In Photos: April's Pink ‘Micro Moon' Lights Up Spring Skies Worldwide
The night sky was ablaze with moonlight on Saturday, April 12, 2025, as the first full moon of spring — known as the pink moon — rose in dusk. Also the smallest full moon of the year, it wasn't pink in color, instead appearing in the east as an orange orb.
Here are all the best images of April's full pink moon from around the world, from San Francisco to Istanbul, Kashmir and Sydney.
Named after the pink phlox flowers that bloom in spring in parts of North America rather than for the moon's color, April's pink moon reached its full phase at 8:23 p.m. EDT, aligning almost perfectly with moonrise in parts of North America.
As it appeared in the east, Earth's atmosphere dimmed and reddened its light, causing its surface to glow in subtle orangey hues. Like all full moons viewed at moonrise, its size was exaggerated, not by physics but by the "moon illusion" — tricks on our perception when the moon is near the horizon phenomenon that makes the full moon seem bigger than it is.
Even that illusion was stretched during the appearance of this, the smallest full moon of the year. That happened because the moon's orbit of Earth is slightly elliptical. That means there's always a date when it's closest to Earth (perigee) and farthest (apogee).
A perigee full moon is better known as a 'supermoon,' which looks slightly bigger than average, while an apogee full moon — sometimes called a "micro" moon — looks somewhat smaller than average. The latter scenario describes April's full pink moon.
April's full moon was this year considered the 'Paschal Moon,' the full moon used to calculate the date of Easter Sunday. It traditionally falls on the Sunday after the first moon after the Spring equinox, which occurred on March 20 this year.
The moon reached fullness on April 13 in Universal Time, but on April 12 only in North American time zones, meaning Easter was set for Sunday, April 20, 2025. The next full moon, the flower moon, will occur on Monday, May 12, 2025.

Study says California is overdue for a major earthquake. Does that mean ‘the big one' is coming?
Unlike other earthquake-prone places around the planet, California is overdue for a major quake, according to a recent study. But that doesn't mean a catastrophic event like the 1906 San Francisco earthquake is on the verge of striking. 'A fault's 'overdue' is not a loan payment overdue,' said Lucy Jones, founder of the Dr. Lucy Jones Center for Science and Society and a research associate at the California Institute of Technology, who wasn't part of the work. The new study reported that a large share of California faults have been running 'late,' based on the expected time span between damaging temblors. The researchers compiled a geologic data set of nearly 900 large earthquakes on active faults in Japan, Greece, New Zealand and the western United States, including California. Faults are cracks in the planet's crust, where giant slabs of earth, known as tectonic plates, meet. The Hayward Fault is slowly creeping in the East Bay and moves around 5 millimeters per year, according to the U.S. Geological Survey. But sometimes plates get stuck and pressure builds. Earthquakes occur when plates suddenly slip, producing a jolt of energy that causes the ground to shake. Scientists study ruptured rock layers deep beneath the surface to estimate when large earthquakes occurred in the past. In the new study, the authors collected data stretching back tens of thousands of years. For a region spanning the Great Basin to northern Mexico, this paleoearthquake record stretched back about 80,000 years. For California, the record extended back about 5,000 years. The scientists used these records to calculate how much time typically passes between large surface-rupturing earthquakes around the planet. The average interval was around 100 years for some sites on the San Andreas Fault; it was 2,100 years on the less famous Compton thrust fault beneath the Los Angeles area. About 45% of the faults analyzed for California are running behind schedule for a major earthquake, meaning that more time has passed since the last large quake on a fault than the historical average. In the other regions studied, this statistic ranged from 9% to 18%. The researchers' analysis only included large surface-rupturing earthquakes. It didn't include the magnitude 6.9 Loma Prieta earthquake in 1989, which was below the magnitude 7 threshold that the study authors used for quakes on the San Andreas Fault. The authors associated seismic punctuality with slip rates, or how fast the two sides of a fault move past each other. 'Our analysis showed that the faster the faults are moving, the more likely it is that they will appear overdue,' said study author Vasiliki Mouslopoulou, a senior scientist at the National Observatory of Athens, in Greece. In tectonically active California, the San Andreas Fault has a particularly high slip rate. The Pacific and North American plates slide past each other an average of more than inch per year in some spots. 'Faults in California are among the fastest-slipping faults in the world,' Mouslopoulou said, adding that other factors are also probably contributing due to the pattern of chronically late large earthquakes. Previous studies had also shown that seismic activity has been unusually subdued in California, compared with paleorecords. A 2019 study reported that there's been a 100-year hiatus in ground-rupturing earthquakes at a number of paleoseismic sites in California, including on the San Andreas and Hayward faults. The authors of the 2019 study treated large earthquakes at these sites as independent events, akin to flipping pennies and counting how many turn up heads. They calculated a 0.3% probability that there'd be a 100-year hiatus in ground-rupturing quakes across all the California sites. Scientists have suggested that there could be earthquake 'supercycles,' with large quakes occurring in clusters, with less active periods in between. 'There are these longer-term, decadal, century-long ups and downs in the rate of earthquakes,' Jones said. Potentially, California is in a quiet time and large earthquakes are currently less likely. Katherine Scharer, a U.S. Geological Survey research geologist who wasn't part of the new research, commended the authors of the study, explaining that compiling the paleoseismic records was a 'tremendous amount of work' and will enable more scientists to investigate earthquakes. California's relatively sparse big earthquake activity could be connected to the geometry of its faults. While the analyzed faults in California were more or less in line with each other, those in other regions resembled 'a plate of spaghetti,' Scharer said. 'From the study, I think you would say that the main California faults are mechanically different somehow than the averages from these other places,' Glenn Biasi, a geophysicist with the U.S. Geological Survey, who wasn't part of the new work. Biasi emphasized that it's impossible to say if California's faults are truly overdue for a big earthquake. 'The faults slip on their own schedule and for their own reasons,' Biasi said. Scientists can't accurately predict large earthquakes in advance but paleoearthquake data could help. The authors of the new study found that, excluding California's recent lack of large earthquakes, faults around the entire planet have generally produced surface-rupturing quakes at intervals expected from paleoearthquake and historic records. Considering such data could improve earthquake forecasts, Mouslopoulou said.

Finland's AIATELLA secures funds for AI cardiovascular imaging solutions
Finnish startup AIATELLA has raised €2m ($2.27m) in financing to develop and scale its cardiovascular imaging technology powered by AI. The investment will support the company in conducting clinical trials and further developing its ultrasound-based preventative screening tool, which can identify and quantify carotid artery narrowing within minutes. Nordic Science Investments spearheaded the funding round, with contributions from Specialist VC, Business Finland, and Harjavalta Ventures, among other investors. The Automated Image Measurement technology of the startup leverages images from ultrasound, computed tomography, and magnetic resonance imaging to analyse vascular imaging. This multimodal technology identifies abnormalities and quantifies changes over time in those at risk. It significantly reduces the time specialists spend on manual image measurements and documentation. As a result, clinicians can dedicate more time to patient care. AIATELLA is currently navigating the medical approval processes in several European and North American countries, including France, the US, and the UK. AIATELLA co-founder and CEO Jack Parker said: 'Our technology helps medical professionals analyse imaging much more efficiently, and at an earlier stage, so patients can get help before it's too late.' Initially applied to the aorta artery, AIATELLA's vision extends to encompass all blood vessels in the body with its technology. The startup noted that it is also developing a portable ultrasound-based screening technology for mass screening of individuals prior to the occurrence of symptoms. This approach aims to facilitate early detection of cardiovascular diseases, which are a major cause of mortality worldwide. The technology has already been employed in the UK and Finland at screening events, where it has helped identify potentially at-risk individuals. AIATELLA also aims to gather data on the presentation and progression of cardiovascular conditions across different sexes and ethnicities, as symptoms can vary widely among these different groups.

Iron from steel and coal manufacturing is changing the North Pacific ecosystem: Study
Iron released from coal combustion and steel production is altering the ecosystem in a critical part of the North Pacific, a new study has found. About 39 percent of dissolved iron in the uppermost layer of the ocean is rooted in human industrial activity, according to the study, published on Monday in the Proceedings of the National Academy of Sciences. Iron is essential for the growth of microscopic phytoplankton in the ocean, but industrial emissions contain aerosolized iron, which quickly dissolves in the ocean and disrupts nutrient balances, the authors noted. These airborne metals, they explained, can flow to distant lands or oceans before getting scrubbed from the atmosphere via rain. 'This is an example of the large-scale impact that human pollution can have on marine ecosystems that are thousands of miles away from the source,' lead author Nick Hawco, an assistant professor in oceanography at the University of Hawaii Manoa, said in a statement. Hawco and his colleagues sampled oceanic water and phytoplankton samples across the North Pacific Transition Zone — an area just north of Hawaii — on four expeditions between 2016 and 2019. They also evaluated the properties of iron in these waters to identify whether the unique 'signature' of industry-generated iron was present. The scientists observed that the phytoplankton in the region tend to be iron-deficient during the spring and that a surge in iron supply boosts their seasonal bloom. But that burst also causes these microscopic marine algae to deplete other nutrients more rapidly, which then leads to a crash later in the season, according to the study. In tandem with their observations of this boom-and-bust trend, the researchers also confirmed the presence of industrial iron in the region, thousands of miles away from any possible source. 'The ocean has boundaries that are invisible to us but known to all sorts of microbes and animals that live there,' Hawco said. The North Pacific Transition Zone, he explained, is one of these critical boundaries, as this region separates low-nutrient ocean whirlpools from nutrient ecosystems in the north. 'With more iron coming into the system, that boundary is migrating north, but we are also expecting to see these boundaries shift northward as the ocean warms,' Hawco added. Similar such effects may have occurred in areas of the North Atlantic during the industrialization of North American and Europe, as coal-powered shipping saw an uptick in the early 20th century, the authors noted. While Hawco acknowledged that the changes impacting the North Pacific Transition Zone may not necessarily be entirely negative, he warned that regions closer to Hawaii are among those reaping the negatives of these developments. 'It's a one-two punch: industrial iron is impacting the base of the food web and the warming of the ocean is pushing these phytoplankton-rich waters further and further away from Hawaii,' he said. Going forward, Hawco and his colleagues added that they are working on developing new techniques to monitor iron nutrition in ocean plankton. Having greater insight into the metal's presence, they stressed, could help shed light on how changes in iron supply could be influencing ocean life. Copyright 2025 Nexstar Media, Inc.
