NASA discovers 26 'unknown bacterial species' that can survive in space
Scientists from NASA's Jet Propulsion Laboratory, working alongside Saudi Arabian and Indian researchers, have uncovered 26 previously undiscovered bacterial species flourishing in these ultra-clean environments. Cleanrooms are typically hostile to microbes and serve as the ultimate safeguard with strictly controlled air, temperature, and humidity levels.
The discovery of these bacteria challenges our understanding of microbial toughness and hints at organisms that might endure the harsh realities of space. These microbes, dubbed extremophiles, boast genetic features including DNA repair capabilities and immunity to radiation and toxic substances.
This suggests they could potentially survive interplanetary journeys and serve as valuable biological tools down the line, reports the Daily Star.

The research was spearheaded by scientists from the King Abdullah University of Science and Technology (KAUST) working with NASA's Jet Propulsion Laboratory and academic institutions throughout India and Saudi Arabia.
Professor Alexandre Rosado, KAUST's lead researcher on the project, explained: "We were looking for extremophiles-organisms that can survive the kinds of extremes found in space.
"And what we found were bacteria with the potential to not only hitchhike to Mars, but to help us engineer future medicines, preserve food, or clean up toxic waste right here on Earth."
Junia Schultz, the study's primary author, noted these findings "raise critical questions for planetary protection," whilst also creating fresh opportunities. She remarked: "Imagine engineering these genes into beneficial microbes for medical use or food safety. Space, it turns out, might be an untapped reservoir for biotech innovation."
Dr. Kasthuri Venkateswaran, a senior NASA scientist and co-author of the study, commented: "These tiny organisms could one day help us terraform other planets, cure diseases, or simply understand how life began and thrives in the most unexpected places."
The research is also crucial for NASA to predict the types of bacteria astronauts may encounter on space missions and to devise ways to combat microbial contamination in sterile environments.

The Daily Star previously highlighted that the quest for extraterrestrial life has spanned from lunar explorations to the farthest corners of deep space.
Yet, aliens have seemingly been hiding in plain sight, squatting inside China's Tiangong space station, a mere 280 miles above Earth.
A new type of bacteria, dubbed Niallia tiangongensis in tribute to their artificial abode, was discovered residing within a cabin on the orbiting station.
Scientists are astounded as these microscopic beings have NEVER been observed on our planet before.
Although related to a terrestrial soil bacterium, these space-dwelling variants have developed unique adaptations enabling them to survive the harsh conditions of space.

Enormous asteroid bigger than a 15-story building headed toward Earth in just DAYS
An asteroid the size of the Leaning Tower of Pisa has been spotted just days before it screams past Earth in the latest near-miss astronomers have tracked. NASA has announced that asteroid 2025 OW is expected to pass within 393,000 miles of Earth on Monday, July 28. It's actually one of five asteroids NASA's Jet Propulsion Laboratory (JPL) making a close pass by Earth over the next week. Two other asteroids, both between 100 and 200 feet long, are projected to miss Earth by more than a million miles on Thursday. Another small asteroid is expected to pass our planet on Saturday. However, 2025 OW is the largest of this ominous group and will also come much closer to striking the planet on Monday. The space rock has been measured to be approximately 210 feet long, making it comparable to a 15-story building or a large airplane. Its projected distance of 393,000 miles would put it just beyond the moon, which orbits Earth 239,000 miles away. While NASA has said that 2025 OW poses no risk at this time, they noted asteroids of this size could cause minor structural damage or shatter windows if it were to enter the atmosphere over a populated area. Astronomers categorize 2025 OW as a small to medium-sized asteroid, meaning it's not a 'planet-killer' which would cause an extinction-level event on Earth. This type of asteroid generally explodes in the atmosphere and doesn't reach the Earth's surface due to the intense frictional heating and pressure placed on the rock as it enters at high speeds. Scientists said 2025 OW is traveling at about 47,000 miles per hour, which is about an average speed for a near-Earth asteroid (NEA). For comparison, the 500-foot asteroid 2024 MK was traveling at roughly 34,000 mph when it came within 184,000 miles of Earth last July. Meanwhile, the worryingly large, 1,100-foot 99942 Apophis is traveling at 67,000 mph and is expected to come within 20,000 miles of Earth on April 13, 2029. At just 210 feet in length, it won't be visible with the naked eye or through binoculars when it reaches its closest point from the Earth. When it comes to tracking potentially dangerous asteroids, NASA's calculations are typically right on the money, meaning a major error that brings 2025 OW on a collision course with us unlikely. NASA JPL's Center for Near-Earth Object Studies (CNEOS) uses ground-based telescopes and planetary radar systems like the Goldstone Solar System Radar to detect and track asteroids. These systems measure an asteroid's position, velocity, and brightness to determine its orbit and size. While NASA is staying on top of these smaller asteroids in view, scientists have recently raised alarm about dangerous objects coming at our planet from our stellar 'blind side.' A recent study warned that Venus blocks out our view of many near-Earth asteroids - large space rocks that cross or come near Earth's orbit - setting up the potential for a devastating impact no one sees coming. Researchers from Brazil, France, and Italy found that several asteroids in sync with Venus's orbit are extremely hard to spot because they're often hidden by the sun's glare. Three in particular, 2020 SB, 524522, and 2020 CL1, have orbits that take these asteroids dangerously close to Earth. The three asteroids flying along with Venus measure between 330 and 1,300 feet in diameter, making each one capable of leveling entire cities and setting off massive fires and tsunamis.

What is the world's oldest snake? Jurassic reptile found in UK
There are three snake species native to the UK - the adder, grass snake and smooth snake. But the UK is also thought to be the home of the world's oldest snake, which dates back 167 million years to the Jurassic period. Native wild animals in the UK What is the oldest snake in the world? The oldest snake in the world is the Eophis underwoodi, according to BBC Wildlife Magazine. Fossil remains of the snake, primarily jaw fragments, were found in the Forest Marble Formation at Kirtlington Quarry in Oxfordshire. Eophis underwoodi dates back around 167 million years to the Bathonian Age during the Middle Jurassic era. BBC Wildlife Magazine said: "Prior to 2015, the oldest known fossil snakes were ~100 million years old. "The discovery of Eophis extended the known geological range of snakes by more than 60 million years and suggested they may have originated at a similar time to most other major groups of scaly reptiles." The snake is believed to have been alive around the same time as the Megalosaurus - a 6-metre long, meat-eating dinosaur, which also called a similar part of southern England home. BBC Wildlife Magazine added that the Eophis was "far from a giant", only measuring around 25cm. This is a far cry from the Titanoboa, which is the largest snake ever, at around 13m in length (which dates back to around 60 million years ago). The Eophis underwoodi was much smaller than the Titanoboa (pictured), which is the largest snake ever. (Image: Getty Images/iStockphoto) The BBC experts continued: "Eophis is thought to have lived in swamps, hunting tiny fish, insects, and tadpoles. "It's also believed it had tiny hind limbs, like many other ancient snakes." RECOMMENDED READING: How long do the UK's native snakes live for? The three snakes that can currently be found in the UK have a lifespan ranging from 15 to 25 years, according to The Wildlife Trusts. The adder has an average lifespan of up to 15 years, while the smooth snake can live for around 20 years. The grass snake has the longest average lifespan of the UK's native species, as it can live for up to 25 years.

Betelguese: Scientists discover why dazzling star changes brightness
Astronomers say they have confirmed why Betelgeuse, one of the night sky's most dazzling stars, regularly changes brightness. For the first time, they have discovered a much smaller companion star that is orbiting the red to new research, this 'little buddy' has a mass around 1.5 times greater than our say its passage across Betelgeuse's face causes a 400 day cycle of dimming, as well as another one that lasts for nearly six years. What have experts discovered? Betelgeuse is more than 10,000 times brighter than our Sun, and as a result, its blinding light makes spotting anything nearby say that they long suspected that Betelgeuse might have a star nearby and are delighted with the new turned to the the Gemini North telescope in Hawaii to prove their a technique called speckle imaging, they put together many images to overcome issues that Earth's atmosphere causes telescopes that are based on the ground. Steve Howell, a NASA scientist who led the research team, said: "Previous papers that predicted Betelgeuse's companion believed that no one would likely ever be able to image it."The companion star is around four times the distance from Betelgeuse as the Earth is from the to the US research centre NOIRLab, which operates the Gemini Observatory, the discovery is the first time such a close companion star has been detected orbiting a supergiant. What is Betelgeuse? According to the International Gemini Observatory, Betelgeuse is one of the brightest stars in the night sky, and the closest red supergiant to in the constellation of Orion, people have observed Betelgeuse with the naked eye for thousands of years. It has a huge volume, and is around 1,000 times bigger than our Sun. It's thought to only be 10-million-years-old, however, due to its large mass it has evolved quickly and is late in its life.
