The Man to Send Rain Clouds Theme of Continuity and Change
These are the best astronomy images of the year
The best astronomy photos of the year invite the eye upward and outward, bringing stunning views such as auroras above Earth and visions of a stellar nursery 554 light-years away.
These images, from the finalists in the 13th annual Royal Observatory Greenwich's Astronomy Photographer of the Year competition, are a beautiful reminder of the size and age of the universe. One image, created by photographer James Rushforth, shows the comet NEOWISE passing over Stonehenge, a structure that didn't even exist when the comet last streaked by Earth 6,800 years ago.
Held in cooperation with BBC Sky at Night magazine, the competition drew more than 4,500 entries from 75 different countries. Winners in 12 categories will be announced on September 16, 2021, and the winning photographs will be exhibited in the National Maritime Museum in London. Here are the shortlisted competitors.
A Daytime Transit
(opens in new tab)
The International Space Station travels across a waning crescent moon in this daylight shot. Photographer Andrew McCarthy of Elk Grove, California, used two cameras and two telescopes to capture the images, which he then blended together into a seamless scene.
(For the monochrome image: McCarthy used a Celestron EdgeHD800 telescope at f/10, Hobym Traveller mount, ZWO ASI174MM camera (opens in new tab), 1,000 x 1-millisecond exposure. And for the color, he chose the Orion XT10 telescope at f/10, Hobym Traveller mount, Sony A7II camera, ISO 200, 1-millisecond exposure.)
Aurora in Murmansk
(opens in new tab)
The aurora borealis outshines the lights of Murmansk, Russia, in this photograph taken in January 2020. Photographer Vitaliy Novikov had to wait for a strong solar flare so that the aurora was visible despite the city lights.
(To capture the skylights, Novikov used a Nikon D850 camera (opens in new tab), 24 mm f/5.6 lens, ISO 1000, 0.8-second exposure.)
Bicolor Veil Nebula
(opens in new tab)
This image was stitched together from shots taken of the Veil Nebula in June, July and August 2020. The nebula is the remnant of a giant supernova explosion — the death throes of a massive star. The image was snapped from Pest County, Hungary.
(The photographer used a SkyWatcher 200/800 Newton Astrograph telescope at f/4.6, Astronomik Ha and OIII filters, SkyWatcher NEQ6 Pro mount, Moravian G3-16200 Mark II camera, Ha-OIII composite, 12 hours total exposure.)
Château de Chambord
(opens in new tab)
This chateau in Centre-Val de Loire, France, was a photographer's dream and a challenge for Benjamin Barakat of the U.K., who had to snap photographs during minute-long pauses in the castle's lighting, which occurred once every 15 minutes.
(Baraket used the following equipment: Sigma Art 40 mm telescope, iOptron SkyTracker Pro mount, Canon 6D Baader modified camera. For the foreground, Baraket used a 40 mm f/2.8 lens, ISO 3200, 4 x 30-second exposures; and for the sky, he used a 40 mm f/2 lens, ISO 1600, 8 x 30-second exposures.)
Comet Neowise over Stonehenge
(opens in new tab)
Stonehenge didn't exist 6,800 years ago, the last time the comet NEOWISE passed by Earth. This stunning shot, captured by James Rushforth of the U.K., hints at the incredible changes our planet has seen since the astronomical phenomenon last occurred. An orange glow emanates from the villages of Durrington and Larkhill, and a passing truck's lights illuminate the stones.
(Equipment: Nikon D850 camera (opens in new tab), 70–200 mm lens at 100 mm f/2.8, ISO 5000, 4-second exposure)
Dolphin Head Nebula
(opens in new tab)
The Dolphin Head Nebula sits in the middle of the constellation Canis Major. Yovin Yahathugoda, of Sri Lanka, captured this shot with the help of the Telescope Live remote telescope in Chile. The gorgeous result represents 90 minutes of exposure time spread over three nights of uncooperative weather.
(Yahathugoda used the ASA 500N telescope at f/3.8, Astrodon filters, ASA DDM85 Premium mount, FLI PL16803 camera, Ha-OIII composite, 1.5 hours total exposure.)
Dugi Otok - Variant A
(opens in new tab)
Star trails reveal the rotation of Earth in this shot taken over Dugi Otok in Croatia. The stars reflected in the water were added in post-production because winds over the water prevented the photographer, Ivan Vucetic, from capturing the real-life reflection of the stars.
(Vucetic used a Nikon D600 camera (opens in new tab), 20 mm f/2.8 lens, ISO 1600. The foreground required a 526-second exposure, and the sky 247 x 25-seconds.)
Glory of Damavand and Milky Way
(opens in new tab)
The Milky Way shines over Mount Damavand, Iran, in this shot from May 2020. To capture this image, Masoud Ghadiri took a seven-hour hike to get into position. The photo contains 10 stacked images, five for the sky and five for the foreground.
(Ghadiri used Nikon D850 camera (opens in new tab), Vixen Polarie mount, 24 mm f/4 lens, ISO 6400, 10 x 30-second exposures.)
Harmony
(opens in new tab)
This view of the Milky Way contrasts the stars of the galaxy with the lavender fields of Valensole, France. The photographer, Stefan Liebermann, shot the foreground and night sky separately because the lavender blowing in the breeze would otherwise look like a blur in the long exposures required to capture the Milky Way's beauty.
(Liebermann captured the shot with a Sony ILCE-7M3 camera (opens in new tab), Fornax Mounts LighTrack II mount, 16 mm f/2.8 lens. For the foreground: ISO 2500, 15 x 0.8-second exposures; and for the sky: ISO 2000, 5 x 120-second exposures.)
Iceland Vortex
(opens in new tab)
The aurora lights up the sky near Vik, Iceland, in this shot taken in January 2020. The photographer, Larryn Rae, noted that capturing the northern lights over the powerful natural environment of Iceland in winter was an amazing experience.
(Rae used a Canon EOS 5D Mark 4 (opens in new tab) camera, 16 mm f/2.8 lens, ISO 6400, 20 x 6-second exposures.)
Luna Park
(opens in new tab)
The entrance of Luna Park, an abandoned amusement park in Sydney, Australia, is dark for just a few hours each night. That fleeting period of darkness allowed photographer Ed Hurst to capture this image of stars against the defunct human creation.
(Park used a Pentax 645Z camera (opens in new tab), 25 mm f/4 DA lens. For the foreground: ISO 100, 60-second exposure at f/13; for the sky: ISO 1250, 3,004 x 1.6 second exposures at f/5.)
Martian Sunset
(opens in new tab)
The sun sets on Mars in this shot made from images taken by the Curiosity Rover in 2015. The sun looks slightly smaller than it does on Earth, given Mars' greater distance from our nearest star. The photo is credited to John White.
Milky Way rising over Durdle Door
(opens in new tab)
Durdle Door, a coastal rock formation in Dorset, England, foregrounds the Milky Way in this shot taken in May 2020 by Anthony Sullivan. Saturn and Jupiter are visible above the horizon on the left side of the frame.
(Sullivan captured the images with a Canon 6D camera (opens in new tab). For the foreground: 20 mm f/8 lens, ISO 100, 244-second exposure. And for the sky: 20 mm f/4 lens, ISO 1600, 4 x 240-second exposures.)
Moonrise over Jodrell Bank
(opens in new tab)
The setting sun lights up the clouds as the moon appears over the Lovell Telescope in northwest England. Matt Naylor snapped the image from Holmes Chapel on Dec. 29, 2020.
(Naylor used a Canon EOS 90D camera (opens in new tab), Canon EF 100–400 mm lens at 286 mm f/14, ISO 100, 1/15-second exposure.)
