Radio Signal From the Most Distant Galaxy Captured by Astronomers

A radio signal has been picked up by astronomers from the most distant galaxy known to mankind with a unique wavelength known as the "21-centimeter line" or the "hydrogen line," emitted by neutral hydrogen atoms. The Giant Metrewave Radio Telescope...

NASA Unveils Plan for New Telescope to Find Life on Alien Worlds

Future discoveries are often on the minds of astronomers. Researchers at this week's American Astronomical Society meeting filled a conference room to capacity to hear about plans for a successor to the James Webb Space Telescope (JWST) that began operations...

Astronomers Find the Most Distant Stars in Our Galaxy

More than 200 RR Lyrae stars—distant variable stars—have been found by astronomers in the Milky Way's stellar halo. Over a million light-years separate us from the furthest of these stars. This is roughly half the distance to our nearest...

The Most Powerful Explosion in Universe Gives Birth to Black Hole

Astronomers observed the most powerful explosion ever recorded in the universe, which gave birth to a black hole. They did so using the Gemini South telescope in Chile operated by NSF's NOIRLab. Dubbed Gamma-Ray Burst GRB221009A, this record-shattering the observed...

A Protogalaxy in the Milky Way May Be Our Galaxy’s Original Nucleus

Astronomers have identified a protogalaxy in the Milky Way in and around the constellation Sagittarius which suggests it may be our galaxy’s original nucleus. New data from the Gaia spacecraft reveal the full extent of what seems to be the...

Jupiter’s Orbit Change Could Make Earth Even More Hospitable to Life

According to recent research, a change in Jupiter's orbit might make the surface of Earth even more suitable to life than it already is. Scientists at the University of California-Riverside (UCR) studied simulations of several configurations of our solar system...

Oldest Dark Matter in the Universe Detected by Scientists

Scientists have detected the distribution of the oldest dark matter ever observed in the universe based on calculations from the glow of surrounding galaxies of twelve billion years ago. The history of our entire universe is smeared across the vastness...

Mysterious Heartbeat Radio Burst Discovered in Space

Astronomers have detected a mysterious fast radio burst in space with a pattern similar to a heartbeat with a signal estimated to come from a faraway galaxy roughly a billion light-years away. In a study detailing the findings published in...
