Astronomers have found a candidate Jellyfish Galaxy only about 5 billion years after the Big Bang. This is earlier than expected, since the ram pressure stripping responsible for it wasn’t

The early Universe was a busy place. As the infant cosmos exanded, that epoch saw the massive first stars forming, along with protogalaxies. It turns out those extremely massive early
Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University researchers now have evidence of the surprisingly simple process that
We know galaxies by their powerful illumination, generated by multitudes of stars. But some galaxies can be very dim. These are hypothesized to be dark galaxies, or dark matter galaxies.
In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible—low-surface-brightness galaxies dominated by dark matter
Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable
Just a few hundred light-years from Earth, the famous variable star Mira A is huffing and puffing its outer layers to space. Its most recent mass-loss event ejected more material
Imagine you’re all alone, driving along in a rocky, unforgiving desert with no roads, no map, no GPS, and no more than one phone call a day for someone to
There’s been plenty in the news about 3I/ATLAS over the course of the past 8 months. Our third confirmed interstellar visitor went behind the Sun during its closest approach, but
We know that supermassive black holes can inhibit star formation in their galaxies. But new research and JWST observations show that the most luminous quasars can actually suppress star formation
