Astronomers using James Webb data have reconstructed the cosmic web at a new level of detail, offering a clearer picture of how galaxies formed and evolved across deep time.

A new combined view of the Whirlpool Galaxy is helping astronomers study how newly formed stars clear away surrounding gas and dust, a key process in galaxy evolution.

NASA’s Nancy Grace Roman Space Telescope is reportedly ahead of schedule and under budget, with a September launch expected. Meanwhile, Hubble has already surveyed part of Roman’s future hunting ground in the Milky Way’s

Researchers analyzing Antarctic ice cores found changing levels of iron-60 over the last 80,000 years, strengthening the case that Earth is currently being dusted by material preserved in the Local Interstellar Cloud.

A waxing crescent Moon will pass near Venus and Jupiter on consecutive evenings in mid-May, creating one of 2026’s most accessible dusk sky events for casual observers and telescope users alike.

A new Hubble image spotlights NGC 1266, a lenticular galaxy about 100 million light-years away that astronomers describe as a rare post-starburst system in transition.

The Moon is down to a 4% waning crescent on May 15, setting up the final approach to the New Moon and an unusual month with two Full Moons before May ends.

NASA’s exoplanet-hunting TESS mission has released a new all-sky mosaic that maps nearly 700 confirmed worlds and more than 5,000 candidate planets across observations gathered through September 2025.

Asteroid 2026JH2, estimated at 16 to 36 meters across, is expected to pass Earth at about 90,917 kilometers on May 18, a close approach that astronomers say is dramatic but not dangerous.

New research argues that exceptionally powerful quasars in the early universe frequently drove galaxy-scale outflows strong enough to strip star-forming gas and help create the quiescent galaxies seen by JWST.

A five-year review of ESA’s 24/7 impact-monitoring system says MeerKAT successfully warned of all seven imminent impactors detected in advance, underscoring how planetary defense is shifting toward faster automated alert

New James Webb Space Telescope observations of the planetary nebula Tc 1 are giving astronomers a sharper view of where buckminsterfullerene, or C60, emerges in space and how complex carbon chemistry develops around dead

A newly identified X-ray bright object in the young universe could offer astronomers a missing link in the debate over what JWST’s mysterious little red dots really are.

The Moon enters a waning crescent phase on May 10, with nearly half its surface illuminated and several well-known lunar features still visible for observers on Earth.

A new analysis of black hole mergers in the LIGO-Virgo-KAGRA catalog points to a separate population of very massive, rapidly spinning black holes formed through hierarchical mergers.

Astronomers studying the interstellar comet 3I/ATLAS say its water contains an unusually high concentration of deuterium, offering a rare look at how planetary systems may form in colder environments than our own.

Observations of interstellar comet 3I/ATLAS after perihelion found a lower carbon-dioxide-to-water ratio than earlier space-based observations suggested, pointing to changing coma chemistry and a more layered interior.

Using 18 years of radio observations, researchers studying Cygnus X-1 have measured the immense power of its black hole jets and estimated their speed at roughly half the speed of light.

A new study suggests NASA’s Nancy Grace Roman Space Telescope may be able to identify and measure isolated neutron stars through astrometric microlensing, exposing objects that are otherwise nearly impossible to detect.

Volunteers working through NASA’s Backyard Worlds: Planet 9 project have identified more than 3,000 new brown dwarfs over a decade, dramatically expanding one of astronomy’s most elusive catalogs.
