This short video titled “how orbits work” beautifully explains what is an orbit and what you should do to enter into a stable one around Earth, or any other celestial body.
On January 9, 2012, astronauts aboard the International Space Station (ISS) took this amazing footage of the orbital moonset.
Well, of course, you cannot see a black hole – but the newly discovered one has two stars orbiting it, and you can see these companion stars even with the naked eye from Earth. The triple system is named HR 6819. Named QV Tel Ab, the inner component of the system is the closest black hole to Earth.
The system appears as a variable star that is dimly visible to the naked eye.
The American television personality, musician, puppeteer, writer, and producer “Mister” Fred Rogers (Fred McFeely Rogers, March 20, 1928 – February 27, 2003) reads some of Apollo 15 Astronaut Al Worden’s space poems at his TV show “Mister Rogers’ Neighborhood”, which ran from 1968 to 2001.

This awesome map, using imagery taken by NASA’s Lunar Reconnaissance Orbiter (LRO), enables us to explore Moon within our browsers.
All stars emit varying amounts of light over time – and the Sun is no exception. Such changes in starlight can help us understand how habitable any planets around other stars are – a very active star may bombard its planets with harmful radiation. Now a new study, published in Science, shows that the Sun is significantly less active than other, similar stars.
Robert Frost, a NASA employee, has shut down a conspiracy theorist on the popular question-answer site Quora. He perfectly explained how NASA sends probes and rovers to Mars. I wanted to share it here because his answer is so informative and enlightening.
