Venus' Winds Race Around The Planet At Extreme Speeds Due To Solar Heat
New findings suggest that diurnal tides, driven by solar heat, are a major contributor to the extreme speeds of Venus's winds.

Artemis Era Raises Safety Concerns as Lunar Orbit Nears Capacity, New Study Finds
As lunar exploration surges, scientists warn that the Moon’s limited stable orbits are growing crowded. Georgia Tech simulations suggest that with about 50 satellites, each may need several collision-avoidance maneuvers per year. Even now, orbiters like Chandrayaan-2 require frequent course corrections. With Artemis and private missions incoming,...

Satellites Capture Record-Breaking 20-Metre Waves Crossing Entire Oceans
ESA satellites have recorded the world’s largest ocean swells — nearly 20 meters high — generated by Storm Eddie in the North Pacific. These giant waves carried storm energy over 24,000 kilometers, reaching distant coasts and proving that ocean swells can transport immense power across the globe even when storms stay offshore.

Tiny Asteroid 2025 TF Zooms Past Earth Undetected, Closer Than Satellites
A small asteroid named 2025 TF surprised astronomers after flying only 265 miles above Antarctica, lower than many satellites. Detected post-passage by ESA, it underscores the challenge of spotting small, fast-moving space rocks before they come close to Earth.

Ariane 6 Launches Metop-SGA1 Weather Satellite into Polar Orbit
Europe’s heavy-lift Ariane 6 rocket completed its third successful launch on Aug. 12, 2025, lifting off from Kourou, French Guiana at 8:37 p.m. EDT. The mission carried Metop-SGA1, an 8,900-pound next-generation polar-orbiting weather satellite operated by EUMETSAT. Placed into an 800 km polar orbit 64 minutes after liftoff, Metop-SGA1 will deliv...

Two Spacecraft Recreate Artificial Solar Eclipses to Observe the Sun’s Superhot Corona
Twin satellites in ESA’s Proba-3 mission have successfully recreated artificial solar eclipses from space to examine the sun’s million-degree corona. The breakthrough will allow continuous observations of the sun’s outer atmosphere, offering rare insights that natural eclipses on Earth can’t provide. The mission marks a major step in solar ...

ESA's Proba-3 Unveils First-Ever Artificial Solar Eclipse Images from Precision Satellite Formation
ESA’s Proba-3 mission has captured the first artificial solar eclipse from space using two satellites flying in precise formation. This breakthrough allows frequent, high-resolution imaging of the sun’s corona, bypassing the rarity of natural eclipses. The mission opens new frontiers in solar physics and space weather research with open access ...
