Thousands of pieces of space debris orbit Earth at low altitudes. Ground-based scientists meticulously calculate their trajectories to prevent collisions. Traditionally limited to just a few nighttime hours, researchers have now developed a method to track debris continuously—even in broad daylight.

In the unimaginably distant future, the explosion of a hypothetical black dwarf could signal the final chapter for our Universe. The Big Freeze represents one possible destiny for the Universe. According to established physics, star formation will cease far in the future. Galaxies will darken, black

On Sunday, a car-sized asteroid made a record-close pass just 2,950 km from Earth. Experts at NASAs Center for Near-Earth Object Studies didnt detect it until six hours after its flyby. Measuring 5.5 meters wide by 2 meters long, the space rock—now designated 2020 HQ—raced over Earths southern hemis

A small air leak on the ISS has prompted astronauts to relocate to the Russian segment for the weekend, allowing NASA to pinpoint the source. Expedition 63 crew members face no immediate danger. This minor leak was first detected in September 2019, but its low air loss rate did not pose a significan

Blue Origin, the spaceflight company founded by Jeff Bezos, has delivered a full-scale engineering model of its lunar lander to NASA. This prototype positions the company as a strong contender to ferry astronauts to the Moon by 2024 under the Artemis program.Last May, NASA awarded contracts to three

Approximately 359 million years ago, one or more nearby supernovae may have triggered the extinction of over 90% of terrestrial life, according to recent research.At the close of the Devonian period, oceans teemed with massive marine creatures, some rivaling the size of school buses. Then, a catastr

Weekend media buzz in the U.S. sparked concerns over an asteroid potentially entering Earths atmosphere on November 2, 2020—just before the presidential election. As astronomers with decades tracking near-Earth objects, heres what the data really shows.Minimal Impact RiskOn August 16, 2020, a car-si

Citizen scientists have spearheaded the discovery of 95 new brown dwarfs, most of them exceptionally cold and located just tens of light-years from our Sun.In 2018, NASA launched Backyard Worlds: Planet 9, a citizen science platform featuring hundreds of millions of infrared sky images from the WISE

Researchers at the University of Warwick have confirmed 50 exoplanets using a sophisticated machine learning algorithm, paving the way for accelerated discoveries in the future.Astronomers hunt for exoplanets using the transit method, which detects small, regular dips in a stars brightness caused by

Deinococcus bacteria have endured three years in the vacuum of space, according to researchers. This resilience suggests they could potentially survive interplanetary journeys, such as between Earth and Mars.Seeds of Life Across the UniverseThe panspermia hypothesis posits that microbes can travel b

Chinas National Space Administration (CNSA) has successfully activated key instruments on the Tianwen-1 spacecraft during its journey to Mars. The probe is also gearing up for its second trajectory correction maneuver. Launched on July 28 from Wenchang Space Launch Site, Tianwen-1 aims to orbit Mars

NASA engineers have successfully completed a pivotal test, confirming the James Webb Space Telescopes ability to receive and respond to commands in space. With this milestone, the October 2021 launch appears firmly on track. Reliable communication is essential for any space mission. Even the most ad

Recent studies suggest rogue planets could outnumber stars in our galaxy. NASAs upcoming Nancy Grace Roman Space Telescope promises to illuminate these elusive wanderers. Detecting exoplanets is a monumental challenge. These distant worlds emit no light of their own, so astronomers rely primarily on

First synthesized in 2012, aerographite earned its place as the worlds lightest solid. Its ultra-low density and unique properties make it ideal for photonic sails on probes designed to swiftly exit our Solar System, as noted by leading astronomers. Exceptional Properties of Aerographite Composed of

NASAs Perseverance spacecraft, carrying the rover to Mars, encountered minor technical issues while passing through Earths shadow, entering safe mode temporarily. Officials remain confident in the missions progress. Could Mars have once supported extraterrestrial life? Thats the key question NASAs P

A strikingly long and slender water ice cloud has reemerged over Mars massive 20-km-high shield volcano, Arsia Mons. Scientists anticipated its return, yet the exact processes driving its formation remain an intriguing puzzle. This isnt a volcanic smoke plume—its composed of water ice crystals. ESAs

Northwestern University researchers have engineered a promising biomaterial to safeguard astronauts from deadly radiation during deep-space journeys to Mars. A Hostile Radiation Environment Beyond the engineering hurdles of crewed Mars missions lies a critical threat: intense radiation exposure. Thi

Chinas Tianwen-1 mission, now hurtling toward Mars, has delivered a striking black-and-white photo of Earth and the Moon from approximately 1.2 million kilometers away. Launched on July 23, 2020, Tianwen-1 marks Chinas ambitious first attempt at Mars exploration, featuring an orbiter and a rover. Mi

During its at least two-year mission on Mars, NASAs Perseverance rover must endure harsh conditions that limit solar power. Thats why engineers equipped it with plutonium-based nuclear energy. NASAs Mars 2020 mission successfully launched Perseverance to search for signs of ancient microbial life in

Two 14-year-old sisters from India have achieved a remarkable feat through a NASA-partnered program. Vekariya and Radhika Lakhani identified a new near-Earth asteroid currently orbiting Mars. Rest assured, it poses no threat to our planet for approximately a million years. Spotting a Near-Earth Aste
