Astronomy Picture Of the Day (APOD)
The Medusa Nebula21.11.2024
Braided and serpentine filaments of glowing gas suggest this nebula's popular name, The Medusa Nebula. Also known as Abell 21, this Medusa is an old planetary nebula some 1,500 light-years away in the constellation Gemini. Like its mythological namesake, the nebula is associated with a dramatic transformation.
The Elephant s Trunk in Cepheus
20.11.2024
Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission region and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Also known as vdB 142, this cosmic elephant's trunk is over 20 light-years long.
Earthset from Orion
19.11.2024
Eight billion people are about to disappear in this snapshot from space taken on 2022 November 21. On the sixth day of the Artemis I mission, their home world is setting behind the Moon's bright edge as viewed by an external camera on the outbound Orion spacecraft.
APOD: 2024 November 19 Б Undulatus Clouds over Las Campanas Observatory
18.11.2024
What's happening with these clouds? While it may seem that these long and thin clouds are pointing toward the top of a hill, and that maybe a world-famous observatory is located there, only part of that is true.
APOD: 2024 November 18 Б Stars and Dust in the Pacman Nebula
17.11.2024
Stars can create huge and intricate dust sculptures from the dense and dark molecular clouds from which they are born. The tools the stars use to carve their detailed works are high energy light and fast stellar winds.
APOD: 2024 November 17 Б LDN 1471: A Windblown Star Cavity
16.11.2024
What is the cause of this unusual parabolic structure? This illuminated cavity, known as LDN 1471, was created by a newly forming star, seen as the bright source at the peak of the parabola.
Pluto at Night
15.11.2024
The night side of Pluto spans this shadowy scene. In the stunning spacebased perspective the Sun is 4.9 billion kilometers (almost 4.5 light-hours) behind the dim and distant world. It was captured...
Apollo 12 and Surveyor 3
14.11.2024
Put on your red/blue glasses and gaze across the western Ocean of Storms on the surface of the Moon. The 3D anaglyph features Apollo 12 astronaut Pete Conrad visiting the Surveyor 3 spacecraft in November of 1969.
IC 348 and Barnard 3
13.11.2024
A great nebulous region near bright star omicron Persei offers this study in cosmic contrasts. Captured in the telescopic frame the colorful complex of dust, gas, and stars spans about 3 degrees on the sky along the edge of the Perseus molecular cloud some 1000 light-years away.
Barred Spiral Galaxy NGC 1365 from Webb
12.11.2024
A mere 56 million light-years distant toward the southern constellation Fornax, NGC 1365 is an enormous barred spiral galaxy about 200,000 light-years in diameter. That's twice the size of our own barred spiral Milky Way.
