The Hubble Space Telescope was launched in 1990 and is still in service today. Just as Galileo’s first telescope opened the door to a new world beyond what the naked eyes can see, the Hubble Space Telescope broke through heaven’s gates and showed us a world beyond the boundaries of space-time, capturing even images of […] Continue reading

Contrary to popular belief, there is gravity in space, in fact gravity is everywhere. On the International Space Station, there is as much gravitational force as it is on Earth’s surface.
