Failed Soviet spacecraft could crash to Earth this week — here's where it might hit (map)
A failed Soviet spacecraft that was mistakenly trapped in Earth orbit more than 50 years ago is expected to finally crash back to our planet this week.
Experts predict that the spacecraft, called the Kosmos 482 Descent Craft, will make its final, fiery plunge through the atmosphere sometime between May 8 and May 12, traveling at an estimated speed of 150 mph (242 km/h) as it careens through the sky like a meteor. Built to withstand a trip through the dense atmosphere of Venus, the 3-foot-wide (1 meter), 1,091 pound (495 kilograms) lander is likely to stay in one piece as it falls to Earth like a cosmic cannonball.
But where will Kosmos 482 land, and are any major cities in its potential path?
Unfortunately, at the moment, nobody knows for sure where Kosmos 482 will hit — and its potential landing area covers most of the planet. Given the satellite's current orbit, it could ultimately land anywhere between 52 degrees north and 52 degrees south latitude, Marco Langbroek, a lecturer in space situational awareness at Delft Technical University in the Netherlands who discovered the lander's imminent return, wrote in a blog post. Here's what that area looks like, shown in orange on the map below:
The projected landing zone encompasses an enormous area on both sides of the equator. This broad swath includes the entire continental United States, all of South America, Africa and Australia, and most of Europe and Asia south of the Arctic Circle. (The Arctic Circle begins just above 66 degrees north latitude). Virtually every major city on Earth, from New York to London to Beijing, falls within this zone.
That sounds bad — but you shouldn't worry: The odds of the runaway Kosmos spacecraft hitting any given populated area are exceptionally slim. With roughly 71% of our planet's surface covered in water, it is overwhelmingly likely that Kosmos 482 will land in the ocean, as most pieces of deorbited space debris do.

The odds of the spacecraft falling directly onto your head are probably "the usual one-in-several-thousand chance" associated with falling space debris, Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, wrote in a blog post.
Experts won't be able to narrow down Kosmos 482's potential landing zone until it actually begins its descent through the atmosphere, which is currently predicted to happen on May 10, give or take a couple days.
The Kosmos 482 probe was made and launched by the U.S.S.R. in 1972 as part of the Soviet Union's Venera program to explore Venus. The program achieved success with the Venera 7 and 8 probes, which were the first two spacecraft to successfully land on Venus in 1970 and 1972, respectively.
Kosmos 482 was built as a sister probe to Venera 8. But due to a malfunction with the Soyuz rocket that lofted Kosmos 482 into space, the probe failed to achieve enough velocity to reach Venus, instead settling into an elliptical orbit around Earth.

Soon after its botched launch, Kosmos 482 broke into several pieces. The probe's main body reentered Earth's atmosphere on May 5, 1981, while the Descent Craft remained in its unintended orbit for almost 53 years — until now.
Kosmos 482 is just one of more than 1.2 million pieces of space debris measuring larger than 0.4 inches (1 centimeter) in size, and one of roughly 50,000 pieces of space junk measuring more than 4 inches (10 cm), according to a recent report from the European Space Agency (ESA). Orbital collisions and uncontrolled reentries are becoming increasingly common, with "intact satellites or rocket bodies … now re-entering the Earth atmosphere on average more than three times a day," according to the ESA report.

10 bizarre 'dark voids' appear in the skies over uninhabited island near Antarctica — Earth from space
When you buy through links on our articles, Future and its syndication partners may earn a commission. QUICK FACTS Where is it? Heard Island, Indian Ocean [-53.116414344, 73.51793263] What's in the photo? An unusual stream of von Kármán vortices trailing off a hidden peak Which satellite took the photo? Landsat 8 When was it taken? May 3, 2016 This striking satellite photo shows 10 swirling "dark voids" that appeared above an uninhabited volcanic island in the Indian Ocean. The black spots are the result of atmospheric cloud vortices, but are oddly pronounced and significantly contorted compared to most other examples of this phenomenon. The spinning voids are trailing off Heard Island — an uninhabited Australian territory in the southern Indian Ocean, around 900 miles (1,500 kilometers) north of Antarctica. The cloud-obscured landmass has a surface area of around 142 square miles (368 square kilometers). On average, the dark spots are around 8 miles (13 km) wide, decreasing slightly in size the further they have traveled, according to NASA's Earth Observatory. They are initially moving away from the island in a northeasterly direction (left to right). The spinning holes are the result of a phenomenon known as von Kármán vortices, which occur when a prevailing wind encounters a landmass, disturbing the airflow and creating "a double row of vortices which alternate their direction of rotation," according to the National Oceanic and Atmospheric Administration. They are named for Theodore von Kármán, a Hungarian-American physicist, who was the first to describe this natural phenomenon. In this case, the vortices are being created by Mawson Peak, a 9,000-foot-tall (2,700 meters) active volcano sat at the heart of Heard Island. Related: See all the best images of Earth from space Normally, von Kármán vortices create long trails of swirling clouds that get caught up in the disrupted air flows. The cloud streams are normally perfectly straight, such as a series of parallel vortex streams that emerged side-by-side off the Atlantic coast of Africa in 2015 (see above). But in this case, the vortex stream appears to bend almost 90 degrees midway through the stream. This change in direction was most likely caused by a sporadic burst of the intense westerly winds that frequently blow across the area around Heard Island at speeds over 50 mph (80km/h), known as the "Furious Fifties," according to the Earth Observatory. In most examples of von Kármán vortices, the resulting cloud trails can be quite wispy, tracing out the subtle variations in the invisible air currents, such as examples observed over Mexico's Guadalupe Island in 2012 and above Svalbard's Bear Island in 2023. MORE EARTH FROM SPACE —Gravity waves spark pair of perfect cloud ripples above uninhabited islands —Mysterious, slow-spinning cloud 'cyclone' hugs the Iberian coast —Giant, near-perfect cloud ring appears in the middle of the Pacific Ocean However, in this photo, the wispy trails are replaced by a string of concentrated holes, or gaps, within the clouds. This is probably due to exceptionally thick cloud coverage, which can be disrupted only at the heart of each spinning section within the vortex stream. Mawson Peak is smaller than most of the peaks that regularly produce von Kármán vortices, making it slightly rarer for the cloud swirls to emerge there. However, Heard Island has produced more traditional vortex streams in the past, such as one showing in November 2015. Solve the daily Crossword

An icy supervolcano eruption on Pluto may have left a massive crater on the frozen world
When you buy through links on our articles, Future and its syndication partners may earn a commission. A landmark on Pluto that was previously designated as an impact crater may actually be the caldera of a supervolcano that has exploded in the past few million years, new research suggests. When NASA's New Horizons mission flew by Pluto in 2015, it revealed a geologically rich world, rather than the cold, dark landscape many had anticipated. Almost immediately, researchers identified two features, called Wright Mons and Piccard Mons, that were strongly suspected to be icy volcanoes, and further study confirmed their identity. But not every cryovolcano was easy to spot. The suspected supervolcano, Kiladze, was initially classified as an impact crater. However, now scientists suspect it's something else. "We evaluated the possibility of the depression as a cryovolcanic caldera versus having an impact crater origin," said Al Emran, a planetary scientist at the Jet Propulsion Laboratory in California. Emran presented his team's results in July at the Progress in Understanding the Pluto System: 10 Years After Flyby conference in Laurel, Maryland. "We think it's more like Yellowstone Caldera in Wyoming," Emran said. At least two of Yellowstone's eruptions, millions of years ago, reached supervolcano status. Impact crater or caldera? Kiladze remains listed as a crater. But the rich supply of water ice surrounding the bowl-shaped feature sparked Emran's curiosity, and he wondered if it might be a cryovolcano instead. At first glance, the elongated oval bears a strong similarity to an impact crater. It's large, with an average diameter of 2.5 miles (4 kilometers). Its walls are irregularly shaped, and the complex features it would require could easily have been eroded by Pluto's active surface processes. The landscape itself is marked by pits and other geological features, many of which have collapsed. If an incoming impactor broke through the surface and exposed veins of frozen lava beneath, it could have created the explosive distribution of water ice seen on the surface. But when Emran dug into the topography maps of Pluto created by the New Horizons team, he realized there was a problem: The crater was too deep. Across the solar system, crater depth scales with crater diameter in a predictable way, and the same law appeared to hold true for other craters on Pluto — but for not Kiladze. At best, estimates put an impact crater of its size at 1.7 miles (2.74 km) wide. But with the activity flowing across Pluto, material would have been more likely to fill in the crater over time, making it even shallower. Haze particles would have piled up, and melting or slumping ices would have fallen inward. However, Kiladze isn't shallower than projected; it's deeper. Parts of the basin reach 2.5 deep, and the entire site averages nearly 2 miles (3 km) in depth. For these reasons, Emran and his colleagues suspect that Kiladze is a caldera, a massive depression created by the eruption and subsequent collapse of a volcano. Magma — or cryomagma — spewing from the surface rapidly over a short period of time can weaken the supporting material, causing it to collapse inward on itself. Despite the supervolcano's collapse, the eruptive power of Kiladze would have been impressive. Emran and his colleagues calculated that the explosion could have ejected as much as 240 cubic miles (1,000 cubic kilometers) of icy cryomagma across the surrounding region, achieving the definition of a supervolcano. Although Yellowstone has erupted more than 80 times over its lifetime of more than 2 million years, only two explosions have been classified as supervolcanic. Kiladze may have blasted out its cryomagma in a single explosive event, or it may have spread its eruptions over time. Either way, its most recent event spewed water ice at least 60 miles (100 km). Emran suspects that estimate is low, however, as more water ice is likely visible at resolutions smaller than New Horizons could reach. "One or more cataclysmic explosive eruptions that resulted in the excavation and collapse of what is seen as the Kiladze caldera would be expected to scatter the water-ice cryomagma widely for a thousand or more kilometers, leaving exposures too small to be seen in the data at hand," the authors wrote in a paper recently published in The Planetary Science Journal. Clues in the ice Kiladze sits just north of Sputnik Planetia, the icy heart to Pluto. Although much of the dwarf planet's surface is covered with a variety of ices, very little of the surface matches what you might find in your freezer at home. Temperatures on Pluto are so cold that water ice serves as the bedrock for the dwarf planet, while other ices pile on top. But in the neighborhood surrounding Kiladze, water ice stretches across the surface. The ice has traces of an unidentified ammoniated compound. "It's difficult to determine the exact composition," Emran said. In fact, that particular signature of ammonia is not seen anywhere else on Pluto. Ammonia may be what allows the frigid ice to flow. Its addition lowers the freezing point of water, allowing it to remain liquid for longer periods. Beneath the surface, pockets of water and ammonia could have avoided freezing as Pluto's bedrock solidified. Eventually, tectonic pressure could have driven the icy magma to the surface, spewing it across the landscape around Kiladze, Emran explained. The mysterious traces of ammonia could also help to date the cryovolcano. Pure ammonia is quickly obliterated by the solar wind, ultraviolet particles and cosmic rays. Its faint presence suggests that the latest eruption occurred fairly recently in Pluto's history, Emran said. Pluto's haze can help to nail down geological activity. The light shroud covers the dwarf planet — a result of methane and other gases jumping from solid to gas. As the particles grow, they eventually fall back to the surface and spread all over the dwarf planet. Grounded haze particles would cover the water ice like a blanket, obscuring signs of the cryolava, Emran explained. If such a layer had formed, New Horizons would have seen nitrogen-rich ice instead of signs of water-rich volcanism.

That process takes at least 3 million years, Emran said. That could mean Pluto isn't as frozen as previously thought. "If Kiladze erupted as recently as 3 million years ago, it would indeed suggest that Pluto's interior may still retain some residual warmth today," Emran said. "This aligns with the idea that cryovolcanism on Pluto could be ongoing or episodic." Solve the daily Crossword

Light pollution is encroaching on observatories around the globe – making it harder for astronomers to study the cosmos
When you buy through links on our articles, Future and its syndication partners may earn a commission. This article was originally published at The Conversation. The publication contributed the article to Expert Voices: Op-Ed & Insights. Outdoor lighting for buildings, roads and advertising can help people see in the dark of night, but many astronomers are growing increasingly concerned that these lights could be blinding us to the rest of the universe. An estimate from 2023 showed that the rate of human-produced light is increasing in the night sky by as much as 10% per year. I'm an astronomer who has chaired a standing commission on astronomical site protection for the International Astronomical Union-sponsored working groups studying ground-based light pollution. My work with these groups has centered around the idea that lights from human activities are now affecting astronomical observatories on what used to be distant mountaintops. Hot science in the cold, dark night While orbiting telescopes like the Hubble Space Telescope or the James Webb Space Telescope give researchers a unique view of the cosmos – particularly because they can see light blocked by the Earth's atmosphere – ground-based telescopes also continue to drive cutting-edge discovery. Telescopes on the ground capture light with gigantic and precise focusing mirrors that can be 20 to 35 feet (6 to 10 meters) wide. Moving all astronomical observations to space to escape light pollution would not be possible, because space missions have a much greater cost and so many large ground-based telescopes are already in operation or under construction. Around the world, there are 17 ground-based telescopes with primary mirrors as big or bigger than Webb's 20-foot (6-meter) mirror, and three more under construction with mirrors planned to span 80 to 130 feet (24 to 40 meters). The newest telescope starting its scientific mission right now, the Vera Rubin Observatory in Chile, has a mirror with a 28-foot diameter and a 3-gigapixel camera. One of its missions is to map the distribution of dark matter in the universe. To do that, it will collect a sample of 2.6 billion galaxies. The typical galaxy in that sample is 100 times fainter than the natural glow in the nighttime air in the Earth's atmosphere, so this Rubin Observatory program depends on near-total natural darkness. Any light scattered at night – road lighting, building illumination, billboards – would add glare and noise to the scene, greatly reducing the number of galaxies Rubin can reliably measure in the same time, or greatly increasing the total exposure time required to get the same result. The LED revolution Astronomers care specifically about artificial light in the blue-green range of the electromagnetic spectrum, as that used to be the darkest part of the night sky. A decade ago, the most common outdoor lighting was from sodium vapor discharge lamps. They produced an orange-pink glow, which meant that they put out very little blue and green light. Even observatories relatively close to growing urban areas had skies that were naturally dark in the blue and green part of the spectrum, enabling all kinds of new observations. Then came the solid-state LED lighting revolution. Those lights put out a broad rainbow of color with very high efficiency – meaning they produce lots of light per watt of electricity. The earliest versions of LEDs put out a large fraction of their energy in the blue and green, but advancing technology now gets the same efficiency with "warmer" lights that have much less blue and green. Nevertheless, the formerly pristine darkness of the night sky now has much more light, particularly in the blue and green, from LEDs in cities and towns, lighting roads, public spaces and advertising. The broad output of color from LEDs affects the whole spectrum, from ultraviolet through deep red. The U.S. Department of Energy commissioned a study in 2019 which predicted that the higher energy efficiency of LEDs would mean that the amount of power used for lights at night would go down, with the amount of light emitted staying roughly the same. But satellites looking down at the Earth reveal that just isn't the case. The amount of light is going steadily up, meaning that cities and businesses were willing to keep their electricity bills about the same as energy efficiency improved, and just get more light. Natural darkness in retreat As human activity spreads out over time, many of the remote areas that host observatories are becoming less remote. Light domes from large urban areas slightly brighten the dark sky at mountaintop observatories up to 200 miles (320 kilometers) away. When these urban areas are adjacent to an observatory, the addition to the skyglow is much stronger, making detection of the faintest galaxies and stars that much harder. When the Mt. Wilson Observatory was constructed in the Angeles National Forest near Pasadena, California, in the early 1900s, it was a very dark site, considerably far from the 500,000 people living in Greater Los Angeles. Today, 18.6 million people live in the LA area, and urban sprawl has brought civilization much closer to Mt. Wilson. When Kitt Peak National Observatory was first under construction in the late 1950s, it was far from metro Tucson, Arizona, with its population of 230,000. Today, that area houses 1 million people, and Kitt Peak faces much more light pollution. Even telescopes in darker, more secluded regions – like northern Chile or western Texas – experience light pollution from industrial activities like open-pit mining or oil and gas facilities. The case of the European Southern Observatory An interesting modern challenge is facing the European Southern Observatory, which operates four of the world's largest optical telescopes. Their site in northern Chile is very remote, and it is nominally covered by strict national regulations protecting the dark sky. AES Chile, an energy provider with strong U.S. investor backing, announced a plan in December 2024 for the development of a large industrial plant and transport hub close to the observatory. The plant would produce liquid hydrogen and ammonia for green energy. Even though formally compliant with the national lighting norm, the fully built operation could scatter enough artificial light into the night sky to turn the current observatory's pristine darkness into a state similar to some of the legacy observatories now near large urban areas. This light pollution could mean the facility won't have the same ability to detect and measure the faintest galaxies and stars.

In 2009, the International Astronomical Union declared that there is a universal right to starlight. The dark night sky belongs to all people – its awe-inspiring beauty is something that you don't have to be an astronomer to appreciate.
