APOD: 2025 July 31 B Supernova 2025rbs in NGC 7331
31.07.2025 | Astronomicheskaya kartinka dnya

A long time ago in a galaxy 50 million light-years away, a star exploded. Light from that supernova was first detected by telescopes on planet Earth on July 14th though, and the extragalactic transient is now known to astronomers as supernova 2025rbs.

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.

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 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.

APOD: 2025 July 23 B Fireball over Cape San Blas
23.07.2025 | Astronomicheskaya kartinka dnya

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.

Mogut li nekotorye sverhnovye vzryvat'sya dva raza? Da, esli pervyi vzryv sluzhit detonatorom dlya vtorogo. Eto samaya veroyatnaya gipoteza proishozhdeniya ostatka sverhnovoi SNR 0509-67
