Comet Swan is visible to the naked eye, and it may get even brighter
The visitor from deep space has passed us by, but may be due for an outburst as it careens toward the sun.

Comet Swan has already passed Earth by, but its journey toward the sun could make it more spectacular. It's the latest comet teasing skywatchers with its magnificent tail, which is some 10 million miles (16 million kilometers) long.
Now Comet Swan could deliver on the promise of a rare night sky show that Atlas failed to provide. Already, Swan could be visible to those with exquisitely dark skies and sharp eyes. Others might also be able to spot it with binoculars.
Astronomer Con Stoitsis said some predictions show the comet continuing to brighten in the coming days."It should be an 'obvious' naked eye target in mid-May," he said on Twitter.
The comet made its closest pass by Earth on May 13 and comes nearest to the sun on May 27.
