Astronomy Picture Of the Day (APOD)

Частное лунное затмение APOD: 2023 October 29 Б A Partial Lunar Eclipse
29.10.2023

What's happened to the Moon? Within the last day, part of the Moon moved through the Earth's shadow. This happens about once or twice a year, but not every month since the Moon's orbit around the Earth is slightly tilted.


Призраки γ Кассиопеи The Ghosts of Gamma Cas
28.10.2023

Gamma Cassiopeiae shines high in northern autumn evening skies. It's the brightest spiky star in this telescopic field of view toward the constellation Cassiopeia. Gamma Cas shares the ethereal-looking scene with ghostly interstellar clouds of gas and dust, IC 59 (top left) and IC 63.


Комета Энке и Головастики Encke and the Tadpoles
27.10.2023

History's second known periodic comet is Comet Encke (2P/Encke). As it swings through the inner Solar System, Encke's orbit takes it from an aphelion, its greatest distance from the Sun, inside the orbit of Jupiter to a perihelion just inside the orbit of Mercury.


Ориониды в Тельце Orionids in Taurus
26.10.2023

History's first known periodic comet, Comet Halley (1P/Halley), returns to the inner Solar System every 76 years or so. The famous comet made its last appearance to the naked-eye in 1986. But dusty...


Исчезло за 60 секунд: закат и зеленый луч APOD: 2023 October 25 Б Gone in 60 Seconds: A Green Flash Sunset
25.10.2023

In 60 seconds, this setting Sun will turn green. Actually, the top of the Sun already appears not only green, but wavey -- along with all of its edges. The Sun itself is unchanged -- both effects are caused by looking along hot and cold layers in Earth's atmosphere.


Арп 87: сливающиеся галактики APOD: 2023 October 24 Б Arp 87: Merging Galaxies from Hubble
24.10.2023

This dance is to the death. As these two large galaxies duel, a cosmic bridge of stars, gas, and dust currently stretches over 75,000 light-years and joins them. The bridge itself is strong evidence that these two immense star systems have passed close to each other and experienced violent tides induced by mutual gravity.


Спутник Ио от космического аппарата "Юнона" APOD: 2023 October 23 Б Moon Io from Spacecraft Juno
23.10.2023

There goes another one! Volcanoes on Jupiter's moon Io keep erupting. To investigate, NASA's robotic Juno spacecraft has begun a series of visits to this very strange moon. Io is about...


Северное сияние – привидение над Канадой APOD: 2023 October 22 Б Ghost Aurora over Canada
22.10.2023

What does this aurora look like to you? While braving the cold to watch the skies above northern Canada early one morning in 2013, a most unusual aurora appeared. The aurora definitely appeared to be shaped like something, but what?


Четверти Луны Quarter Moons
21.10.2023

Half way between New Moon and Full Moon is the Moon's first quarter phase. That's a quarter of the way around its moonthly orbit. At the first quarter phase, half the Moon's visible side is illuminated by sunlight.


Галактики и комета Galaxies and a Comet
20.10.2023

Galaxies abound in this sharp telescopic image recorded on October 12 in dark skies over June Lake, California. The celestial scene spans nearly 2 degrees within the boundaries of the well-trained northern constellation Canes Venatici.
