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

A new Hubble image highlights the active spiral galaxy M88 and the long gravitational journey that will pull it toward the center of the Virgo Cluster.

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 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.

New research proposes an explanation for the unexpectedly massive black holes that the James Webb Space Telescope has found in the universe’s first billion years.

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 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.

A new Hubble image of NGC 3137 highlights a spiral galaxy 53 million light-years away that could help astronomers study star formation, black holes, and a galaxy group that may resemble our own.

After five years of observations, DESI has built its most detailed 3D map of the universe and added weight to the possibility that dark energy may not be constant over time.

Using data from the Dark Energy Spectroscopic Instrument, researchers have built the largest 3D map of the universe yet, giving scientists a more detailed way to trace cosmic structure and probe dark energy.

Using HETDEX data, astronomers report tens of thousands of giant hydrogen gas halos around galaxies from 10 to 12 billion years ago, offering new support for ideas about how early galaxies grew during cosmic dawn

The Dark Energy Spectroscopic Instrument has finished a five-year survey that captured more than 47 million galaxies and quasars, producing the most detailed map of the universe so far.

A new Hubble image of IC 486 highlights a barred spiral galaxy 380 million light-years away, where recent star formation and a bright active galactic nucleus coexist in the same luminous structure.

A newly reported galaxy, NGC 1052-DF9, adds to a small but consequential set of systems that appear to exist without dark matter, lending support to the controversial ‘Bullet Dwarf’ collision scenario.

A new study of more than 1 million galaxies and over 8,000 actively growing supermassive black holes points to a simple explanation for the modern slowdown in black hole growth: not enough cold gas.

Astronomers have directly measured superheated gas blasting out of the starburst galaxy M82 at more than 3.2 million kilometers per hour, strengthening the case for a stellar-driven outflow.

NASA and JAXA’s XRISM mission has directly measured the speed of superheated gas blasting out of the starburst galaxy M82, offering fresh evidence about what drives galaxy-scale winds.

A massive international collaboration using the James Webb Space Telescope and ALMA has identified 70 dusty galaxies from the universe's first billion years. These ancient objects appear to have formed stars far earlier than current models predict, potentially forcing a fundamental reassessment of how galaxies evolve.
