Imagine standing in the emptiest place the universe has to offer, a stretch of cosmic ocean so vast that light takes tens of millions of years to cross it, and yet still finding company. That is the puzzle behind a new study built on the Calar Alto Void Integral field Treasury surveY, or CAVITY, posted […]
NASA on Tuesday announced new uncrewed missions to aid in the future creation of a lunar surface base, a project beginning to take shape despite recent setbacks.

On Jan. 26, 2026, the Submillimeter Array (SMA) on Maunakea crossed an important threshold for time-domain astronomy. For the first time, scientists from the Center for Astrophysics | Harvard & Smithsonian (CfA) demonstrated a new rapid-response capability at millimeter and submillimeter wavelengths, zooming in on a gamma-ray burst (GRB) within minutes of its discovery and […]
Hopefully, we’re about to travel back to the moon relatively soon. And while the original “giant leap for mankind” was taken by a human, Neil Armstrong brought a plethora of other forms of life along with him. Humans themselves are essentially walking ecosystems, and understanding how our microbial companions survive in the harsh environments of […]
Astronomers have, for the first time, found a source in the process of becoming a Little Red Dot, using the James Webb Space Telescope (JWST). Little Red Dots are likely early galaxies and some of the most intriguing objects found with JWST at high redshifts. The team, led by Karina Caputi of the University of […]
In celebration of the 250th birthday of the United States, NASA has unveiled four cosmic images from its Chandra X-ray Observatory, rendered in red, white and blue, that represent the wonders of the universe the agency explores. The images are accompanied by a trio of new sonifications—a technique that translates astronomical data into sound.

When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something else: low-frequency sound waves that traveled hundreds of miles and were captured by a dense network of earthquake and volcano-monitoring sensors […]
Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.

Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits a small, cool star called a red dwarf. Just 25 light-years from Earth in the direction of the northern constellation Camelopardalis, […]
The largest digital camera ever built is starting to capture images of unseen corners of the universe.

Peering far into the distant, high-redshift universe, the James Webb telescope has discovered an abundance of small red galaxies known as the Little Red Dots. From their observations, astronomers believe that at least some of these galaxies may be home to growing supermassive black holes at their centers, objects which they believe are embedded in […]
Securing sustainable food supplies is a key challenge for long-term human exploration and potential habitation of the moon. The moon’s soil contains no organic material, and essential plant nitrogen sources like ammonia and nitrate are virtually nonexistent.

Indonesian astronomers have conducted a comprehensive study of an open cluster in the constellation Norma, known as NGC 6134. Results of the new study, available in a research paper published June 23 on the preprint server arXiv, deliver important insights into the properties and nature of this cluster.
