Check out SciStarter’s top projects of 2023!

In 2023, volunteers like you made over two million contributions to SciStarter Affiliate projects. That’s two million data points scientists wouldn’t have had otherwise.

The top five projects this year included both perennial favorites and newcomers, and touched on subjects near and far: the night sky, backyards and even inside our bodies. Check them out below, and if you haven’t yet, give them a try!

As the year comes to a close, we’re also celebrating citizen scientists who have gone above and beyond this year. We encourage you to read the story of SciStarter Ambassador Jim Webster and how and why he’s bringing citizen science to his community on the SciStarter blog. Read it here.

We’ll see you next year!

Play a game on the free mobile app that directly accelerates research on Alzheimer’s disease.

Scientists have discovered links between stalls — clogged blood vessels in the brain — and Alzheimer’s. Reducing these stalls seems to reduce symptoms. Research is ongoing, but a bottleneck is sifting through footage from the brains of mice, scoring blood vessels as “flowing” or “stalled.”

Luckily, we can help. After a quick tutorial you can start scoring stalls and fighting Alzheimer’s.

There are celestial bodies larger than Jupiter lurking near to our Solar System that have remained hidden because they’re so hard to spot.

These cool brown dwarfs can be spotted in telescope images of the night sky, and astronomers need your help to do it. Look through images of space and point out potential brown dwarfs near Earth.
