True secret

"How To get to Mars" is a clip from the IMAX documentary "Roving Mars" from 2006. This is an edited short version. From Wiki : Spirit, MER-A (Mars Exploration Rover -- A), is a robotic rover on Mars, active from 2004 to 2010. It was one of two rovers of NASA's ongoing Mars Exploration Rover Mission. It landed successfully on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, Opportunity (MER-B), landed on the other side of the planet. Its name was chosen through a NASA-sponsored student essay competition. The rover became stuck in late 2009, and its last communication with Earth was sent on March 22, 2010. The rover completed its planned 90-sol mission. Aided by cleaning events that resulted in higher power from its solar panels, Spirit went on to function effectively over twenty times longer than NASA planners expected following mission completion. Spirit also logged 7.73 km (4.8 mi) of driving instead of the planned 600 m...

Humanity has yet to be contacted by any life from beyond our planet. Ignoring  Area 51  truthers and UFO sightings, we have received zero messages from any life—no ETs, no Ewoks, nothing. Given the incredible advances in technology in the past 100 years, there is a good chance that aliens who became spacefaring civilizations even a few hundred years before us would be unimaginably more advanced than we are now. We have thought of many different ways to transmit messages across the cosmos. So if super-advanced aliens wanted to communicate with us, here are some ways they could do it. 10 Plain Old Radio Waves This is what first comes to most people’s minds when they think of communicating with  aliens . Receiving messages in this form is the subject of many books and movies, like  Contact  or  Independence Day , and it is a good start. After all, we’ve been playing around with radio waves for over a century, and we’ve become rather goo...

We all know that   black holes  gobble matter up like nothing else in the universe. But science has revealed an unbelievable arsenal of tricks in the black holes’ playbook. From nearly achieving impossible-sounding speeds to self-harming and even a bit of banditry, these celestial objects are a lot more versatile than we give them credit for. 10 Spin Really, Really Fast For the first time, scientists accurately measured a supermassive black hole’s spin. And it’s a doozy: 84 percent of the  speed of light . NGC 1365’s central black hole, 60 million light-years away, is mind-numbingly fast as well as enormous. It’s 3.2 million kilometers (2 million mi) across and boasts several million  solar  masses. As it spins, it drags space-time along with it, creating a scorching maelstrom of X-ray-spewing gas and dust that spirals down its drain. The matter likely fell from a single direction, giving it the constant unidirectional push required to attain...
