NASA recently captured a summertime spectacle in orbital imagery of the Black Sea, as eerie-looking swirls of turquoise could be seen swarming in its waters.
The curious curling features were observed by astronauts aboard the International Space Station in May, and more recently by the Ocean Color Instrument (OCI) on NASA’s Plankton, Aerosol, Cloud, Ocean Ecosystem (PACE) satellite on June 22, 2026, as it passed over the body of water that marks the boundary between Europe and Asia.
The vibrant oceanic display is believed to be the result of summertime blooms of coccolithophores, which begin surging in ocean waters near the shoreline in warmer weather months.
These phytoplankton are armored in plates composed of calcium carbonate, which can often cause discoloration in ocean waters as the blooms occur, which are driven by nutrients entering ocean waters that are often carried from inland sources.
Earlier this year, a similar turquoise spectacle occurred in Atlantic waters along the eastern United States, as coccolithophores surged in numbers as temperatures rose, and meltwater in mountainous regions made its way downstream, carrying vital nutrients which were deposited in coastal waters after they made their way downstream.
Unlike coccolithophores, which generally brighten the color of ocean water in the spring and early summer, later in the year another kind of microscopic organism, known as diatoms, can darken the water due to the silica shells that encase their microscopic bodies.
Similar orbital color shows were observed in recent weeks within the narrow waters of the Bosporus Strait, which separates Turkey as it parts Asia Minor and Thrace. In the recent photos obtained from the ISS, the entire Bosporus can be seen illuminated in turquoise as its waters have been flooded with coccolithophores.
Apart from the odd but beautiful swirling patterns they produce as these phytoplankton are carried by ocean currents, these colorful creatures also provide a more practical benefit, since they can be leveraged by remote sensing technologies to help study the dynamics of these blooms when they occur.
Additionally, these microscopic creatures can also make significant contributions to oceanic carbon cycles, since the creatures sink to the seafloor at the end of their life cycles, carrying carbon they’ve absorbed with them. Once deposited on the ocean floor, this carbon can be maintained at such depths for long periods.
Additional information about the recent coccolithophore blooms in the Black Sea, along with other imagery of our planet as seen from space, can be found at NASA’s Earth Observatory page.

NASA’s safety advisers say that while the agency and Boeing make progress in addressing problems with the CST-100 Starliner, it could be up to a year before it flies again.

Russian cosmonaut Aleksandr Samokutyaev, who served twice as a crew member aboard the International Space Station (ISS), including during the final US space shuttle mission in 2011, has died at the age of 56.
With Samokutyaev's death on Wednesday, he becomes the first former ISS long-duration resident to die in the 26 years that the space station has been a home to 155 other cosmonauts and astronauts as expedition crew members. The cause of his death is unknown.

Ten days ago, in a moment of very high drama in orbit, NASA directed its astronauts living on the International Space Station to briefly seek emergency refuge in a Crew Dragon spacecraft.
Since then, neither the US space agency nor Roscosmos has provided additional public information about the situation in orbit. But according to sources who spoke to Ars, following the spectacle in space, the problem has been successfully fixed.
At issue were persistent cracks in a small area of the International Space Station attached to the Russian Zvezda service module, known as the PrK module. The problem has been ongoing since 2019, and Russian astronauts have been attempting various fixes, often using a sealant called Germetall-1.

NASA's Artemis II crew are the fastest people alive, and now they have the patch to prove it.
Mission Commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen (the latter with the Canadian Space Agency) spent 10 days in early April flying by the Moon. Their journey took them farther away from Earth than any humans have gone (52,756 miles [406,771 km]) and then, on the way back on board their Orion spacecraft Integrity, they sped up to about 24,664 miles per hour (39,693 k/ph) reentering the atmosphere.
Only three other people in history have traveled faster. NASA's Apollo 10 astronauts Thomas Stafford, John Young, and Eugene Cernan set the record for the highest speed attained by a crewed vehicle relative to the Earth's surface: 24,791 mph (39,897 kph) on May 26, 1969.

Humans do not just visit space; they live there, but a major part of that is coming to an end. The platform that made the longest continuous human presence in space possible is becoming history.
With NASA and its partners beginning preparations for the destructive end of the International Space Station (ISS) as soon as 2030, those who collect, curate, and study the station are now asking how to preserve the historic and culturally significant artifact, given that it is far too large and complex to keep intact.
The Smithsonian National Air and Space Museum on Thursday hosted a three-part panel discussion, bringing together space program officials, museum curators, an archeologist, and an astronaut to begin answering the why, what, and how the ISS might be saved. The sessions were part of the American Institute of Aeronautics and Astronautics' (AIAA) ASCEND conference in Washington, DC.

NASA confirmed Thursday that the Russian segment of the International Space Station has begun leaking atmosphere into space again. It's an old problem that NASA recently hoped was resolved.
For more than half a decade, engineers from Roscosmos and NASA have been tracking the leak rate from a small Russian module attached to the space station that leads to a docking port. The source of these leaks, microscopic structural cracks, have been difficult to find and address.
In January, NASA said that after multiple inspections and sealant applications, the pressure inside this segment, known as the PrK module, had reached a "stable configuration." The PrK module is essentially a transfer tunnel attached to the Zvezda Service Module on the Russian segment of the space station.
