Explore Space Like an Astronomer



Each subscription to The Online Telescope comes with five accounts: one master account and four sub accounts. Feel free to invite your family and friends.

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.

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.

Comet Leonard really is a lovely surprise, with the intense green glow of its coma, dust tail, and the unique shape of its ion tail. And now, a few days before Christmas, it looks like a huge Christmas Tree adorned with a giant green bauble! - Cameron McEwing, New Zealand, Dec 21st, 2021
