Is there life on Mars? NASA to reveal major evidence from groundbreaking Mars findings
NASA will reveal new findings from the Perseverance rover on September 10, 2025. The focus is on the 'Sapphire Canyon' rock sample from Jezero Crater. Scientists are intrigued by chemical patterns and organic molecules. These could indicate ancient biological processes. The discovery strengthens the case for past microbial life on Mars.
Sunita Williams’ childhood dream was far from rockets and spacewalks; here’s what she dreamed of becoming and why
Sunita Williams, globally recognized for her space missions, initially aspired to be a veterinarian. Inspired by her brother's Naval Academy experience and the movie 'Top Gun,' she joined the US Navy and became a helicopter pilot. Later, NASA selected her as an astronaut.
Humans can’t live beyond 150 years: Scientists expose the harsh reality
Research indicates a potential human lifespan limit between 120 and 150 years, regardless of lifestyle. A study in Nature Communications reveals that the body's resilience declines with age, impacting recovery from illnesses. Analyzing blood cell counts and physical activity, scientists found a point where the body can no longer fully recover, suggesting a biological ceiling on longevity.
NASA warns! 100-foot asteroid 2025 QV9 racing towards Earth at over 10,000 mph on September 10; should we be concerned
NASA confirms that asteroid 2025 QV9 will fly by Earth on September 10. The asteroid is airplane-sized and travels at high speed. It will pass at a safe distance, about five times the Moon's distance. Scientists monitor such near-Earth objects. Agencies like NASA, ESA, JAXA and ISRO are tracking asteroids. ISRO plans to study asteroids like Apophis.
NASA chief Sean Duffy draws unexpected parallels: ‘Space economy is like the iPhone’ — Here’s why
NASA's acting administrator, Sean Duffy, likened the burgeoning space economy to the early days of the iPhone, suggesting its transformative potential is still unfolding. Speaking on NASA's podcast, Duffy highlighted that investments in lunar missions and private space ventures could reshape society unpredictably.
NASA James Webb Telescope reveals promising signs of a distant Earthlike atmosphere similar to ours
The James Webb Space Telescope cannot observe Earth directly. It is too bright and could damage the telescope. However, studying Earth's potential appearance to Webb helps scientists. It refines methods for analyzing exoplanets. Earth's atmospheric fingerprint serves as a benchmark. Scientists compare it to other worlds. This identifies planets with habitable conditions.
Earth in danger! 60% of global land now beyond safe ecological limits, scientists warn
A recent study reveals that human activities have pushed 60% of Earth's land outside the safe operating zone, threatening ecosystems. Deforestation, agriculture, and industrial expansion have disrupted carbon, water, and nitrogen cycles, particularly in Europe, Asia, and North America. Scientists urge immediate global action to protect natural systems and prevent irreversible damage to food security, water supplies, and the climate.
Total lunar eclipse 2025 lights up the night sky with a rare red Moon spectacle; here’s when and where to watch the next ‘blood moon’ in the US
Skywatchers in North America are gearing up for a rare celestial event: the total lunar eclipse on March 2-3, 2026. This "blood moon" will transform the lunar surface into a fiery red spectacle, visible with the naked eye. The eclipse offers a breathtaking display, with optimal viewing in the western US and Canada.
Scientists discover how Earth’s interior took shape in its first 100 million years
A new study reveals Earth's essential features formed within its first 100 million years, challenging long-held theories. Using geochemistry and computer simulations, researchers discovered the planet's molten interior cooled and solidified into distinct layers much earlier than previously thought. These findings offer insights into the evolution of rocky planets and the potential for life beyond Earth.
SpaceX gets FAA approval to ramp up Falcon 9 launches at Florida’s Cape Canaveral
The FAA has approved SpaceX's plan to significantly increase Falcon 9 launches at Cape Canaveral, allowing up to 120 launches annually and the construction of a new booster landing pad. This expansion, while avoiding a full Environmental Impact Statement, still adheres to environmental regulations. Most booster recoveries will continue via droneships, supporting SpaceX's growing satellite deployments and crewed missions.
