How can you use an infrared camera to see through walls? To inspect the scene of a crime? To catch a thief in hiding?! This cool device attaches to your smartphone and has an infrared/visible light camera combo that allows you to see the...

This video discusses how electromagnetic waves can interact with charged particles, specifically electrons in atoms. It explains how electromagnetic waves can cause electrons to absorb energy and jump to higher energy levels or emit...

Ozone depletion may have triggered a mass die-off of ancient fish and plants by ultraviolet ray exposure 358 million years ago.

Researchers in India have discovered a species of tardigrade that absorbs UV radiation and emits blue light, according to a paper published in the journal Biology Letters. <br/>

Disinfection robots, thermal body cameras and virus-killing air-con systems — welcome to the Covid-free office of the future. A workplace in Bucharest filled with anti-virus innovations could become the new standard in office design.

Most large galaxies contain a giant central black hole. In an active galaxy, matter falling toward the supermassive black hole powers high-energy emissions so intense that two classes of active galaxies, quasars and blazars, rank as...

Exposure to ultraviolet rays may increase biodiversity of the gut microbiome in humans.

Astronomers at NASA's Goddard Space Flight Center in Greenbelt, Md., and the Pennsylvania State University in University Park, Pa., have used NASA's Swift satellite to create the most detailed surveys of the Large and...

NASA Astrophysicist and Pioneers Program Lead Scientist Michael Garcia discusses the new program’s first mission concepts selected for further development.

NASA's Swift satellite has acquired the highest-resolution view of the neighboring spiral galaxy M31. Also known as the Andromeda Galaxy, M31 is the largest and closest such galaxy to our own. It's more than 220,000 light-years across...

NASA's Swift satellite rode to orbit aboard a Delta II rocket on November 20, 2004, and it's still going strong. Swift's unique instrumentation allows it to quickly locate an interesting high-energy outburst, automatically determine...

This video explains how black lights work and their various applications. Black lights emit long wave ultraviolet light, which is invisible to the human eye but causes certain objects, like phosphors, to glow.

The coronavirus scare has prompted airports to come up with innovative gadgets designed to combat the virus. <br/>

A colder than usual winter in the southern hemisphere fed a deep and larger than average hole that persisted for a longer period than usual.

On Dec. 7, 1968, an Atlas-Centaur rocket carrying NASA’s heaviest and most ambitious uncrewed satellite to date blasted into the sky from Launch Complex 36B at Cape Canaveral Air Force Station, Florida....

Dean Pesnell, the SDO Project Scientist, explains how the the Extreme Ultraviolet Variability Experiment (EVE) instrument will allow us to better measure solar irradiance in extreme ultraviolet wavelengths. This type of irradiance,...

The philosophy of NASA's Mars Program has been "Follow the water," but "Where did the atmosphere go?" is still a lingering question. Although fluvial features such as dry riverbeds are visible on Mars, the atmosphere today is too thin...

For the first time, NASA’s Neil Gehrels Swift Observatory tallied the water lost from an interstellar comet as it approached and rounded the Sun. The object, 2I/Borisov, traveled through the solar system in late...

The Lyman-Alpha Mapping Project (LAMP) is an instrument on NASA's Lunar Reconnaissance Orbiter mission to map and study the Moon. LAMP is a spectrograph that images the ultraviolet region of the spectrum. Utilizing the faint glow of...

Launched on Feb. 11, 2010, the Solar Dynamics Observatory, or SDO, is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun's atmosphere, magnetic field and also...

This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames...
