Geminids of the South

Geminids of the South

Copyright: Fefo Bouvier Fireflies flash along a moonlit countryside in this scene taken on the night of December 13/14 from southern Uruguay, planet Earth. On that night meteors fell in the partly cloudy skies above during the annual Geminid meteor shower. Frames recorded over a period of 1.5 hours are aligned in the composite image […]

Comet Leonard from Space

Comet Leonard from Space

Copyright: Zhuoxiao WangOrigin.Space What does Comet Leonard look like from space? Today’s featured image from Origin.Space’s Yangwang-1 space telescope shows not only the currently bright comet — but several other space delights as well. Taken in optical and ultraviolet light, C/2021 A1 (Leonard) is visible with an extended tail near the image center as it […]

HH 666: Carina Dust Pillar with Jet

HH 666: Carina Dust Pillar with Jet

Copyright: To some, it may look like a beehive. In reality, the featured image from the Hubble Space Telescope captures a cosmic pillar of dust, over two-light years long, inside of which is Herbig-Haro 666 — a young star emitting powerful jets. The structure lies within one of our galaxy’s largest star forming regions, the […]

Meteors and Auroras over Iceland

Meteors and Auroras over Iceland

Copyright: James Boardman-Woodend Annotation: Judy Schmidt What’s going on behind that mountain? Quite a bit. First of all, the mountain itself, named Kirkjufell, is quite old and located in western Iceland near the town of Grundarfjörður. In front of the steeply-sloped structure lies a fjord that had just begun to freeze when the above image […]

Comet Leonard Before Star Cluster M3

Comet Leonard Before Star Cluster M3

Copyright: Dan Bartlett Comet Leonard is now visible to the unaided eye — but just barely. Passing nearest to the Earth today, the comet is best seen this week soon after sunset, toward the west, low on the horizon. Currently best visible in the north, by late December the comet will best be seen from […]

Postcard from the South Pole

Postcard from the South Pole

Copyright: Aman Chokshi 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. Of course, crews at the South Pole Telescope (left) and […]

Eclipse on a Polar Day

Eclipse on a Polar Day

Copyright: Stephanie Ziyi Ye 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. Of course on […]

A Total Eclipse of the Sun

A Total Eclipse of the Sun

Copyright: JM Pasachoff Antarctic Expedition 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. Still, some enthusiastic and well-insulated eclipse chasers were rewarded with […]

Comet Hale-Bopp Over Val Parola Pass

Comet Hale-Bopp Over Val Parola Pass

Copyright: Col Druscie Obs.AAC 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. […]

Ninety Gravitational Wave Spectrograms and Counting

Ninety Gravitational Wave Spectrograms and Counting

Copyright: very 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. Featured above are […]

Space Station Silhouette on the Moon

Space Station Silhouette on the Moon

Copyright: Andrew McCarthy 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. The featured composite, taken from Payson, Arizona, USA last month, was intricately composed by combining, in part, many 1/2000-second images from […]

Total Solar Eclipse Below the Bottom of the World

Total Solar Eclipse Below the Bottom of the World

Copyright: Petr HorálekESOPhoto AmbassadorInst. of Physics in Opava 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 one relatively spectacular capture where the bright spot is the outer corona of […]

Iridescent by Moonlight

Iridescent by Moonlight

Copyright: Marcella Giulia Pace 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 […]

Comet Leonard and the Whale Galaxy

Comet Leonard and the Whale Galaxy

Copyright: Gregg Ruppel 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. Of course NGC 4631 and NGC 4656 […]

NGC 6822: Barnard’s Galaxy

Copyright: Dietmar Hager 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. Beyond the rich starfields in the constellation Sagittarius, NGC 6822 is a mere 1.5 million […]
