APOD: 2025 October 11 Б Manicouagan Impact Crater from Space
11.10.2025 | Астрономическая картинка дня

Orbiting 400 kilometers above Quebec, Canada, planet Earth, the International Space Station Expedition 59 crew captured this snapshot of the broad St. Lawrence River and curiously circular Lake Manicouagan on April 11, 2019. Right of center, the ring-shaped lake is a modern reservoir within the eroded remnant of an ancient 100 kilometer diameter impact crater.

APOD: 2025 October 10 Б 50 Light-years to 51 Pegasi
10.10.2025 | Астрономическая картинка дня

It's only 50 light-years to 51 Pegasi. That star's position is indicated in this snapshot from August 2025, taken on a night with mostly brighter stars visible above the dome at Observatoire de Haute-Provence in France.

APOD: 2025 October 9 Б The Jenga Moon

That big, bright, beautiful Full Moon you watched rise on the night of October 6 was the Harvest Moon. Famed in festival, story, and song, Harvest Moon is just the traditional name of the full moon nearest the time of the northern hemisphere's autumnal equinox. According to lore the name is a fitting one.

APOD: 2025 October 8 Б NGC 7380: The Wizard Nebula
8.10.2025 | Астрономическая картинка дня

What powers are being wielded in the Wizard Nebula? Gravitation strong enough to form stars, and stellar winds and radiations powerful enough to create and dissolve towers of gas. Located only 8,000 light years away, the Wizard nebula, featured here, surrounds a developing open star cluster NGC 7380.

APOD: 2025 October 7 Б SN Encore: A Second Supernova Seen Several Times
7.10.2025 | Астрономическая картинка дня

Now a second supernova in this same galaxy is repeating. The cause is the gravitational lens effect of a massive foreground cluster of galaxies (MACS J0138) -- it creates multiple images of a perfectly aligned background galaxy (MRG-M0138). What's particularly interesting is that this background galaxy has young stars that keep blowing up.

APOD: 2025 October 6 Б The Changing Ion Tail of Comet Lemmon

How does a comet tail change? It depends on the comet. The ion tail of Comet C/2025 A6 (Lemmon) has been changing markedly, as detailed in the featured image sequenced over six days between September 25 and October 4 (left to right) from Texas, USA.

APOD: 2025 October 5 Б A Long Storm System on Saturn
5.10.2025 | Астрономическая картинка дня

It was one of the largest and longest lived storms ever recorded in our Solar System. First seen in late 2010, the featured cloud formation in the northern hemisphere of Saturn started larger than the Earth and soon spread completely around the planet.

APOD: 2025 October 4 Б The Rotating Moon
4.10.2025 | Астрономическая картинка дня

No one on Earth sees the Moon rotate like this. That's because the Moon is tidally locked in synchronous rotation, showing only one side to denizens of our fair planet. Still, given modern...

APOD: 2025 October 3 Б Pandora's Cluster of Galaxies
3.10.2025 | Астрономическая картинка дня

This deep field mosaicked image presents a stunning view of galaxy cluster Abell 2744 recorded by the James Webb Space Telescope's NIRCam. Also dubbed Pandora's Cluster, Abell 2744 itself appears to be a ponderous merger of three different massive galaxy clusters. It lies some 3.5 billion light-years away, toward the constellation Sculptor.

APOD: 2025 October 2 Б Pluto at Night
2.10.2025 | Астрономическая картинка дня

The night side of Pluto spans this shadowy scene. In the stunning spacebased perspective, the Sun is 4.9 billion kilometers (almost 4.5 light-hours) behind the dim and distant world. It was captured by far flung New Horizons in July of 2015 when the spacecraft was at a range of some 21,000 kilometers from Pluto.
