🚨 New discovery alert! 🚨 Astronomers have just captured something we've never seen before: the birth of a solar system. 🍼🪐 Yes, we've spotted baby planets before, but never this early in their development. The star system is called HOPS-315, located in Orion about 1,370 light-years away, and it’s giving us a glimpse of what our own Sun might’ve looked like when it was just 100,000 to 200,000 years old. Here’s what’s happening: Scientists used ALMA (which sees in submillimetre wavelengths, between infrared and radio light) to capture this image of HOPS-315. They saw a disk of silicon monoxide forming around the baby star. But here’s the wild part: that material is condensing into crystalline silicates. These are the exact kind of minerals we find on Earth in sand, rock, and even concrete. 🪨 Why is that so cool? Because these are the first solid ingredients believed to kick off planet formation, and exactly what we think happened in our Solar System 4.5 billion years ago. 🌍 Until now, we could only guess that this happened in other systems based on asteroid samples. But now we've seen it in action in a different star system. So... are we special? Or is this just how planets are made across the cosmos? Here’s the original research if you want to dive deeper: https://www.nature.com/articles/s41586-025-09163-z #Astronomy #SpaceNews #PlanetFormation #SolarSystem #ALMA
