Astronomy Picture Of the Day (APOD)
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.
APOD: 2023 April 23 B A Waterspout in Florida
22.04.2023
What's happening over the water? Pictured here is one of the better images yet recorded of a waterspout, a type of tornado that occurs over water. Waterspouts are spinning columns of rising moist air that typically form over warm water.
NGC 1333: Stellar Nursery in Perseus
21.04.2023
In visible light NGC 1333 is seen as a reflection nebula, dominated by bluish hues characteristic of starlight reflected by interstellar dust. A mere 1,000 light-years distant toward the heroic constellation Perseus, it lies at the edge of a large, star-forming molecular cloud.
Solar Eclipse from Western Australia
20.04.2023
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.
