The ‘best' meteor shower of 2025 is coming TONIGHT as Earth passes through field of fireballs linked to ancient comet

The Suna day ago
STARGAZERS are preparing for one of the best meteor showers in the astronomical calendar with up to 150 fireballs shooting through the sky an hour.
Experts at the European Space Agency say the display is so good it will appear as though "natural fireworks will fill the sky".

The popular Perseids meteor shower is expected to peak tonight as Earth passes through debris from an ancient comet.
It's been active since mid-July and will tail off after Tuesday's peak, ending on August 24.
Best of all, you should be able to see shooting stars without any equipment needed.
However, scientists have warned that the brightness of the full Moon may obscure the view.
"It is one the fastest and brightest meteor showers of the year, so an astronomical highlight for stargazers," explained Dr Shyam Balaji, theoretical physicist at King's College London.
"The best place to view the Perseid meteor shower is in the North East near the constellation Perseus.
"While you can look at the whole sky and are likely to see a meteor, that's the target location in order to get the best viewing experience."
The meteor is a visual treat that comes back year after year thanks to a comet called Swift-Tuttle.
Swift-Tuttle is estimated to be more than 5billion years-old, older than Earth.
Debris left from it falls through the Earth 's atmosphere, burning up to create a magnificent meteor shower display.

If you're lucky you might even spot Jupiter and Venus amid the meteor shower too, as they're due to appear at their closest.
"For me personally, the best way to view the meteor shower is just with your naked eye because of the speed with which they move," Dr Balaji added.
"But you could use Sky Guide or Stellarium or other stargazing apps to get a better viewing experience, to target the right regions of the sky to see the meteor shower."
TIPS FOR WATCHING METEOR SHOWERS
Avoid light pollution - Stargazers should head to a location well away the city lights, the glow of a town, and even that of street lamps
Put the phone away - You should give your eyes at least 15 minutes to adjust to the dark so you can see the fainter meteors
Unobstructed view - Make sure that your star gazing spot has an unobstructed view of the horizon and above, away from treelines or cityscapes is best
What's the difference between an asteroid, meteor and comet?
Here's what you need to know, according to Nasa...
Asteroid: An asteroid is a small rocky body that orbits the Sun. Most are found in the asteroid belt (between Mars and Jupiter) but they can be found anywhere (including in a path that can impact Earth)
Meteoroid: When two asteroids hit each other, the small chunks that break off are called meteoroids
Meteor: If a meteoroid enters the Earth's atmosphere, it begins to vapourise and then becomes a meteor. On Earth, it'll look like a streak of light in the sky, because the rock is burning up
Meteorite: If a meteoroid doesn't vapourise completely and survives the trip through Earth's atmosphere, it can land on the Earth. At that point, it becomes a meteorite
Comet: Like asteroids, a comet orbits the Sun. However rather than being made mostly of rock, a comet contains lots of ice and gas, which can result in amazing tails forming behind them (thanks to the ice and dust vaporizing)

Ethiopian fossils reveal new species in human evolutionary lineage

Aug 13 (Reuters) - Researchers have unearthed tooth fossils in Ethiopia dating to about 2.65 million years ago of a previously unknown species in the human evolutionary lineage, one that lived in the same time and place as the earliest-known member of the genus Homo to which our own species belongs. The scientists discovered in the Ledi-Geraru research project area of northeastern Ethiopia's Afar Region 10 teeth - six molars, two incisors, one premolar and one canine - that they concluded belonged to a new Australopithecus species. The teeth came from two individuals. Until now, six species of the genus Australopithecus, an important early human ancestor that displayed a mix of ape-like and human-like traits, were known from fossils at various African sites. The researchers said the newly found teeth bore traits indicating they belonged to a seventh species. A genus is a group of closely related species that share similar characteristics. For example, lions and tigers are from the same genus but represent different species. The scientists also discovered three other teeth dating to 2.59 million years ago that had traits showing they belonged to the oldest-known species of Homo, one that was first revealed by a jawbone unearthed in the same vicinity in 2013. Scientists have not yet assigned names to the Australopithecus and Homo species represented by these 13 teeth because of the incomplete nature of the fossil remains. Our species Homo sapiens is the most recent member of the Homo genus, first appearing roughly 300,000 years ago in Africa before later spreading worldwide. The new dental fossils provide insight into a poorly understood period in human evolution. The close age of the teeth suggests that this newly identified Australopithecus species coexisted in this region with the early Homo species, raising questions about whether they competed for the same resources. The teeth also indicate that there were four hominins - as species in the human evolutionary lineage are known - that inhabited East Africa at the time. Previous fossils showed that another Australopithecus species and a species of Paranthropus, a hominin possessing a specialized skull adapted for heavy chewing, lived in East Africa during this time. An additional Australopithecus species also inhabited southern Africa, bringing the number of hominins then on the continent to five. The presence of these contemporaneous hominins illustrates the complicated nature of the human evolutionary process. "This reinforces the idea that the story of human evolution is not of a single lineage changing slowly through time," said University of Nevada, Las Vegas paleoanthropologist Brian Villmoare, lead author of the research published on Wednesday in the journal Nature, opens new tab. "Rather, the pattern of human evolution is similar to that of other organisms, repeatedly branching into multiple species throughout the fossil record, many of whom lived at the same time," Villmoare added. The researchers are seeking clues about the nature of any interaction between the Australopithecus and Homo species represented by the 13 teeth. "We are currently analyzing teeth to see if we can tell if they ate the same thing," said Arizona State University paleoecologist and project co-director Kaye Reed. If so, they may have fought over resources, Reed said. Crude stone tools dating to about the same time were previously discovered nearby, Reed said, probably made by the Homo species. The researchers determined the age of the teeth using a technique that dated feldspar crystals contained in volcanic ash in the sediments where they were discovered based on radioactive decay of the element argon. The Afar Region, one of Earth's hottest and lowest places, is an arid expanse of badlands. But at the time of these species, rivers flowed across a vegetated landscape into shallow lakes in a landscape populated by a splendid array of animals. These included giraffes, horses, pigs, elephants, hippos and antelopes as well as predators such as saber-toothed cats and hyenas. Homo is generally thought to have descended from a species of Australopithecus, though the exact species and the timing have been a matter of debate. Australopithecus eventually died out. Australopithecus includes the famous fossil Lucy, who was a member of the species Australopithecus afarensis who lived approximately 3.18 million years ago. Lucy's remains were discovered in 1974, also in the Afar Region. The newly discovered teeth had characteristics that showed they did not belong to Lucy's species, the researchers said. "This new Australopithecus species is in no way some 'missing link,' and we actually don't think that it was necessarily ancestral to any known species," Villmoare said. "Species arose and many went extinct," Reed said. "Each find is a piece of the puzzle that puts human evolution into a twiggy tree, rather than a linear graphic."

Scientists want to send tiny, solar-powered spacecraft to Mars

Scientists want to send tiny, solar-powered spacecraft to examine difficult-to-reach parts of Earth 's atmosphere – and eventually other planets too. The small devices are able to float in the air and could carry sensing instruments to monitor our climate as well as explore Mars, the researchers behind them suggest. Unlike conventional spacecraft, they do not need fuel to stay floating in the atmosphere. Instead, they use energy from light, through a process known as photophoresis that has been used to make objects levitate for 150 years. Despite that long history, the practical use of photophoresis has been limited to truly tiny objects or very powerful artificial light, and practical devices have not worked out. Now, however, researchers believe that they have made a centimetre-long flying device out of perforated sheets that can use natural sunlight to stay afloat. The flying structure is made from two thin, perforated membranes that are attached together by tiny supports. They can be used to create a tiny disc that is then able to leveitate. They could be sent up to the upper layers of the Earth's atmosphere. If they can be scaled up slightly, they would be able to carry antennae and circuits that would allow them to be used to monitor the atmosphere and for other science work. Eventually, the same design could be taken to other planets, they suggest. It is currently almost prohibitively expensive to send satellites to Mars, for instance – but doing so with the tiny spacecraft could allow researchers to monitor conditions on that planet, they say. 'If the full potential of this technology can be realized, swarms or arrays of such photophoretic flyers could be collecting high-resolution data on the temperature, pressure, chemical composition and wind dynamics of the mesosphere within the next decade,' Igor Bargatin from Penn University wrote in an article accompanying the new research.

AI could soon detect early voice box cancer from the sound of your voice

AI could soon be able to tell whether patients have cancer of the voice box using just a voice note, according to new research. Scientists recorded the voices of men with and without abormalities in their vocal folds - which can be an early sign of laryngeal cancer - and found differences in vocal qualities including pitch, volume, and clarity. They now say AI could be used to detect these 'vocal biomarkers', leading to earlier, less invasive diagnosis. Researchers at Oregon Health and Science University believe voice notes could now be used to train an AI tool that recognises vocal fold lesions. Using 12,523 voice recordings from 306 participants across North America, they found distinctive vocal differences in men suffering from laryngeal cancer, men with vocal fold lesions, and men with healthy vocal folds. However, researchers said similar hallmark differences were not detected in women. They are now hoping to collect more recordings of people with and without the distinctive vocal fold lesions to create a bigger dataset for tools to work from. In the UK, there are more than 2,000 new cases of laryngeal cancer each year. Symptoms can include a change in your voice, such as sounding hoarse, a high-pitched wheezing noise when you breathe, and a long-lasting cough. 'Here we show that with this dataset we could use vocal biomarkers to distinguish voices from patients with vocal fold lesions from those without such lesions,' said Dr Phillip Jenkins, the study's corresponding author said. 'To move from this study to an AI tool that recognises vocal fold lesions, we would train models using an even larger dataset of voice recordings, labeled by professionals. We then need to test the system to make sure it works equally well for women and men. 'Voice-based health tools are already being piloted. Building on our findings, I estimate that with larger datasets and clinical validation, similar tools to detect vocal fold lesions might enter pilot testing in the next couple of years," he predicted. It comes after research from US-based Klick Labs, which created an AI model capable of distinguishing whether a person has Type 2 diabetes from six to 10 seconds of voice audio. The study involved analysing 18,000 recordings in order to identify acoustic features that differentiated non diabetics from diabetics and reported an 89 per cent accuracy rating for women and 86 per cent for men. Jaycee Kaufman, a research scientist at Klick Labs, praised the future potential for AI-powered voice tools in healthcare, saying: 'Current methods of detection can require a lot of time, travel and cost. Voice technology has the potential to remove these barriers entirely.'
