For Higher Education
"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
“Slooh brings the wonder, excitement, and dreams children associate with space exploration and the cosmos directly into every classroom.”
Dr. David Goldblatt
Former Superintendent of Saddle River School District, NJ
"I don't like online, kids spend too much time in front of screens,
but Slooh is the exception."
