(The following is an open letter to Greater New Milford-area residents from the volunteers at the McCarthy Observatory on the campus of New Milford High School.) Dear friends of the McCarthy ...

Using spectral data from the Hobby-Eberly Telescope at McDonald Observatory, astronomers have produced the most detailed 3D map yet of faint cosmic structures from 9-11 billion years ago, revealing ...

Astronomers utilizing the James Webb Space Telescope (JWST) have identified a supermassive black hole, dating back to the universe's "cosmic noon" — an epoch occurring approximately 4 billion years ...

Astronomers have announced a candidate for the universe's first generation of stars. While sifting through observations of the earliest known galaxies, they flagged one small dwarf galaxy, ...

New 3D map of the early universe from HETDEX reveals faint hydrogen light linking galaxies 9 to 11 billion years ago.

Galaxy Y1 shines thanks to dust grains heated by newly-formed stars (circled in this image from the James Webb telescope). Astronomers have uncovered a previously unknown, extreme kind of star factory ...

Astronomers have unveiled one of the most ambitious maps yet of the early universe, revealing a vast "sea of light" between galaxies that had remained otherwise hidden in previous surveys.

Long before modern telescopes, early astronomers mapped the heavens with math, myth, and sheer curiosity. This crossword quiz celebrates the minds who first charted the cosmos. When you purchase ...

For all the impressive maps astronomers have made of the distant universe, much of the action has stayed out of sight. The brightest galaxies were relatively easy to chart. The faint hydrogen glow ...
