Scientists may have recorded electrical activity—nicknamed “mini lightning”—in Mars’ atmosphere for the first time, using audio and electromagnetic data from NASA’s Perseverance rover. The discharges were linked to dust devils and dust storm fronts in the Jezero Crater region, suggesting Mars can generate atmospheric electricity. The findings, analyzed over 28 hours of recordings spanning two Martian years, have implications for Martian chemistry, climate, habitability, and … Continue reading Lightning detected on Mars for the first time, scientists say

For the first time, magnetic switchbacks—zigzag-shaped kinks in plasma previously only seen near the Sun—have been detected in Earth’s magnetic field. Physicists Emily McDougall and Matthew Argall discovered these structures while analyzing data from NASA’s Magnetospheric Multiscale mission, finding that solar plasma interacting with Earth’s local magnetic fields caused the switchbacks. Switchbacks form when open magnetic field lines from the Sun reconnect with closed loops, … Continue reading Unexpected ‘Zigzag’ Structures Discovered in Earth’s Magnetic Field

Astronomers have now cataloged over 40,000 near-Earth asteroids (NEAs), ranging from a few yards to several miles wide, enhancing both scientific knowledge and planetary defense. NEAs are closely monitored because even small asteroids can cause serious regional damage if they impact Earth, with software predicting their paths decades or centuries in advance. Discovery rates surged in the 1990s and 2000s and continue to grow with … Continue reading Astronomers confirm 40,000 near-Earth asteroids within striking distance

The Voyager spacecraft, launched in 1977, are the farthest human-made objects from Earth, traveling over 12 billion miles at speeds of 38,000 mph. Originally tasked with studying the outer planets, they now journey into interstellar space, providing insights into the solar system’s boundary. Both spacecraft encountered a “wall of fire” at the heliosphere’s edge, where temperatures reached up to 90,000°F, marking the transition from solar … Continue reading At The Edge Of Our Solar System, NASA’s Voyager 1 Found A ‘Wall Of Fire’

Over northern Italy, a rare atmospheric phenomenon known as an “elve” appeared as a glowing red ring above the Alps, captured by photographer Valter Binotto on November 17. Elves are brief, disk-shaped flashes caused by powerful electromagnetic pulses from lightning striking the ionosphere, lasting less than a thousandth of a second and spanning hundreds of miles. The event Binotto photographed was triggered by a massive … Continue reading Photographer captures eerie red halo hovering over the Italian Alps

Comet C/2025 K1 (ATLAS) has begun breaking apart after its close approach to the sun on October 8, with images showing multiple fragments of its icy nucleus. Astronomer Gianluca Masi captured animations from stacked exposures taken between November 11 and 18, revealing three, possibly four, distinct pieces. Earlier observations from Italy’s Asiago Observatory showed two fragments about 1,200 miles apart, with hints of a smaller … Continue reading Comet C/2025 K1 (ATLAS) breaks apart in incredible telescope photos
