A crucial, and often underappreciated, facet of science lies in deciding how to turn the raw numbers of data into useful, understandable information -- often through graphs and images. Such visualization techniques are needed...

A feature from NASA's Ames Research Center in Silicon Valley originally posted on June 13, 2017.

All objects emit infrared radiation and the characteristics of the infrared radiation are primarily dependent on the temperature of the object. One of the unique features of the new Quantum Well Infrared Photodetector (QWIP)...

Once installed on the Hubble Space Telescope during the upcoming servicing mission this year, COS will dramatically advance physics and astrophysics research on the origin of the Universe, astronomical objects, evolution of galaxies, and...

This video is a lecture on the colors of opaque objects and how light interacts with different surfaces to define the color of an object. It explains how white light is a combination of all visible colors and that surfaces with color...

For the past 30 years the Hubble Space Telescope has continued its important mission of uncovering the mysteries of the universe. One of those mysteries that Hubble has helped us understand...

Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface.



Temperatures in the corona — the...

The video is a lecture on filters and how they work. It discusses how white light is a combination of all visible wavelengths and how filters are materials that are transparent and only permit certain wavelengths of light to transmit...

The universe is microwaving itself. A mystery signal discovered in the 1960s led to a Nobel prize. In this video, Dianna explores one of the most mysterious discoveries in physics - a constant microwave signal that seemed to be coming...

The Hubble Space Telescope has been revealing the secrets of the universe for over 30 years, but it turns out Hubble has some secrets of its own!



The question is: What does Hubble’s...

The Solar Dynamics Observatory, or SDO, spacecraft was launched on Feb. 11, 2010, and began collecting science data a few months later. With two imaging instruments – the Atmospheric Imaging Assembly and the Helioseismic and...

Explore how gemstones get their colors. We learn that gemstones absorb and reflect certain light waves based on their chemical structures, resulting in different colors. Some gemstones are self-colored, while others are colored by...

By studying X-rays in deep space, we can learn about some of the most violent and extreme objects in the universe, such as black holes and the remains of stars that have exploded. NASA’s Imaging X-Ray Polarimetry Explorer, IXPE, will...

Dean Pesnell, the SDO Project Scientist, explains how the the Extreme Ultraviolet Variability Experiment (EVE) instrument will allow us to better measure solar irradiance in extreme ultraviolet wavelengths. This type of irradiance,...

For half a century, the Landsat mission has shown us Earth from space. Now, come along with us on a "roadtrip" through the decades to see how the technology on this NASA and U.S. Geological Survey partnership has...

Landsat satellites circle the globe every 99 minutes, collecting data about the land surfaces passing underneath. After 16 days, the Landsat satellite has passed over every spot on the globe, and recorded data in 11 different...

At the end of June 2013, NASA will launch its newest mission to watch the sun: the Interface Region Imaging Spectrograph, or IRIS. IRIS will show the lowest levels of the sun's atmosphere, the interface region, in more detail than...

A combination of lightning, drought and human activity caused fires to scorch more than one-third of Yellowstone National Park in the summer of 1988. Within a year, burn scars cast a sharp outline on the 793,880 acres affected by...

In its five years in space, Landsat 8 has racked up an impressive line of statistics. The satellite made 26,500 orbits around Earth. It captured 1.1 million "scenes" of our home planet. Its images now represent 16 percent of all...

Lesson 17 (Waves, Light, and Sound) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need a review of AP Physics concepts before the exam? This course is for you! Exercises...

On July 20, 2015, NASA released to the world the first image of the sunlit side of Earth captured by the space agency's EPIC camera on NOAA's DSCOVR satellite. The camera has now recorded a full year of life on Earth from its...

When the moon passes through the Earth's shadow, it causes the moon to look very unusual for a short period of time. This event is called a lunar eclipse, and it occurs roughly twice a year. There's one viewable to folks outside...

On August 1, 2008 a rare total solar eclipse will appear in the skies over parts of Canada, Greenland, Russia, Mongolia, and China. During this spectacular event, the moon will cross in front of the sun, completely blocking out the...

A team of three scientists have two minutes to complete an experiment during the 2017 total solar eclipse.
