The largest planet in the solar system is putting on a show no telescope has fully caught before. New data from the James Webb Space Telescope shows the gas giant’s auroras flickering in bursts measured in seconds, not minutes. Scientists now face fresh questions about where that power comes from.
A newly discovered asteroid designated 2025 KF will fly by Earth at a distance of 0.3 LD / 0.00077 AU (114 000 km / 71 222 miles) from the center of our planet on May 21, 2025.
A visible aurora has been recorded from the surface of Mars for the first time. NASA’s Perseverance rover detected a faint green glow of atomic oxygen triggered by a solar storm, confirming long-standing predictions about atmospheric emissions. The detection provides a new way to study Martian space weather from the surface.
Search efforts are underway in Western Australia’s Wheatbelt region following a bright green-white fireball that streaked across the sky at 05:57 local time (AWST) on May 11, 2025.
The newly launched Atomic Clock Ensemble in Space (ACES) mission will advance our understanding of how gravity affects the passage of time. By comparing highly accurate clocks aboard the International Space Station with those on Earth, ACES aims to test key concepts in Einstein’s theory of relativity and explore fundamental physics.
A newly discovered asteroid, 2025 FA22, has climbed into the top five positions of the European Space Agency’s (ESA) risk list due to its low but measurable chance of striking Earth in 2089. During the first four months of 2025, more than 1 000 new NEOs have been discovered, in line with the recent average of about 3 000 per year.
The Eta Aquariid meteor shower, caused by debris from Halley’s Comet, peaks on May 5–6, 2025. Observers in the Southern Hemisphere may see up to 50 meteors per hour under dark skies before dawn, while those in mid-northern latitudes may observe 10–20 meteors per hour.
A new study proposes that Mars once had a fully molten core, potentially explaining the planet’s hemispheric magnetic field asymmetry. The model links this anomaly to heat loss concentrated in the southern hemisphere, driven by differences in crustal thermal conductivity. The findings offer new insight into Mars’ early interior dynamics and atmospheric evolution.
Gold may not come from where you think. According to new research, some of the gold found in objects like phones and laptops could have been forged in violent magnetar explosions billions of years ago.
Kosmos 482, a Soviet descent module built to survive Venus’s atmosphere, is expected to reenter Earth’s atmosphere between May 8 and 11, 2025, with a high probability of debris survival due to its robust design.
