The battle is on for the title of "America's Scientist Idol." Videotaped at the 2013 annual meeting of the American Association for the Advancement of Science, this "game show" pits six scientists against each other to see who can best...

This video is a lecture that explains the concept of background radiation, which is a type of ionizing radiation that humans are exposed to every day but at low levels. The video discusses the four main types of ionizing radiation, which...

NASA’s Fermi telescope discovered a vast halo around a neutron star that could explain why there is so much antimatter near Earth. <br/>

The video is a lecture on the natures and properties of nuclear radiations. The speaker discusses the three types of ionizing radiation: alpha particles, beta particles, and gamma rays. They explain the ionizing and penetrating abilities...

NASA spacecraft deliver stunning visual imagery of the cosmos, but we can also experience that data by turning it into sound.

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...

On June 11, NASA's Fermi Gamma-ray Space Telescope celebrates a decade of using gamma rays, the highest-energy form of light in the cosmos, to study black holes, neutron stars, and other extreme cosmic objects and...

On April 15, a brief burst of high-energy light swept through the solar system, triggering instruments on many NASA missions. Now, multiple international science teams conclude that the blast came from a...

What we call "light" is actually just a tiny fraction of the broad range of radiation on the electromagnetic radiation spectrum. The entire span stretches from very-low-energy radio waves through microwaves, infrared light,...

An international science team says NASA's Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun, which should block direct light from these events. This...

A long time ago in a galaxy half the universe away, a flood of high-energy gamma rays began its journey to Earth. When they arrived in April, NASA's Fermi Gamma-ray Space Telescope caught the outburst, which helped two...

There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the...

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,...

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,...

The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any previously seen from the object. The outburst was first detected by NASA's Fermi Gamma-ray Space Telescope on April 12...

The History of Physics and Its Applications

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,...

The Fermi Gamma-ray Space Telescope is a NASA observatory designed to reveal the high-energy universe in never-before-seen detail. With Fermi, astronomers have a unique tool to explore high-energy processes associated with...

Our universe is more than a serene landscape of stars--it is teeming with activity from some extremely violent events. In a presentation at the IMAX theatre at the Smithsonian National Air and Space Museum in Washington, D.C. on...

In three years, NASA's Fermi has detected more than 100 gamma-ray pulsars, but something new has appeared. Among a type of pulsar with ages typically numbering a billion years or more, Fermi has found one that appears to have been...

This compilation summarizes the wide range of science from the first five years of NASA's Fermi Gamma-ray Space Telescope. Fermi is a NASA observatory designed to reveal the high-energy universe in never-before-seen detail. Launched in...

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...

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...

Merging data on high-energy bursts seen on Earth by NASA's Fermi Gamma-ray Space Telescope with data from ground-based radar and lightning detectors, scientists have completed the most detailed analysis to date of the types of...
