Most viewed videos from 2018!



We monitored the solar system and it pays off. Cameras used on Earth and in space shot crazy, startling videos, from meteorites that exploded in the atmosphere, to a Tesla car heading for Mars, to alien weather events on gas giant planets.

Read below to see our most watched videos of 2018! And if that's not enough room looks, do not miss 100 of the best 2018 space photos here.

This year, a special lunar eclipse took place a Blue Moon – the second full moon in a month. Coupled with a close approach between Earth and Moon, this meant that the lunar eclipse of January 31

was a spectacular sight for millions of observers in North America. While many viewers in the US were dehydrated, you can see in the video here that many people could still see the amazing sky view. The next total lunar eclipse in North America will take place on January 21, 2019.

No word can describe the greatness of SpaceX's first launch of Falcon Heavy rockets, which took place on February 6 in the Tesla Roadster (complete with a dummy nicknamed "Starman") thrown down near-Earth orbit. In no time, the traveling astronauts meeting was on its way to Mars orbit – a sequence of breathtaking shots, which you can see in a short video.

The launch of Falcon Heavy hit most important targets, with the two booster rockets safely touching for future product launches; The main core phase did not hold the landing unfortunately.

An American astronaut and a Russian cosmonaut took a surprising roller coaster ride into space on October 11 as a sensor deformed. The Soyuz rocket failed on its way to space, like You can see in this startup video. Within minutes, a routine flight turned into a crash – but the Soyuz probe (the missile has the same name as the rocket) was flawless, bringing the two Expedition 57 crew members back to Earth by parachute.

A few weeks later, Russian space officials released a rocket-boosting view that shows what happened during the flight. The engineers dealt with the problem, and the Expedition 58 started on December 3 from Kazakhstan without errors.

The Chinese Tiangong-1 space laboratory burned on April 1 in the atmosphere over the Pacific Ocean. Interest of satellite observers around the world. Today's high-tech radar systems can track incoming space objects with great precision, so planners can better predict where the re-entering space station would fall. However, forecasting is a challenge because where an object falls depends on the nature of the Earth's atmosphere, how the object staggers, and what the object consists of.

Multiple star-shattering cables let you see stars of different types in this cool NASA video. The data, based on NASA's Kepler Space Telescope (which was out of fuel at the end of this year), also showed a new kind of stellar explosion, different from any other supernova model. The venerable telescope discovered the energy wave of a star shattering into a nearby dust and gas envelope, turning most of the kinetic energy into a brilliant flash of light.

While Jupiter's radiation environment would accomplish this The specially shielded Juno spacecraft was a tough target for astronauts and offered a fantastic view that allowed us to "fly" over the poles of the giant planet. Underneath, huge polar cyclones twirling 2,500 miles (4,000 to 4,600 kilometers) – nearly twice as long as the United States. To cool the view, we hardly knew what was going on at the Jupiter poles before Juno. This makes Juno a valuable asset to better predict the weather behavior of the gas giant.

It was a spectacular year for sky shows with many asteroid flies and exploding meteors in the camera viewfinder. (A meteor is an object that penetrates into the Earth's atmosphere while an asteroid is a space rock.) In April, a newly discovered space rock slipped between the Earth and the Moon; While the flyby was harmless, astronomers reminded us that it was similar in size to the object that exploded over 100 years ago in Tunguska, Russia, flattening the forest.

Also in 2018, two fireballs from various meteors exploded over Michigan and Australia; While they were small and did no harm, the events aroused a strong interest in astronomy and potential meteorites in these areas.

A pretty video that came back from Mars in February showed the moons Phobos and Deimos dance in the dark, but the real story is a wiser illusion. NASA's Mars Odyssey probe captured multiple images over a 17-second period, and the visible motion is due to changes in the focus of the Odyssey Thermal Imaging System (THEMIS) camera. While we were overwhelmed by the images, THEMIS took pictures in the thermal infrared wavelength – a conventional band of light, with which the composition of an object can be better learned.

There are no more space probes at Saturn since Cassini died in 2017, but the Hubble Space Telescope made amazing observations of its place in Earth orbit. The venerable Observatory captured ultraviolet Auroras orbiting the North Pole during and after the summer solstice in the region. The ultimate goal is to better understand how these Auroras change over time. The Earth also gets Auroras when the sun's particles interact with oxygen and nitrogen high up in our atmosphere, but at Saturn, the gas molecules are mostly hydrogen.

In scenes where this happens, you feel like a futuristic video game, the Japanese spacecraft Hayabusa2 deployed Rover on asteroid Ryugu in September. The small world's weak gravity allowed them to move easily and move easily, providing a valuable close-up view of the pebbles and the composition of the asteroid. In 2019, Hayabusa2 should begin its own touchdowns to pick up valuable asteroid dust; Next, there will be a daring return to Earth, where scientists will analyze their precious burden.
