Some of the most exciting phenomena in space can’t be seen from Earth because our atmosphere soaks up high-energy light. That’s why NASA built Chandra, the most powerful X-ray telescope ever launched, and the observatory has helped...

Have you ever wondered what are X-rays used for in medicine? And how do they work? Are X-rays dangerous? In this video, we will be answering all the lingering questions you may have about this popular medical imaging technique.

Some 3.9 billion years ago in the heart of a distant galaxy, the tidal pull of a monster black hole shredded a star that wandered too close. X-rays produced in this event first reached Earth on March 28, 2011, when they were...

Astronomers using data from the European Space Agency's XMM-Newton satellite have found a long-sought X-ray signal from NGC 4151, a galaxy that contains a supermassive black hole. The discovery promises a new way to unravel what's...

he Nuclear Spectroscopic Telescope Array, or NuStar X-ray telescope will be launched on June 13. A Pegasus plane-based launch vehicle will deliver the Nustar into a low Earth orbit. The NuStar will use mirrors and detectors separated by...

This video explores the fascinating history and diverse applications of X-rays. From their accidental discovery in 1895 to their use in medical imaging, art restoration, archaeology, and even astronomy, X-rays have revolutionized our...

From the section: CNN-Industry Live Project: Find Medical Abnormalities and Save Life. This section includes a CNN-Industry live project on working with X-Ray images.

Astronomers looking farther back in time than ever before are giving us a better idea of what the early universe must have been like, and we've identified another of the mysterious ultraluminous X-ray pulsars.

During a powerful solar blast in March, NASA's Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi's new role as a solar observatory,...

Researchers using NASA's Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. The object sets a new record for the most luminous gamma-ray pulsar known.



The pulsar...

The video explores the fascinating Archaeopteryx fossil found at the Natural History Museum in London. Scientists have long debated whether this creature could fly or not, given its characteristics resembling both dinosaurs and modern...

Scientists have mapped the environment surrounding a black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space...

In this video Paul Andersen explains how humans use information technology and instrumentation to better understand their surrounds. Technologies (including X-rays, computers, and phones) use electromagnetic waves to improve the lives...

👉 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...

Proteins, and by extension our bodies, depend on the fact that atoms are arranged, spaced, and linked to each other in specific ways. And thanks to June Sutor, we have a better understanding of how those atoms come together and interact...

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral...

Unprecedented observations of a nova outburst in 2018 by a trio of satellites, including NASA’s Fermi and NuSTAR space telescopes, have captured the first direct evidence that most of the explosion’s visible...

Scientists have reached a new frontier in our understanding of pulsars, the dense, whirling remains of exploded stars, thanks to observations from NASA’s Neutron star Interior Composition Explorer (NICER). Data...

Scientists reflect on XMM-Newton’s 20th anniversary. The mission, led by ESA (European Space Agency), has dramatically improved our understanding of the cosmos thanks to detailed X-ray observations. NASA funded two of its three...

In this video, the teacher explains the essential element of ice ages - ice. They discuss how water transforms into ice at its freezing point when enough heat is removed, causing molecules to form a rigid pattern and create a solid...

This video explains the process of bread-making and highlights the importance of the leavening agent in creating a fluffy and crusty loaf of bread. It discusses two methods of raising bread, one using quick leavening agents like baking...

In this video, we explore how batteries work by converting chemical energy into electrical energy. The three main components of a battery, the anode, cathode, and electrolyte, play vital roles in this energy transformation. By...

In this video Paul Andersen describes some of the properties of electromagnetic radiation. The electromagnetic spectrum varies by wavelength from radio waves to gamma rays. We only see a portion of the spectrum known as visible light. ...

The video discusses the production of electromagnetic waves from atoms and nuclei. It covers different examples of producing radio waves, microwaves, x-rays, gamma rays, infrared radiation, visible light, and ultraviolet light. The video...
