Astronomy Picture Of the Day (APOD)
APOD: 2025 November 30 Б The Surface of Titan from Huygens
29.11.2025
If you could stand on Titan -- what would you see? The featured color viewa from Titan gazes across an unfamiliar and distant landscape on Saturn's largest moon. The scene was recorded by ESA's Huygens probe in 2005 after a 2.5-hour descent through a thick atmosphere of nitrogen laced with methane.
Moon Games
28.11.2025
This is not a screen from a video game. Nestled below the tree-line, the small mountain church does look like it might be hiding from Moon though. In the well-composed telephoto snapshot, taken on November 23, the church walls are partly reflecting light from terrestrial flood lights.
NGC 6888: The Crescent Nebula
27.11.2025
NGC 6888, also known as the Crescent Nebula, is a about 25 light-years across, a cosmic bubble blown by winds from its central, massive star. This deep telescopic image includes narrowband image data, to isolate light from hydrogen and oxygen atoms.
Portrait of NGC 1055
26.11.2025
Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way galaxy.
APOD: 2025 November 26 Б Globular Cluster M15 Deep Field
25.11.2025
Stars, like bees, swarm around the center of bright globular cluster M15. The central ball of over 100,000 stars is a relic from the early years of our Galaxy, and continues to orbit the Milky Way's center.
APOD: 2025 November 25 Б Comet Lemmon and the Milky Way
24.11.2025
What did Comet Lemmon look like when it was at its best? One example is pictured here, featuring three celestial spectacles all at different distances. The closest spectacle is the snowcapped Meili Mountains, part of the Himalayas in China.
APOD: 2025 November 24 Б Apep: Unusual Dust Shells from Webb
23.11.2025
What created this unusual space sculpture? Stars. This unusual system of swirls and shells, known as Apep, was observed in unprecedentedбdetail by NASAБs James Webb Space Telescope in infrared light in 2024. Observations indicate...
APOD: 2025 November 23 Б The Observable Universe
22.11.2025
How far can you see? Everything you can see, and everything you could possibly see, right now, assuming your eyes could detect all types of radiations around you -- is the observable universe. In light...
Dione and Rhea Ring Transit
21.11.2025
Seen to the left of Saturn's banded planetary disk, small icy moons Dione and Rhea are caught passing in front of the gas giant's extensive ring system in this sharp telescopic snapshot. The remarkable image was recorded on November 20, when Saturn's rings were nearly edge-on when viewed from planet Earth.
3I/ATLAS: A View from Planet Earth
20.11.2025
Now outbound after its perihelion or closest approach to the Sun on October 29, Comet 3I/ATLAS is only the third known interstellar object to pass through our fair Solar System. Its greenish coma...
