Comet 3I/ATLAS is the third interstellar visitor and continues to be a treasure trove of information about the condition of its formation. As it speeds through the Solar System, telescopes have been pointed at it, revealing new tidbits about this fascinating space rock. Just recently, we have learned about the unusual ratio of nickel to iron (both common in comets); …

Siberian Meteorite Impact Created Massive Diamond Crater While Debris Formed Planetary Rings
IN A NUTSHELL 🌍 Popigai Crater in Siberia, formed by a massive meteorite impact, is the fourth-largest known on Earth. 💎 The impact at Popigai transformed graphite into industrial-quality diamonds due to extreme pressure. 🌌 North American Tektite strewn field possibly formed rings around Earth, influencing climate change. 🦖 The Eocene–Oligocene extinction event saw significant species loss, particularly among aquatic …

On Sept. 11, 2022, engineers at a flight control center in Turin, Italy, sent a radio signal into deep space. Its destination was NASA’s DART (Double Asteroid Redirection Test) spacecraft flying toward an asteroid more than 5 million miles away. The message prompted the spacecraft to execute a series of pre-programmed commands that caused a small, shoebox-sized satellite contributed by the …

So much for heliocentrism. An international team of astronomers using observations made with the James Webb Space Telescope have found evidence of massive planets out there that’re capable of forming their own planetary systems — without a star. These planets would be the center of something like a mini version of our solar system where other, smaller planets revolve around …

The Hera mission to follow-up on the aftermath of NASA’s DART asteroid crash has caught sight of two other asteroids in an important test of its camera ahead of its rendezvous its main target: the double space rock system of Didymos and Dimorphos. In September of 2022, NASA’s Double Asteroid Redirection Test, or DART for short, slammed into the small …
