Dark Matter

A galaxy appears to be missing the invisible substance thought to hold such objects together, further challenging long-held assumptions about how galaxies form

A blip of light in the outer reaches of the Milky Way might be a bizarre black hole born at the beginning of time itself—and the long-sought solution to the mystery of dark matter. Astronomers are calling it “Phoebe”

There are parts of the universe, and of the electromagnetic spectrum, that we’re not covering with our telescopes—but not as many as you might think!

Seen just 800 million years after the big bang, an object called LAP1-B is a galactic building block that seems to hold some of the first stars to ever shine

Models giving dark matter more complex behavior could help solve multiple cosmic mysteries

Experts found that the White House budget request for the upcoming fiscal year could defund 54 NASA science missions, including a spacecraft currently studying Jupiter and two planned Venus missions

Long ago, the cosmos might have been a black hole factory—and these primordial objects are even weirder than you think

Astronomers puzzled out minuscule distortions in images of faraway galaxies taken by JWST in order to chart the invisible

Scientists have found the best evidence yet for long-predicted “failed galaxies”

A galaxy cluster discovered on New Year’s Eve in 2020 shines in a new image from NASA’s Chandra X-Ray Observatory

Observations show the disk of our galaxy is not flat but warped and waving. Astronomers are still working out the reasons why

Theorists have found that a “warm” version of cosmic inflation is consistent with known physics, linking it to the hunt for dark matter
