This video explores the fascinating phenomenon of how our perception of light and dark objects can be influenced by the background they are presented on.

The History of Physics and Its Applications

Watch "Return to Venus - Part II" at:From Galileo and the Heliocentric model of the Solar System to James Hansen and climate research, observations of the planet Venus throughout history have given us the perspective we need to...

Jupiter's bright Equatorial Zone swirls with dark patches, dubbed "hot spots" for their infrared glow. These holes in the ammonia clouds at the top of the atmosphere allow a glimpse into Jupiter's darker, hotter layers below. In 1995...

From Galileo and the Heliocentric model of the Solar System to James Hansen and climate research, observations of the planet Venus throughout history have given us the perspective we need to understand our own place in the universe....

The concept of a Star Tracker can be traced back to the early sailors who used to navigate the open seas using star field patterns. Star Trackers act as the eyes of the satellite pointing it in the right direction. This is important...

Humans have always looked up at the sky. They used astronomy to track time, orient their cities, decide when to plant their crops, and even based their religious practices on their celestial world. But there was much more to learn.<br/>

Parked in space a million miles from Earth, the Earth Polychromatic Imaging Camera (EPIC) onboard the Deep Space Climate Observatory (DSCOVR) captures glimmers of reflected sunlight, evidence of ice crystals in the...

A portion of our culture distrusts the scientific method, assuming that there are transcendent truths unknowable by science. But nothing is truly out of bounds for science. If it's real, it can be studied, and tested. Perhaps the...

Humans have always wanted to learn about the Sun, but our understanding of our favorite star has changed through the centuries. In prepartion for Sun360, when the STEREO spacecrafts will provide the first uninterrupted view of the...

On March 20, 2009, at 1:00 p.m. EDT, join a panel of scientists for a live Sun-Earth Day Webcast on www.nasa.gov and NASA TV. During the webcast, scientists will share discoveries about the sun, while students monitor the sun and prepare...

En física es super importante el concepto de sistema de referencia. A la hora de hablar de las Leyes de Newton o de cualquier movimiento rectilineo o circular, este concepto será clave. También está íntimamente relacionado con el de...

Galileo Galilei is known as the “father of modern science.” Fascinated by gravity, motion, and the movement of heavenly bodies, Galileo’s work influences how we understand our own world and the solar system. His contributions include...

From the ancient beliefs of Earth being the center of the solar system to the discovery of other planets orbiting the Sun, we delve into the history and classification of these celestial bodies. A planet is an astronomical or celestial...

People have been looking at outer space through telescopes since the time of Galileo. Learn how telescopes work and how they have expanded what we know about our solar system.

The heliocentric model of Copernicus was extremely controversial in its time, but it wasn't the end of the story. Johannes Kepler used the data of his boss, Tycho Brahe, to further corroborate it, but also show that the planets do not...

The Hubble Space Telescope has captured even more evidence of water vapor plumes on Jupiter's icy moon Europa. The probable plumes appear to be repeating in the same location and correspond with a relatively warm region on...

The video discusses the exploration of outer planets, particularly Jupiter, through the use of powerful telescopes and spacecrafts. It highlights the contributions of early scientists like Galileo and the advancements in technology that...

Europe experienced one of the most remarkable periods in history roughly between 1550 and 1700, when three of history's most important events were occurring simultaneously: the Renaissance, the Reformation, and the Scientific Revolution....

Physics is the grandaddy of the sciences! When those ancient dudes in togas were philosophizing about the way the universe works, they were setting the stage for what we now know of as physics, even though it didn't really get going...

Find out which discoveries caused Galileo to be persecuted.

Did you know that everything is moving? Even you, as you're sitting perfectly still, because the earth is moving, and the sun, and the galaxy, and so forth. For this reason, it only makes sense to talk about the motion of some object...
