Astronomy Picture Of the Day (APOD)
Full Observatory Moon
26.01.2024
A popular name for January's full moon in the northern hemisphere is the Full Wolf Moon. As the new year's first full moon, it rises over Las Campanas Observatory in this dramatic Earth-and-moonscape. Peering from the foreground like astronomical eyes are the observatory's twin 6.5 meter diameter Magellan telescopes.
Epsilon Tauri: Star with Planet
25.01.2024
Epsilon Tauri lies 146 light-years away. A K-type red giant star, epsilon Tau is cooler than the Sun, but with about 13 times the solar radius it has nearly 100 times the solar luminosity.
Jyvcskylc in the Sky
24.01.2024
You might not immediately recognize this street map of a neighborhood in Jyvcskylc, Finland, planet Earth. But that's probably because the map was projected into the night sky and captured with an allsky camera on January 16. The temperature recorded on that northern winter night was around minus 20 degrees Celsius.
APOD: 2024 January 24 B Earth and Moon from Beyond
23.01.2024
What do the Earth and Moon look like from beyond the Moon? Although frequently photographed together, the familiar duo was captured with this unusual perspective in late 2022 by the robotic Orion spacecraft of NASA's Artemis I mission as it looped around Earth's most massive satellite and looked back toward its home world.
APOD: 2024 January 23 B Deep Nebulas: From Seagull to California
22.01.2024
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
21.01.2024
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
20.01.2024
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.
Falcon Heavy Boostback Burn
19.01.2024
The December 28 night launch of a Falcon Heavy rocket from Kennedy Space Center in Florida marked the fifth launch for the rocket's reusable side boosters. About 2 minutes 20 seconds into the flight, the two side boosters separated from the rocket's core stage.
Jupiter over 2 Hours and 30 Minutes
18.01.2024
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
17.01.2024
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.
