Astronomy Picture Of the Day (APOD)

Разноцветные облака и звезды около ρ Змееносца APOD: 2024 June 11 Б Colorful Stars and Clouds near Rho Ophiuchi
10.06.2024

Why is the sky near Antares and Rho Ophiuchi so colorful, yet dusty? The colors result from a mixture of objects and processes. Fine dust -- illuminated by starlight -- produces blue reflection nebulae. Gaseous clouds whose atoms are excited by ultraviolet starlight produce reddish emission nebulae. Backlit dust clouds block starlight and so appear dark.


Sh2-132: туманность Лев APOD: 2024 June 10 Б Sh2 132: The Lion Nebula
9.06.2024

Is the Lion Nebula the real ruler of the constellation Cepheus? This powerful feline appearing nebula is powered by two massive stars, each with a mass over 20 times greater than our Sun. Formed...


Как определить, что светится на небе APOD: 2024 June 9 Б How to Identify that Light in the Sky
8.06.2024

What is that light in the sky? The answer to one of humanity's more common questions may emerge from a few quick observations. For example -- is it moving or blinking?


Скопление галактик Пандора Pandora's Cluster of Galaxies
7.06.2024

This deep field mosaicked image presents a stunning view of galaxy cluster Abell 2744 recorded by the James Webb Space Telescope's NIRCam. Also dubbed Pandora's Cluster, Abell 2744 itself appears to be a ponderous merger of three different massive galaxy clusters. It lies some 3.5 billion light-years away, toward the constellation Sculptor.


Шарплесс 308: туманность Голова Дельфина Sharpless 308: The Dolphin Head Nebula
6.06.2024

Blown by fast winds from a hot, massive star, this cosmic bubble is huge. Cataloged as Sharpless 2-308 it lies some 5,000 light-years away toward the well-trained constellation Canis Major and covers slightly more of the sky than a Full Moon. That corresponds to a diameter of 60 light-years at its estimated distance.


NGC 4565: галактика, видимая с ребра NGC 4565: Galaxy on Edge
5.06.2024

Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices.


Тень марсианского робота APOD: 2024 June 5 Б Shadow of a Martian Robot
4.06.2024

What if you saw your shadow on Mars and it wasn't human? Then you might be the Perseverance rover exploring Mars. Perseverance has been examining the Red Planet since 2021, finding evidence of its complex history of volcanism and ancient flowing water, and sending breathtaking images across the inner Solar System.


У кометы Понса-Брукса появился противоположно направленный хвост APOD: 2024 June 4 Б Comet Pons Brooks Develops Opposing Tails
3.06.2024

Why does Comet Pons-Brooks now have tails pointing in opposite directions? The most spectacular tail is the blue-glowing ion tail that is visible flowing down the image. The ion tail is pushed directly out from the Sun by the solar wind. On the upper right is the glowing central coma of Comet 12P/PonsБBrooks.


NGC 2403 в Жирафе NGC 2403 in Camelopardalis
2.06.2024

Magnificent island universe NGC 2403 stands within the boundaries of the long-necked constellation Camelopardalis. Some 10 million light-years distant and about 50,000 light-years across, the spiral galaxy also seems to have more than its fair share of giant star forming HII regions, marked by the telltale reddish glow of atomic hydrogen gas.


Вращающаяся Луна от "Лунного орбитального разведчика" APOD: 2024 June 2 Б Rotating Moon from LRO
1.06.2024

No one, presently, sees the Moon rotate like this. That's because the Earth's moon is tidally locked to the Earth, showing us only one side. Given modern digital technology, however, combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie has been composed.
