APOD: 2023 February 19 Б Seven Dusty Sisters in Infrared
Explanation:
Is this really the famous Pleiades star cluster?
Known for its
iconic blue stars, the
Pleiades is shown here in
infrared light
where the surrounding dust outshines the stars.
Here three infrared colors have been mapped into visual colors (R=24, G=12, B=4.6
microns).
The base images were taken by NASA's orbiting
Wide Field Infrared Survey Explorer (WISE) spacecraft.
Cataloged as
M45 and nicknamed the
Seven Sisters,
the Pleiades
star cluster is by chance situated in a
passing dust cloud.
The light and
winds
from the massive Pleiades stars
preferentially repel smaller
dust particles,
causing the dust to become stratified into
filaments, as seen.
The featured image spans about 20
light years at the distance of
the Pleiades,
which lies about 450 light years distant
toward the constellation of the Bull
(Taurus).
