Astronomy Picture Of the Day (APOD)

Комета, планета, Луна APOD: 2024 April 29 Б Comet, Planet, Moon
28.04.2024

Three bright objects satisfied seasoned stargazers of the western sky just after sunset earlier this month. The most familiar was the Moon, seen on the upper left in a crescent phase. The rest of the Moon was faintly visible by sunlight first reflected by the Earth.


Кольца вокруг туманности Кольцо APOD: 2024 April 28 Б Rings Around the Ring Nebula
27.04.2024

The Ring Nebula (M57) is more complicated than it appears through a small telescope. The easily visible central ring is about one light-year across, but this remarkably deep exposure - a collaborative effort combining data from three different large telescopes - explores the looping filaments of glowing gas extending much farther from the nebula's central star.


Лунная тень на всем небе All Sky Moon Shadow
26.04.2024

If the Sun is up but the sky is dark and the horizon is bright all around, you might be standing in the Moon's shadow during a total eclipse of the Sun. In fact, the all-sky Moon shadow shown in this composited panoramic view was captured from a farm near Shirley, Arkansas, planet Earth.


Регул и карликовая галактика Regulus and the Dwarf Galaxy
25.04.2024

In northern hemisphere spring, bright star Regulus is easy to spot above the eastern horizon. The alpha star of the constellation Leo, Regulus is the spiky star centered in this telescopic field of view.


NGC 604: гигантские звездные ясли NGC 604: Giant Stellar Nursery
24.04.2024

Located some 3 million light-years away in the arms of nearby spiral galaxy M33, giant stellar nursery NGC 604 is about 1,300 light-years across. That's nearly 100 times the size of the Milky Way's Orion Nebula, the closest large star forming region to planet Earth.


Биполярная эмиссионная туманность Яйцо Дракона APOD: 2024 April 24 Б Dragons Egg Bipolar Emission Nebula
23.04.2024

How did a star form this beautiful nebula? In the middle of emission nebula NGC 6164 is an unusually massive star. The central star has been compared to an oyster's pearl and an egg protected by the mythical sky dragons of Ara.


Крест на облаках APOD: 2024 April 23 Б Contrail Shadow X
22.04.2024

What created this giant X in the clouds? It was the shadow of contrails illuminated from below. When airplanes fly, humid engine exhaust may form water droplets that might freeze in Earth's cold upper atmosphere. These persistent streams of water and ice scatter light from the Sun above and so appear bright from below.


Луна и кольца из дыма над горой Этна APOD: 2024 April 22 Б Moon and Smoke Rings from Mt Etna
21.04.2024

Yes, but can your volcano do this? To the surprise of some, Mt. Etna emits, on occasion, smoke rings. Technically known as vortex rings, the walls of the volcano slightly slow the outside of emitted smoke puffs, causing the inside gas to move faster.


Перийовий 16: пролетая над Юпитером APOD: 2024 April 21 Б Perijove 16: Passing Jupiter
20.04.2024

Watch Juno zoom past Jupiter. NASA's robotic spacecraft Juno is continuing on its now month-long, highly-elongated orbits around our Solar System's largest planet. The featured video is from perijove 16, the sixteenth time that Juno passed near Jupiter since it arrived in mid-2016.


Бриллианты на небе Diamonds in the Sky
19.04.2024

When the dark shadow of the Moon raced across North America on April 8, sky watchers along the shadow's narrow central path were treated to a total solar eclipse. During the New Moon's shadow play diamonds glistened twice in the eclipse-darkened skies.
