Electromagnetic spectrum color bands
Dec 15, 2017
Are microwaves really just a form of light? What exactly is the electromagnetic spectrum? While our eyes can't see most of this spectrum, except for visible light, we have developed technologies such as giant radio dishes, infrared cameras, x-ray scanners, and utraviolet satellites to peak into the...

Some 1,500 light years from Earth, a mystery of stellar proportions is playing out. A singular star out there captured scientists’ and the public’s imagination in September 2015 with its strangely fluctuating brightness.
A scene like this illustration of dust orbiting the star could be an answer.

NASA's longest-lived mission to Mars has gained its first look at the Martian moon Phobos, pursuing a deeper understanding by examining it in infrared wavelengths.
Colors in this image of the Martian moon Phobos indicate a range of surface temperatures detected by observing the moon on Sept. 29, 2017, with the Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey orbiter.

NASA’s Hubble Space Telescope is helping identify potential celestial targets for the James Webb Space Telescope through a series of preparatory science observations to be completed before Webb is ready to make observations of its own.
This image of the Westerlund 2 cluster includes both visible- and infrared-light observations from Hubble, and was released in 2015 as part of the Hubble Space Telescope's 25th anniversary. The highlighted area, featuring the cluster of stars, was created from visible-light and near-infrared exposures. The black-and-white zoomed portion shows a new image of the star cluster in only one infrared wavelength.

NASA's Hubble Space Telescope has photographed the farthest active inbound comet ever seen, at a whopping distance of 1.5 billion miles from the Sun (beyond Saturn's orbit). Slightly warmed by the remote Sun, it has already begun to develop an 80,000-mile-wide fuzzy cloud of dust, called a coma,... Read More

Ten years ago, NASA's Dawn spacecraft set sail for the two most massive bodies in the asteroid belt between Mars and Jupiter: giant asteroid Vesta and dwarf planet Ceres. The mission was designed to deliver new knowledge about these small but intricate worlds, which hold clues to the formation of... Read More
This false-color image of Ceres highlights differences in surface materials. The color diversity of the material within Occator Crater (center) and its ejecta reveals the elaborate composition of Ceres' crust.

NASA's New Horizons – the fastest-ever spacecraft at launch – left Earth in 2006 and hurtled through the void at nearly one million miles per day toward a mysterious world on the solar system’s outer edge. Three billion miles (4.8 billion km) and 9 1/2 years later, the spacecraft flew-by its target... Read More

A NASA-produced map of areas likely damaged by the Sept. 19 magnitude 7.1 Raboso earthquake near Mexico City has been provided to Mexican authorities to help responders and groups supporting the response efforts. The quake, which struck 75 miles (120 kilometers) southeast of Mexico City, caused... Read More

Thanks to astronomer Edwin Hubble and others, scientists have known since 1929 that our universe is expanding. Its current rate of expansion is called Hubble’s Constant (H0).  There are two leading ways to measure H0, and for fifteen years, they more or less agreed with one another. Not anymore,... Read More

Small satellites provide a cheap, responsive alternative to larger, more expensive satellites. As demand grows, engineers must adapt these “nanosatellites” to provide greater data returns. NASA, in collaboration with educational partners, targets 2021 for the launch of an innovative CubeSat that... Read More
