While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb's optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb’s mirror alignment, known as “fine phasing,” each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. This image of the star, which is called 2MASS J17554042+6551277, uses a red filter to optimize visual contrast. Credits: NASA/STScI

Hubble Views a Galaxy on the ‘Dark Side’

Resting on the tail of the Great Bear in the constellation of Ursa Major lies NGC 5585, a spiral galaxy that is more than it appears. The

After making landfall near Cameron, Louisiana, as a category 4 storm, Hurricane Laura continued to move northward over western Louisiana. The Visible Infrared Imaging Radiometer Suite (VIIRS) on NOAA-20 acquired this image of Hurricane Laura at 2:50 a.m. Central Daylight Time on August 27, 2020, about two hours after the storm made landfall. Clouds are shown in infrared using brightness temperature data, which is useful for distinguishing cooler cloud structures from the warmer surface below. That data is overlaid on composite imagery of city lights from NASA’s Black Marble dataset. Credits: NASA's Earth Observatory
