"With Slooh's Online Telescope my students are finally able to "do" astronomy in an authentic, hands-on way befitting of a science course.”

Greg Schwanbeck | Westwood High School

“I like the variety of Quests, both in topics and level of difficulty.”

Theresa Rodriguez | San Antonio STEM Magnet

“I don't like online, kids spend too much time in front of screens, but Slooh is the exception."

Slooh in Action

Introduction to Exploring Space with Slooh


You are never too old or too young to start, but the learning materials are designed for 4th grade to higher education, so age nine to adult.


Subscription comes with five accounts: one master account and four sub-accounts. Feel free to invite your family and friends. (Not included with Advanced Amateur Astronomer account)

Slooh's telescopes are much better quality and have automated cameras attached to them which are necessary to see faint objects in space. Slooh's online telescopes are also situated on mountain tops above the clouds and away from light pollution, problems that make exploring space impossible for most people. You'll be learning to control telescopes just like professional astronomers, via a computer interface, which will help you get into college or join the Space Force someday. Plus, you won't be doing it alone--you'll find support from a worldwide community exploring space together.
