In a remarkable astronomical discovery, scientists have found rare evidence that two planets collided in a distant star system. This dramatic cosmic event was detected not by directly seeing the planets crash, but by observing strange changes in the light of a distant star. The findings provide important clues about how planets form and how solar systems evolve over time. The discovery was led by Anastasios (Andy) Tzanidakis , a doctoral candidate in astronomy at the University of Washington. While studying old telescope data from 2020, he noticed something unusual about a star called Gaia20ehk . Located about 11,000 light-years away from Earth in the constellation Puppis , this star appeared to be behaving very strangely. Normally, stars like Gaia20ehk are stable and predictable. It belongs to a category known as main sequence star , similar to our own Sun . Such stars usually shine with steady brightness. However, Gaia20ehk began showing unusual fluctuations in its light, puzzling a...
