Help scientists understand how galaxies evolve in the Universe at galaxyzoo.org - we've classified millions of galaxies since 2007 and we are still going.

People power in action
Zooniverse is a platform enabling citizen scientists to contribute to research, and it may just form the foundations of a new scientific community

Looking for bars in faraway galaxies
Hi all! My name is Tobias Géron, I'm a postdoctoral researcher at the University of Toronto. I've been using Galaxy Zoo for a few years now to study bars in galaxies. Bars seem to be very common structures in the present-day Universe, with roughly half of all…

Hi all! My name is Tobias Géron, I'm a postdoctoral researcher at the University of Toronto. I've been using Galaxy Zoo for a few years now to study bars in galaxies. Bars seem to be very common structures in the present-day Universe, with roughly half of all disc galaxies having a bar. Bars are also thought to influence their host galaxies in all kinds of fun ways (e.g.

We are thrilled to announce the launch of the Galaxy Zoo JWST project, with ~300,000 galaxy images from the COSMOS-Web survey taken with NASA's James Webb Space Telescope (JWST)! We now need your help identifying the shapes of these galaxies by classifying them on Galaxy Zoo. These classifications will help scientists answer questions about how the shapes of galaxies have changed over time, and what caused these changes and why.

Alyssa’s work can currently be seen in Galaxy Zoo, as we classify cutouts of the stunning images she made of the CEERS JWST Survey’s NIRCam pointings. We often make our own images for the project, but hers were so beautifully made that we knew we should use them instead! 🔭
Alyssa Pagan does a lot more than admire stars from afar—she brings distant worlds to life as a science visuals developer with STScI. Pagan transforms dark, monochromatic images into the dazzling displays of light and color seen on computers, phones and TV screens. 🔭 🧪

She takes black and white data from the Hubble and James Webb space telescopes and uses filters to translate those images into color for the visible spectrum. 🧪

We love a smooth galaxy whose light started travelling to us when our sun wasn't even a glint in the Milky Way's eye!
A smooth galaxy, observed with the Hubble Space Telescope in the COSMOS survey.
It is at redshift 0.67 (lookback time 6.33 billion years) with coordinates (149.67716, 2.27221).
This classification was made in the GZ: Hubble project.
