Astronomy Picture Of the Day (APOD)
Stephan s Quintet
17.12.2021
The first identified compact galaxy group, Stephan's Quintet is featured in this eye-catching image constructed with data drawn from the extensive Hubble Legacy Archive. About 300 million light-years away, only four of these five galaxies are actually locked in a cosmic dance of repeated close encounters.
Gemind of the North
16.12.2021
An arid expanse of the Tengger Desert in north-central China, planet Earth fills the foreground of this starry scene. A widefield panoramic view, it was recorded shortly after moonset in the local predawn hours of December 14. Pictured in the still dark sky, stars of the northern winter hexagon surround a luminous Milky Way.
Geminds of the South
15.12.2021
Fireflies flash along a moonlit countryside in this scene taken on the night of December 13/14 from southern Uruguay, planet Earth. On that night meteors fell in the partly cloudy skies above during the annual Geminid meteor shower.
Comet Leonard from Space
14.12.2021
What does Comet Leonard look like from space? Today's featured image from Origin.Space's Yangwang-1 space telescope shows not only the currently bright comet -- but several other space delights as well. Taken...
HH 666: Carina Dust Pillar with Jet
13.12.2021
To some, it may look like a beehive. In reality, the featured image from the Hubble Space Telescope captures a cosmic pillar of dust, over two-light years long, inside of which is Herbig-Haro 666 -- a young star emitting powerful jets.
Meteors and Auroras over Iceland
12.12.2021
What's going on behind that mountain? Quite a bit. First of all, the mountain itself, named Kirkjufell, is quite old and located in western Iceland near the town of Grundarfjcrcur. In front...
Comet Leonard Before Star Cluster M3
11.12.2021
Comet Leonard is now visible to the unaided eye -- but just barely. Passing nearest to the Earth today, the comet is best seen this week soon after sunset, toward the west, low on the horizon.
Postcard from the South Pole
10.12.2021
From this vantage point about three quarters of a mile from planet Earth's geographic South Pole, the December 4 eclipse of the Sun was seen as a partial eclipse. At maximum eclipse the New Moon blocked 90 percent of the solar disk.
Eclipse on a Polar Day
9.12.2021
During polar day, in Arctic and Antarctic summer, the Sun stays above the horizon for periods of 24 hours or more. Recorded on December 4, this fisheye timelapse image tracks the Sun in multiple frames as it completes a circle in the summer sky above Union Glacier, Antarctica.
A Total Eclipse of the Sun
8.12.2021
Few were able to stand in the Moon's shadow and watch the December 4 total eclipse of the Sun. Determined by celestial mechanics and not geographical boundaries, the narrow path of totality tracked across planet Earth's relatively inaccessible southernmost continent.
