The planets generally move west-to-east through the stars (prograde motion), but peridiocally, the motion changes and they move east-to-west through the stars (retrograde motion): The retrograde motion continues for a short time and then the motion switches back to prograde.

The Moon rises fast, so keep a short interval between each frame, 1 or 2 seconds maximum. This will generate enough frames for a time-lapse before the Moon becomes overly bright and begins to blow out. To create a 10-second time-lapse, shoot a minimum of 300 frames for 30 fps or 240 frames for 24 fps is needed.

Outer space refers to the areas between planets, solar systems, galaxies, galaxy clusters and galaxy superclusters. There is little matter in outer space. It is a hard vacuum, without any air. This also makes it extremely cold.

Several different telescopes, both on the ground and in space, have taken images of the disk of the Milky Way by taking a series of pictures in different directions – a bit like taking a panoramic picture with your camera or phone.

Pluto is a dwarf planet that lies in the Kuiper Belt, an area full of icy bodies and other dwarf planets out past Neptune. Pluto is very small, only about half the width of the United States and its biggest moon Charon is about half the size of Pluto.

Saturn is the sixth planet from the Sun and the second-largest planet in our solar system. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium. Saturn is not the only planet to have rings, but none are as spectacular or as complex as Saturn's. Saturn also has dozens of moons.

Up close, stars look like enormous balls of brightly glowing gas, shrouded in wispy trails of glowing smoke.

Space Helmet is a very rare strain created right in beautiful Summit County, Colorado. Smells of fresh fruit and overly pungent pepper.

Drones can either be fully powered by a combustion engine or by a combination of a small combustion engine that produces power to charge an on-board battery pack or act as a generator to an electric motor.

Dancing Astronaut is an American media platform founded in 2009 that primarily covers the electronic dance music industry. The website covers concerts and festivals, reports on entertainment news, reviews music, and publishes original content syndicated across on-demand audio platforms.

Your heart would continue beating and pushing blood out to your organs, but it doesn't contain oxygen. Suffocation and organ failure from lack of oxygen will occur in about 2 minutes with complete brain death in 3 minutes. Your body will freeze solid and float forever in the vastness of space.

An astronaut is standing on a cliff of the mars planet landscape looking at enormous planets, and discover more than 73.

Strong winds are blowing due East with the velocity of 20km/h. The flag will point in direction:Flag Flutter is a flow instability which occurs due to a coupled fluid structure interaction between the flow and the flag.

An astronaut is a person trained, equipped, and deployed by a human spaceflight program to serve as a commander or crew member aboard a spacecraft.

Water globs up and may drown the plant roots or engulf them in air because of the way fluids in space tend to form bubbles. Or if the water floats away from the roots entirely, the plant would not be able to complete photosynthesis, causing them to eventually wilt and die.

The spinning of the earth is called rotation. It takes the earth abut 24 hours, or one day, to make one complete rotation. At the same time, the earth is moving around the sun. This is called a revolution. It takes a little over 365 days, or one year, for the earth to make one full revolution around the sun.

Crouch thought that would be a perfect job. In college, he decided to be a scientist. He hoped that would help him become an astronaut someday.

The Mars Exploration Program is a science-driven program that seeks to understand whether Mars was, is, or can be, a habitable world. To find out, we need to understand how geologic, climatic, and other processes have worked to shape Mars and its environment over time, as well as how they interact today.

When an astronaut goes outside a spacecraft, this space walk is described as extra-vehicular activity (EVA). During a space walk, astronauts wear space suits that protect them from the dangers of being in space and supply them with oxygen to breathe. The astronauts don't walk, but hover, float, and pull to move around.

​Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past.

An Astronaut, Person trained to pilot a spacecraft, operate any of its systems, or conduct research aboard it during spaceflights. The term commonly refers to those participating in U.S. space missions; cosmonaut is the Russian equivalent, and taikonaut is the Chinese equivalent.
