☆ Turbulent skies of Vincent Van Gogh’s ‘The Starry Night’ may align with a scientific theory
▼ + stars: | 2024-09-19 | by ( Katie Hunt | ) edition.cnn.com time to read: +8 min

CNN —The dappled starlight and swirling clouds of Vincent van Gogh’s “The Starry Night” are thought to reflect the artist’s tumultuous state of mind when he painted the work in 1889. Now, a new analysis by physicists based in China and France suggests the artist had a deep, intuitive understanding of the mathematical structure of turbulent flow. Batchelor’s scaling mathematically represents how small particles, such as drifting algae in the ocean or pieces of dust in the wind, are passively mixed around by turbulent flow. “I think this physical relationship must be embedded in his mind so that’s why when he made this famous ‘Starry Night’ painting, it mimics the real flow,” Huang said. “What I take away from studies like this is that (van Gogh) captured some of this universality in the beautiful (‘Starry Night’),” Beattie added.

☆ Nova: ‘New star’ will appear in the night sky after stellar explosion
▼ + stars: | 2024-06-11 | by ( Ashley Strickland | ) edition.cnn.com time to read: +7 min

While a supernova is the explosive death of a massive star, a nova refers to the sudden, brief explosion from a collapsed star known as a white dwarf. The dwarf star remains intact, releasing material in a repetitive cycle that can occur for thousands of years. “It’s incredibly exciting to have this front-row seat.”T Coronae Borealis, otherwise known as the “Blaze Star,” is a binary system in the Corona Borealis that includes a dead white dwarf star and an aging red giant star. The red giant becomes increasingly unstable over time as it heats up, casting off its outer layers that land as matter on the white dwarf star. Cooke recalled that the last nova he witnessed — Nova Cygni in 1975 — had a similar brightness to what is expected from T Coronae Borealis.

NOAA has forecasted a "severe" geomagnetic storm to hit Earth this Friday, triggering aurora borealis. This storm comes as we approach solar maximum: the peak of solar activity during the sun's 11-year cycle. As a result, the National Oceanic and Atmospheric Administration issued a rare forecast for a "severe" G4 geomagnetic storm to hit Earth this Friday. NASADuring solar maximum, the sun develops more and larger sunspots, like the ones in region 3664, compared to quieter periods of solar activity. Severe geomagnetic storms like the one forecasted to hit this Friday are rare.

G4 storms are the second-strongest type of geomagnetic storm. "If geomagnetic storms were hurricanes, 'severe' would be category 4," according to SpaceWeather.com. Solar storms happen when the sun shoots powerful explosions of highly-energized and magnetic plasma called coronal mass ejections toward Earth. Also, a severe storm might disrupt GPS, so it's best to have a written record and directions to important locations, like hospitals.

☆ Someday, Earth Will Have a Final Total Solar Eclipse

The total solar eclipse visible on Monday over parts of Mexico, the United States and Canada was a perfect confluence of the sun and the moon in the sky. But it’s also the kind of event that comes with an expiration date: At some point in the distant future, Earth will experience its last total solar eclipse. That’s because the moon is drifting away from Earth, so our nearest celestial neighbor will one day, millions or even billions of years in the future, appear too small in the sky to completely obscure the sun. “We’ll only ever have annular eclipses,” said Noah Petro, a planetary scientist at NASA Goddard Space Flight Center, referring to “ring of fire” eclipses like the one that crossed the Americas in October. But putting an exact date on Earth’s final total solar eclipse is a serious computational challenge involving a variety of scientific disciplines.

On Wednesday, NASA’s Lucy spacecraft zoomed by its first asteroid target — and scientists on the mission were shocked to discover that the rock, named Dinkinesh, was actually two rocks. The binary consists of a larger, primary asteroid and a smaller “moon” orbiting around it, as seen in images that Lucy captured of the pair. “We knew this was going to be the smallest main belt asteroid ever seen up close,” Keith Noll, an astronomer and Lucy project scientist at the NASA Goddard Space Flight Center, said in a news release. Lucy will visit nine additional space rocks through 2033, part of NASA’s broader effort to glean knowledge about our celestial neighborhood. “The Trojans are the last big population of objects that we have not yet seen close up,” said Thomas Statler, a NASA planetary scientist on the mission.

☆ Scientists predicted Earth's ozone hole would balloon in size this year, but now admit their calculations were wildly off the mark

Scientists predicted that we'd see a huge ozone hole over the Antarctic in 2023. From September to mid-October, the ozone hole this year averaged 8.9 million square miles (23.1 million square kilometers), which is the 16th largest since satellites started tracking in 1979. It peaked this year at 10 million square miles (26 million square kilometers), about the size of North America. The ozone hole and thinning ozone layer has improved a bit thanks to the 1987 Montreal Protocol, when countries in the world agreed to stop producing many of the chemicals that deplete ozone, Newman said. The ozone hole was at its biggest in 2000 at nearly 11.6 million square miles (29.9 million square kilometers), according to NASA data.

CNN —A spacecraft left behind by US astronauts on the lunar surface could be causing small tremors known as moonquakes, according to a new study. The lunar surface is an extreme environment, oscillating between minus 208 degrees Fahrenheit (minus 133 degrees Celsius) in the dark and 250 degrees Fahrenheit (121 degrees Celsius) in direct sun, according to a news release about the study. Marusiak was not directly involved in the study, though she did have contact with the authors as a fellow expert in lunar seismology. “Every lunar morning when the sun hits the lander, it starts popping off,” said study coauthor Allen Husker, a research professor of geophysics at Caltech, in a statement. It’s important to note a key difference between the moon and Earth: On the lunar surface, there are no shifting tectonic plates that might cause catastrophic events.

"Over 90 percent of the excess energy on earth due to climate change is found in warmer oceans, some of it in surface oceans and some at depth." Put simply, the greenhouse gases serve to trap more heat, some of which is absorbed by the ocean," Kirtman told CNBC. In addition to the daily record on July 31, the monthly sea surface temperature for July was the hottest July on record, "by far," Copernicus said. CopernicusThese record sea surface temperatures arise from multiple factors, including the El Niño weather pattern, which is currently in effect. "These climate variations occur when sea surface temperature patterns of warming and cooling self-reinforce by changing patterns of winds and precipitation that deepen the sea surface temperature changes."

NASA and NOAA together found that last month's average global surface temperature was 2.02 degrees Fahrenheit above the 20th-century average. Last month was also the fourth consecutive month that global ocean surface temperatures hit a record high, the scientists said. This trend in ocean warming carries far-reaching consequences, he said. Changes in ocean temperatures can also have enormous impacts on marine species and their broader ecosystems, he said. This phenomenon is characterized by warm ocean surface temperatures in parts of the Pacific Ocean and tends to boost global temperatures and influence weather conditions around the world.

Astronomers discovered a distant star swallowing a planet for the first time ever. Swallowing the planet whole produced a burst of energy that expelled the star's outer layers, causing it to expand and brighten rapidly. Except for a veneer of dust, the star pretty much looked the same as it had before, one year after devouring its planet. The distant planet that just got absorbed by its star was about the size of Jupiter, which is more than 1,300 Earths. (It later turned out, this pre-eruption dust was material from the planet skimming the atmosphere of the star as it orbited closer and closer.)
