We could detect a malfunctioning warp drive on an alien starship
Faster-than-light warp drives are theoretically possible to build, and if aliens are using them, we should be able to detect the gravitational waves produced when one goes wrong

James Webb Space Telescope finds possible evidence of dark stars
A trio of astrophysicists, two from Colgate University and the third from the University of Texas, has found evidence of dark stars courtesy of data from the James Webb Space Telescope. In their study, reported in Proceedings of the National Academy of Sciences, Cosmin Ilie, Jillian Paulin and Katherine Freese, analyzed three galaxies spotted by the JWST and how they might relate to dark stars.

Seven Amazing Accomplishments the James Webb Telescope Achieved in Its First Year
The James Webb Space Telescope, the largest and most sophisticated space observatory ever built, has been sending back images and data for almost a full year now—and in that time it has delivered a treasure trove of information about everything from stars and planetary systems in our own galactic neighborhood to distant galaxies that formed when the universe was a tiny fraction of its current age.

The expansion of the universe could be a mirage, new theoretical study suggests
The expansion of the universe could be a mirage, a potentially controversial new study suggests. This rethinking of the cosmos also suggests solutions for the puzzles of dark energy and dark matter, which scientists believe account for around 95% of the universe's total energy and matter but remain shrouded in mystery.

Missing Stars Puzzle Astronomers: Could Intelligent Life Be the Cause?
Over a period of 70 years, thousands of stars have vanished from the sky; Which prompted a team of astronomers to shed light on this phenomenon .. and perhaps a (very weak) hope of uncovering traces of intelligent civilizations outside the planet.

Galaxies spotted by Webb telescope rewrite understanding of early universe
Observations by NASA's James Webb Space Telescope are upending the understanding of the early universe, indicating the presence of large and mature but remarkably compact galaxies teeming with stars far sooner than scientists had considered possible.

Supermassive black hole at heart of ancient galaxy ‘far larger than expected’
A supermassive black hole discovered at the heart of an ancient galaxy is five times larger than expected for the number of stars it contains, astronomers say. Researchers spotted the immense black hole in a galaxy known as GS-9209 that lies 25bn light-years from Earth, making it one of the most distant to have been observed and recorded.

Betelguese’s Brightening Raises Hopes for a Supernova Spectacle
Even if you don’t know it by name, the red supergiant star Betelgeuse is one of the most familiar sights in the heavens above—a gleaming ruddy dot at the shoulder of the constellation Orion. Although already quite difficult to overlook, Betelgeuse has become even more eye-catching across the past few years because of major changes in its appearance—unexpected fluctuations in its brightness that remain poorly understood. In recent weeks, the star has at times shone more than 50 percent brighter than normal, drawing renewed attention from amateur sky watchers and professional astronomers alike.

Astronomers spot the biggest cosmic explosion ever seen, and it's 100 times the size of our solar system
The blast, which is 2 trillion times brighter than the sun, may have been caused by a supermassive black hole sending shock waves through a cloud of cosmic gas.

Webb telescope discovers oldest galaxies ever observed
The James Webb Space Telescope has discovered the four most distant galaxies ever observed, one of which formed just 320 million years after the Big Bang when the universe was still in its infancy, new research said on Tuesday.

Galaxy clusters yield new evidence for standard model of cosmology
Cosmologists have found new evidence for the standard model of cosmology—this time, using data on the structure of galaxy clusters. In a recent study published in Monthly Notices of the Royal Astronomical Society, a team led by physicists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University made detailed measurements of the X-ray emission from galaxy clusters, which revealed the distribution of matter within them. In turn, the data helped the scientists test the prevailing theory of the structure and evolution of the universe, known as Lambda-CDM.

How high-altitude balloons help unlock the cosmos
The recent episodes of jet fighters shooting down spy balloons has everyone talking about how they can be used for surveillance. But if anyone had bothered to ask an astronomer, they would know we’ve been attaching telescopes to balloons for decades — and the technique even represents the latest cutting edge in NASA research.

James Webb Telescope discovers six massive 'universe breaker' galaxies
Astronomers have detected what appear to be six massive and very ancient galaxies, a discovery they say could upend our understanding of how galaxies formed at the very beginning of the universe. While the new James Webb Space Telescope has already spotted even older galaxies, it’s the size and maturity of these six apparent mega-galaxies that have stunned scientists.

All of Jupiter's Large Moons Have Auroras
Jupiter is well known for its spectacular aurorae, thanks in no small part to the Juno orbiter and recent images taken by the James Webb Space Telescope (JWST). Like Earth, these dazzling displays result from charged solar particles interacting with Jupiter’s magnetic field and atmosphere. Over the years, astronomers have also detected faint aurorae in the atmospheres of Jupiter’s largest moons (aka. the “Galilean Moons“). These are also the result of interaction, in this case, between Jupiter’s magnetic field and particles emanating from the moons’ atmospheres.

Black holes may be the source of mysterious dark energy
When astronomers discovered that the universe is expanding at an accelerating rate, they theorized that some force must be pushing things farther apart and overcoming gravity, which should be slowing things down. That force was suggested to be dark energy, but no one has ever figured out from where it comes.
