Открытка с южного полюса Postcard from the South Pole

From this vantage point about three quarters of a mile from planet Earth's geographic South Pole, the December 4 eclipse of the Sun was seen as a partial eclipse. At maximum eclipse the New Moon blocked 90 percent of the solar disk.

Затмение в полярный день Eclipse on a Polar Day

During polar day, in Arctic and Antarctic summer, the Sun stays above the horizon for periods of 24 hours or more. Recorded on December 4, this fisheye timelapse image tracks the Sun in multiple frames as it completes a circle in the summer sky above Union Glacier, Antarctica.

Полное затмение Солнца A Total Eclipse of the Sun

Few were able to stand in the Moon's shadow and watch the December 4 total eclipse of the Sun. Determined by celestial mechanics and not geographical boundaries, the narrow path of totality tracked across planet Earth's relatively inaccessible southernmost continent.

Комета Хейла-Боппа над перевалом Вал Парола Comet Hale Bopp Over Val Parola Pass

Comet Hale-Bopp, the Great Comet of 1997, became much brighter than any surrounding stars. It was seen even over bright city lights. Away from city lights, however, it put on quite a spectacular show. Here Comet Hale-Bopp was photographed above Val Parola Pass in the Dolomite mountains surrounding Cortina d'Ampezzo, Italy.

Девяносто спектрограмм гравитационных волн Ninety Gravitational Wave Spectrograms and Counting

Every time two massive black holes collide, a loud chirping sound is broadcast out into the universe in gravitational waves. Humanity has only had the technology to hear these unusual chirps for the past seven years, but since then we have heard about 90 -- during the first three observing runs.

Силуэт космической станции на фоне Луны Space Station Silhouette on the Moon

What's that unusual spot on the Moon? It's the International Space Station. Using precise timing, the Earth-orbiting space platform was photographed in front of a partially lit gibbous Moon last month.

Полное солнечное затмение на краю мира Total Solar Eclipse Below the Bottom of the World

Yesterday there was a total solar eclipse visible only at the end of the Earth. To capture the unusual phenomenon, airplanes took flight below the clouded seascape of Southern Ocean. The featured image shows...

Радужное облако в лунном свете Iridescent by Moonlight

In this snapshot from November 18, the Full Moon was not far from Earth's shadow. In skies over Sicily the brightest lunar phase was eclipsed by passing clouds though. The full moonlight was dimmed and momentarily diffracted by small but similar sized water droplets near the edges of the high thin clouds.

Комета Леонарда и галактика Кит Comet Leonard and the Whale Galaxy

Sweeping through northern predawn skies, on November 24 Comet Leonard (C/2021 A1) was caught between two galaxies in this composite telescopic image. Sporting a greenish coma the comet's dusty tail seems to harpoon the heart of NGC 4631 (top) also known as the Whale Galaxy.

NGC 6822: галактика Барнарда NGC 6822: Barnard s Galaxy

Grand spiral galaxies often seem to get all the glory, flaunting their young, bright, blue star clusters in beautiful, symmetric spiral arms. But small galaxies form stars too, like nearby NGC 6822, also known as Barnard's Galaxy.
