University of Minnesota researchers have developed a new tool to measure ethane from space, leading to a better understanding of fossil fuel emissions worldwide. Ethane is commonly found in natural gas and is primarily used ...

Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas ...

Launched in 2011, NASA's NEOWISE mission operated in Earth's orbit until late last week. It detected more than 3,000 near-Earth objects or NEOs—asteroids or comets whose orbits can bring them close to Earth, even with the ...

Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared (47% share of the spectrum), visible (46%), and ultra-violet (only 6%) light. Bright sunlight provides luminance of approximately 100,000 candela per square meter at the Earth's surface.

While a mosquito bite is often no more than a temporary bother, in many parts of the world it can be scary. One mosquito species, Aedes aegypti, spreads the viruses that cause over 100,000,000 cases of dengue, yellow fever, ...

In a new study, a team of astrophysicists led by CU Boulder has set out to unravel the mysteries of UFOs—not the alien spacecraft, but a class of unusually large and red galaxies that researchers have nicknamed Ultra-red ...

If aliens modified a planet in their solar system to make it warmer, we'd be able to tell. A new UC Riverside study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet.

So much science news this week. It's like a torrential deluge of information bursting explosively through a levee of ignorance. Who built that levee, anyway? How did they get that through the legislature? Anyway, of the hundreds ...

Imagine being able to watch the inner workings of a chemical reaction or a material as it changes and reacts to its environment—that's the sort of thing researchers can do with a high-speed "electron camera" called the ...

Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400-700 nm), but shorter than that of terahertz radiation (100 µm - 1 mm) and microwaves (~30,000 µm). Infrared radiation spans roughly three orders of magnitude (750 nm and 100 µm).
