What if we fill a crater on the moon with water? Can we create a lake? Would the water stay in this artificial lake?
We can turn Earth into a giant telescope. According to a recent study titled “The ‘Terrascope’: On the Possibility of Using the Earth as an Atmospheric Lens”, published by David Kipping of Columbia University, our planet offers an opportunity for pronounced lensing.
Ian Whittaker, Nottingham Trent University and Gareth Dorrian, University of Birmingham Half a century after humans first walked on the moon, a number of private companies and nations are planning to build permanent bases on the lunar surface. Despite the technological progress since the Apollo era, this will be extremely challenging. So how should you […]
“Tranquility Base here. The eagle has landed.” Neil Armstrong said so as the Apollo Lunar Module Eagle touched down on the lunar surface on Sunday, July 20, 1969, at 20:17 UTC.
Jean Creighton, University of Wisconsin-Milwaukee Much of the technology common in daily life today originates from the drive to put a human being on the Moon. This effort reached its pinnacle when Neil Armstrong stepped off the Eagle landing module onto the lunar surface 50 years ago. As a NASA airborne astronomy ambassador and director […]
Now we’re living on a warm, hospitable planet. As Carl Sagan has said “That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.” We, humans, are the unquestionable rulers of our little oasis in a hostile universe. But […]
This amazing photo of the 2019 Solar Eclipse from the Moon’s orbit was taken on July 2, 2019, by the Chinese lunar satellite DSLWP-B (Longjiang-2).

Hubble Space Telescope was launched on April 24, 1990, and entered service on May 20, 1990. Since then, it has observed all the planets in our Solar System, apart from Earth and Mercury. Earth is far better studied by geologists on the ground and specialized probes in orbit. Hubble can’t observe Mercury as it is […]
Jupiter’s moon Ganymede is the largest and most massive of the Solar System’s moons. It has a mean radius of 2634.1±0.3 km (about 1636 miles, 0.413 Earths). For comparison, our Moon’s radius is 1,737.1 km (1079 mi). What if Ganymede was the Earth’s second moon? How would it look in the sky, if it was […]
