Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and "antimatter"—particles that are matter counterparts but with opposite charge. But then, as space expanded, the universe ...
Astronomer Carl Sagan put it best: "We're made of star stuff." The atoms that make up the chemicals of our bodies didn't originate on Earth; they came from deep space. The big bang created hydrogen, helium, and a little bit ...
Just milliseconds after the universe's Big Bang, chaos reigned. Atomic nuclei fused and broke apart in hot, frenzied motion. Incredibly strong pressure waves built up and squeezed matter so tightly together that black holes ...
In a recent study submitted to Monthly Notices of the Royal Astronomical Society, a collaborative research team has utilized the first set of data from the James Webb Space Telescope (JWST) discovering a galaxy candidate, ...
We've now seen the first data from the James Webb Space Telescope. It has observed the atmospheres of distant planets, groups of nearby galaxies, galaxy light bent by unseen dark matter, and clouds of gas and dust in stellar ...
The vast majority of stars have planets. We know that from observations of exoplanetary systems. We also know some stars don't have planets, and perhaps they never had planets. This raises an interesting question. Suppose ...
Australian scientists are making strides towards solving one of the greatest mysteries of the universe: the nature of invisible "dark matter."
A team of astronomers has developed a method that will allow them to "see" through the fog of the early universe and detect light from the first stars and galaxies.
Just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago, a scientist who analyzed the data said Wednesday.
Billions of years ago, long before a swirling cloud of gas and dust coalesced to form the sun, light left the earliest stars and began a long journey through space.
