Astronomy Picture Of the Day (APOD)
APOD: 2024 September 30 Б Comet Tsuchinshan ATLAS over Mexico30.09.2024
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
26.09.2024
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...
APOD: 2024 September 25 Б Comet A3 Through an Australian Sunrise
25.09.2024
Comet Tsuchinshan-ATLAS is now visible in the early morning sky. Diving into the inner Solar System at an odd angle, this large dirty iceberg will pass its closest to the Sun -- between the orbits of Mercury and Venus -- in just two days.
APOD: 2024 September 24 Б NGC 6727: The Rampaging Baboon Nebula
24.09.2024
This dusty region is forming stars. Part of a sprawling molecular cloud complex that resembles, to some, a rampaging baboon, the region is a relatively close by 500 light-years away toward the constellation Corona Australis. That's about one third the distance of the more famous stellar nursery known as the Orion Nebula.
APOD: 2024 September 23 Б Comet Tsuchinshan ATLAS Approaches
23.09.2024
What will happen as this already bright comet approaches? Optimistic predictions have Comet C/2023 A3 (TsuchinshanБATLAS) briefly becoming easily visible to the unaided eye -- although the future brightness of comets are notoriously hard to predict, and this comet may even break up in warming sunlight.
APOD: 2024 September 22 Б Chicagohenge: Equinox in an Aligned City
22.09.2024
Chicago, in a way, is like a modern Stonehenge. The way is east to west, and the time is today. Today, and every equinox, the Sun will set exactly to the west, everywhere on Earth.
Sunrise Shadows in the Sky
21.09.2024
The defining astronomical moment of this September's equinox is at 12:44 UTC on September 22, when the Sun crosses the celestial equator moving south in its yearly journey through planet Earth's sky.
