Astronomy Picture Of the Day (APOD)
APOD: 2023 May 3 B Centaurus A: A Peculiar Island of Stars
2.05.2023
Galaxies are fascinating. In galaxies, gravity alone holds together massive collections of stars, dust, interstellar gas, stellar remnants and dark matter. Pictured is NGC 5128, better known as Centaurus A. Cen A is the fifth brightest galaxy on the sky and is located at a distance of about 12 million light years from Earth.
APOD: 2023 May 2 B Flat Rock Hills on Mars
1.05.2023
Why are there so many flat rocks on Mars? Some views of plains and hills on Mars show many rocks that are unusually flat when compared to rocks on Earth. One reason for this is a process that is common to both Mars and Earth: erosion.
APOD: 2023 May 1 B Carina Nebula North
30.04.2023
The Great Carina Nebula is home to strange stars and iconic nebulas. Named for its home constellation, the huge star-forming region is larger and brighter than the Great Orion Nebula but less well known because it is so far south -- and because so much of humanity lives so far north.
APOD: 2023 April 30 B Saturns Moon Helene in Color
29.04.2023
Although its colors may be subtle, Saturn's moon Helene is an enigma in any light. The moon was imaged in unprecedented detail in 2012 as the robotic Cassini spacecraft orbiting Saturn swooped to within a single Earth diameter of the diminutive moon.
Solar Eclipse from a Ship
28.04.2023
Along a narrow path that mostly avoided landfall, the shadow of the New Moon raced across planet Earth's southern hemisphere on April 20 to create a rare annular-total or hybrid solar eclipse. From...
Runaway Star Alpha Camelopardalis
27.04.2023
Like a ship plowing through cosmic seas, runaway star Alpha Camelopardalis has produced this graceful arcing bow wave or bow shock. The massive supergiant star moves at over 60 kilometers per second through space, compressing the interstellar material in its path.
The Tarantula Nebula from SuperBIT
26.04.2023
The Tarantula Nebula, also known as 30 Doradus, is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud. About 160 thousand light-years away, it's the largest, most violent star forming region known in the whole Local Group of galaxies.
APOD: 2023 April 26 B The Moon through the Arc de Triomphe
25.04.2023
Was this a lucky shot? Although many amazing photographs are taken by someone who just happenedbto be in the right place at the right time, this image took skill and careful planning. First...
APOD: 2023 April 25 B Northern Lights over Southern Europe
24.04.2023
Did you see an aurora over the past two nights? Many people who don't live in Earth's far north did. Reports of aurora came in not only from northern locales in the USA as Alaska, but as far south as Texas and Arizona. A huge auroral oval extended over Europe and Asia, too.
APOD: 2023 April 24 B The Medulla Nebula Supernova Remnant
23.04.2023
What powers this unusual nebula? CTB-1 is the expanding gas shell that was left when a massive star toward the constellation of Cassiopeia exploded about 10,000 years ago. The star likely detonated when it ran out of elements near its core that could create stabilizing pressure with nuclear fusion.
