VISTA, the Visible and Infrared Survey Telescope for Astronomy, was built to observe in a colour of light that the human eye cannot see – infrared. Infrared light can travel through dust clouds, allowing infrared telescopes to pull back the veils on some of the universe’s most interesting objects.

Discusses the history of space exploration, assesses the NASA program, examines the causes and consequences of space exploration, and also asks students questions on the information provided.

Host Emily Calandrelli speaks to experts who are learning everything they can about asteroids and their potential impact on earth. From the dinosaur killer to the Chelyabinsk meteor of 2013 - we learn about the destructive power of asteroids. Emily takes a trip to the Ames Vertical Gun Range for an experiment that predicts impact size on the moon and the Earth. Emily also travels to Seattle Washington to meet a company that has a plan to profit from...

Part two of the series Everything and Nothing deals with science at the very limits of human perception, where the deepest mysteries of the universe lie. Professor Al-Khalili sets out to answer one very simple question: What is nothing? His journey ends with perhaps the most profound insight about reality that humanity has made. Everything came from nothing.

Is it possible that there are more than 10,000 advanced civilizations in the Milky Way galaxy alone? The formula known as the Drake Equation posits just that. In this program astrophysicist and SETI founder Dr. Frank Drake himself explains the science behind his seemingly outrageous claim, and offers theories about why ET hasn't been found yet. In the video's second half, researchers assess the equation's validity using their expertise in biophysics,...

For the limitless imagination of a scientific mind, the ever-expanding universe is an ideal subject of inquiry! This collection of 50 video clips (45 seconds to 2 minutes 30 seconds each) uses high-quality film footage and detailed animations to investigate the structure of the universe, the stars, the Solar System, the planets of the Solar System, Earth and the Moon, astronomical observation, and space exploration. Video clips include: The Structure...

On September 30, 2010, a NASA space telescope called the Wide-field Infrared Survey Explorer, or WISE, completed its sweeping goal: to record observations of the entire sky in infrared light. The WISE science team is now sifting through the telescope's two million images to spot objects that no astronomer has ever seen before. WISE's most intriguing finds will include mysterious objects called brown dwarfs, blacker-than-coal asteroids, and the Universe's...
