Bush fires that had been on the […]
In a few hours, the near-Earth Asteroid 2024 JN16 will have an extremely close, but safe, encounter with us, coming at 19.000 km from the Earth’s surface, about 50% of the geostationary satellites distance. The Virtual Telescope Project will show it to you live! Near-Earth asteroid 2024 JN16: poster of the event. The near-Earth asteroid 2024 […]
