Astronomers Find Color-Shifting Asteroid

The asteroid (6478) Gault is seen with the NASA/ESA Hubble Space Telescope, showing two narrow, comet-like tails of debris that tell us that the asteroid is slowly undergoing self-destruction. The bright streaks surrounding the asteroid are background stars. Image credit: NASA / ESA / K. Meech & J. Kleyna, University of Hawaii / O. Hainaut, European Southern Observatory.

Astronomers using the NASA Infrared Telescope Facility have caught an active asteroid called (6478) Gault in the act of changing color — in the near-infrared spectrum — from red to blue. The asteroid (6478) Gault is seen with the NASA/ESA Hubble Space Telescope, showing two narrow, comet-like tails of debris that tell us that the asteroid is slowly undergoing self-destruction. The bright streaks surrounding the asteroid are background...

Gaia’s all-sky view of our Milky Way Galaxy and neighboring galaxies, based on measurements of nearly 1.7 billion stars. Brighter regions indicate denser concentrations of especially bright stars, while darker regions correspond to patches of the sky where fewer bright stars are observed. The color representation is obtained by combining the total amount of light with the amount of blue and red light recorded by Gaia in each patch of the sky. The bright horizontal structure that dominates the image is the Galactic plane, the flattened disc that hosts most of the stars in our home Galaxy. In the middle of the image, the Galactic center appears vivid and teeming with stars. Darker regions across the Galactic plane correspond to foreground clouds of interstellar gas and dust, which absorb the light of stars located further away, behind the clouds. Many of these conceal stellar nurseries where new generations of stars are being born. Sprinkled across the image are also many globular and open clusters -- groupings of stars held together by their mutual gravity, as well as entire galaxies beyond our own. The two bright objects in the lower right of the image are the Large and Small Magellanic Clouds, two dwarf galaxies orbiting the Milky Way. In small areas of the image where no color information was available -- to the lower left of the Galactic center, to the upper left of the Small Magellanic Cloud, and in the top portion of the map -- an equivalent grayscale value was assigned.

This Hubble image shows the dwarf galaxy UGC 685, which lies in the constellation of Pisces, 15.7 million light-years away. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Planetary Camera 2 (WFPC2) and Advanced Camera for Surveys (ACS). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
