An interstellar comet spotted earlier this year is on its way to its close approach to the Sun this month, giving astronomers a close-up view of the visitor from outside our solar system.
What's happening: A new photo taken by Yale astronomers shows Comet 2l/Borisov's 100,000-mile-long tail and 1-mile-across nucleus in new detail.
A galaxy with three supermassive black holes swirling within it could help astronomers piece together just how some of the largest galaxies formed.
Why it matters: The discovery in the NGC 6240 galaxy located about 400 million light-years away marks the first time three supermassive black holes have been found in such close proximity to one another. The galaxy gives scientists an unprecedented chance to study the motions of three huge black holes that were once likely parts of three different galaxies as they merge.
