A dead star's mysterious rings reveal what could happen when our Sun dies

Astronomers have discovered a strange double ring of planetary wreckage around a dead star, revealing a possible preview of our Solar System's distant future. The two rings are separated by a mysterious gap that researchers believe is maintained by surviving planetary bodies, including one potentially as large as Pluto or the Moon. Their different chemical compositions suggest they may contain the remains of separate destroyed planets.

400,000-year-old teeth reveal a stunning twist in human evolution

A groundbreaking discovery is rewriting the story of human evolution, revealing that an ancient human species once thought to be an evolutionary dead end may have left genetic traces in people alive today. By extracting proteins from 400,000-year-old Homo erectus teeth discovered in China, scientists uncovered evidence suggesting that these early humans interbred with Denisovans, another mysterious ancient human group. That genetic connection may have eventually reached modern populations in the Philippines, Papua New Guinea, and other parts of Southeast Asia.
