Astronomy Picture Of the Day (APOD)

Солнечный минимум против солнечного максимума APOD: 2023 December 11 Б Solar Minimum versus Solar Maximum

The surface of our Sun is constantly changing. Some years it is quiet, showing relatively few sunspots and active regions. Other years it is churning, showing many sunspots and throwing frequent Coronal Mass Ejections (CMEs) and flares.

Большой Ковш над горой Пирамида APOD: 2023 December 10 Б Big Dipper over Pyramid Mountain

When did you first learn to identify this group of stars? Although they are familiar to many people around the world, different cultures have associated this asterism with different icons and folklore. Known...

Пик Плеяд Pic du Pleiades

Near dawn on November 19 the Pleiades stood in still dark skies over the French Pyrenees. But just before sunrise a serendipitous moment was captured in this single 3 second exposure; a bright meteor streak appeared to pierce the heart of the galactic star cluster.

Вега и комета 12P Понса-Брукса Vega and Comet 12P Pons-Brooks

On December 4, periodic Comet 12P/Pons-Brooks shared this telescopic field of view with Vega, alpha star of the northern constellation Lyra. Fifth brightest star in planet Earth's night, Vega is some 25 light-years distant while the much fainter comet was about 21 light-minutes away.

"Орион" и океан Бурь Orion and the Ocean of Storms

On December 5, 2022, a camera on board the uncrewed Orion spacecraft captured this view as Orion approached its return powered flyby of the Moon. Beyond one of Orion's extended solar arrays lies dark, smooth, terrain along the western edge of the Oceanus Procellarum.

Звезды против пыли в туманности Киля APOD: 2023 December 6 Б Stars Verus Dust in the Carina Nebula

It's stars versus dust in the Carina Nebula and the stars are winning. More precisely, the energetic light and winds from massive newly formed stars are evaporating and dispersing the dusty stellar nurseries in which they formed.

Частица с высокой энергией сталкивается с Землей APOD: 2023 December 5 Б Energetic Particle Strikes the Earth

It was one of the most energetic particles ever known to strike the Earth -- but where did it come from? Dubbed Amaterasu after the Shinto sun goddess, this particle, as do all cosmic rays...

Самолет пролетает перед полумесяцем APOD: 2023 December 4 Б Plane Crossing Crescent Moon

No, the Moon is not a bow, and no, it did not shoot out a plane like an arrow. What is pictured is a chance superposition. The plane's contrail would normally appear white...

Заход Луны за вулканом Тейде APOD: 2023 December 3 Б Moon Setting Behind Teide Volcano

These people are not in danger. What is coming down from the left is just the Moon, far in the distance. Luna appears so large here because she is being photographed through a telescopic lens.

Следы звезд над древней Пекинской обсерваторией Startrails over Beijing Ancient Observatory

You can take a subway ride to visit this observatory in Beijing, China but you won't find any telescopes there. Starting in the 1400s astronomers erected devices at the Beijing Ancient Observatory site to enable them to accurately measure and track the positions of naked-eye stars and planets.
