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 (TsuchinshanБATLAS) 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 Б 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 Б 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 Б 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 (TsuchinshanБATLAS) 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 Б 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).
Rocket Eclipse at Sunset
28.09.2024
Shockwaves ripple across the glare as a launch eclipses the setting Sun in this exciting close-up. Captured on September 17, the roaring Falcon 9 rocket carried European Galileo L13 navigation satellites to medium Earth orbit after a lift-off from Cape Canaveral on Florida's space coast.
Stellar Streams in the Local Universe
27.09.2024
The twenty galaxies arrayed in these panels are part of an ambitious astronomical survey of tidal stellar streams. Each panel presents a composite view; a deep, inverted image taken from publicly available imaging surveys of a field that surrounds a nearby massive galaxy image.
The Great Globular Cluster in Hercules

In 1716, English astronomer Edmond Halley noted, "This is but a little Patch, but it shows itself to the naked Eye, when the Sky is serene and the Moon absent." Of course...
