Weather permitting, a good show Sunday night

 

A SPECIAL CONJUNCTION OF THE MOON AND JUPITER: This weekend, the Moon and Jupiter are converging in the constellation Libra for a special conjunction. Jupiter is approaching Earth for a close encounter in early May, making the giant planet extra big and bright. On Sunday night, April 29th, the Moon will turn full just as it glides past the brightening gas giant. It adds up to a display of rare brilliance in the midnight sky. Visit Spaceweather.com for sky maps and more information.

Conjunctions between the Moon and Jupiter are not uncommon–but this one is special. It’s happening only days before Jupiter’s closest approach to Earth in early May. As a result of its proximity, Jupiter is shining brighter than any star in the night sky. For instance, on the night of the conjunction Jupiter will be almost 3 times brighter than brilliant Sirius. The giant planet will have no trouble being seen next to the glaring full Moon.  Even cheap department store optics will reveal Jupiter’s alternating cloud belts and four largest moons: Io, Europe, Callisto and Ganymede.

Finding the conjunction is easy. Just look east-southeast after sunset. You’ll see the Moon and Jupiter rising together as a pair. They will remain visible all night long, highest in the sky at midnight, but beautiful at any time. Enjoy the show!
