Astronomy Picture Of the Day (APOD)
APOD: 2024 January 23 B Deep Nebulas: From Seagull to California
23.01.2024
How well do you know the night sky? OK, but how well can you identify famous sky objects in a very deep image? Either way, here is a test: see if you can find some well-known night-sky icons in a deep image filled with faint nebulosity.
APOD: 2024 January 22 B Shadows of Mountain and Moon
22.01.2024
Can the Moon and a mountain really cast similar shadows? Yes, but the division between light and dark does not have to be aligned. Pictured, a quarter moon was captured above the mountain Grivola in Italy in early October of 2022.
APOD: 2024 January 21 B The Upper Michigan Blizzard of 1938
21.01.2024
Yes, but can your blizzard do this? In the Upper Peninsula of Michigan's Storm of the Century in 1938, some snow drifts reached the level of utility poles. Nearly a meter of new and unexpected snow fell over two days in a storm that started 86 years ago this week.

Jupiter over 2 Hours and 30 Minutes
19.01.2024
Jupiter, our Solar System's ruling gas giant, is also the fastest spinning planet, rotating once in less than 10 hours. The gas giant doesn't rotate like a solid body though.
Northern Lights from the Stratosphere
18.01.2024
Northern lights shine in this night skyview from planet Earth's stratosphere, captured on January 15. The single, 5 second exposure was made with a hand-held camera on board an aircraft above Winnipeg, Canada. During the exposure, terrestrial lights below leave colorful trails along the direction of motion of the speeding aircraft.
America and the Sea of Serenity
17.01.2024
Get out your red/blue glasses and check out this stereo view of another world. The scene was recorded by Apollo 17 mission commander Eugene Cernan on December 11, 1972, one orbit before descending to land on the Moon.
APOD: 2024 January 16 B The Orion You Can Almost See
16.01.2024
Do you recognize this constellation? Although it is one of the most recognizable star groupings on the sky, this is a more full Orion than you can see -- an Orion only revealed with long exposure digital camera imaging and post- processing.
APOD: 2024 January 15 B Star Cluster IC 348 from Webb
15.01.2024
Sometimes, it's the stars that are the hardest to see that are the most interesting. IC 348 is a young star cluster that illuminates surrounding filamentary dust. The stringy and winding dust appears pink in this recently released infrared image from the Webb Space Telescope.
APOD: 2024 January 14 B Dragon Aurora over Iceland
14.01.2024
