Astronomy Picture Of the Day (APOD)
APOD: 2025 August 30 B A Two Percent Moon
29.08.2025
A young crescent moon can be hard to see. That's because when the Moon shows it's crescent phase (young or old) it can never be far from the Sun in planet Earth's sky.
APOD: 2025 August 29 B A Dark Veil in Ophiuchus
28.08.2025
The diffuse hydrogen-alpha glow of emission region Sh2-27 fills this cosmic scene. The field of view spans nearly 3 degrees across the nebula-rich constellation Ophiuchus toward the central Milky Way. A Dark Veil...
APOD: 2025 August 28 B Galaxies, Stars, and Dust
27.08.2025
This well-composed telescopic field of view covers over a Full Moon on the sky toward the high-flying constellation Pegasus. Of course the brighter stars show diffraction spikes, the commonly seen effect of internal supports in reflecting telescopes, and lie well within our own Milky Way galaxy.
APOD: 2025 August 27 B WISPIT 2b: Exoplanet Carves Gap in Birth Disk
26.08.2025
That yellow spot -- what is it? It's a young planet outside our Solar System. The featured image from the Very Large Telescope in Chile surprisingly captures a distant scene much like our own Solar System's birth, some 4.5 billion years ago.
APOD: 2025 August 25 B The Meteor and the Star Cluster
24.08.2025
Sometimes even the sky surprises you. To see more stars and faint nebulosity in the Pleiades star cluster (M45), long exposures are made. Many times, less interesting items appear on the exposures that were not intended -- but later edited out.
APOD: 2025 August 24 B The Spinning Pulsar of the Crab Nebula
23.08.2025
At the core of the Crab Nebula lies a city-sized, magnetized neutron star spinning 30 times a second. Known as the Crab Pulsar, it is the bright spot in the center of the gaseous swirl at the nebula's core.
APOD: 2025 August 23 B Fishing for the Moon
22.08.2025
How big is planet Earth's Moon? Compared to other moons of the Solar System, it's number 5 on the largest to smallest ranked list, following Jupiter's moon Ganymede, Saturn's moon Titan, and Jovian moons Callisto and Io. Continuing the list, the Moon comes before Jupiter's Europa and Neptune's Triton.
APOD: 2025 August 22 B A Tale of Two Nebulae
21.08.2025
This colorful telescopic view towards the musical northern constellation Lyra reveals the faint outer halos and brighter central ring-shaped region of M57, popularly known as the Ring Nebula. To modern astronomers M57 is a well-known planetary nebula.
APOD: 2025 August 21 B Mostly Perseids
20.08.2025
In this predawn skyscape recorded during the early morning hours of August 13, mostly Perseid meteors are raining down on planet Earth. You can easily identify the Perseid meteor streaks. They're the ones...
APOD: 2025 August 20 B Perseid Meteors from Durdle Door
19.08.2025
What are those curved arcs in the sky? Meteors -- specifically, meteors from this year's Perseid meteor shower. Over the past few weeks, after the sky darkened, many images of Perseid meteors were captured separately and merged into a single frame, taken earlier.
