China's new experimental radio antenna facility has been built on land that is 3,700 sq km in size and could possible be used for the Chinese military.

Without communications there is no exploration: To reveal the unknown, a spacecraft must be able to share its data. In a sense, today's space communications networks are like the roadways of ancient empires, allowing information to move...

The mythic hunter Orion, son of the sea-god Poseidon, was himself mortal, but his godly lineage enabled impossible heroic feats, earning him a place in the night sky as a constellation. NASA has developed its own Orion, a hunter for...

New radio waves from outer space have been detected by the Canadian Hydrogen Intensity Mapping Experiment radio telescope, also known as CHIME.

How to distinguish radio waves from space compared to man-made ones? What are some maintenance tasks that help the VLA work properly? What kind of upgrades has the VLA had of recent?<br/>
The Very Large Array Telescope, Part 3

Explain the process of transporting an antenna. Why are the antenna moved into different configurations? What discoveries did the scientists find recently? What do you need to know in order to work in this field?

The Very Large...

It seems that some people in the UK have started to believe a conspiracy theory that 5G is causing Coronavirus. So in this video, we'll discuss the conspiracy theory, explain why it's wrong and tell you some of the crazy things people...

Jason Wright, professor of astronomy and astrophysics at Penn State, has been thinking about the different technosignatures we could pick up using the telescopes we already have, and the telescopes that we could develop in the future.

Lightning in the clouds is directly linked to events that produce some of the highest-energy light naturally made on Earth: terrestrial gamma-ray flashes (TGFs). An instrument aboard NASA's Fermi Gamma-ray Space Telescope was recently...

This video covers natural and artificial sources of light, including topics such as bioluminescence, the visible spectrum, and the use of different wavelengths of light for various purposes such as heat therapy and currency detection....

Black widow spiders and their Australian cousins, known as redbacks, are notorious for an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary...

This video provides an introduction to the 80 2.11 wireless standards and how it works with wireless network traffic. This clip is from the chapter "Wireless Networking" of the series "CompTIA Network+ Certification N10-007: The Total...

The Global-scale Observations of the Limb and Disk, or GOLD, instrument launches aboard a commercial communications satellite in January 2018 to inspect the dynamic intermingling of space and Earth’s uppermost atmosphere. Together,...

To prepare for Servicing Mission 4, Hubble components must endure harsh tests at NASA's Goddard Space Flight Center. This feature explores test facilities at Goddard like: launch phase simulator centrifuge, the acoustic test chamber,...

On its 10th anniversary, Third Rock Radio hosts share the history and evolution of the partnership with NASA and bringing space to the airwaves. HWHAP Episode 224.

In this video, the presenter discusses the interaction between electromagnetic waves and charged particles. The video covers examples of radio waves interacting with electrons and how they can create alternating currents in appropriate...

Learn about the features of the ionosphere! This little-explored region exists between space and Earth. It is home to the aurora, the international space station, a variety of satellites, and radio communication waves. We...

This video explains the concepts used in wired network topologies and describes the logical flow of data. This clip is from the chapter "Cabling and Topology" of the series "CompTIA Network+ Certification N10-007: The Total Course".In...

This video is a lecture on the effects of wavelength and speed on electromagnetic waves. The speaker explains what can happen to a wave at the boundary between two media, including reflection and refraction. They also discuss how...

In this video, we learn how remote controls work by sending signals through electromagnetic signals. The remote control emits infrared radiation, which is received by a small infrared light detector on the device being operated. By...

This nugget explains the source, generation, properties and discovery of electromagnetic waves.

This video provides a clear and concise explanation of how cell phones work, highlighting their evolution from simple communication devices to multi-functional computers. Learn the basics of sending and receiving calls, texts, and data...

The video explains the basics of electromagnetic waves, including their definition as transverse waves that transfer energy from a source to an absorber. It discusses the seven general sections of the electromagnetic spectrum, going from...

This video provides a brief overview of Bluetooth technology and its applications. It explains how Bluetooth uses radio waves to send and receive signals in short distances, making it ideal for wireless connections between devices such...
