Get ready for a celestial spectacle! Europa's Journey Across Jupiter is a must-watch event for all astronomy enthusiasts. But here's the twist: it's not just Europa that's making the journey, but also its shadow, creating a unique and captivating display.
Tonight, February 8, the icy moon Europa will transit Jupiter, accompanied by its dark shadow, visible on the planet's cloud tops. This transit begins around 10 P.M. EST, with Jupiter high in the sky, offering an excellent viewing opportunity. If you zoom in with a telescope, you'll notice an interesting arrangement of moons: Io on the western side, Europa approaching from the east, Ganymede farther east, and Callisto beyond.
Europa's transit starts at 9:54 P.M. EST, and its shadow follows suit around 11:20 P.M. EST. By midnight, both Europa and its shadow will be clearly visible, with Europa approaching the western limb and its shadow well separated from the eastern limb. This celestial dance will continue until around 12:45 A.M. EST, with Europa's shadow disappearing shortly before 1:15 A.M. EST.
The time between moons and their shadows crossing has been increasing since Jupiter's opposition last month, and this trend will continue as we move farther from that date.
In addition to this celestial event, we have a special treat for early risers. The Last Quarter Moon, occurring at 7:43 A.M. EST on Monday, February 9, is best viewed in the early morning hours. This phase offers a unique view of our satellite, visible even after sunrise.
An hour before dawn this morning, the Moon will be high in the southern sky, nestled among the stars of Libra and to the right of Scorpius' claws. This is a beautiful sight to behold through binoculars or a small telescope, revealing the Apennine Mountains in the lunar north, just on the sunward side of the terminator. Below, you'll find the bright and round crater Copernicus, with its distinctive rays stretching across the terrain, a reminder of the impact that formed it.
So, mark your calendars and set your alarms! This week's sky events are not to be missed. And this is the part most people miss: the beauty of astronomy lies not just in the big events, but also in the subtle changes and unique phenomena that occur every day.
