👉 Learn about the points on the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle...

In 2017, NASA's Fermi Gamma-ray Space Telescope played a pivotal role in two important breakthroughs occurring just five weeks apart. But what might seem like extraordinary good luck is really the product of research,...

👉 Learn how to label points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A point is...

In this video, you will learn how rainbows are formed through the behavior of light waves. Sunlight, composed of different wavelengths, enters raindrops, causing the light to split into a multitude of colors. As the light refracts and...

Learn all about angles. An angle is a figure formed by two rays sharing a common endpoint. An angle can be classified as acute, right, obtuse, straight or refrex. An acute angle is an angle which measures less than 90 degrees. A right...

👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

University students and researchers working on a NASA mission orbiting a near-Earth asteroid have made an unexpected detection of a phenomenon 30,000 light-years away. Last fall, the student-built...

👉 Learn how to find the value of an unknown variable in the expressions representing the values of angles given the relationship between the angles. When given expressions representing the values of angles and the relationship between...

This video explores five fun facts about solar power.

For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA’s Neil Gehrels...

NASA's GLAST mission is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France,...

In this video lesson, you will discover how to identify adjacent and vertical angles. We will also learn about the relationship between adjacent angles and how to find a missing adjacent angle. We will discuss the relationship...

👉 Learn how to label points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A point is...

What does the shape between the door and its edge remind you of?

A study conducted by the British Association of Dermatologists shows that using a moisturizer with sun protection factor isn't as effective as applying sunscreen.

👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

Learn all about angles. An angle is a figure formed by two rays sharing a common endpoint. An angle can be classified as acute, right, obtuse, straight or refrex. An acute angle is an angle which measures less than 90 degrees. A right...

Chemists at the University of Iowa, led by associate professor Tori Forbes, are using National Science Foundation funding to investigate how to remove radioactive substances from water. Forbes' team creates and tests various chemical...

Every 3.4 years, pulsar B1259--63 dives twice through the gas disk surrounding the massive blue star it orbits. With each pass, it produces gamma rays. During the most recent event, NASA's Fermi observed that the pulsar's gamma-ray...

👉 Learn about the angles on the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle...

I'm sure you've heard this when you're sitting in the dentist's chair: "Would you like bitewing X-rays?" They likely recommend them every year. They're painless, they don't take much time, and, they won't cost you penny if you're covered...

Understand that angles can be measured by degrees and that a one-degree angle is 1 part out of 360 of a circle.

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...

This colorful, lively series of videos explores the fascinating features of fishes. The major characteristics of this widely diverse group of vertebrates are described through the use of live-action video. Special attention is paid to...
