Astronomy Picture Of the Day (APOD)
APOD: 2024 October 21 Б Comet Tsuchinshan ATLAS over California
21.10.2024
The tails of Comet Tsuchinshan-ATLAS were a sight to behold. Pictured, C/2023 A3 (TsuchinshanБATLAS) was captured near peak impressiveness last week over the Eastern Sierra Mountains in California, USA. The comet not only showed a bright tail, but a distinct anti-tail pointing in nearly the opposite direction.
APOD: 2024 October 20 Б Dark Matter in a Simulated Universe
20.10.2024
Is our universe haunted? It might look that way on this dark matter map. The gravity of unseen dark matter is the leading explanation for why galaxies rotate so fast, why galaxies orbit clusters...
Comet Tsuchinshan ATLAS Flys Away
19.10.2024
These six panels follow daily apparitions of comet C/2023 A3 Tsuchinshan-ATLAS as it moved away from our fair planet during the past week. The images were taken with the same camera and lens at the indicated dates and locations from California, planet Earth.
Most of Comet Tsuchinshan ATLAS
18.10.2024
On October 14 it was hard to capture a full view of Comet C/2023 A3 Tsuchinshan-ATLAS. Taken after the comet's closest approach to our fair planet, this evening skyview almost does though. With...
The Clipper and the Comet
17.10.2024
NASA's Europa Clipper is now headed toward an ocean world beyond Earth. The large spacecraft is tucked into the payload fairing atop the Falcon Heavy rocket in this photo, taken at Kennedy Space Center the day before the mission's successful October 14 launch.
APOD: 2024 October 16 Б Colorful Aurora over New Zealand
16.10.2024
Sometimes the night sky is full of surprises. Take the sky over Lindis Pass, South Island, New Zealand one-night last week. Instead of a typically calm night sky filled with constant stars, a busy and dynamic night sky appeared.
APOD: 2024 October 15 Б Animation: Comet Tsuchinshan ATLAS Tails Prediction
15.10.2024
How bright and strange will the tails of Comet Tsuchinshan-ATLAS become? The comet has brightened dramatically over the few weeks as it passed its closest to the Sun and, just three days ago, passed its closest to the Earth.
APOD: 2024 October 14 Б Comet Tsuchinshan ATLAS Over the Lincoln Memorial
14.10.2024
Go outside at sunset tonight and see a comet! C/2023 A3 (TsuchinshanБATLAS) has become visible in the early evening sky in northern locations to the unaided eye. To see the comet, look west through a sky with a low horizon.
APOD: 2024 October 13 Б Aurora Timelapse Over Italian Alps
13.10.2024
Did you see last night's aurora? This question was relevant around much of the world a few days ago because a powerful auroral storm became visible unusually far from the Earth's poles.
Northern Lights, West Virginia
12.10.2024
A gravel country lane gently winds through this colorful rural night skyscape. Captured from Monroe County in southern West Virginia on the evening of October 10, the starry sky above is a familiar sight. Shimmering curtains of aurora borealis or northern lights definitely do not make regular appearances here, though.
