Astronomy Picture Of the Day (APOD)

Спиральное северное сияние над Исландией APOD: 2023 January 11 Б Spiral Aurora over Iceland

The scene may look like a fantasy, but it's really Iceland. The rock arch is named Gatklettur and located on the island's northwest coast. Some of the larger rocks in the foreground span a meter across. The fog over the rocks is really moving waves averaged over long exposures.

NGC 2264: туманность Конус APOD: 2023 January 10 Б NGC 2264: The Cone Nebula

Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where clouds of gas and dust are sculpted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264.

Хвосты кометы ZTF APOD: 2023 January 9 Б Tails of Comet ZTF

Comet ZTF may become visible to the unaided eye. Discovered early last year, this massive snowball has been brightening as it approaches the Sun and the Earth. C/2022 E3 (ZTF) will be closest...

Происхождение химических элементов APOD: 2023 January 8 Б Where Your Elements Came From

The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen.

Космические станции на низкой околоземной орбите Space Stations in Low Earth Orbit

On January 3, two space stations already illuminated by sunlight in low Earth orbit crossed this dark predawn sky. Moving west to east (left to right) across the composited timelapse image China's Tiangong Space Station traced the upper trail captured more than an hour before the local sunrise.

Лунные часы 2022 года Moon O Clock 2022

The first Full Moon of 2023 is in the sky tonight opposite the Sun at 23:08 UTC. Big and beautiful, the Moon at its brightest phase should be easy to spot. Still...

Мессье 45: дочери Атласа и Плейоны Messier 45: The Daughters of Atlas and Pleione

Hurtling through a cosmic dust cloud a mere 400 light-years away, the lovely Pleiades or Seven Sisters open star cluster is well-known for its striking blue reflection nebulae. It lies in the night sky toward the constellation Taurus and the Orion Arm of our Milky Way galaxy.

CG4: глобула и галактика APOD: 2023 January 4 Б CG4: The Globule and the Galaxy

Can a gas cloud eat a galaxy? It's not even close. The "claw" of this odd looking "creature" in the featured photo is a gas cloud known as a cometary globule. This globule, however, has ruptured. Cometary globules are typically characterized by dusty heads and elongated tails.

Каскад Кембла APOD: 2023 January 3 Б Kembles Cascade of Stars

This line of stars is real. A little too faint to see with the unaided eye, KembleБs Cascade of stars inspires awe when seen with binoculars. Like the Big Dipper though, KembleБs Cascade is an asterism, not a constellation. The asterism is visible in the northern sky toward the long-necked constellation of the Giraffe (Camelopardalis).

Парад планет после заката APOD: 2023 January 2 Б After Sunset Planet Parade

Look up tonight and see a whole bunch of planets. Just after sunset, looking west, planets Venus, Saturn, Jupiter and Mars will all be simultaneously visible. Listed west to east, this planetary lineup will have Venus nearest the horizon, but setting shortly after the Sun.
