From remarkable ‘red lightning sprite' to once-in-a-lifetime comet – 7 breathtaking snaps captured by Nasa astronauts
FROM roiling storms, rare comets and volcanic eruptions, there is lots to see aboard the International Space Station (ISS). Fortunately, astronauts are not only equipped with suites of scientific instruments, but cameras too - so we at home can enjoy the view as well.

'Just. Wow. As we went over Mexico and the US this morning, I caught this sprite," Ayers wrote on X earlier this month. "Sprites are TLEs or Transient Luminous Events, that happen above the clouds and are triggered by intense electrical activity in the thunderstorms below. "We have a great view above the clouds, so scientists can use these types of pictures to better understand the formation, characteristics, and relationship of TLEs to thunderstorms."

"It takes planning, timing, and a lot of pictures to capture such a rare phenomenon," she added. 7 Comet C/2023 A3 Tsuchinshan-ATLAS Credit: Don Pettit/NASA 7 The icy comet seen alongside aurora Credit: SWNS Advertisement Once-in-a-lifetime comet Comet C/2023 A3 Tsuchinshan-ATLAS - dubbed the 'once-in-a-lifetime comet' - was photographed by Nasa astronaut Don Pettit from the ISS last autumn. Scientists at the Royal Astronomical Society dubbed it the "comet of the century" because of its brightness and rarity. Most read in Science The icy comet won't be visible on Earth again for another 80,000 years - making the sighting particularly rare. 7 These are two of Earth's most colorful upper atmospheric phenomena Credit: Nasa Advertisement Aurora meets airglow Nasa astronaut Scott Kelly and European Space Agency (ESA) astronaut Tim Peake shared this snap or aurora - or Northern Lights - dancing near Earth's airglow in 2016. In his whopping 340 days in space, Kelly was able to provide some stunning images of Earth seen from above. These are two of Earth's most colorful upper atmospheric phenomena. The wavy green, red-topped wisps of aurora borealis appear to intersect the faint red-yellow band of airglow. Advertisement Though they appear at similar altitudes, aurora and airglow are different. Nighttime airglow - also known as nightglow - is a type of chemiluminescence that occurs all around the Earth, all the time. This is where light is emitted from chemical interactions between oxygen, nitrogen, and other molecules in the upper atmosphere. Auroras, on the other hand, are caused by charged solar particles colliding with Earth's atmosphere.

The striking image was snapped by Nasa's Aqua satellite between June 22 and Dec. 31, 2023. It was during an active eruption phase of the volcano, known as Klyuchevskoy or sometimes Klyuchevskaya Sopka - an area home to more than 300 volcanoes.

Astronauts have conducted 275 spacewalks since the station opened - one of the riskiest jobs an astronaut will ever undertake. Advertisement Backdropped by New Zealand and the Cook Strait in the Pacific Ocean, astronauts Robert Curbeam and Christer Fuglesang participate in an extravehicular activity, December 12, 2006. Their job was to support the construction of the orbital outpost, and proved the source of quite the stellar image. 7 False-color images combine and rearrange colour channels from multiple sources to visualise new details Credit: Don Pettit/X Ganges river The Ganges river, the world's largest river delta, was photographed in near-infrared from the ISS by Pettit. Advertisement The ISS utilises near-infrared imagery for various scientific purposes, including atmospheric studies and Earth observation. It is key to capturing images of the Earth's airglow, clouds, and other surface features during nighttime. The end result are incredible false-colour images that show Earth in a completely new light. False-color images combine and rearrange colour channels from multiple sources to visualise new details. Advertisement These details are either things that cannot be seen by the human eye - or aspects that may be obscured in true colour images, such as healthy vegetation or different soil types.

See the stunning winners of the 2025 Milky Way Photographer of the Year contest
When you buy through links on our articles, Future and its syndication partners may earn a commission. The honorees for the 2025 Milky Way Photographer of the Year contest are in, and they're stunning. Created in 2018 by photographer Dan Zafra, the contest showcases shots of the Milky Way taken from around the globe, highlighting gorgeous landscapes on Earth laid out under the twinkling night sky. This year's winners include shots from places as diverse as Namibia, the Himalayas, New Zealand and Yemen. There's even a photo taken from space. Photographer: Xingyang Cai Location: Big Sur, California This photograph, titled "Starlit Ocean: A Comet, the setting Venus, the Milky Way, and McWay Falls," was taken during the approach of Comet Tsuchinshan-ATLAS (C/2023 A3) in fall 2024. The comet streaks above the Pacific and a setting Venus at McWay Falls in Big Sur. Photographer: Sergio Montúfar Location: Acatenango volcano, Guatemala Photographer Sergio Montúfar captured this stunning image of two types of fire in the sky at Acatenango volcano in Guatemala in June 2024. "Above, the Milky Way stretched diagonally across the sky, a mesmerizing band of stars contrasting with the chaos below," Montúfar wrote in his description of the photograph. "As the volcano erupted, the ash plume rose vertically, forming an acute angle of about 45 degrees with the galaxy's diagonal path, creating a stunning visual contrast between Earth's fury and the cosmos' serenity." Montúfar used a wide-angle lens (f/2.8), an ISO of 3200, and a 10-second exposure to capture the light of the Milky Way and the light of the volcano at the same time. Photographer: Ethan Su Location: Hehuan Mountain Dark Sky Park, Taiwan An explosion of alpine rhododendrons provides a stunning foreground to this view of the Milky Way from Mount Hehuan in central Taiwan. A solar flare from the sunspot AR3664 added a slight airglow to the scene, while clouds blocked light pollution from distant urban areas. Photographer: Don Pettit Location: Earth orbit Astronaut Don Pettit captured this image of Earth against the Milky Way from the Cupola of the International Space Station. City lights seem to mirror the jewel-like glow of the galaxy in the background of the image. "There are over eight billion people that call this planet home," Pettit wrote. "There are seven of us that can say the same for [the] Space Station. What a privilege it is to be here." Related: May's best stargazing week has begun. How to see a lion, an upside-down bear, a mini 'planet parade' — and more. Photographer: Benjamin Barakat Location: Socotra, Yemen Four years of scouting Socotra, a Yemeni island in the Indian Ocean, led photographer Benjamin Barakat to this grove of bottle trees (Dendrosicyos socotranus), a species that's unique to the island. These trees' thick trunks allow them to store water to survive Socotra's dry climate. The Milky Way decorates this one-in-a-galaxy site like a bangle of jewels. Photographer: Tanay Das Location: Zanskar, Himalayas Celestial fire and Earthly ice meet in this shot taken at Lake RT5, which sits 18,700 feet (5,700 meters) high in the Himalayas. Photographer Tanay Das camped by this lake to capture this shot of the Milky Way. "I was in awe of the incredible airglow illuminating the Himalayan skies," Das wrote. "The raw image had even more intense colors, but I toned them down to stay true to reality. This was undoubtedly one of the most unforgettable nights I've ever spent in the heart of the Himalayas." Photographer: Max Inwood Location: Lake Tekapo, New Zealand Lupines bloom on New Zealand's South Island in a purple feast for the eyes. The dark skies of New Zealand's Mackenzie Basin — along with a lot of patience — enabled this shot. "I had to wait until the early hours of the morning for the wind to calm down, but eventually everything became still, and I was able to capture this image," photographer Max Inwood wrote. "Above the flowers, you can see the band of the outer Milky Way, alongside the constellations Orion, Gemini, and the Pleiades. Joining them are the bright planets Jupiter and Mars, with a strong display of green airglow visible along the horizon." Photographer: Burak Esenbey Location: Karas region, Namibia The Milky Way slashes across the sky behind cacti and two quiver trees (Aloidendron dichotomum) in Namibia. This was photographer Burak Esenbey's second photography trip to the area, and he found this spot on a location-scouting excursion. "Getting everything in focus was a bit challenging, as I had to get extremely close to the cactus without getting poked," he wrote in his description of the image. Photographer: Mike Abramyan Location: Alabama Hills, California Photographer Mike Abramyan wanted to photograph the Perseid meteor shower from the Canadian Rockies, but wildfires drove him westward and southward to California's Eastern Sierra, where he captured this stunning image of the Milky Way superimposed with each meteor he photographed — as if they'd all streaked across the sky at the same time.

The salt flats of Salinas Grandes in northern Argentina begged for a nighttime photoshoot, despite the challenges of camping on desiccated salt flats at an elevation of nearly 17,000 feet (5,200 m). "I believe I haven't truly experienced a place until I see it at night," Heis wrote. "Nighttime feels more intimate, mysterious, and adventurous — a moment when the senses sharpen and you connect with your surroundings in a deeper way."
