Principal Investigator Steven Wofsy of Harvard University and atmospheric scientist Paul Newman of NASA’s Goddard Space Flight Center sent back a video postcard of the first two legs of the Atmospheric Tomography, or ATom mission. The...

Launched on Oct. 19, 2008, the Interstellar Boundary Explorer, or IBEX, spacecraft, is unique to NASA's heliophysics fleet: it images the outer boundary of the heliosphere, a boundary at the furthest edges of the solar system,...

Summer 2019, NASA's Space Environment Testbeds, or SET, will launch on its mission to study how to better protect satellites in space. SET studies the very nature of space itself -- which isn't completely...

This video is about the difference between the prepositions "to" and "for". They can be easily confused by students. This video will show you all their differences using examples. It features two amazing diagrams for you to copy and...

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...

NASA's Fermi Gamma-ray Space Telescope has detected beams of antimatter launched by thunderstorms. Acting like enormous particle accelerators, the storms can emit gamma-ray flashes, called TGFs, and high-energy electrons and...

NASA's MODIS satellite instrument reveals how air pollution may alter clouds, affecting global temperatures. This narrated visualization illustrates the effect by showing how ship exhaust leaves brights cloud trails in clean ocean air....

Observatories including NASA’s Hubble Space Telescope found that the interstellar object named ‘Oumuamua gained an extra boost of speed, which likely comes from comet-like jets of gas.Credit: NASA’s Goddard Space Flight...

This nugget introduced the system of particles, rigid bodies about the kind of motion of rigid body.

Appearance and histological features of the trachea under the microscope.

👉 Learn how to solve particle motion problems. Particle motion problems are usually modeled using functions. Now, when the function modeling the position of the particle is given with respect to the time, we find the speed function of...

You sent us your nano questions, and we answered! In this Ask a Scientist – Nano Edition, we join nano expert Karen Wooley, from Texas A&M University.

Every object, planet or person traveling through space has to contend with the Sun's damaging radiation -- and the Moon has the scars to prove it.



Research using data from NASA's ARTEMIS mission — short for...

NASA's Parker Solar Probe mission has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature. Among the findings are new...

Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion, and the major types of mass movements caused by gravity are discussed in this video. Other terminology includes:...

Everything we see and touch is made up of millions of tiny particles. This program is full of colorful examples showing the ways that matter is composed of particles. Vivid animations illustrate how matter consists of different types of...

Air quality in Beijing has risen above hazardous levels in the last few days, reaching 755 on an index that measures particulate matter in the air with a diameter of 2.5 micrometers (PM2.5). A measurement above 100 is considered...

Tiny particles suspended in the air, known as aerosols, can darken snow and ice causing it to absorb more of the sun’s energy. But until recently, scientists rarely considered the effect of all three major types of...

For the first time, a NASA satellite has quantified in three dimensions how much dust makes the trans-Atlantic journey from the Sahara Desert to the Amazon rainforest. Among this dust is phosphorus, an essential nutrient that acts...
