Stellar heavy metals can trace history of galaxies

Astronomers have cataloged signs of nine heavy metals in the infrared light from supergiant and giant stars. New observations based on this catalog will help researchers to understand how events like binary neutron star mergers ...

Polluted wastewater in the forecast? Try a solar umbrella

Evaporation ponds, which are commonly used in many industries to manage wastewater, can span acres, occupying a large footprint and often posing risks to birds and other wildlife. Yet they're an economical way to deal with ...

Flying observatory maps the Milky Way

A new panoramic image based on data captured by NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) shows the bustling center of our galaxy like it has never been seen before.

Spitzer studies a stellar playground with a long history

This image from NASA's Spitzer Space Telescope shows the Perseus Molecular Cloud, a massive collection of gas and dust that stretches over 500 light-years across. Home to an abundance of young stars, it has drawn the attention ...

On-chip light source produces versatile range of wavelengths

Researchers have designed a new chip-integrated light source that can transform infrared wavelengths into visible wavelengths, which have been difficult to produce with technology based on silicon chips. This flexible approach ...

Spitzer spots a starry region bursting with bubbles

This infrared image from NASA's Spitzer Space Telescope shows a cloud of gas and dust full of bubbles, which are inflated by wind and radiation from young, massive stars. Each bubble is filled with hundreds to thousands of ...

Spotting merging galaxies

Over 30 years ago, the Infrared Astronomy Satellite discovered that the universe contained many extremely luminous galaxies, some more than a thousand times brighter than our own Milky Way, but which are practically invisible ...
