Blue Origin successfully launched its New Glenn rocket from Cape Canaveral, carrying two NASA Mars orbiters called Escapade, marking the rocket’s second flight and the first successful booster recovery on a barge. The orbiters will spend a year near Earth before using a gravity assist to reach Mars in 2027, where they will study the planet’s upper atmosphere, magnetic fields, and interaction with solar wind … Continue reading Blue Origin launches rocket carrying twin Nasa spacecraft to Mars

Three Chinese astronauts returned from the Tiangong space station Friday after a nine-day delay caused by damage to their original Shenzhou-20 return capsule, likely from space debris. They instead returned in the newly arrived Shenzhou-21, which had delivered a replacement crew, completing China’s longest space station stay at 204 days. The capsule landed in the Gobi Desert, where the crew was safely recovered, along with … Continue reading Chinese astronauts return from space station after delay blamed on space debris damage

Blue Origin’s New Glenn rocket launch was postponed Wednesday due to intense solar storms, which were also creating spectacular auroras across the U.S. The rocket, carrying two NASA Mars orbiters from Florida, had already faced delays from poor weather. NASA delayed the liftoff over concerns that heightened solar radiation could affect the spacecraft. No new launch date has been announced, the AP has reported. This … Continue reading Solar storms delay the launch of Blue Origin’s big new rocket with Mars orbiters for NASA

Space weather forecasters have issued an alert for incoming severe solar storms that could produce bright northern lights and temporarily disrupt communications. Several recent coronal mass ejections from the sun are expected to reach Earth Tuesday night into Wednesday, potentially affecting radio, GPS, and other systems. Auroras may be visible across much of the northern U.S., and as far south as Alabama and Northern California, … Continue reading Space forecasters say severe solar storms could hit Earth and trigger auroras

The Shenzhou-20 crew stranded at China’s Tiangong space station is reported to be in good condition, working and living normally, China’s Manned Space Engineering Office said Tuesday. Their scheduled Nov. 5 return to Earth was delayed after the spacecraft was believed to have been struck by a small piece of space debris. The return has been postponed to an unspecified date, with the mission team … Continue reading China’s stranded astronauts ‘in good condition’ after space debris delays planned return

Astronomers studying interstellar comet 3I/ATLAS have found evidence that its surface has been altered by galactic cosmic ray (GCR) processing, suggesting the comet’s outer layers are not pristine material from another star system. Detected in July 2025, 3I/ATLAS is the third confirmed interstellar object, and its unusually high carbon dioxide–to–water ratio (CO₂/H₂O ≈ 7.6) puzzled researchers. After testing various formation and chemical scenarios, scientists concluded … Continue reading 3I/ATLAS Shows Evidence Of “Galactic Cosmic Ray” Processing

Researchers at the University of Stuttgart have developed a compact short-pulse laser achieving up to 80% efficiency—more than twice that of many current systems—by using a multipass design that reuses light within a small crystal. The palm-sized device delivers ultrashort light pulses lasting billionths to quadrillionths of a second, enabling high-precision energy delivery for applications in medicine, manufacturing, analytics, and quantum science. Traditional high-efficiency short-pulse … Continue reading Tiny laser could transform medicine and quantum science

Astronomers have observed the largest and most distant flare ever detected from a supermassive black hole, nicknamed “Superman,” originating 10 billion light-years away. At its peak, the flare shone with the brightness of 10 trillion suns. The flare came from an active galactic nucleus (AGN), where gas and dust spiraling into a supermassive black hole become superheated, emitting intense radiation. Researchers believe the black hole … Continue reading Largest observed flare from a black hole unleashes the light of 10 trillion suns

China’s Shenzhou-20 crewed spacecraft has delayed its return to Earth after possibly being struck by small pieces of space debris, the China Manned Space Agency (CMSA) announced. The delay is under review as officials conduct impact analysis and risk assessments, though no new landing date has been provided. Shenzhou-20 is docked at the Tiangong space station alongside Shenzhou-21, currently in a handover period, and if … Continue reading China’s Shenzhou-20 return mission delayed due to space debris impact

The U.S. military is close to fielding two new satellite‑jamming systems — L3Harris’s Meadowlands and Remote Modular Terminals — which, along with an upgraded Counter Communications System, will give the Pentagon three openly acknowledged counter‑space jammers. Meadowlands is in final training and exercises and is expected to be fielded this fiscal year, while the Remote Modular Terminals are being deployed overseas in a limited early‑use … Continue reading US Space Force to Use Three Weapons To Jam Chinese Satellites Via Remote Control

Harvesting helium-3 is technically challenging, requiring massive … Continue reading Mining Company Says It’s Identified Hugely Valuable Material on Surface of the Moon

3I/ATLAS, only the third known interstellar object to enter our solar system, has intrigued scientists since its discovery in early July. Likely a comet, it reached its closest point to the Sun on October 29, brightening much faster than expected. Observations from NASA’s STEREO, ESA’s SOHO, and NOAA’s GOES-19 satellites showed this rapid luminosity increase, which may be linked to its extreme speed of 137,000 … Continue reading Mysterious Interstellar Object Has Unexpectedly Started Brightening, Scientists Say

China’s Shenzhou 21 spacecraft successfully docked with the Tiangong space station at a record speed, completing the maneuver in about 3.5 hours—three hours faster than previous missions. The crew includes commander Zhang Lu, returning from Shenzhou 15, and two first-time astronauts: engineer Wu Fei, China’s youngest space traveler at 32, and payload specialist Zhang Hongzhang. During their roughly six-month mission, the team will conduct 27 … Continue reading China’s Shenzhou 21 docks with space station, sets the country’s own speed record

Researchers from Stockholm University and Vanderbilt University claim to have found evidence linking mysterious sky flashes from the 1940s and 1950s to nuclear weapons testing sites in the U.S. The flashes, described as “transient star-like objects,” appeared in historical Palomar Observatory photos taken before the first satellites were launched, ruling out human-made orbital objects. Analysis showed the flashes were 68% more likely to occur the … Continue reading Study finds signs of UFOs near US sites in 1950s
