☆ A 'severe' geomagnetic storm is forecast for Earth for the first time in years — here's what to know about these storms
▼ + stars: | 2024-05-10 | by ( Ellyn Lapointe | ) www.businessinsider.com time to read: +4 min

Read previewFor the first time in nearly 20 years, the National Oceanic and Atmospheric Administration has forecasted a "severe" G4 geomagnetic storm to hit this Friday, dazzling states across the northern US with aurora. 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.

NOAAAnd in the last 24 hours, AR3664 spit out four coronal mass ejections that are now hurtling toward Earth at roughly 560 miles per second, Owens told BI. Even states including Maryland, New York, and Pennsylvania, could catch a glimpse of the aurora low on the horizon, Young told BI. The reality is that we just won't know how bright, active, and wide-reaching the aurora will be until the coronal mass ejections reach Earth's atmosphere. The most extreme estimate of aurora and where they can be seen in the US came from Alex Young.

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.

The ocean has now broken temperature records every day for more than a year. And so far, 2024 has continued 2023’s trend of beating previous records by wide margins. In fact, the whole planet has been hot for months, according to many different data sets. “There’s no ambiguity about the data,” said Gavin Schmidt, a climatologist and the director of the NASA Goddard Institute for Space Studies. “So really, it’s a question of attribution.”Understanding what specific physical processes are behind these temperature records will help scientists improve their climate models and better predict temperatures in the future.

☆ Someday, Earth Will Have a Final Total Solar Eclipse
▼ + stars: | 2024-04-09 | by ( Katherine Kornei | ) www.nytimes.com time to read: 1 min

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.

CNN —Peach trees are blooming at Jaemor Farms in Alto, Georgia, this week. Owner Drew Echols, a fifth-generation farmer, said it has become harder to predict when fruits like the iconic Georgia peaches would start blooming. Blooming peach trees are seen alongside a covered field of strawberries at Jaemor Farms in Alto, Georgia, on March 19, 2024. The fruits begin to bloom as temperatures warm, but when a cold spell comes back, they become susceptible to damage. Fruits like peaches, strawberries, mangoes and plums typically reach their peak ripeness during the summer months.

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
▼ + stars: | 2023-11-01 | by ( Seth Borenstein | Associated Press | ) www.businessinsider.com time to read: +3 min

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.

"We anticipate growing threats to this burgeoning sector of the U.S. economy," a U.S. counterintelligence official told Reuters, adding that "China and Russia are among the leading foreign intelligence threats to the U.S. space industry." The document warned companies to be on guard for facility visit requests, and attempts to gather confidential information at conferences. U.S. authorities have for years said Chinese hackers are targeting U.S. space know-how, including having accessed computers at the NASA Goddard Space Center and Jet Propulsion Laboratory, as well as numerous companies involved in aviation, space and satellite technology. China says its space program is for peaceful purposes, but U.S. military officials say Beijing sees space as crucial to its military strategy. The U.S. warned this year that China seeks to match or surpass it as a leader in space by 2045.

☆ Oceans absorb 90% of the heat from climate change — here's why record ocean temps are so harmful
▼ + stars: | 2023-08-16 | by ( Catherine Clifford | In Catclifford | ) www.cnbc.com time to read: +22 min

"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.

Climate change, caused by burning fossil fuels, is unequivocally warming the Earth’s temperature, NASA scientists said. “It’s really only just emerged, and so what we’re seeing is not really due to that El Niño,” Schmidt told reporters. But, he added, it is likely that a sweltering 2024 will exceed it, precisely because of El Niño’s influence. “We anticipate that 2024 is going to be an even warmer year because we’re going to be starting off with that El Niño event,” Schmidt said. “This issue with ocean temperature is not a problem that stays in the ocean – it affects everything else.” Castillo noted hotter ocean temperatures can make hurricanes stronger and make ocean levels rice due to glacial melt.

The NSF funded the 15-year experiment, which is called the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). Supermassive black holes are thought to exist at the center of every galaxy. Her lab runs computer models of merging supermassive black holes to predict how they behave and what signals they send out into space.

El Niño is the warm phase of the El Niño La Niña Southern Oscillation, or ENSO, that occurs across the tropical Pacific Ocean roughly every five years. El Niño generally causes drier conditions in Australia and Southeast Asia, and wetter and warmer conditions in the Americas. El Niño ("little boy" in Spanish) and La Niña ("little girl" in Spanish) are weather patterns in the Pacific Ocean that can impact weather conditions around the globe. NOAA said there is an 84% chance of an El Niño with a greater than moderate strength and a 56% chance of a strong El Niño developing by the winter. While these regions may see warmer temperatures, Schmidt was careful to point out that El Niño does not guarantee a heat record in any region.

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.)

“We need to have tabletop exercises that go through a variety of scenarios, including possibly nuclear weapons,” a senior official told CNN earlier this month.
