This image from NASA's Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way's most massive globular clusters, or spherical collections of gravitationally bound stars.

An international team led by Juan Diego Soler at the University of Vienna used two of the world's most powerful radio telescopes to uncover previously hidden structures within the Orion Nebula. The project produced the sharpest maps ever made of neutral hydrogen in that region of

We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using current rocket fairings—at least as long as we're not sending them 500-plus AU away to a gravitational lensing point. We've also talked at length about th

Stars like our sun are formed from the collapse of stellar objects called prestellar cores, cold and dense concentrations of gas and dust held together by gravity. While many questions remain about the exact mechanisms of star formation, advanced radio telescopes have given resea

For the first time, scientists have used NASA's IXPE (Imaging X-ray Polarimetry Explorer) to directly measure the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the Lighthouse Nebula. The results provide new insight into the structure of s

The Euclid space telescope has spotted the oldest quasars—the brightest objects in the universe—ever discovered, deepening a cosmic mystery that has been puzzling scientists.

The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is scarce. Now, astronomers using archival data from NASA's Hubble Space Telescope and supporting obser

K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes. Advanced software analyzed millions of signals, filtering out Earth-based interference and o

This summer, Subaru Telescope will welcome a new near-infrared spectrograph, NINJA, for its first on-sky engineering observations. NINJA is a new spectrograph designed for time-critical observations of rapidly evolving cosmic events, such as the electromagnetic counterparts of gr

Astronomers have made a series of landmark observations of one of the universe's most violent events. Using the U.S. National Science Foundation Very Large Array (NSF VLA) radio telescope, which is operated by the U.S. National Science Foundation National Radio Astronomy Observat

How do black holes at the centers of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances that existed much earlier in the universe's history. New research suggests NASA's Nancy Grace Roman Spac

Blue and white stars shine brilliantly against a crimson background of glowing gas in this July 3, 2026, image of stellar nursery LH 95 from NASA's Hubble Space Telescope.
