Astronomy Picture Of the Day (APOD)

Красное северное сияние над Италией APOD: 2023 November 6 Б Red Aurora over Italy

What was that red glow on the horizon last night? Aurora. Our unusually active Sun produced a surface explosion a few days ago that sent out a burst of electrons, protons, and more massive charged nuclei.

Северное сияние над Норвегией в виде сказочного существа APOD: 2023 November 5 Б Creature Aurora Over Norway

It was Halloween and the sky looked like a creature. Exactly which creature, the astrophotographer was unsure (but possibly you can suggest one). Exactly what caused this eerie apparition in 2013 was sure: one of the best auroral displays that year. This spectacular aurora had an unusually high degree of detail.

Восход спутника Динкинеша Dinkinesh Moonrise

Last Wednesday the voyaging Lucy spacecraft encountered its first asteroid, 152830 Dinkinesh, and discovered the inner-main belt asteroid has a moon. From a distance of just over 400 kilometers, Lucy's Long-Range Reconnaissance Imager...

Юпитер в лунном свете Jupiter by Moonlight

That bright beacon you've seen rising in the east just after sunset is Jupiter. Climbing high in midnight skies, our Solar System's ruling gas giant was at its 2023 opposition, opposite the Sun in planet Earth's sky, on November 2.

Скопление галактик в Печи The Fornax Cluster of Galaxies

Named for the southern constellation toward which most of its galaxies can be found, the Fornax Cluster is one of the closest clusters of galaxies. About 62 million light-years away, it's over...

Кольцеобразное солнечное затмение над Ютой APOD: 2023 November 1 Б Annular Solar Eclipse over Utah

Part of the Sun disappeared earlier this month, but few people were worried. The missing part, which included the center from some locations, just went behind the Moon in what is known as an annular solar eclipse. Featured here is an eclipse sequence taken as the Moon was overtaking the rising Sun in the sky.

Хэллоуин и туманность Колдун APOD: 2023 October 31 Б Halloween and the Wizard Nebula

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).

Отражения туманности Призрак APOD: 2023 October 30 Б Reflections of the Ghost Nebula

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.

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

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

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.
