Astronomy Picture Of the Day (APOD)

Моделирование формирования дисковой галактики APOD: 2023 May 31 Б Simulation: A Disk Galaxy Forms

How did we get here? We know that we live on a planet orbiting a star orbiting a galaxy, but how did all of this form? Since our universe moves too slowly to watch, faster-moving computer simulations are created to help find out.

M27: туманность Гантель APOD: 2023 May 30 Б M27: The Dumbbell Nebula

Is this what will become of our Sun? Quite possibly. The first hint of our Sun's future was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets.

Млечный Путь над бирюзовой страной чудес APOD: 2023 May 29 Б Milky Way over a Turquoise Wonderland

What glows there? The answer depends: sea or sky? In the sea, the unusual blue glow is bioluminescence. Specifically, the glimmer arises from Noctiluca scintillans, single-celled plankton stimulated by the lapping waves. The plankton use their glow to startle and illuminate predators.

Ида и Дактиль: астероид и его спутник APOD: 2023 May 28 Б Ida and Dactyl: Asteroid and Moon

This asteroid has a moon. The robot spacecraft Galileo on route to Jupiter in 1993 encountered and photographed two asteroids during its long interplanetary voyage. The second minor planet it photographed, 243 Ida, was unexpectedly discovered to have a moon.

Полумесяцы Нептуна и Тритона Crescent Neptune and Triton

Gliding through the outer Solar System, in 1989 the Voyager 2 spacecraft looked toward the Sun to find this view of most distant planet Neptune and its moon Triton together in a crescent phase. The elegant image of ice-giant planet and largest moon was taken from behind just after Voyager's closest approach.

Галактики из скопления в Деве Virgo Cluster Galaxies

Galaxies of the Virgo Cluster are scattered across this nearly 4 degree wide telescopic field of view. About 50 million light-years distant, the Virgo Cluster is the closest large galaxy cluster to our own local galaxy group.

Кошачий глаз на глубоком широкоугольном изображении Cat s Eye Wide and Deep

The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But this wide and deep image combining data from two telescopes also reveals its extremely faint outer halo.

Обсерватория на фоне покрытия Юпитера Луной APOD: 2023 May 24 Б Observatory Aligned with Moon Occulting Jupiter

Sometimes we witness the Moon moving directly in front of -- called occulting -- one of the planets in our Solar System. Earlier this month that planet was Jupiter. Captured here was the moment when Jupiter re-appeared from behind the surface of our Moon.

Вихри на Юпитере от "Юноны" APOD: 2023 May 23 Б Jupiters Swirls from Juno

Big storms are different on Jupiter. On Earth, huge hurricanes and colossal cyclones are centered on regions of low pressure, but on Jupiter, it is the high-pressure, anti-cyclone storms that are the largest. On Earth, large storms can last weeks, but on Jupiter they can last years.

Сверхновая открыта в близкой спиральной галактике M101 APOD: 2023 May 22 Б Supernova Discovered in Nearby Spiral Galaxy M101

A nearby star has exploded and humanity's telescopes are turning to monitor it. The supernova, dubbed SN 2023ifx, was discovered by Japanese astronomer Koichi Itagaki three days ago and subsequently located on automated images from the Zwicky Transient Facility two days earlier.
