Astronomy Picture Of the Day (APOD)
Periodic Comet Swift Tuttle
7.08.2024
A Halley-type comet with an orbital period of about 133 years, Comet 109P/Swift-Tuttle is recognized as the parent of the annual Perseid Meteor Shower. The comet's last visit to the inner Solar System was in 1992.
APOD: 2024 August 7 Б Milky Way Behind Three Merlons
6.08.2024
To some, they look like battlements, here protecting us against the center of the Milky Way. The Three Merlons, also called the Three Peaks of Lavaredo, stand tall today because they are made of dense dolomite rock which has better resisted erosion than surrounding softer rock.
APOD: 2024 August 6 Б Storm Cloud Over Texas
5.08.2024
What makes this storm cloud so colorful? First, the cloud itself is composed of millions of tiny droplets of water and ice. Its bottom is almost completely flat -- but this isn't unusual. Bottom...
APOD: 2024 August 5 Б Milky Way Over Tunisia
4.08.2024
That's no moon. On the ground, that's the Lars Homestead in Tunisia. And that's not just any galaxy. That's the central band of our own Milky Way galaxy. Last, that's not just any meteor. It is a bright fireball likely from last year's Perseids meteor shower.
APOD: 2024 August 4 Б Gaia: Here Comes the Sun
3.08.2024
What would it look like to return home from outside our galaxy? Although designed to answer greater questions, data from ESA's robotic Gaia mission is helping to provide a uniquely modern perspective on humanity's place in the universe.
Glory and Fog Bow
2.08.2024
On a road trip up Mount Uludaд in Bursa province, Turkey these motorcyclists found themselves above low clouds and fog in late June. With the bright Sun directly behind them, the view down the side of the great mountain revealed a beautiful, atmospheric glory and fog bow.
Mars Passing By
1.08.2024
As Mars wanders through Earth's night, it passes about 5 degrees south of the Pleiades star cluster in this composite astrophoto. The skyview was constructed from a series of images captured over a run of 16 consecutive clear nights beginning on July 12.
Comet Olbers over Kunetice Castle
31.07.2024
A visitor to the inner solar system every 70 years or so Comet 13P/Olbers reached its most recent perihelion, or closest approach to the Sun, on June 30 2024. Now on a return voyage...
APOD: 2024 July 31 Б Leopard Spots on Martian Rocks
30.07.2024
What is creating these unusual spots? Light-colored spots on Martian rocks, each surrounded by a dark border, were discovered earlier this month by NASA's Perseverance Rover currently exploring Mars. Dubbed leopard spots because...
APOD: 2024 July 30 Б Arp 142: Interacting Galaxies from Webb
29.07.2024
To some, it looks like a penguin. But to people who study the universe, it is an interesting example of two big galaxies interacting. Just a few hundred million years ago, the upper NGC 2936 was likely a normal spiral galaxy: spinning, creating stars, and minding its own business.
