Кольцеобразное солнечное затмение над Нью-Мексико APOD: 2023 September 10 Б An Annular Solar Eclipse over New Mexico

What is this person doing? In 2012, an annular eclipse of the Sun was visible over a narrow path that crossed the northern Pacific Ocean and several western US states. In an annular solar...

Комета Нишимура растет APOD: 2023 September 9 Б Comet Nishimura Grows

Comet Nishimura is growing. More precisely, the tails C/2023 P1 (Nishimura) are growing as it nears the Sun. Discovered only last month, the comet is already near naked eye brightness as it now moves inside the Earth's orbit.

Звездная фабрика Мессье 17 Star Factory Messier 17

Sculpted by stellar winds and radiation, the star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this 1/3 degree wide field of view spans over 30 light-years.

Большое Магелланово Облако The Large Cloud of Magellan

The 16th century Portuguese navigator Ferdinand Magellan and his crew had plenty of time to study the southern sky during the first circumnavigation of planet Earth. As a result, two fuzzy cloud-like objects easily...

Телескопы HESS исследуют небо в высокоэнергичном диапазоне APOD: 2023 September 6 Б HESS Telescopes Explore the High Energy Sky

They may look like modern mechanical dinosaurs, but they are enormous swiveling eyes that watch the sky. The High Energy Stereoscopic System (H.E.S.S.) Observatory is composed of four 12-meter reflecting-mirror telescopes surrounding a larger telescope housing a 28-meter mirror.

Голубая Суперлуна над Сиракузами APOD: 2023 September 5 Б Blue Supermoon Beyond Syracuse

The last full moon was doubly unusual. First of all, it was a blue moon. A modern definition of a blue moon is a second full moon to occur during one calendar month. Since there are 13 full moons in 2023, one month has to have two -- and that month was August.

Лебедь: Пузырь и Полумесяц APOD: 2023 September 4 Б Cygnus: Bubble and Crescent

As stars die, they create clouds. Two stellar death clouds of gas and dust can be found toward the high-flying constellation of the Swan (Cygnus) as they drift through rich star fields in the plane of our Milky Way Galaxy.

Фрагменты кометы Швассмана-Вахмана 3 APOD: 2023 September 3 Б Comet Schwassmann Wachmann 3 Fragments

Periodic comet 73P/Schwassmann-Wachmann 3 has broken up at least twice. A cosmic souffle of ice and dust left over from the early solar system, this comet was first seen to split into several large pieces during the close-in part of its orbit in 1995.

NGC 7023: туманность Ирис NGC 7023: The Iris Nebula

These cosmic clouds have blossomed 1,300 light-years away in the fertile starfields of the constellation Cepheus. Called the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers.

Огромное шаровое скопление в Геркулесе The Great Globular Cluster in Hercules

In 1716, English astronomer Edmond Halley noted, "This is but a little Patch, but it shows itself to the naked Eye, when the Sky is serene and the Moon absent." Of course...
