NASA Connects Little Red Dots with Chandra, Webb

A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. A “X-ray dot” found by NASA’s Chandra X-ray Observatory could explain what the hundreds or potentially thousands of these objects are. A paper describing the […]

There’s No Place Like NASA’s New X-59 Hangar Home 

There’s no sign reading “home sweet home” in the hangar where the X‑59 now sits, but the sentiment is unmistakable among those tending to the quiet supersonic aircraft. Located at NASA’s Armstrong Flight Research Center in Edwards, California, the X-59 hangar was built in 1968 but looks like new thanks to a full renovation and […]

Nighttime Imaging Grows Landsat’s Science Value

By Earth Resources Observation and Science (EROS) Center  For more than 50 years, Landsat has imaged Earth’s land and near-shore surfaces as the satellites descend in midmorning orbit, when daily sunlight is optimal. That’s just what they’ve always done.  Currently, Landsat 8 and Landsat 9 circle the globe while also making better use of their ascending paths, […]
