Here are some of the best videos about Mars Curiosity rover, the surface of the Sun and solar flares, 2012 transit of Venus, galaxy collisions, etc. This is page 2 of the space videos collection. Use the navigation pager near the bottom of each page to view all other pages.
The landing of Curiosity Rover on Mars was an engineering feat. Mars is located so far from the Earth that it takes about 14 minutes for radio waves to travel the distance! This means that remote control of Curiosity Rover is not possible in real-time. In this video, team members of NASA's Jet Propulsion Laboratory share the challenges of the final few minutes of landing the rover on the surface of Mars.
The journey from the top of the atmosphere of Mars to its surface took the rover about 7 minutes. Engineers called it, "The seven minutes of terror." Since remote control in real-time from Earth was not possible, the rover was on its own. Sophisticated computer software controlled the risky phases of its entry, descent, and landing. If any single thing didn't work just right, it was game over.
Why do we find round pebbles in river beds? When small rocks are transported by fast moving water, they become pounded or battered against each other. This makes their sharp or pointed edges rounder and rounder, and over time the small rocks become round in shape.
In September 2012, Curiosity Rover spotted rounded pebbles on the surface of Mars. The finding indicates an ancient stream bed. In the past, water might have flowed on the surface of Mars. In this video, a Curiosity science team member explains the finding: -
The following space video shows a long filament of solar material hovering in the Sun's corona. This filament was ejected out into space on August 31, 2012, with a speed exceeding 1447 kilometers per second (900 miles per second). The coronal mass ejection (CME) did not travel directly toward Earth, but some charged particles from it did interact with the Earth's magnetic fields to create beautiful displays of auroras.
The different viewpoints shown in this video were captured by NASA's Solar Dynamics Observatory (SDO), NASA's Solar Terrestrial Relations Observatory (STEREO), and the joint ESA/NASA Solar Heliospheric Observatory (SOHO): -
The Solar Dynamics Observatory (SDO) is NASA's space based observatory for observing the Sun. Since February 2010, it has been providing amazing space videos and images of the sun. Here is a stunning space video released on Feb 11, 2013 (SDO's third birthday). It shows stunning views of the Sun's surface: -
Does it rain on the Sun? Of course not! However, there is a solar phenomenon known as 'coronal rain'. It occurs when hot plasma in the corona of the Sun cools and condenses along strong magnetic fields, and then slowly falls back on the Sun. This space video shot on July 19, 2012 by NASA's Solar Dynamics Observatory shows what coronal rain looks like: -
In astronomy, a 'transit' occurs when an observer and two celestial bodies are aligned in a straight line in such a manner that the nearer and smaller celestial body appears to move across the face of the farther and larger celestial body, hiding only a small part of it as it moves. This space video shows a rare transit of Venus across the face of the Sun. This rare event occurred on June 5 2012, and attracted significant attention of the mass media, mostly because the next transit of Venus will not occur until 2117 A.D. These pictures and videos of the transit were made from Solar Dynamics Observatory's observations of a number of different wavelengths of the ultraviolet and visible light spectra.
The Andromeda Galaxy is moving toward us with a speed of about 112 kilometers per second (69 miles per second). Scientists predict that it will collide with our Milky Way galaxy in about 4 billion years from now. The two galaxies will ultimately merge to form a single elliptical galaxy. This video explains what exactly will happen to the two galaxies and to our Solar System: -
NGC 922 is a spiral galaxy surrounded by a ring of nebulae. It is located about 150 million light-years away from the Earth in the direction of the Fornax (furnace) constellation. Ripples of star-formation are propagating out across the galaxy, like ripples propagate out from a rock thrown into a pond. About 330 million years ago, a smaller galaxy might have collided with the center of the NGC 922 galaxy to form its distorted structure, as explained in this video: -
This video is a slide-show of some of the most beautiful pictures of the Universe. The background music is Mozart's "Eine Kleine Nachtmusik, Movement No. 1", performed by the Advent Chamber Orchestra.
This video shows cool views of Saturn, its rings, and its moons. These views were captured by NASA's Cassini spacecraft. The background music is Track No. 2 from Nine Inch Nails' album titled "Ghosts I-IV."
