NASA has completed final inspection of the Nancy Grace Roman Space Telescope’s primary mirror, clearing a major milestone before shipment and launch.

Observations of TOI-199b with the James Webb Space Telescope identified methane in the atmosphere of a cooler gas giant, supporting long-standing models.

Astronomers using the James Webb Space Telescope and gravitational lensing have identified LAP1-B as the most metal-poor early-universe galaxy yet observed, offering a rare look at conditions about 800 million years from

NASA engineers completed the final inspection of the Nancy Grace Roman Space Telescope’s 2.4-meter primary mirror, keeping the mission on track for an early September launch.

NASA says the Nancy Grace Roman Space Telescope could reveal around 100,000 worlds, expanding exoplanet searches far beyond the solar neighborhood.

The method uses strong gravitational-wave signals and relativity-based expectations to recalibrate detector data after the fact, potentially improving measurement quality.

A one-hour brightening in the Large Magellanic Cloud may mark one of the smallest gravitational lenses ever detected, with implications for rogue planets and primordial black holes.

A rare fireball meteor flashed over the erupting Mount Mayon in the Philippines, and experts quickly moved to correct false reports that it struck the volcano.

Using the James Webb Space Telescope and gravitational lensing, astronomers characterized the ultra-faint galaxy LAP1-B and identified it as the most metal-poor galaxy yet observed in the early universe.

New James Webb Space Telescope analysis suggests the extreme infrared output of W2246−0526, the most distant known Hot DOG, may be explained in part by polar dust rather than the torus alone.

A new installment in Universe Today’s SETI history series revisits the idea that technological civilizations may not stay detectable for long, limiting the odds of overlap and contact.

New research argues that active galactic nuclei can strip atmospheres and damage ozone far from a galaxy’s center, widening the map of what makes a world uninhabitable.

The Moon reaches its First Quarter phase on May 23, with about 48% of the visible face illuminated, offering an easy night-sky marker for where the current lunar cycle stands.

A James Webb Space Telescope study of four nearby galaxies found that more massive star clusters break out of their birth clouds faster, adding new detail to how star formation shapes galaxies.

A routine moon-phase explainer for May 22 illustrates how astronomy content is increasingly packaged as daily habit media, blending accessible skywatching with evergreen search demand.

A review of Celestron’s AstroMaster LT 70AZ shows how entry-level telescopes can lower the barrier to astronomy while also exposing the compromises in stability, control, and long-term capability that come with budget ge

A new essay from Universe Today revisits one of space science’s most irritating materials, arguing that the same dust that clogs missions, coats equipment, and threatens health is also fundamental to how the cosmos works

Researchers using NASA’s TESS mission say they have identified 27 new candidate planets orbiting binary star systems, using a detection method designed to find worlds that standard transit searches can miss.

Astronomers using TESS data and a detection technique based on apsidal precession say they have uncovered 27 new circumbinary planet candidates, potentially expanding one of exoplanet science’s rarest classes.

Astronomers used a decade of observations of a distant blazar to show that turbulence in the Milky Way’s interstellar medium adds its own distortions to radio signals from deep space.
