Zooniverse.org has active research projects you can volunteer for, all online. Many years ago I took part in a project and was reviewing pictures of Space and tagging objects. Not super exciting but I gained experience and got to see some cool pictures of Space no one else will probably ever see.

What is the Zooniverse?
The Zooniverse is the world’s largest and most popular platform for people-powered research. This research is made possible by volunteers — more than a million people around the world who come together to assist professional researchers. Our goal is to enable research that would not be possible, or practical, otherwise. Zooniverse research results in new discoveries, datasets useful to the wider research community, and many publications.
