Astronomy Picture Of the Day (APOD)
Shackleton from ShadowCam
5.05.2023
Shackleton crater lies at the lunar south pole. Peaks along the 21 kilometer diameter are in sunlight, but Shackleton's floor is in dark permanent shadow. Still, this image of the shadowed rim wall...
The Galaxy, the Jet, and a Famous Black Hole
4.05.2023
Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured in 2017 by planet Earth's Event Horizon Telescope in the first ever image of a black hole. Giant...
APOD: 2023 May 3 B Centaurus A: A Peculiar Island of Stars
3.05.2023
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
2.05.2023
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
1.05.2023
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
30.04.2023
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
29.04.2023
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
28.04.2023
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
27.04.2023
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
26.04.2023
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...
