This segment from Swift: Eyes through Time traces the history military officers and engineers discovering a strange phenomenon in the sky that astronomers now know are gamma-ray bursts.

Hear about how respect for Earth can help us attain a more sustainable lifestyle in the face of climate change in this video segment adapted from United Tribes Technical College.

In this video adapted from NASA, two members of a NASA research team working to produce carbon nanotubes share some background behind this new technology, show examples of how it will be useful, and explain the various tests being performed to ensure readiness for spaceflight.

Learn about the Chandra X-Ray Observatory's telescope system, science instruments, and spacecraft system in this interactive activity adapted from NASA.

This video from NASA describes the detailed computer modeling used to predict that colliding neutron stars can produce gamma-ray bursts similar to those associated with black holes.

Visualize how comets carrying chemicals necessary for life could have made their way to Earth billions of years ago in this video segment adapted from NOVA.

Amino acids, essential ingredients for life, may have been delivered to Earth by comets billions of years ago, as visualized in this video segment adapted from NOVA.

This video from NASA features the Cosmic Origin Spectrograph (COS), which allows scientists to use spectrographic analysis to assess the composition of intergalactic material.

In this video segment adapted from Navajo Technical College, meet a dendroclimatologist who studies the relationship between precipitation and tree growth in the Navajo Nation.

This video, adapted from NASA, presents rare experimental evidence from the Fermi Gamma-ray Space Telescope supporting Einstein's prediction that space-time is smooth.

In this NASA video, scientists describe how the Extreme Ultraviolet Variability Experiment will sample and track the Sun's ultraviolet irradiance, providing a detailed time sequence of extreme ultraviolet output -- data that can provide advance warning for potentially disruptive energy bursts.

Part 1 of the X-ray Spectroscopy Unit from NASA’s Imagine the Universe! lesson plans includes a series of three lessons on the formation of elements in stars. During this three lesson series, students learn about the life cycle of stars and model the formation of elements in stars. The lessons are a demonstration of type so fusion reactions and modeling not just the changes to matter during the processes but also the energy involved in these reactions.

This video from NASA describes the GLAST satellite, which is equipped with a gamma-ray telescope, and shares some background about the kinds of extreme universal phenomena indicated by the presence of gamma rays.

This video segment from Swift: Eyes through Time introduces and explains theories of the origin of gamma-ray bursts.

In this video segment adapted from United Tribes Technical College, meet Native Americans who are concerned about climate change and believe that action today can help future generations once again live in harmony with Earth.

In this video segment adapted from NOVA, explore the theory that small bits of gas and dust combined to form protoplanets billions of years ago, which in turn collided to create the four rocky planets of the inner solar system.

In this video segment adapted from NOVA, a scientist explains the unexpected heat source fueling widespread volcanic activity on Io, a moon of Jupiter that many had previously assumed to be frozen.

In this video segment adapted from NOVA, scientists are startled to discover evidence for the three key ingredients for life on Saturn's moon Enceladus.

This video segment of Swift: Eyes through Time provides concrete examples to explain the concept that distance in space equals distance in time.

This video adapted from NASA explains how a magnetometer determines magnetic fields around planets.
