The Firefly Sparkle Galaxy is the first Milky Way-sized galaxy to ever be found while still in the process of forming.

Researchers identified 378 satellite galaxies around their host systems, an accomplishment requiring meticulous analytical techniques to differentiate these objects from a dense background noise. The ...

The James Webb Space Telescope has captured an image of a baby, Milky Way-like galaxy that formed more than 13 billion years ago. This "Firefly Sparkle" galaxy could reveal how our own galaxy evolved.

Galaxies in the early universe tend to be clumpy, but the new JWST discovery of a "grand design" spiral galaxy just 1.5 ...

The center of our Milky Way galaxy is hidden from the prying eyes of optical telescopes by clouds of obscuring dust and gas.

But the state-of-the-art space observatory has recently imaged two grand design spiral galaxies, and one appears to be the ...

“These galaxies form quickly — gas is sucked inwards to feed black holes and triggers bursts of stars, which are created at rates ten to 100 times faster than our Milky Way.” The next task ...

Astronomers have discovered a pair of young stars near the supermassive black hole at the heart of our galaxy. Studying them ...

Scientists have spotted what appear to be two stars whipping around each other near the supermassive black hole at the center ...

Held together by their mutual gravity, several of the dwarf galaxies (designated D1 to D5) are rhythmically dancing with one another while others are engaged in a "cosmic tug of war," ripping gas and ...

At this stage, the galaxy was about 10,000 times less massive than our ... "The Milky Way continued to grow and evolve over billions of years through mergers with other galaxies and continued ...
