Planets in our Universe can get extremely large, but stars get even bigger. In this video we explore the sizes of moons, planets, stars, and even beyond, including black holes and even galaxies. Basically a comparison of the entire Universe.

This is the original landscape-format version of the short movie Cosmic Eye, designed by astrophysicist Danail Obreschkow. The movie zooms through all well-known scales of the universe from minuscule elementary particles out to the gigantic cosmic web. This project was inspired by a progression of increasingly accurate graphical representations of the scales of the universe, including the classical essay "Cosmic View" by Kees Boeke (1957), the short movie "Cosmic Zoom" by Eva Szasz (1968), and the legendary movie "Powers of Ten" by Charles and Ray Eames (1977). Cosmic Eye takes these historical visualisations to the state-of-the-art using real photographs obtained with modern detectors, telescopes, and microscopes. Other views are renderings of modern computer models. Vector-based blending techniques are used to create a seamless zoom. This 2018-version of Cosmic Eye contains improved graphics and minor technical corrections compared to the 2011-version in portrait format. ► Support via PayPal: https://tinyurl.com/scientificus Donations are vital to develop, update and translate Cosmic Eye.

This 11-minute animation depicts key events of NASA's Mars Science Laboratory mission, which will launch in late 2011 and land a rover, Curiosity, on Mars in August 2012.

The moment has finally arrived, it's time for Felix Baumgartner to perform the space dive. Taken from Red Bull Space Dive. This is a channel from BBC Studios who help fund new BBC programmes. Service information and feedback: https://www.bbcstudios.com/contact/co...

The Deep Space Network, NASA’s international collection of giant radio antennas used to communicate with spacecraft at the Moon and beyond, helps scientists and engineers use gravity and radio science experiments to learn more about our planetary neighborhood. After reaching a spacecraft reaches its destination, it uses radio antennas to communicate with the Deep Space Network, which in turn transmits radio signals back to the spacecraft. Every spacecraft travels in a predetermined path emitting radio signals as it orbits around its target. Scientists and engineers can infer the spacecraft's location and how fast it's going by measuring changes in the spacecraft's radio signal frequency. This is made possible by the Doppler effect, the same phenomenon that causes a siren to sound different as it travels towards and away from you. The Doppler phenomenon is observed here when the spacecraft and the Deep Space Network antenna move in relation to each other. Differences between the frequency of radio signals sent by the spacecraft as it orbits and signals received on Earth give us details about the gravitational field of a planetary body. For example, if the gravity is slightly stronger, the spacecraft will accelerate slightly more. If gravity is slightly weaker, the spacecraft will accelerate slightly less. By developing a model of the planetary body's gravitational field, which can be mapped as a gravitational shape, scientists and researchers can deduce information about its internal structure. The Deep Space Network was developed by and is managed by NASA’s Jet Propulsion Laboratory (JPL) in Southern California. The antennas of the Deep Space Network are the indispensable link to robotic explorers venturing beyond Earth. They provide the crucial connection for commanding our spacecraft and receiving never-before-seen images and scientific information on Earth, propelling our understanding of the universe, our solar system and ultimately, our place within it. JPL manages the Deep Space Network for the Space Communications and Navigation (SCaN) Program, based at NASA Headquarters within the Space Operations Mission Directorate.
