Longest day of the 2025 nears. What to know ahead of summer solstice.

Yahoo3 days ago

Things are getting hot across the country, and summer has not even officially begun.
The summer solstice will occur on Friday, June 20, and it will be both the longest day and shortest night of 2025 in the Northern Hemisphere, according to the National Weather Service (NWS).
The summer solstice also marks the start of the Pagan holiday, Litha, also known as Midsummer, according to the Boston Public Library. The holiday celebrates the beginning of summer and is celebrated with hilltop bonfires and dancing.
With the summer solstice near, here is everything people need to know about the grand occasion.
The summer solstice will take place on Friday, June 20, at 10:42 p.m. ET, according to Space.com.
The summer solstice marks the beginning of summer in the Northern Hemisphere. Meanwhile, the Southern Hemisphere will greet winter with its winter solstice.
"The Northern Hemisphere's tilt toward the Sun is greatest on this day," according to NASA. "This means the Sun travels its longest, highest arc across the sky all year for those north of the equator."
During the summer solstice, the tilt brings the Earth's northernmost point closer to the sun, resulting in more sunlight. The solstice itself only lasts moments, according to the Old Farmer's Almanac.
The date of the summer solstice can fall at any point between June 20 and June 22, depending on the year, according to the NWS.
In 2024, the solstice fell on Thursday, June 20.
Several locations around the world are particularly known for celebrating the solstice, including Newgrange in Ireland. Solstices are often associated with pagan religions and draw revelers of different faiths.
One of the most famous solstice celebrations takes place at the ancient Stonehenge ruins in Wiltshire, England, where many gather to herald the season.
Pagans come by the thousands to Stonehenge, the prehistoric ruins of a monument built between approximately 3100 and 1600 BC. It is one of the most famous landmarks in the UK, but little is known about the civilization that built it or why, as these ancient peoples left no written records behind.
Many theories exist as to the original purpose of Stonehenge, including the following:
A burial site
An astronomical observatory
A religious or worship site
A sort of gesture or symbol
A place of ritual or healing
Regardless, it has been the subject of many myths, stories and folklore.
It was during the 20th century that Stonehenge became a site of religious significance to people who subscribed to New Age beliefs, including Neopaganism and Neo-Druids, according to USA TODAY's previous reporting. When constructed, the stone circle was aligned with the sun, and to this day, thousands of people gather to witness the moment the sun peeks perfectly through its pillars.

Latest Starship Explosion Drastically Decreases SpaceX's Chances of Reaching Mars Without Having to Wait Years

With tech billionaire Elon Musk out of the White House after his disastrous turn as a bureaucrat, he can now focus on more pressing subjects — such as his SpaceX Starship rockets that keep on exploding into fiery columns of fire, with the latest dramatic failure this past Wednesday in Texas, when the massive spacecraft hadn't even left the ground yet. This recent setback ratchets up the pressure on Musk even further, who faces a hard deadline and steep technical challenges in his vaunted goal to reach Mars. Much of that deadline is self-imposed, as CNN points out in an excoriating new breakdown of the situation. In May, Musk said he plans to send an unmanned crew to Mars next year, but the latest blast — the latest in a string of similar explosions that have plagued Starship — seem almost certain to set him back enough to force SpaceX to miss a crucial celestial launch opportunity called a transfer window. Depending on the position of Earth and Mars from one another, the distance between the two planets can vary from 35 million to over 200 million miles. To make the journey shorter and to save cost on fuel, explorers must time their rocket launch during the transfer window, a period when Mars and Earth are in an optimal alignment that minimizes the journey's length. The next transfer window for Mars is in late 2026 and will only last for a few weeks; miss it, and the journey will be way more expensive and far longer to be practical. To still make the deadline, Musk faces the extraordinary challenge of fixing any technical challenges with Starship and present an upgraded version of the vehicle and the Super Heavy rocket booster in time before the Mars transfer window next year. In addition, SpaceX has to figure out how to fuel Starship, which needs to be topped off with propellant in orbit before making its journey to the red planet. This would involve launching numerous Starships into space and using them to fuel up the one headed to the Red Planet — a process that will pose a spectacular logistical challenge of its own. "We've never done that," Bruce Jakosky, professor emeritus of geological sciences at the University of Colorado Boulder, told CNN. "Nobody's done that — transferring fuel from one spacecraft to another in orbit autonomously." Another technical challenge SpaceX needs to solve is Starship's heat shield, which has to survive entry into Mar's atmosphere and the journey back to Earth. Back in May, Musk himself conceded that it posed "one of the toughest problems to solve." And all that is without getting into the technical feasibility of human flight to Mars, including how to shield any crew from cosmic radiation. Before any of that, of course, Starship needs to stop exploding. More on SpaceX: Elon's Explosion at Trump Appears to Have Cost Him a HUGE Deal

Thanks to bans and fees, there are fewer plastic bags littering beaches

It turns out eliminating the 'paper or plastic' question through plastic bag regulation is effectively reducing the number of bags found in shoreline litter across the United States. A new analysis of shoreline cleanup data finds that areas with plastic bag bans or consumer fees have fewer bags turning up in their litter. The research offers some of the strongest evidence yet that regulating plastic bag use makes a difference in reducing the amount of plastic waste in marine ecosystems. A heightened threat to marine wildlife 'We find, largely, that all the regulations do show a decrease in plastic bag litter as a share of total litter on these shores,' says Kimberly Oremus, co-author of the research paper and an assistant professor of marine science and policy at the University of Delaware. The total reduction ranged between 25% and 47%, the study found. About 20 metric tons of plastic end up in the environment each year, estimates the International Union for Conservation of Nature—that amounts to over 2.4 kilograms of plastic for each person on Earth. Plastic bags are particularly prevalent in marine ecosystems. They are very difficult to recycle and, because they are lightweight and have a large surface area for wind to catch, they blow out of the trash and into the environment at higher rates than other plastic items, says Erin Murphy, the ocean plastics science and research manager at the environmental advocacy nonprofit Ocean Conservancy, who was not involved in the research. She added that in 2024 alone, the conservancy's International Coastal Cleanup volunteers gathered up more than a million plastic bags. In addition to getting into the environment at high rates, plastic bags also pose a heightened threat to marine wildlife. Wildlife can become entangled in or smothered by these bags or can mistake them for food, like jellyfish, a favorite among many species. These interactions with plastic can lead to the deaths of endangered and common animals alike and can even contribute to broader population declines. Counting the plastic bags 'One big challenge in studying the effects and regulations of plastics is actually measuring this pollutant in the environment,' says Anna Papp, co-author of the research paper. To overcome this challenge, the study used crowd-funded data from beach cleanups. The data was collected by the Ocean Conservancy as part of their Trash Information and Data for Education and Solutions (TIDES) project. Nearly 19 million people have participated in the data collection worldwide. The study also examined plastic bag policies at various geographical scales between 2017 and 2023. The earliest plastic bag policies in the U.S. were implemented around 2007, researchers say, but an uptick in the mid-2010s more directly led to the policies analyzed in the study. While the data provides insight into how the share of plastic bags found among shoreline litter has changed due to policy measures, an important caveat remains: Plastic litter has been increasing overall. Plastic production doubled from 234 million to 460 million tons between 2000 and 2019—and without mitigation, it is only expected to rise, according to a recent report from the French-based Organisation for Economic Co-operation and Development (OECD). Some regulations are better than others Still, the researchers noted that not all regulations worked equally well. Total bans and consumer fees resulted in greater decreases than partial bans, which still allow businesses to use thicker, potentially reusable plastic bags. The researchers also found that regulation was most effective in places that had a high baseline of plastic bag litter before the bans or fees went into place. The study data seems to indicate that consumer fees were the most effective option for mitigating plastic bag litter, though the paper's authors say more research is needed to confirm this finding. 'These policies are effective, but they're not a panacea for all plastic litter,' Oremus said. 'Anyone who's looking at regulations for plastic broadly needs to think beyond just the consumption side of plastic.'

Neuroscientists find brain cells that explain why stress keeps you up at night

If your anxiety before a big test or a high-stakes presentation has ever kept you up at night, you can rest easier knowing that scientists are trying to get to the bottom of things. A new study published this month in The Journal of Neuroscience explores how stress interferes with sleep, causing cascading negative effects on memory and other cognitive processes. By pinpointing the specific neural mechanisms involved in stress-related memory problems and sleep disruptions, scientists hope to figure out stress-zapping treatments in the future. A group of researchers from the University of Pennsylvania School of Medicine's Chronobiology and Sleep Institute simulated human stress in lab mice, restraining the animals so they couldn't move. They then observed the animals' neural activity while they slept and gave the mice a spatial memory test. Much like a human stressed out before a big test, the mice slept poorly and showed memory deficits. The researchers went on to simulate the effects of the stress scenario without actually restraining the mice. By activating neurons that release the stress hormone corticotropin in a specific part of the hypothalamus known as the paraventricular nucleus, the research team stressed the mice out and went on to observe the same sleep and memory issues as if the animals had actually been restrained. When they blocked the same stress hormone-releasing neurons during the stress-inducing event, the mice slept a little better and had significantly less trouble during their spatial memory test – a hopeful finding understanding how to mitigate the problems that stress creates in the human brain. The researchers called the findings on the pathways of corticotropin-releasing hormone neurons in that region of the hypothalamus 'an important step toward improving sleep and ameliorating cognitive deficits associated with stress-related disorders' – a conclusion that anyone tired of having that one same stress dream can definitely get behind.
