A huge bubble of galaxies that is one billion lightyears across could be a remnant of the ripples caused by the Big Bang, according to astronomers who have mapped the structure. The structure, named Hoʻoleilana by University of Hawaii scientists, is thought to have been caused by so-called Baryon Acoustic Oscillations (BAOs). These were ripples in the particles of the early Universe in the period following the Big Bang, when planets, solar systems and galaxies were not yet fully formed. As the ripples went outward, they created areas of density in the particles, causing bubble-like structures in which galaxies eventually coalesced. Until now, the BAOs were just a prediction – part of the wider Big Bang theory. No specific structures in the Universe had been found which mimicked their patterns. But Hoʻoleilana fits the description of these huge cosmic bubbles perfectly, according to Brent Tully, who led the study at the University of Hawaii’s Institute for Astronomy. “We were not looking for it. It is so huge that it spills to the edges of the sector of the sky that we were analyzing,” he said. “As an enhancement in the density of galaxies it is a much stronger feature than expected. The very large diameter of 1bn light years is beyond theoretical expectations. “If its formation and evolution are in accordance with theory, this BAO is closer than anticipated, implying a high value for the expansion rate of the universe.” The bubble is absolutely huge. It is made up of several superclusters, structures which themselves are thought to be among the Universe’s largest arrangements of matter. This includes the Hercules Supercluster, the Corona Borealis Supercluster and the Sloan Great Wall. All of these structures contain thousands of galaxies. In the middle of Hoʻoleilana sits the Bootes Supercluster and the Bootes Void, an immense space of nothingness which is an incredible 330m lightyears across. Daniel Pomarede, from the CEA Paris-Saclay University, who contributed to the research, said: “It was an amazing process to construct this map and see how the giant shell structure of Ho’oleilana is composed of elements that were identified in the past as being themselves some of the largest structures of the universe.” The research was published on 5 September in The Astrophysical Journal.

NEW YORK--(BUSINESS WIRE)--Sep 7, 2023--

We’ve been hit with a September heatwave and, for runners – whether beginner or seasoned – it means added concerns around dehydration, chafing and generally keeping safe in the heat. Ultramarathon runner Leon Bustin, 36, completed a 220km run through the Wadi Rum desert in Jordan in October 2022, so he knows a thing or two about dealing with hot weather while exercising. Here is the athlete’s advice for heatwave running right now. Be sun safe “Covering your skin to avoid too much direct sunlight will really help,” says Bustin, who is also a content creator for Lean Machines and a personal trainer. “I highly recommend using a good zinc stick under the eyes and across the nose as well. “I used a bright purple one in the desert to remind me of my daughter and also to show very clearly if there was a part I’d missed. [Use] a higher factor than you think you need.” Hydration starts before a run “Working on your hydration starts before you take a single step out of the door,” he says. “I even start my day with an electrolyte-rich glass of water as we even become dehydrated in our sleep. “So having a good 500ml of electrolyte-rich water pre-run will really help, then as a good basic guideline take a further 500ml for each hour you are out. “The important thing is adding the electrolytes to the water. If we over-consume [pure water] we may dilute and flush out essential electrolytes and trace minerals as we pee.” Cool bare skin “Try cooling the glabrous – or none hairy- areas, it really helps flush heat out of your body fast,” says Bustin. “Those areas include the palms of your hands, under eyes, ears and soles of your feet. “Every time l arrived at an aid station in the desert l would hand over my water bottles to be refilled and plunge my hands straight into a bucket of coldish water, splash my face then keep the hands there for a good 30 to 40 seconds.” For those of us without air stations, Bustin suggests wetting exposed skin with water from a bottle. Pop a flannel in the freezer before going on a run and run it across your skin afterwards, or midway. “The key to keeping cool on a run is managing your core temperature because if that rises too much, put simply, it will be the end of your race,” he adds. Breath correctly “Breathing right for you is really important to get nailed down regardless of the running conditions, but especially in the heat as we don’t want to put any unnecessary extra stress on our bodies – because it will just cost more energy,” says Bustin. “We all tend to over-breathe through our mouth so simply focusing more of our inward breaths to be through the nose will help more than you think and over time both bring down and regulate your average heart rate greatly.” Be careful of the chafe Chafing can put you off pretty early in your running journey, and in the heat, where shorts can leave thighs rubbing together and slick with sweat, it’s a run-ruiner. “Anti-chafe cream is your best friend in the key areas (between the thighs and under the arms),” says Bustin, “but also if you get lots of toe blisters like me. “I put a generous dose between my toes of a good oil-based anti-chafe or even just some good old Sudocrem to keep those toes gliding. The right cream for you will take trial and error and is also combined with wearing the right run kit for you as well.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Women being invited to help shape the future of reproductive healthcare – from period pain to menopause How to style your home like a professional One in 10 ‘spending beyond their means’ – try these 7 cutbacks guaranteed to save families money

India’s Vikram lunar lander has recorded movement below the surface of the Moon – but it’s probably not aliens. Experts think the movement is seismic activity – the lunar equivalent of earthquakes. It is the first time humans have detected the so-called moonquakes since the 1970s. The new activity was recorded by the Vikram lander’s onboard instrument for lunar seismic activity, a piece of kit designed “to measure ground vibrations generated by natural quakes, impacts, and artificial events,” the Indian Space Research Organization (ISRO) said. India’s Chandrayaan-3 mission saw it land the Vikram and its sister craft, the Pragyan rover, last month, becoming the first nation to land near the Moon’s little-explored South Pole. It also makes India just the fourth nation to land on the Moon, alongside the US, the former USSR and China. The seismic activity is the first recorded since the US Apollo programme, which ended in 1977. Those recordings yielded valuable data about the Moon’s makeup. Scientists have been able to theorise that the Moon has an inner core which is much less dense than the Earth’s and which is about 500km across. On Earth, seismic activity is caused by the shifting of the planet’s tectonic plates. But on the Moon, things are a bit different. The quake could be caused by thermal activity from the Sun, or by tidal stresses caused by Earth’s gravity, cracking the planet and causing the pieces to rub together. The team noted that the event is currently under investigation. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
