Nickname New Horizons' next target

The craft that flew by Pluto in 2015 is heading for a Kuiper Belt object currently designated 2014 MU69. The mission team wants you to help nickname it.

Wow! Juno's 8th science flyby of Jupiter

A new and awesome batch of images has emerged from the Juno mission's most recent flyby of Jupiter. Plus, the mission gets a new project manager.

Watch for Jupiter below Venus!

Have you seen Jupiter yet? We're hearing from a few people who have. Bright Jupiter will emerge from the dawn glare to meet even brighter Venus on November 13. 

Tonight … Moon and Regulus, late night to dawn

They'll be close from moonrise on, and highest in the sky on Saturday morning. In the coming mornings, watch the moon edge toward Venus and Jupiter before dawn.

Friday FAQ … Why do trees shed their leaves?

Something to think about while you’re raking.

We sold out of these calendars quickly last year. Get yours now! P.S. They make great holiday gifts.

Moon and Regulus, late night to dawn

Not shown on this chart … If you see them around dawn, notice the lighted face of the moon points toward 2 bright objects near the sunrise. Brighter one is Venus. Fainter one (but still bright) is Jupiter.

The zombie star that wouldn't die
Supernovae like this one - designated iPTF14hls - usually remain bright for about 100 days. This one stayed bright for 600 days. Then, astronomers found a 1954 explosion in the same spot in the sky.
What makes zombie ants obey
Zombie ant fungus doesn't attack ants' brains. Instead, the fungus invades an ant's entire body, forming an interconnected 3-D network, forcing the ant to move.
Today in science: Carl Sagan's birthday
For many, for decades, Carl Sagan's name was synonymous with astronomy.
Sky bear comes to Earth in November
Every year, the Big Dipper (Great Bear) descends to its lowest point in the sky on November evenings.
