Galaxies shine in a rainbow of emissions from gas, dust, and stars. Each of these building blocks emits light at specific wavelengths — fingerprints that reveal their age, motion, and chemical makeup.

In a groundbreaking study published in The Astrophysical Journal, astronomers have discovered high-velocity gas clouds near ...

ALMA observations of incredibly distant spiral galaxy BRI 1335-0417 revealed seismic ripples across the realm, offering new insight into early universe star formation and the origin of our Milky Way.

The Sculptor galaxy is similar in many respects to our Milky Way. It is about the same size and mass, with a similar spiral ...

Unusually fast-moving gas clouds near a nearby galaxy suggest they may have come from outside the galaxy. Scientists have ...

A newly discovered barred spiral galaxy dating back 11.1 billion years is rewriting what scientists know about galactic evolution, revealing complex gas dynamics and early bar formation. The post ...

Our solar system is located in the outer regions of the Milky Way, a disk-shaped galaxy with an approximate diameter of 100,000 light years. From Earth, its appearance can only be observed ...

CAPE CANAVERAL, Fla. — Astronomers have revealed a nearby spiral galaxy in all its brilliant glory, shining in thousands of colors. ... composition and motion, according to the scientists.

One of the first suggestions for a larger bar came in 1996, when we had gotten a bit better at mapping out our spiral arms, and the authors of the paper suggested that the Galaxy would look way ...

If it looks like spiral galaxy IC 2613 is staring at you, it’s not being rude: a collision with its nearest neighbor sent a wave crashing through the galaxy, which produced the strange eye-like ...

This not-too-distant celestial body (it's only 42 million light-years away!) is a spiral galaxy much like Earth's own Milky Way. But because of where we are and how it's situated, Hubble's photo ...
