APOD: 2026 April 27 Б Comet R3 PanSTARRS Behind Satellite Trails
27.04.2026

Can you find the comet? Somewhere through this web of satellite trails is Comet C/2025 R3 (PanSTARRS), a bright visitor passing through the inner Solar System. Now, the orbiting satellites themselves only appear as streaks because of the long camera exposure, over 10 minutes in this case.

APOD: 2025 June 11 Б 25 Brightest Stars in the Night Sky
11.06.2025

Do you know the names of some of the brightest stars? It's likely that you do, even though some bright stars have names so old they date back to near the beginning of written language.

APOD: 2024 November 3 Б Jupiter Abyss
3.11.2024

What's that black spot on Jupiter? No one is sure. During one pass of NASA's Juno over Jupiter, the robotic spacecraft imaged an usually dark cloud feature informally dubbed the Abyss. Surrounding cloud patterns show the Abyss to be at the center of a vortex.

APOD: 2025 May 9 Б IXPE Explores a Black Hole Jet
9.05.2025

How do black holes create X-rays? Answering this long-standing question was significantly advanced recently with data taken by NASAБs IXPE satellite. X-rays cannot exit a black hole, but they can be created in the energetic environment nearby, in particular by a jet of particles moving outward.

APOD: 2025 June 19 Б NGC 3521: Galaxy in a Bubble
19.06.2025

Gorgeous spiral galaxy NGC 3521 is a mere 35 million light-years away, toward the northern springtime constellation Leo. Relatively bright in planet Earth's sky, NGC 3521 is easily visible in small telescopes but often overlooked by amateur imagers in favor of other Leo spiral galaxies, like M66 and M65.

APOD: 2025 September 14 Б Planets of the Solar System: Tilts and Spins
14.09.2025

How does your favorite planet spin? Does it spin rapidly around a nearly vertical axis, or horizontally, or backwards? The featured video animates NASA images of all eight planets in our Solar System to show them spinning side-by-side for an easy comparison.

APOD: 2026 April 01 Б The Claw and Bubble Nebulae
1.04.2026

What unexpected things do you see when you look up at the night sky? TodayБs image resembles an abstract painting, with large swaths of color strewn across a cosmic canvas seemingly without design. Despite the image's abstract nature, the human mind finds patterns, identifying a large claw reaching up towards a floating bubble.

APOD: 2023 March 15 Б Jupiter and Venus Converge over Germany
15.03.2023

This was a sky to show the kids. Early this month the two brightest planets in the night sky, Jupiter and Venus, appeared to converge. At their closest, the two planets were separated by only about the angular width of the full moon.

APOD: 2024 May 29 Б Stairway to the Milky Way
29.05.2024

What happens if you ascend this stairway to the Milky Way? Before answering that, let's understand the beautiful sky you will see. Most eye-catching is the grand arch of the Milky Way Galaxy...

APOD: 2025 April 15 Б Planetary Nebula NGC 1514 from Webb
15.04.2025

What happens when a star runs out of nuclear fuel? For stars like our Sun, the center condenses into a white dwarf while the outer atmosphere is expelled into space to appear as a planetary nebula.
