Astronomy Picture Of the Day (APOD)
Messier 20 and 21
5.08.2020
The beautiful Trifid Nebula, also known as Messier 20, is easy to find with a small telescope in the nebula rich constellation Sagittarius. About 5,000 light-years away, the colorful study in cosmic contrasts shares this well-composed, nearly 1 degree wide field with open star cluster Messier 21 (right).
APOD: 2020 August 5 B Picture Rocks Sun Dagger
4.08.2020
Ancient sun daggers will not hurt you, but they may tell you the time.b A sun dagger is a dagger-shaped gap in a shadow created by sunlight streaming throughba crevice in a nearby rock.
APOD: 2020 August 4 B NGC 2442: Galaxy in Volans
3.08.2020
Distorted galaxy NGC 2442 can be found in the southern constellation of the flying fish, (Piscis) Volans. Located about 50 million light-years away, the galaxy's two spiral arms extending from a pronounced central bar have a hook-like appearance in wide-field images.
APOD: 2020 August 3 B Comet NEOWISE over Vikos Gorge
2.08.2020
Did the Earth part to show us this comet? Of course not, even if this image makes it seem that way. Pictured far in the background is Comet NEOWISE as it appeared about two weeks ago over northern Greece.
APOD: 2020 August 2 B Two Worlds One Sun
1.08.2020
How different does sunset appear from Mars than from Earth? For comparison, two images of our common star were taken at sunset, one from Earth and one from Mars. These images were scaled to have same angular width and featured here side-by-side.
The Elephant's Trunk Nebula in Cepheus
31.07.2020
Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission nebula and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Also known as vdB 142, the cosmic elephant's trunk is over 20 light-years long.
Mars 2020 from 5,000 Feet
30.07.2020
On Thursday this snapshot from a small plane 5,000 feet above Florida's Space Coast caught a rocket's trail rising into the blue morning sky. It was July's third launch of a mission from planet Earth bound for Mars.
The Red Planet Mars
29.07.2020
Mars looks pretty sharp in this backyard telescope image captured on July 23 from Hoegaarden, Belgium, planet Earth. The Red Planet's bright south polar cap is bathed in sunlight at the top of the inverted view, while the dark feature known as Syrtis Major extends toward the right (eastern) edge.
The Giants of Summer
28.07.2020
As Comet NEOWISE sweeps through northern summer skies, Jupiter and Saturn are shining brightly, near opposition. With Jupiter opposite the Sun on July 14 and Saturn on July 21, the giant planets are still near their closest to planet Earth in 2020.
APOD: 2020 July 28 B NGC 6188: The Dragons of Ara
27.07.2020
Dark shapes with bright edges winging their way through dusty NGC 6188 are tens of light-years long. The emission nebula is found near the edge of an otherwise dark and large molecular cloud in the southern constellation Ara, about 4,000 light-years away.
