-An eerie spiral lit up the European skies. Here’s why such light shows are becoming more common [[https://kra30c.cc/|kraken тор]]

-The shapes can seem to appear out of nowhere: an undulating S-like spiral streaking across the European skies or a glowing orb trailing above the North American coast.
+The world is betting heavily on carbon capture — a term that refers to various techniques to stop carbon pollution from being released during industrial processes, or removing existing carbon from the atmosphere, to then lock it up permanently.
-Such strange light shows have been a known feature of rocket launches for years. But as humanity rapidly increases the number of objects propelled into space — more people are inadvertently witnessing the phenomena.
+The practice is not free of controversy, with some arguing that carbon capture is expensive, unproven and can serve as a distraction from actually reducing carbon emissions. But it is a fast-growing reality: there are at least 628 carbon capture and storage projects in the pipeline around the world, with a 60% year-on-year increase, according to the latest report from the Global CCS (Carbon Capture and Storage) Institute. The market size was just over $3.5 billion in 2024, but is projected to grow to $14.5 billion by 2032, according to Fortune Business Insights.
-“We’re not used to seeing things that are happening in space in these very low (atmospheric) densities,” said Jonathan McDowell, an astrophysicist and astronomer at the Harvard-Smithsonian Center for Astrophysics, referring to the thin atmosphere that exists at high altitudes and in Earth’s orbit.
+Perhaps the most ambitious — and the most expensive — type of carbon capture involves removing carbon dioxide (CO2) directly from the air, although there are just a few such facilities currently in operation worldwide. Some scientists believe that a better option would be to capture carbon from seawater rather than air, because the ocean is the planet’s largest carbon sink, absorbing 25% of all carbon dioxide emissions.
-When a SpaceX Falcon 9 rocket took off from Florida last week — flying northeastward as it headed for Earth’s orbit to drop off a spy satellite for the US military — it put on a show for millions over the United Kingdom and the European continent.
+In the UK, where the government in 2023 announced up to £20 billion ($26.7 billion) in funding to support carbon capture, one such project has taken shape near the English Channel. Called SeaCURE, it aims to find out if sea carbon capture actually works, and if it can be competitive with its air counterpart.
-Shortly after launch, social media users began to report “strange shapes” dancing in the sky.
+“The reason why sea water holds so much carbon is that when you put CO2 into the water, 99% of it becomes other forms of dissolved carbon that don’t exchange with the atmosphere,” says Paul Halloran, a professor of Ocean and Climate Science at the University of Exeter, who leads the SeaCURE team.
-The scene was “likely to be caused by the SpaceX Falcon 9 rocket,” according to a post on X that the Met Office, Britain’s national weather service, shared after the launch.
+“But it also means it’s very straightforward to take that carbon out of the water.”
-The viral images were reminiscent of the “jellyfish” phenomenon that has accompanied some SpaceX launches from Florida and California. Visible from the North American coasts, the “jellyfish” is marked by a massive teardrop-shaped streak of light that grows and stretches as the rocket flies.
+Pilot plant
+SeaCURE started building a pilot plant about a year ago, at the Weymouth Sea Life Centre on the southern coast of England. Operational for the past few months, it is designed to process 3,000 liters of seawater per minute and remove an estimated 100 tons of CO2 per year.
-Despite their similarities, however, experts said the phenomena of the jellyfish and spiral are distinct.
+“We wanted to test the technology in the real environment with real sea water, to identify what problems you hit,” says Halloran, adding that working at a large public aquarium helps because it already has infrastructure to extract seawater and then discharge it back into the ocean.
-A ghostly spiral
-The eerie bat signal-like spiral following SpaceX’s March 24 military satellite launch formed after the rocket had already made its delivery. The vehicle was preparing to plunge out of orbit and back into Earth’s atmosphere, twirling toward a safe splashdown in the ocean — and leaving fuel in its wake.
-Such maneuvers made to dispose of rocket bodies are common after launches.
+The carbon that is naturally dissolved in the seawater can be easily converted to CO2 by slightly increasing the acidity of the water. To make it come out, the water is trickled over a large surface area with air blowing over it. “In that process, we can constrict over 90% of the carbon out of that water,” Halloran says.
-The Falcon 9 is designed to break into two parts — or “stages.”
-The first stage is the bottommost portion of the rocket with nine engines that fire up at liftoff, powering the 230-foot (70-meter) vehicle off the ground. The first-stage booster is also the same part that SpaceX routinely guides to landing after launch and reuses to save money.
