If you look at massive galaxies teeming with stars, you might be forgiven for thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, ...
NASA's Nancy Grace Roman Space Telescope will pair space-based observations with a broad field of view to unveil the dynamic cosmos in ways that have never been possible before.
The second- and fourth-most distant galaxies ever observed have been discovered in a region of space known as Pandora's Cluster, or Abell 2744, using data from NASA's James Webb Space Telescope (JWST).
Scientists have discovered the oldest black hole yet, a cosmic beast formed a mere 470 million years after the Big Bang.
Since it became operational almost two years ago, the James Webb Space Telescope (JWST) has produced countless breathtaking images of the universe and enabled fresh insights into how it evolved.
Since Mercury is the closest planet to the sun among the solar system planets, it is strongly influenced by the solar wind, a high-speed (several hundred km/s) stream of plasma blowing from the sun. Explorations of Mercury ...
When scientists viewed the James Webb Space Telescope's (JWST) first images of the universe's earliest galaxies, they were shocked. The young galaxies appeared too bright, too massive and too mature to have formed so soon ...
In recent years, astronomy has seen itself in a bit of crisis: Although we know that the universe expands, and although we know approximately how fast, the two primary ways to measure this expansion do not agree. Now astrophysicists ...
There are unexplored regions of the universe—and there are also unexplored times. In fact, there's a nearly 400-million-year gap in our universe's history that we've never seen: a time before stars known as the Dark Ages. ...
With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history ...
