Astronomy Picture Of the Day (APOD)
Crescent Enceladus
7.02.2026
Peering from the shadows, the Saturn-facing hemisphere of tantalizing inner moon Enceladus poses in this Cassini spacecraft image. North is up in the dramatic scene captured during November 2016 as Cassini's camera was pointed in a nearly sunward direction about 130,000 kilometers from the moon's bright crescent.
Supernova Remnant Cassiopeia A
6.02.2026
Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After only a few million years for the most massive stars, the enriched material is blasted back into interstellar space where star formation can begin anew.
NGC 1275 in the Perseus Cluster
5.02.2026
Active galaxy NGC 1275 is the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a prodigious source of x-rays and radio emission.
APOD: 2026 February 4 Б Spiral Galaxy NGC 1512: Wide Field
4.02.2026
Most galaxies don't have any rings -- why does this galaxy have three? To begin, a ring that's near NGC 1512's center -- and so hard to see here -- is the nuclear ring which glows brightly with recently formed stars.
APOD: 2026 February 3 Б Red Spider Planetary Nebula from Webb
3.02.2026
Oh what a tangled web a planetary nebula can weave. The Red Spider Planetary Nebula shows the complex structure that can result when a normal star ejects its outer gases and becomes a white dwarf star.
APOD: 2026 February 2 Б Orion: The Running Man Nebula
2.02.2026
What part of Orion is this? Just north of the famous Orion Nebula is a picturesque star forming region in Orion's Sword that contains a lot of intricate dust -- some of which appears blue because it reflects the light of bright embedded stars.
APOD: 2026 February 1 Б Galle: Happy Face Crater on Mars
1.02.2026
Mars has put on a happy face. The Martian crater Galle is famous because it has internal markings that make it look like a face that is both smiling and winking. These markings were originally discovered in the 1970s in pictures taken by the Viking Orbiter.
Artemis I: Flight Day 13
31.01.2026
On flight day 13 (November 28, 2022) of the Artemis 1 mission, the Orion spacecraft reached its maximum distance from Earth. At over 430,000 kilometers from Earth, its distant retrograde orbit also puts Orion nearly 70,000 kilometers from the Moon.
NGC 1333: Stellar Nursery in Perseus
30.01.2026
NGC 1333 is seen in visible light 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.
NGC 2442: Galaxy in Volans
29.01.2026
Distorted galaxy NGC 2442 can be found in the southern constellation of the flying fish, (Piscis) Volans. Located about 50 million light-years away, the galaxy's two spiral arms extending from a pronounced central...
