NASA Airborne Sensor’s Wildfire Data Helps Firefighters Take Action

NeRD

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s AVIRIS-3 airborne imaging spectrometer was used to map a wildfire near Cas-tleberry, Alabama, on March 19. Within minutes, the image was transmitted to firefighters on the ground, who used it to contain the blaze. NASA/JPL-Caltech, NASA Earth Observatory The map visualizes three wavelengths of infrared light, which are invisible to the human eye. Orange and red areas show cooler-burning areas, while yellow indicates the most intense flames. Burned areas show up as dark red or brown. NASA/JPL-Caltech, NASA…

Astronomers discover dark matter ‘bridge’ linking colliding galaxies: ‘This is the missing piece we’ve been looking for.’

NeRD

Astronomers have discovered a long-missing element of a galactic collision involving the Perseus galaxy cluster, located 240 million light-years from Earth. This element, a newly detected “subcluster,” is 1.4 million light-years to the west of NGC 1275, the central galaxy of the Perseus cluster. These two elements seem to be connected by a faint “bridge” of material. The structural backbone of this bridge is dark matter, the universe’s most mysterious “stuff.” Dark matter remains effectively invisible by not interacting with light, but its interaction with gravity has helped to shape…

Fixing the Hubble Space Telescope: A timeline of NASA’s shuttle servicing missions

NeRD

The Hubble Space Telescope is a masterwork of engineering and human ingenuity. Hubble is comparable in size and weight to a large school bus, but its contributions to science and astronomy could fill libraries. Not only is Hubble one of Earth’s premium sources for absolutely incredible, out-of-this-world imagery, it is also a testament to human curiosity and determination. The telescope has been in operation for over 30 years, undergone a total of five servicing missions and delivered nearly 250 terabytes of data in contributions to our understanding of the universe.…

Planetary Alignment Provides NASA Rare Opportunity to Study Uranus

NeRD

5 Min Read Planetary Alignment Provides NASA Rare Opportunity to Study Uranus Artist's illustration showing a distant star going out of sight as it is eclipsed by Uranus – an event known as a planetary stellar occultation. Credits: NASA/Advanced Concepts Laboratory When a planet’s orbit brings it between Earth and a distant star, it’s more than just a cosmic game of hide and seek. It’s an opportunity for NASA to improve its understanding of that planet’s atmosphere and rings. Planetary scientists call it a stellar occultation and that’s exactly what…
