A team of scientists from South Africa has discovered evidence partially supporting a hypothesis that Earth was struck by a meteorite or asteroid 12,800 years ago, leading to global consequences including climate change, and contributing to the extinction of many species of large animals at the time of an episode called the Younger Dryas.
Read moreAstronomers have discovered a collection of 12 galaxies which existed about 13.0 billion years ago. One of the 12 galaxies is a giant object, known as Himiko, which was named for a mythological queen in ancient Japan. This discovery suggests that large structures such as protoclusters already existed when the Universe was only about 800 million years old, 6% of its present age.
