When astronomers discovered a giant planet orbiting a dead star in 2020, they wondered how it survived its star’s violent demise. Now, observations from NASA’s James Webb Space Telescope (JWST) may finally explain the planet’s unlikely escape from destruction.

Millions of stars. Thousands of hidden worlds. One unprecedented view of our galaxy. Three years since launch, ESA’s Euclid space telescope reveals the center of the Milky Way galaxy in extraordinary detail: a mosaic of tens of millions of stars captured in just 26 hours. But this is more than an image. It is a […]

Research has shed new light on why some distant galaxies suddenly stop forming stars. An international team led by astronomers at the University of Nottingham has used the James Webb Space Telescope to study a large sample of recently “quenched” galaxies in the distant universe, observed around nine billion years ago. Their findings appear in […]

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 […]

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 […]
