Astronomy Picture Of the Day (APOD)

Остаток сверхновой Кассиопея А Supernova Remnant Cassiopeia A

Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After only a few million years for the most massive stars, the enriched material is blasted back into interstellar space where star formation can begin anew.

Глубокое поле: туманность Сердце APOD: 2023 December 13 Б Deep Field: The Heart Nebula

What excites the Heart Nebula? First, the large emission nebula on the left, catalogued as IC 1805, looks somewhat like a human heart. The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by silicon (yellow) and oxygen (blue).

Северное сияние и Млечный Путь над Норвегией APOD: 2023 December 12 Б Aurora and Milky Way over Norway

What are these two giant arches across the sky? Perhaps the more familiar one, on the left, is the central band of our Milky Way Galaxy. This grand disk of stars and nebulas here appears to encircle much of the southern sky.

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...
