCs), opening the door to creating primordial germ cells that could serve as precursors to sperm and egg cells......»»

Exoplanets could be hiding their atmospheres
Most of the exoplanets we've discovered orbit red dwarf stars. This isn't because red dwarfs are somehow special, simply that they are common. About 75% of the stars in the Milky Way are red dwarfs, so you would expect red dwarf planets to be the mos.....»»
Citizen science collaboration yields precise data on exoplanet WASP-77 A b
A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets—planets around stars other than the sun. But predicting when these special events occur.....»»
Scientists scan TRAPPIST-1 for technosignatures
If you are going to look for intelligent life beyond Earth, there are few better candidates than the TRAPPIST-1 star system. It isn't a perfect choice. Red dwarf stars like TRAPPIST-1 are notorious for emitting flares and hard X-rays in their youth,.....»»
New cosmic distance catalog could unlock the mysteries of universe formation
A new catalog providing information on millions of distant galaxies, which determines their distances with unprecedented precision over a field of view and depth never before explored, has been published today......»»
Magnifying deep space through the "Carousel Lens"—rare alignment offers unique opportunity to study cosmology
In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The Carousel Lens is a massive cluster-scale gravitational lens system that.....»»
James Webb image shows two galaxies in the process of colliding
A new image from the James Webb Space Telescope captures one of the universe's most dramatic events: the colliding of two galaxies......»»

Astronomers detect black hole "starving" its host galaxy to death
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars. The results are reported in the journal Nature Astronomy......»»

Experimental data help unravel the mystery surrounding the creation of heavy elements in stars
How are stars born, and how do they die? How do they produce the energy that keeps them burning for billions of years? How do they create the elements we observe today? Definitive answers to these questions continue to elude scientists in their quest.....»»
Combination and summary of ATLAS dark matter searches within 2HDM+a framework
In the 1930s, Swiss astronomer Fritz Zwicky observed that the velocities of galaxies in the Coma Cluster were too high to be maintained solely by the gravitational pull of luminous matter. He proposed the existence of some non-luminous matter within.....»»
Image: James Webb Space Telescope observes nearby star-forming region NGC 1333 in infrared
NASA's James Webb Space Telescope has infrared vision that lets us peer through the dusty veil of nearby star-forming region NGC 1333. We can see planetary mass objects, newborn stars, and brown dwarfs; some of the faintest "stars" in this mosaic ima.....»»
Formation of super-Earths proven 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 stars......»»
