APOD: 2024 October 13 Б Aurora Timelapse Over Italian Alps
12.10.2024
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
11.10.2024
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.
Ring of Fire over Easter Island

APOD: 2024 October 8 Б Annular Eclipse over Patagonia

Can you find the Sun? OK, but can you explain why thereБs a big dark spot in the center? The spot is the Moon, and the impressive alignment shown, where the Moon lines up inside the Sun, is called an annular solar eclipse.
APOD: 2024 October 7 Б The Long Tails of Comet Tsuchinshan ATLAS
6.10.2024
A bright comet is moving into the evening skies. C/2023 A3 (TsuchinshanБATLAS) has brightened and even though it is now easily visible to the unaided eye, it is so near to the Sun that it is still difficult to see. Pictured, Comet TsuchinshanБATLAS was captured just before sunrise from an Andes Mountain in Peru.
APOD: 2024 October 6 Б The Magnificent Tail of Comet McNaught
5.10.2024
Comet McNaught, the Great Comet of 2007, grew a spectacularly long and filamentary tail. The magnificent tail spread across the sky and was visible for several days to Southern Hemisphere observers just after sunset. The amazing ion tail showed its greatest extent on long-duration, wide-angle camera exposures.
