00:00Astronomers have discovered three active supermassive black holes inside one ancient galaxy.
00:06The galaxy, known as JASO148-4214, is more than 12.5 billion light-years away.
00:13Its light shows the galaxy as it appeared just 1.2 billion years after the Big Bang.
00:19Researchers used NASA's James Webb Space Telescope to identify the three black holes.
00:24Two are near the galaxy's center, separated by only about 620 light-years.
00:30A third black hole sits roughly 5,500 light-years from the center.
00:34Their estimated masses range from 600,000 to 80 million times the mass of our Sun.
00:40Astronomers say the two central black holes could eventually merge.
00:43That merger could help explain how massive black holes grew so quickly in the early universe.
00:49The discovery offers a rare glimpse into how galaxies and black holes evolved billions of years ago.
