NASA’s SnowEx ground and airborne campaign is a multiyear effort using a variety of techniques to study snow characteristics, and the team began their new field study year in January 2021. Not only is SnowEx learning...

In this live-action program viewers will learn that scientific disciplines, such as Earth Science, Biology, Chemistry, and Physics, are based on observation and experiment. Students will come to understand that the first line of defense...

Nearly every aspect of our lives is fundamentally tied to the land on which we live. Citizens using GLOBE Observer can observe land cover in much greater detail and more frequently than scientists can using satellite...

Launched in October 2006, STEREO traces the flow of energy and matter from the sun to Earth. It also provides unique and revolutionary views of the sun-Earth system. STEREO, when paired with SDO, can now give us the first complete view...

To investigate humans’ impact on freshwater resources, scientists have now conducted the first global accounting of fluctuating water levels in Earth’s lakes and reservoirs – including ones previously too small to measure from space....

Continuing key observations of the Earth is really important to see how our atmosphere, land and oceans are changing over time. A long-term record, combined with cutting edge observations from the new NASA Earth System...

NASA's Hubble Space Telescope took direct ultraviolet images of the icy moon Europa transiting across the disk of Jupiter.



Out of ten observations, Hubble saw what may be water vapor plumes on three of the...

Eclipses set the stage for historic science. NASA is taking advantage of the Aug. 21, 2017 eclipse by funding 11 ground-based scientific studies. As our scientists prepare their experiments for next week, we're looking back to an...

On Jan. 9, 2020, the Lucy Mission officially announced that it would be visiting not seven, but eight asteroids. As it turns out, Eurybates, one of the asteroids along Lucy’s path, has a small satellite....

In this live-action program viewers will learn how to prepare a microscope slide properly. Students will come to understand that when making scientific observations, your methods and observations must be clear to other scientists, so it...

The varied landscapes of the United States have unique relationships with water. On the East Coast, rain is a regular occurrence. In the West, drought is a constant threat. Rivers and lakes fed by rainfall, snowmelt or a mix...

The video discusses the Doppler effect, which is the apparent change in the wavelength of a wave when the source of the wave moves relative to the observer. The narrator explains how the Doppler effect can be observed in everyday life...

This informative and understandable program uses practical examples to help students understand and use the components of the scientific method. Concepts and terminology: hypothesis, experiment, measuring, data, analysis, and conclusion.

William Sheldon's Personality Theory or Body Type Theory

Sheldon's Personality or Body type theory tries to link people's personalities with their body types. It is interesting to look at Sheldon's perspective on body types...

On March 1, the Earth-observing Landsat 5 satellite celebrated 25 years in orbit. Twenty-two years beyond its primary mission lifetime, Landsat 5 is still going strong, making it a keystone of the 37-year Landsat Program. Among Landsat...

This video discusses Charles Darwin's theory of evolution and how it was received at the time it was published. It starts with Darwin's observations during his world expedition in the 19th century, particularly on the finches of the...

In July 1994, the Hubble Space Telescope was poised to use its newly fixed optics to observe one of the most impressive astronomical events of the century - the 21 fragments of Comet Shoemaker-Levy 9 impacting Jupiter. But these...

People the world over are feeling, or soon will feel, the effects of the strongest El Niño event since 1997-98, currently unfolding in the eastern equatorial Pacific Ocean. New satellite observations are beginning to show scientists...

NASA scientists used tree rings to understand past droughts and climate models incorporating soil moisture data to estimate future drought risk in the 21st century.<b<b<br/>r/>r/>

High in the sky, 60 to 65 miles above Earth's surface, winds rush through a little understood region of Earth's atmosphere at speeds of 200 to 300 miles per hour. Lower than a typical satellite's orbit, higher than where most...
