Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

NGC 3603-A1 is a pair of giant stars locked in a rapid 3.8-day orbit. Their dynamic relationship provides clues to how massive stars evolve and form black holes. A team of astronomers combined archiva ...

When the "little red dots" were first discovered in 2022, scientists thought the objects might be galaxies as mature as the Milky Way, which is about 13.6 billion years old. That's because galaxies ...
