When is the first day of summer? When's the summer solstice? How much daylight will Ohio see?
Summer is on its way. That means hotter temperatures, family vacations, and maybe a trip to Cedar Point or Kings Island.
When is the first day of summer 2025? When is the summer solstice? Here's what to know.
The first day of summer can vary, depending on the context.
Climate scientists often identify June 1 as the first day of the meteorological summer. But if you're looking at the astronomical calendar, summer starts a few weeks later. The astronomical season begins with the summer solstice on June 20, 2025, according to the Old Farmer's Almanac.
In Ohio and the rest of the Eastern time zone, the summer solstice will happen at 10:42 p.m. ET, according to Space.com. The site states that daylight in temperate and mid-northern latitudes, such as Ohio, could last 15 hours that day.
The summer solstice marks the beginning of the summer astronomical season.
June 20 will be the day of the year when we will enjoy the longest hours of daylight in the northern hemisphere. After this day, the daylight hours will begin to shorten as summer progresses.
According to the National Centers for Environmental Information, astronomical seasons are defined by the Earth's orbiting position in relation to the sun, Meteorological seasons are dictated by the Earth's temperatures, per USA Today.
The Earth's tilt and "the sun's alignment over the equator" shape the equinoxes and solstices. The Earth is tilted approximately 23.5 degrees on its axis. Because of this tilt, there are times when part of our planet leans toward the sun, and other times when another part of the planet faces away, according to NCEI.
The Earth's elliptical orbit brings our planet closer or farther to the sun, depending on where the planet is in its 365.24-day cycle. These factors determine when the astronomical seasons fall, and each season varies in length from 89 to 93 days. And because of these variations in length, meteorological seasons were created.
So basically, meteorological summer begins on June 1, and astronomical summer 2025 starts with the summer solstice on June 20.

Ryan Gosling's Latest Appearance Is a 180 From His Wild Sci‑Fi Transformation
Ryan Gosling's Latest Appearance Is a 180 From His Wild Sci‑Fi Transformation originally appeared on Parade. Ryan Gosling is ditching his wild beard and long locks from the sci-fi transformation he debuted earlier this summer. Over the weekend, the 44-year-old actor stopped by San Diego Comic-Con where he appeared on a panel to discuss his upcoming film, Project Hail Mary. While Gosling was on hand to discuss his on screen journey to space, he looked nothing like his character. In the trailer, which premiered in June, Gosling was almost unrecognizable with a bushy beard and unwashed, stringy hair — and at Comic-Con, Gosling was back to his usual, well-kept self. He was joined by the film's directors Phil Lord and Christopher Miller as well as screenwriter Drew Goddard and author Andy Weir, who penned The Martian, the novel that inspired the film. 🎬 SIGN UP for Parade's Daily newsletter to get the latest pop culture news & celebrity interviews delivered right to your inbox 🎬 The movie is set to follow middle school teacher Ryland Grace who is tasked with traveling to space, 11.9 light-years away, in order to figure out why the sun is dying and save Earth from extinction. In the midst of his endeavor, Grace wakes up on a spaceship, confused about why he is there and lacking any recollection of his past. Although the teacher attempts to bow out of the massive responsibility, he quickly learns that he doesn't have a choice in the matter. While discussing his physical transformation for the role at the event, Gosling jokingly referred to his character as "a space caveman, in this placenta onesie" — noting that he hopes to see the placenta onesie at Comic-Con in the future. Gosling added that he and the writers "tried to create these different layers to him as he's evolving from a space caveman to a space person that needs to do some really important stuff." "What's so inspiring about him is he reacts to a lot of things like I might or a lot of us might, and he's terrified appropriately of the task at hand," Gosling said, per PEOPLE. "He's somebody who on Earth had given up on himself, and has been given this opportunity to believe in himself again." Project Hail Mary is set to premiere March 20, 2026. Watch the Project Hail Mary trailer below.

Millions of people are suffering from brain fog. A new study will find out why
Millions of people who recover from infections like COVID-19, influenza and glandular fever are affected by long-lasting symptoms. These include chronic fatigue, brain fog, exercise intolerance, dizziness, muscle or joint pain and gut problems. And many of these symptoms worsen after exercise, a phenomenon known as post-exertional malaise. Medically the symptoms are known as myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS). The World Health Organization classifies this as a post viral fatigue syndrome, and it is recognised by both the WHO and the United States Centers for Disease Control and Prevention as a brain disorder. Experiencing illness long after contracting an infection is not new, as patients have reported these symptoms for decades. But COVID-19 has amplified the problem worldwide. Nearly half of people with ongoing post-COVID symptoms – a condition known as long-COVID – now meet the criteria for ME/CFS. Since the start of the pandemic in 2020, it is estimated that more than 400 million people have developed long-COVID. To date, no widely accepted and testable mechanism has fully explained the biological processes underlying long-COVID and ME/CFS. Our work offers a new perspective that may help close this gap. Our research group studies blood and the cardiovascular system in inflammatory diseases, as well as post-viral conditions. We focus on coagulation, inflammation and endothelial cells. Endothelial cells make up the inner layer of blood vessels and serve many important functions, like regulating blood clotting, blood vessel dilation and constriction, and inflammation. Our latest review aims to explain how ME/CFS and long-COVID start and progress, and how symptoms show up in the body and its systems. By pinpointing and explaining the underlying disease mechanisms, we can pave the way for better clinical tools to diagnose and treat people living with ME/CFS and long-COVID. What is endothelial senescence? In our review, our international team proposes that certain viruses drive endothelial cells into a half-alive, 'zombie-like' state called cellular senescence. Senescent endothelial cells stop dividing, but continue to release molecules that awaken and confuse the immune system. This prompts the blood to form clots and, at the same time, prevent clot breakdown, which could lead to the constriction of blood vessels and limited blood flow. By placing 'zombie' blood-vessel cells at the centre of these post-viral diseases, our hypothesis weaves together microclots, oxygen debt (the extra oxygen your body needs after strenuous exercise to restore balance), brain-fog, dizziness, gut leakiness (a digestive condition where the intestinal lining allows toxins into the bloodstream) and immune dysfunction into a single, testable narrative. From acute viral infection to 'zombie' vessels Viruses like SARS-CoV-2, Epstein–Barr virus, HHV-6, influenza A, and enteroviruses (a group of viruses that cause a number of infectious illnesses which are usually mild) can all infect endothelial cells. They enable a direct attack on the cells that line the inside of blood vessels. Some of these viruses have been shown to trigger endothelial senescence. Multiple studies show that SARS-CoV-2 (the virus which causes COVID-19 disease) has the ability to induce senescence in a variety of cell types, including endothelial cells. Viral proteins from SARS-CoV-2, for example, sabotage DNA-repair pathways and push the host cell towards a senescent state, while senescent cells in turn become even more susceptible to viral entry. This reciprocity helps explain why different pathogens can result in the same chronic illness. Influenza A, too, has shown the ability to drive endothelial cells into a senescent, zombie-like state. What we think is happening We propose that when blood-vessel cells turn into 'zombies', they pump out substances that make blood thicker and prone to forming tiny clots. These clots slow down circulation, so less oxygen reaches muscles and organs. This is one reason people feel drained. During exercise, the problem worsens. Instead of the vessels relaxing to allow adequate bloodflow, they tighten further. This means that muscles are starved of oxygen and patients experience a crash the day after exercise. In the brain, the same faulty cells let blood flow drop and leak, bringing on brain fog and dizziness. In the gut, they weaken the lining, allowing bits of bacteria to slip into the bloodstream and trigger more inflammation. Because blood vessels reach every corner of the body, even scattered patches of these 'zombie' cells found in the blood vessels can create the mix of symptoms seen in long-COVID and ME/CFS. Immune exhaustion locks in the damage Some parts of the immune system kill senescent cells. They are natural-killer cells, macrophages and complement proteins, which are immune molecules capable of tagging and killing pathogens. But long-COVID and ME/CFS frequently have impaired natural-killer cell function, sluggish macrophages and complement dysfunction. Senescent endothelial cells may also send out a chemical signal to repel immune attack. So the 'zombie cells' actively evade the immune system. This creates a self-sustaining loop of vascular and immune dysfunction, where senescent endothelial cells persist. In a healthy person with an optimally functioning immune system, these senescent endothelial cells will normally be cleared. But there is significant immune dysfunction in ME/CFS and long-COVID, and this may enable the 'zombie cells' to survive and the disease to progress. Where the research goes next There is a registered clinical trial in the US that is investigating senescence in long-COVID. Our consortium is testing new ways to spot signs of ageing in the cells that line our blood vessels. First, we expose healthy endothelial cells in the lab to blood from patients to see whether it pushes the cells into a senescent, or 'zombie,' state. At the same time, we are trialling non‑invasive imaging and fluorescent probes that could one day reveal these ageing cells inside the body. In selected cases, tissue biopsies may later confirm what the scans show. Together, these approaches aim to pinpoint how substances circulating in the blood drive cellular ageing and how that, in turn, fuels disease. Our aim is simple: find these ageing endothelial cells in real patients. Pinpointing them will inform the next round of clinical trials and open the door to therapies that target senescent cells directly, offering a route to healthier blood vessels and, ultimately, lighter disease loads.

The Directors of ‘Project Hail Mary' Explain Why the Movie Is a PC, Not a Mac
Making movies is all about compromises. This actor is unavailable, so you cast someone else. That location is too expensive, so let's build a set. This shot is impossible, so let's think of something better. At every step, the big, huge mechanism of filmmaking is always a work in progress. But on Project Hail Mary, directors Chris Miller and Phil Lord tried to embrace a new philosophy. 'What's great about this movie is there are so many things that make it harder to make,' Miller said in Hall H at San Diego Comic-Con. 'All of the zero G, all of the centrifugal gravity, the characters have to have a wall between them because their atmospheres are different. Everything that a regular movie would be like, 'Oh, we can change that,' we were like, 'Anything that makes it harder we're not going to change.' We're going to stay true to it, and then that difficulty is what makes it interesting and makes it special.' His co-director, Phil Lord, put it another way. 'We kept saying, with respect, this movie is not a Mac, it's a PC,' he said, to much laughter. 'The movie is a machine, the ship is a machine; it can be beautiful, it just can't be pretty.' It is true that almost everything about Project Hail Mary makes it seem incredibly difficult to make. Most of the movie is set on a spaceship. That spaceship meets an alien race represented by a creature made out of stone that doesn't speak English. Changing the setting or the character could've still conveyed the overall idea of the story, but it wouldn't be the story author Andy Weir wrote in his novel. So everything had to be right. So how did Lord and Miller bring that rock creature, nicknamed Rocky, to life? 'We called our friend Neil Scanlan at the Lucasfilm creature shop, and we tackled it together,' Miller said. 'We built a practical creature that was puppeteered by an amazing puppeteer named James Ortiz and a team of five, which we called the Rocketeers, and it was amazing having Rocky there on set every day so that we could have a real interaction and shoot the whole thing practically. Ultimately, it's going to end up being a beautiful blend of creature puppetry and animation, and he comes alive in a way that you would die for this character.' Sounds like it's beautiful, but maybe not pretty, just like a PC. Project Hail Mary, starring Ryan Gosling, opens in theaters on March 20. Want more io9 news?
