APOD: 2025 October 29 Б Dust Shapes of the Ghost Nebula
29.10.2025 | Астрономическая картинка дня

Do any shapes seem to jump out at you from this interstellar field of stars and dust? The jeweled expanse, filled with faint, starlight-reflecting clouds, drifts through the night in the royal constellation of Cepheus.

APOD: 2025 October 28 Б NGC 6995: The Bat Nebula
28.10.2025 | Астрономическая картинка дня

Can you see the bat? It haunts this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star.

APOD: 2025 October 27 Б Two Tails of Comet Lemmon
27.10.2025 | Астрономическая картинка дня

How many bright tails does Comet Lemmon have? Two. In the featured image it appears to have three, but why? The reason is that the zigzagging brown filament is a persistent meteor train that by luck appeared in front of the distant comet C/2025 A6 (Lemmon).

APOD: 2025 October 26 Б Halloween and the Ghost Head Nebula
26.10.2025 | Астрономическая картинка дня

Halloween's origin is ancient and astronomical. Since the fifth century BC, Halloween has been celebrated as a cross-quarter day, a day halfway between an equinox (equal day / equal night) and a solstice (minimum day / maximum night in the northern hemisphere).

Webb's Rho Ophiuchi
25.10.2025 | Астрономическая картинка дня

A mere 390 light-years away, Sun-like stars and future planetary systems are forming in the Rho Ophiuchi molecular cloud complex, the closest star-forming region to our fair planet. The James Webb Space Telescope's NIRCam peered into the nearby natal chaos to capture this infrared image at an inspiring scale.

Saturn at Night
24.10.2025 | Астрономическая картинка дня

Saturn is bright in Earth's night skies. Telescopic views of the outer gas giant planet and its beautiful rings often make it a star at star parties. But this stunning view of Saturn's rings and night side just isn't possible from telescopes in the vicinity of planet Earth.

SWAN, Swan, Eagle
23.10.2025 | Астрономическая картинка дня

Comet C/2025 R2 (SWAN) sports a greenish coma and fainter tail, seen against congeries of stars and dusty interstellar clouds in this 7 degree wide telescopic field of view from October 17. On that...

APOD: 2025 October 22 Б Comet Lemmon over the High Tatras
22.10.2025 | Астрономическая картинка дня

Comet Lemmon putting on a show for cameras around the globe. Passing nearest to the Earth this week, the photogenic comet C/2025 A6 (Lemmon) is now extending two long tails : a blue ion tail and a white dust tail.

APOD: 2025 October 21 Б IC 1805: The Heart Nebula
21.10.2025 | Астрономическая картинка дня

What electrifies the Heart Nebula? First, the large emission nebula on the left, catalogued as IC 1805, looks somewhat like a human heart. The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by sulfur (yellow) and oxygen (blue).

APOD: 2025 October 20 Б Finding Comet Lemmon
20.10.2025 | Астрономическая картинка дня

Tonight, if you can see the stars of the Big Dipper, then you can find comet Lemmon in your evening sky. After sunset, look for the faint but extended comet above your northwestern horizon -- but below the handle of the famous celestial kitchen utensil of the north.
