Astronomy Picture Of the Day (APOD)
APOD: 2024 October 8 Á Annular Eclipse over Patagonia
8.10.2024
Can you find the Sun? OK, but can you explain why thereÁs 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 Á The Long Tails of Comet Tsuchinshan ATLAS
7.10.2024
A bright comet is moving into the evening skies. C/2023 A3 (TsuchinshanÁATLAS) 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 TsuchinshanÁATLAS was captured just before sunrise from an Andes Mountain in Peru.
APOD: 2024 October 6 Á The Magnificent Tail of Comet McNaught
6.10.2024
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.
M27: Not a Comet
5.10.2024
While hunting for comets in the skies above 18th century France, astronomer Charles Messier diligently kept a list of the things encountered during his telescopic expeditions that were definitely not comets. This is number 27 on his now famous not-a-comet list.
Comet at Moonrise
4.10.2024
Comet C/2023 A3 (TsuchinshanÁATLAS) is growing brighter in planet Earth's sky. Fondly known as comet A3, this new visitor to the inner Solar System is traveling from the distant Oort cloud. The comet...
Eclipse at Sunrise
3.10.2024
The second solar eclipse of 2024 began in the Pacific. On October 2nd the Moon's shadow swept from west to east, with an annular eclipse visible along a narrow antumbral shadow path tracking mostly over ocean, crossing land near the southern tip of South America, and ending in the southern Atlantic.
APOD: 2024 October 2 Á The Large Magellanic Cloud Galaxy
2.10.2024
It is the largest satellite galaxy of our home Milky Way Galaxy. If you live in the south, the Large Magellanic Cloud (LMC) is quite noticeable, spanning about 10 degrees across the night sky, which is 20 times larger than the full moon towards the southern constellation of the dolphinfish (Dorado).
APOD: 2024 October 1 Á Porphyrion: The Longest Known Black Hole Jets
1.10.2024
How far can black hole jets extend? A new record was found just recently with the discovery of a 23-million light-year long jet pair from a black hole active billions of years ago. Dubbed...
APOD: 2024 September 30 Á Comet Tsuchinshan ATLAS over Mexico
30.09.2024
The new comet has passed its closest to the Sun and is now moving closer to the Earth. C/2023 A3 (TsuchinshanÁATLAS) is currently moving out from inside the orbit of Venus and on track to pass its nearest to the Earth in about two weeks.
APOD: 2024 September 29 Á Seven Dusty Sisters
29.09.2024
Is this really the famous Pleiades star cluster? Known for its iconic blue stars, the Pleiades is shown here in infrared light where the surrounding dust outshines the stars. Here, three infrared colors have been mapped into visual colors (R=24, G=12, B=4.6 microns).
