APOD: 2025 August 3 B Milky Way and Exploding Meteor
3.08.2025 | Astronomicheskaya kartinka dnya

In about a week the Perseid Meteor Shower will reach its maximum. Grains of icy rock will streak across the sky as they evaporate during entry into Earth's atmosphere. These grains were shed from Comet Swift-Tuttle.

Taken on July 29 and July 30, a registered and stacked series of exposures creates this dreamlike view of a northern summer night. Multiple firefly flashes streak across the foreground as the luminous Milky...

APOD: 2025 August 1 B Small Dark Nebula
1.08.2025 | Astronomicheskaya kartinka dnya

A small, dark, nebula looks isolated near the center of this telescopic close-up. The wedge-shaped cosmic cloudlet lies within a relatively crowded region of space though. About 7,000 light-years distant and filled with glowing gas and an embedded cluster of young stars, the region is known as M16 or the Eagle Nebula.

Ochen' davno v galaktike, udalennoi ot nas na 50 millionov svetovyh let, vzorvalas' zvezda. Svet ot etoi sverhnovoi byl vpervye zaregistrirovan teleskopami na planete Zemlya 14 iyulya, seichas etot vnegalakticheskii tranzient izvesten astronomam kak sverhnovaya 2025rbs. V nastoyashee vremya eto yarchaishaya sverhnovaya na nebe planety Zemlya.

APOD: 2025 July 30 B Coronal Loops on the Sun
30.07.2025 | Astronomicheskaya kartinka dnya

Our Sun frequently erupts in loops. Hot solar plasma jumps off the Sun's surface into prominences, with the most common type of prominence being a simple loop. The loop shape originates from the Sun's magnetic field, which is traced by spiraling electrons and protons.

Is the Helix Nebula looking at you? No, not in any biological sense, but it does look quite like an eye. The Helix Nebula is so named because it also appears that you are looking down the axis of a helix.

APOD: 2025 July 27 B Lightning over the Volcano of Water
27.07.2025 | Astronomicheskaya kartinka dnya

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.

Sharovoe skoplenie ω Centavra
26.07.2025 | Astronomicheskaya kartinka dnya

Sharovoe zvezdnoe skoplenie ω Centavra, takzhe izvestnoe kak NGC 5139, udaleno ot nas na 15 tysyach svetovyh let. V etom skoplenii v oblasti s diametrom okolo 150 svetovyh let nahoditsya primerno 10 millionov zvezd, kazhdaya iz kotoryh gorazdo starshe Solnca.

APOD: 2025 July 25 B Twelve Years of Kappa Cygnids
25.07.2025 | Astronomicheskaya kartinka dnya

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 B Titan Shadow Transit
24.07.2025 | Astronomicheskaya kartinka dnya

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.
