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.....»»
Another example of a fantastic Einstein ring
The most evocative astronomy images take us across space and time to stars and galaxies billions of light-years away. Nestled at the center of this one, taken by the Hubble Space Telescope, is a collection of three galaxies. They're not all that clos.....»»
NASA scientists discover a novel galactic "fossil"

Astronomers find direct link that supernovae give rise to black holes or neutron stars
Astronomers have found a direct link between the explosive deaths of massive stars and the formation of the most compact and enigmatic objects in the universe—black holes and neutron stars. With the help of the European Southern Observatory's Very.....»»
Discovery of unusual star may change our picture of how stars explode and elements are made
Scientists have found a star unlike any other one recorded—which may change our understanding of how stars die......»»
"Stellar paternity tests" match orphaned stars to their Milky Way origins
In the chaotic environment of open star clusters, strong gravitational interactions between bodies can launch individual stars far outside the cluster, even outside our galaxy, the Milky Way. Now, for the first time researchers have mapped several of.....»»
Old stars may be the best places to search for life
Once upon a cosmic time, scientists assumed that stars apply an eternal magnetic brake, causing an endless slowdown of their rotation. With new observations and sophisticated methods, they have now peeked into a star's magnetic secrets and found that.....»»
Astronomers think they finally know origin of enormous “cosmic smoke rings“
Massive stars burn out quickly. When they die, they expel their gas as outflowing winds. Enlarge / Odd radio circles are large enough to contain galaxies in their centers and reach hundreds of thousands of light years across. (c.....»»

Unexpectedly massive black holes dominate small galaxies in the distant universe
Astronomers have discovered that the supermassive black holes in the centers of early galaxies are much more massive than expected. These surprisingly hefty black holes offer new insights into the origins of all supermassive black holes, as well as t.....»»

Study of wide binary stars reveals new evidence for modified gravity at low acceleration
A new study published in The Astrophysical Journal reveals new evidence for standard gravity breaking down in an idiosyncratic manner at low acceleration. This new study reinforces the evidence for modified gravity that was previously reported in 202.....»»
"Blob-like" home of farthest-known fast radio burst is collection of seven galaxies, researchers find
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed. And coming from a location that dates halfway back to the Big Bang, it also was the farthest known FRB spotted to date......»»
Gliese 367 b is a dark and hot sub-Earth with no atmosphere, study finds
Using the James Webb Space Telescope (JWST), astronomers have investigated a nearby sub-Earth exoplanet known as Gliese 367 b. The obtained results indicate that this alien world is dark, hot and lacks a detectable atmosphere. The new findings were p.....»»
A colossal star erupts: Examining one of the largest stars in the Milky Way as it fades from view
Astronomers from Georgia State University's CHARA Array have captured the first close-up images of a massive star known as RW Cephei that recently experienced a strange fading event. The images are providing new clues about what's happening around th.....»»
Space oddity: Uncovering the origin of the universe"s rare radio circles
It's not every day astronomers say, "What is that?" After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies. But in 2019 the newly completed ASKAP (Australian Square Kilometer Array Pathfinder) telescope pi.....»»
Scientists flip around gravitational-wave data analysis: Have LIGO and Virgo detected a merger of dark-matter stars?
Gravitational waves are ripples in the fabric of spacetime that travel at the speed of light. These are produced in some of the most violent events in the universe, such as black-hole mergers, supernovae, or the Big Bang itself. Since their first det.....»»

The most massive neutron stars probably have cores of quark matter
Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons have 2 ups and 1 down, while neutrons have 2 downs an.....»»
