A nuclear blast could save Earth from an asteroid, but there's a catch

A nuclear explosion might save Earth from a deadly asteroid, but new research suggests that hitting the wrong side could make the difference between success and disaster. Scientists found that an asteroid's irregular shape can dramatically affect how it responds to an X-ray blast, with deflection effectiveness varying nearly fivefold depending on the angle.

NASA’s Swift telescope falls to Earth after nearly 22 years in space

After nearly 22 years of exploring the universe’s most violent explosions, NASA’s Swift Observatory has re-entered Earth’s atmosphere over Indonesia. Originally designed to last just two years, the pioneering space telescope transformed our understanding of black holes, exploding stars, and mysterious cosmic outbursts.

NASA is racing against time to save the Hubble Space Telescope

NASA is exploring a daring plan to save the legendary Hubble Space Telescope from its eventual fiery plunge into Earth's atmosphere. After more than 35 years of groundbreaking discoveries, Hubble is slowly losing altitude, and without intervention, it could fall back to Earth as early as 2033 or 2034. To keep the iconic observatory operating, NASA is asking private space companies to propose innovative ways to boost Hubble into a higher orbit, upgrade its capabilities, or safely dispose of it when its mission finally ends.

Astronaut and Earth

CSA (Canadian Space Agency) astronaut Joshua Kutryk is pictured during the Oct. 29, 2026, spacewalk. The International Space Station was soaring 267 miles above the South Atlantic Ocean at the time of this photograph. Kutryk and NASA astronaut Anil Menon installed a new roll-out solar array on the space station and performed some get-ahead work […]

NASA’s Voyager 1 is about to reach a historic one-light-day milestone

NASA’s Voyager 1 is approaching an extraordinary milestone nearly 50 years after its launch, even as engineers battle dwindling power and mysterious technical problems. A clever energy-saving maneuver has extended the spacecraft’s scientific mission, while an unexplained 48-hour communications blackout recently gave NASA a scare. On November 18, Voyager 1 will reach a distance of one light-day from Earth, making even the simplest round-trip communication take 48 hours.

Scientists begin tests on human composting, an eco-friendly alternative to burials and cremation

Humans have caused irreversible changes to our planet in their time on Earth, pollution that continues even in death. Cremation relies heavily on fossil fuels, while traditional burials take up land. So is there a more eco-friendly way to honour our loved ones? French scientists are exploring the possibility of composting human bodies, a process that returns those who have died to the earth. Our Down to Earth team reports.

Scientists confirm global warming is accelerating faster than ever recorded

Earth is warming faster than ever recorded, with scientists detecting a major acceleration in global temperatures since around 2015. A new study reveals that the warming rate has surged to approximately 0.35°C per decade, nearly double the average pace observed from 1970 to 2015. After removing natural climate fluctuations, researchers confirmed the acceleration with more than 98% statistical confidence.

A mysterious star system just 16 light-years away may be hiding habitable planets

Astronomers have solved a 170-year-old planetary mystery in a nearby two-star system, discovering that a mysterious wobble was caused by stellar activity rather than a giant planet. Although Jupiter-sized worlds have been ruled out in key regions, smaller, potentially habitable planets could still be waiting to be discovered just 16 light-years from Earth.

128,000-year-old ice in Tibet could rewrite climate history

Ancient ice discovered high in Tibet may be more than 128,000 years old, preserving an extraordinary record of Earth's climate that scientists previously thought had been lost. The discovery reveals a rare glimpse into the last ice age and could reshape our understanding of how glaciers survive dramatic changes in global climate.

NASA discovers Jupiter’s invisible shield is more complex than Earth’s

NASA’s Juno spacecraft has discovered that Jupiter uses a surprisingly complex system of powerful plasma waves and multiple shock regions to defend against the solar wind. The findings reveal major differences between Jupiter and Earth and could help scientists understand the enormous shock waves produced by exploding stars.

Scientists discover a hidden oxygen reservoir deep inside Earth

Scientists have discovered that magma deep inside Earth can store surprising amounts of extra oxygen, potentially revealing a hidden contributor to our planet's oxygen-rich atmosphere. The findings suggest that ancient volcanic eruptions may have helped transform Earth's atmosphere billions of years ago, with implications for understanding life on other planets.

Meteors don't just burn up. What really happens is far more violent

Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why meteorites scatter across the ground and how dangerous asteroids explode in Earth's atmosphere.

Earth's ice ages may have been driven by a hidden ocean chain reaction

Scientists have uncovered a surprising connection between Earth's opposite poles that may help explain how the planet plunged into past ice ages. New research suggests that as massive ice sheets expanded across the Northern Hemisphere, they cooled Atlantic Ocean waters that eventually traveled south toward Antarctica. This cooling may have disrupted Southern Ocean circulation, allowing the ocean to absorb and store more carbon dioxide from the atmosphere, further cooling the planet.
