Astronomy Picture Of the Day (APOD)
APOD: 2023 July 24 B Chemicals Glow as a Meteor Disintegrates
24.07.2023
Meteors can be colorful. While the human eye usually cannot discern many colors, cameras often can. Pictured here is a fireball, a disintegrating meteor that was not only one of the brightest the photographer has ever seen, but colorful.
APOD: 2023 July 23 B The Antikythera Mechanism
23.07.2023
It does what? No one knew that 2,000 years ago, the technology existed to build such a device. The Antikythera mechanism, pictured, is now widely regarded as the first computer. Found...
Apollo 11: Armstrong's Lunar Selfie
22.07.2023
A photograph of Buzz Aldrin standing on the Moon taken by Neil Armstrong, was digitally reversed to create this lunar selfie. Captured in July 1969 following the Apollo 11 moon landing, Armstrong's original photograph recorded not only the magnificent desolation of an unfamiliar world, but Armstrong himself reflected in Aldrin's curved visor.
Galactic Cirrus: Mandel Wilson 9
21.07.2023
The combined light of stars along the Milky Way are reflected by these cosmic dust clouds that soar 300 light-years or so above the plane of our galaxy. Known to some as integrated flux nebulae and commonly found at high galactic latitudes, the dusty galactic cirrus clouds are faint.
M64: The Black Eye Galaxy
20.07.2023
This magnificent spiral galaxy is Messier 64, often called the Black Eye Galaxy or the Sleeping Beauty Galaxy for its dark-lidded appearance in telescopic views. The spiral's central region, about 7,400 light-years across, is pictured in this reprocessed image from the Hubble Space Telescope.
APOD: 2023 July 19 B Chandrayaan 3 Launches to the Moon
19.07.2023
Birds don't fly this high. Airplanes don't go this fast. The Statue of Liberty weighs less. No species other than human can even comprehend what is going on, nor could any human just a millennium ago. The launch of a rocket bound for space is an event that inspires awe and challenges description.
APOD: 2023 July 18 B Milky Way above La Palma Observatory
18.07.2023
What's happening in the night sky? To help find out, telescopes all over the globe will be pointing into deep space. Investigations will include trying to understand the early universe, finding and tracking Earth-menacing asteroids, searching for planets that might contain extra-terrestrial life, and monitoring stars to help better understand our Sun.
APOD: 2023 July 17 B Shells and Arcs around Star CW Leonis
17.07.2023
What's happening around this star? No one is sure. CW Leonis is the closest carbon star, a star that appears orange because of atmospheric carbon dispersed from interior nuclear fusion. But CW Leonis also appears engulfed in a gaseous carbon-rich nebula.
APOD: 2023 July 16 B Meteor and Milky Way over the Alps
16.07.2023
Now this was a view with a thrill. From Mount Tschirgant in the Alps, you can see not only nearby towns and distant Tyrolean peaks, but also, weather permitting, stars, nebulas, and the band of the Milky Way Galaxy.
Webb's First Deep Field
15.07.2023
This stunning infrared image was released one year ago as the James Webb Space Telescope began its exploration of the cosmos. The view of the early Universe toward the southern constellation Volans was achieved in 12.5 hours of exposure with Webb's NIRCam instrument.
