Astronomy Picture Of the Day (APOD)

Оболочки и дуги вокруг звезды CW Льва APOD: 2023 July 17 Б Shells and Arcs around Star CW Leonis

What's happening around this star? No one is sure. CW Leonis is the closest carbon star, a star that appears orange because of atmospheric carbon dispersed from interior nuclear fusion. But CW Leonis also appears engulfed in a gaseous carbon-rich nebula.

Метеор и Млечный Путь над Альпами APOD: 2023 July 16 Б Meteor and Milky Way over the Alps

Now this was a view with a thrill. From Mount Tschirgant in the Alps, you can see not only nearby towns and distant Tyrolean peaks, but also, weather permitting, stars, nebulas, and the band of the Milky Way Galaxy.

Первое глубокое поле телескопа "Джеймс Вебб" Webb's First Deep Field

This stunning infrared image was released one year ago as the James Webb Space Telescope began its exploration of the cosmos. The view of the early Universe toward the southern constellation Volans was achieved in 12.5 hours of exposure with Webb's NIRCam instrument.

Комета C 2023 E1 ATLAS около перигелия Comet C 2023 E1 ATLAS near Perihelion

Comet C/2023 E1 (ATLAS) was just spotted in March, another comet found by the NASA funded Asteroid Terrestrial-impact Last Alert System. On July 1 this Comet ATLAS reached perihelion, its closest approach to the Sun.

ρ Змееносца от телескопа "Джеймс Вебб" Webb s Rho Ophiuchi

A mere 390 light-years away, Sun-like stars and future planetary systems are forming in the Rho Ophiuchi molecular cloud complex, the closest star-forming region to our fair planet. The James Webb Space Telescope's NIRCam peered into the nearby natal chaos to capture this infrared image at an inspiring scale.

Кольца и перемычка в спиральной галактике NGC 1398 APOD: 2023 July 12 Б Rings and Bar of Spiral Galaxy NGC 1398

Why do some spiral galaxies have a ring around the center? Spiral galaxy NGC 1398 not only has a ring of pearly stars, gas and dust around its center, but a bar of stars and gas across its center, and spiral arms that appear like ribbons farther out.

Пятна на активном Солнце APOD: 2023 July 11 Б Sunspots on an Active Sun

Why is our Sun so active now? No one is sure. An increase in surface activity was expected because our Sun is approaching solar maximum in 2025. However, last month our Sun sprouted more sunspots than in any month during the entire previous 11-year solar cycle -- and even dating back to 2002.

Звезды, пыль и туманность в NGC 6559 APOD: 2023 July 10 Б Stars, Dust and Nebula in NGC 6559

When stars form, pandemonium reigns. A textbook case is the star forming region NGC 6559. Visible in the featured image are red glowing emission nebulas of hydrogen, blue reflection nebulas of dust, dark absorption nebulas of dust, and the stars that formed from them.

Обреченная звезда η Киля APOD: 2023 July 9 Б Doomed Star Eta Carinae

Eta Carinae may be about to explode. But no one knows when - it may be next year, it may be one million years from now. Eta Carinae's mass - about 100 times greater than our Sun - makes it an excellent candidate for a full blown supernova.

Кратер Стикни Stickney Crater

Stickney Crater, the largest crater on the martian moon Phobos, is named for Chloe Angeline Stickney Hall, mathematician and wife of astronomer Asaph Hall. Asaph Hall discovered both the Red Planet's moons in 1877.
