Astronomy Picture Of the Day (APOD)

APOD: 2025 July 27 Б Lightning over the Volcano of Water APOD: 2025 July 27 Б Lightning over the Volcano of Water
27.07.2025

Have you ever watched a lightning storm in awe? You're not alone. Details of what causes lightning are still being researched, but it is known that inside some clouds, internal updrafts cause collisions between ice and snow that slowly separate charges between cloud tops and bottoms.


Шаровое скопление ω Центавра APOD: 2025 July 26 Б Globular Cluster Omega Centauri
26.07.2025

Globular star cluster Omega Centauri packs about 10 million stars much older than the Sun into a volume some 150 light-years in diameter. Also known as NGC 5139, at a distance...


APOD: 2025 July 25 Б Twelve Years of Kappa Cygnids APOD: 2025 July 25 Б Twelve Years of Kappa Cygnids
25.07.2025

Meteors from the Kappa Cygnid meteor shower are captured in this time-lapse composite skyscape. The minor meteor shower, with a radiant not far from its eponymous star Kappa Cygni, peaks in mid-August, almost at the same time as the much better-known and better-observed Perseid meteor shower.


APOD: 2025 July 24 Б Titan Shadow Transit APOD: 2025 July 24 Б Titan Shadow Transit
24.07.2025

Every 15 years or so, Saturn's rings are tilted edge-on to our line of sight. As the bright, beautiful ring system grows narrower and fainter it becomes increasingly difficult to see for denizens of planet Earth.


APOD: 2025 July 23 Б Fireball over Cape San Blas APOD: 2025 July 23 Б Fireball over Cape San Blas
23.07.2025

Have you ever seen a fireball? In astronomy, a fireball is a very bright meteor -- one at least as bright as Venus and possibly brighter than even a full Moon. Fireballs are rare -- if you see one you are likely to remember it for your whole life.


Сверхновая с двойной детонацией APOD: 2025 July 22 Б A Double Detonation Supernova
22.07.2025

Can some supernovas explode twice? Yes, when the first explosion acts like a detonator for the second. This is a leading hypothesis for the cause of supernova remnant (SNR) 0509-67


Туманность Кошачья Лапа от телескопа "Джеймс Вебб" APOD: 2025 July 21 Б Cats Paw Nebula from Webb Space Telescope
21.07.2025

Nebulas are perhaps as famous for being identified with familiar shapes as perhaps cats are for getting into trouble. Still, no known cat could have created the vast Cat's Paw Nebula visible toward the constellation of the Scorpion (Scorpius).


Видимая сторона Луны APOD: 2025 July 20 Б Lunar Nearside
20.07.2025

About 1,300 images from the Lunar Reconnaissance Orbiter spacecraft's wide angle camera were used to compose this spectacular view of a familiar face - the lunar nearside. But why is there a lunar nearside? The Moon rotates on its axis and orbits the Earth at the same rate, about once every 28 days.


Мессье 6 APOD: 2025 July 19 Б Messier 6
19.07.2025

The sixth object in Charles Messier's famous catalog of things which are not comets, Messier 6 is a galactic or open star cluster. A gathering of 100 stars or so, all around 100 million years young, M6 lies some 1,600 light-years away toward the central Milky Way in the constellation Scorpius.


МКС встречается с Сатурном APOD: 2025 July 18 Б ISS Meets Saturn
18.07.2025

This month, bright planet Saturn rises in evening skies, its rings oriented nearly edge-on when viewed from planet Earth. And in the early morning hours on July 6, it posed very briefly with the International Space Station when viewed from a location in Federal Way, Washington, USA.
