How your flight home could be broadcasting Earth’s location to aliens
- Airport radar systems worldwide are unintentionally broadcasting powerful signals into space, potentially announcing humanity's existence to alien civilizations up to 200 light years away.
- The radar emissions could be detected by extraterrestrials with radio telescopes, revealing Earth's 'hidden electromagnetic leakage' and unintentional technosignatures.
- The research explores how radar signals from Earth would appear to nearby star systems, indicating that any planet with advanced technology and aviation systems could produce similar electromagnetic signatures.
- This unintentional cosmic broadcasting poses new opportunities for SETI researchers to detect signs of intelligent life beyond traditional intentional messages, potentially connecting Earth with alien civilizations within our galactic neighborhood.

Trump administration reportedly planning to fire 2,145 Nasa employees
- The Trump administration is reportedly planning to cut at least 2,145 high-ranking NASA employees with specialized skills or management responsibilities.
- The layoffs are part of an effort to reduce the federal government's size through early retirement, buyouts, and deferred resignations, affecting key mission areas like science and human space flight, as well as support roles like information technology.
- Former Nasa officials have criticized the White House's proposed 47% cuts to Nasa science activities in the 2026 budget, warning that it may jeopardize US leadership in space exploration and give an edge to China's aggressive space program.
- Trump's administration withdrew its nominee for NASA administrator, Jared Isaacman, leading to criticism and accusations of retaliation against Elon Musk, who had proposed Isaacman for the role.

JWST discovery helps answer how galaxies, like our own Milky Way, were born
- Galaxies started as thick discs before forming the thin discs we see now.
- Using JWST, scientists observed galaxies more than 10 billion years old.
- Thick discs serve as the foundation before thin discs give galaxies their shape.
- Scientists debate theories on disc formation, including 'born hot' and 'progressive thickening.'
- JWST findings reveal the intricate formation process of galaxies over billions of years.

Discovery of ancient riverbeds suggests Mars once wetter than thought
- Discovery of thousands of miles of ancient riverbeds in the heavily cratered southern highlands of Mars indicates the planet was once much wetter than previously believed.
- The riverbeds, believed to be over 3 billion years old, were revealed in high-resolution images, showing networks of rivers stretching for more than 100 miles in some areas, likely replenished by regular precipitation.
- Researchers focused on Noachis Terra, one of the oldest terrains on Mars, using high-resolution images from NASA's Mars orbiters to identify geological features like fluvial sinuous ridges, indicating an enduring presence of water about 3.7 billion years ago.
- The findings challenge previous assumptions about the lack of evidence for water on Mars in some regions and suggest that Mars was once a far wetter world before becoming the arid planet it is today, with the possibility of hidden water reservoirs deep beneath the surface.

Tire Technology: Durability and Traction Inspired by the Moon, Not Born in Space
- Goodyear developed a mesh wire tire design made of zinc-coated piano wire for Lunar Roving Vehicle (LRV) wheels to endure extreme temperatures and rough lunar terrain without air.
- The lunar tire design was a specialized adaptation of tire engineering that redirected engineering principles rather than being a new invention.
- Although different from Earth-bound radial tires, the lunar tire set the stage for innovative tire materials and structures, improving traction on varied terrains.
- Materials initially researched for space exploration, like advanced polymers and metal reinforcements, have influenced the composition of modern tires, enhancing their durability and resilience.

Crashing into an asteroid creates chaotic space boulders
- A recent study published in the Planetary Science Journal revealed that crashing a spacecraft into the asteroid moon Dimorphos caused chaotic movements of boulders and altered the space rock's orbit.
- The impact of the spacecraft and the resultant ejected boulders carried significant momentum, complicating future asteroid deflection attempts.
- Observations from the LICIACube spacecraft showed that the boulders were not randomly scattered, indicating the presence of unknown forces shaping their trajectories.
- Insights from this study are crucial for planning future asteroid deflection missions, highlighting the importance of considering various variables to ensure mission success.
