Scientists believe there is an ocean hidden beneath the surface of Jupiter’s moon Europa. NASA-JPL astrobiologist Kevin Hand explains why scientists are so excited about the potential of this ice-covered world to answer one of humanity’s most profound questions.
If you are willing to get up extra early this week, you can catch Jupiter and Venus getting flirty and close together in the early-morning sky. This meeting of the 2 planets, also known as a conjuction, occurs in pairs with 10 months separating the conjunctions Joe Rao for Space.com tells us more:
The two brightest planets, Venus and Jupiter, will appear super-close together before sunrise on Monday morning (Aug. 18), and it’s just the kickoff for a week of early-bird observing by stargazers.
This entire week is an exceptional time for predawn skywatchers to see the stunning sight of Venus and Jupiter together in the sky. The best time to see the two planets about 45 minutes before sunrise, when they will be visible low on the east-northeast horizon.
And if you are willing to wait until Saturday you’ll see even more!
On Saturday, Aug. 23, the gap between Venus and Jupiter will have widened to 5 degrees (roughly the separation between the two pointer stars in the bowl of the Big Dipper). On that night a narrow crescent moon will join the two planets, making for a striking triangle configuration in the morning twilight.
