Astronomy Picture Of the Day (APOD)

Глубокое поле: Большое Магелланово Облако APOD: 2023 March 7 Б Deep Field: The Large Magellanic Cloud

Is this a spiral galaxy? No. Actually, it is the Large Magellanic Cloud (LMC), the largest satellite galaxy of our own Milky Way Galaxy. The LMC is classified as a dwarf irregular galaxy because of its normally chaotic appearance. In this deep and wide exposure, however, the full extent of the LMC becomes visible.

Юпитер и Венера с Земли APOD: 2023 March 6 Б Jupiter and Venus from Earth

It was visible around the world. The sunset conjunction of Jupiter and Venus in 2012 was visible almost no matter where you lived on Earth. Anyone on the planet with a clear western horizon at sunset could see them.

Юпитер и Венера над Италией APOD: 2023 March 5 Б Jupiter and Venus over Italy

What are those two bright spots? Planets. A few days ago, the two brightest planets in the night sky passed within a single degree of each other in what is termed a conjunction. Visible just after sunset in much of the world, the two bright spots were Jupiter (left) and Venus (right).

10 дней Венеры и Юпитера 10 Days of Venus and Jupiter

Venus and Jupiter may have caught your attention lately. The impending close conjunction of the two brightest planets visible in clear evening skies has been hard to miss. With Jupiter at the top, starting...

RCW 86: остаток исторической сверхновой RCW 86: Historical Supernova Remnant

In 185 AD, Chinese astronomers recorded the appearance of a new star in the Nanmen asterism. That part of the sky is identified with Alpha and Beta Centauri on modern star charts. The new star was visible to the naked-eye for months, and is now thought to be the earliest recorded supernova.

Распутывающаяся галактика NGC 3169 Unraveling NGC 3169

Spiral galaxy NGC 3169 looks to be unraveling like a ball of cosmic yarn. It lies some 70 million light-years away, south of bright star Regulus toward the faint constellation Sextans. Wound up spiral arms are pulled out into sweeping tidal tails as NGC 3169 (left) and neighboring NGC 3166 interact gravitationally.

Туманность Пылающей звезды APOD: 2023 March 1 Б The Flaming Star Nebula

Is star AE Aurigae on fire? No. Even though AE Aurigae is named the Flaming Star and the surrounding nebula IC 405 is named the Flaming Star Nebula, and even though the nebula appears to some like a swirling flame, there is no fire.

Полумесяц за греческим храмом APOD: 2023 February 28 Б Crescent Moon Beyond Greek Temple

Why is a thin crescent moon never seen far from a horizon? Because the only geometry that gives a thin crescent lunar phase occurs when the Moon appears close to the Sun in the sky.

Зодиакальный свет с Венерой и Юпитером APOD: 2023 February 27 Б Zodiacal Ray with Venus and Jupiter

What's causing that unusual ray of light extending from the horizon? Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently after sunset or before sunrise and is called zodiacal light.

Япет: спутник Сатурна со странной поверхностью APOD: 2023 February 26 Б Saturns Iapetus: Moon with a Strange Surface

What would make a moon look like a walnut? A strange ridge that circles Saturn's moon Iapetus's equator, visible near the bottom of the featured image, makes it appear similar to a popular edible nut.
