Jupiter, Saturn merging in night sky on Dec 21, closest since Galileo’s time in the 17th century
Cape Canaveral (US), Dec 20: Jupiter and Saturn will merge in the night sky Monday, appearing closer to one another than they have since Galileo's time in the 17th century.
Astronomers say so-called conjunctions between the two largest planets in our solar system aren't particularly rare.
Jupiter passes its neighbour Saturn in their respective laps around the sun every 20 years.
But the one coming up is especially close: Jupiter and Saturn will be just one-tenth of a degree apart from our perspective or about one-fifth the width of a full moon.
They should be easily visible around the world a little after sunset, weather permitting.
Toss in the winter solstice in the Northern Hemisphere, the longest night of the year and the summer solstice in the Southern Hemisphere and this just-in-time-for-Christmas spectacle promises to be one of the greatest of Great Conjunctions.
What is most rare is a close conjunction that occurs in our nighttime sky," said Vanderbilt University's David Weintraub, an astronomy professor.
"I think it's fair to say that such an event typically may occur just once in any one person's lifetime, and I think 'once in my lifetime' is a pretty good test of whether something merits being labeled as rare or special.
It will be the closest Jupiter-Saturn pairing since July 1623, when the two planets appeared a little nearer.
This conjunction was almost impossible to see, however, because of its closeness to the sun.
Considerably closer and in plain view was the March 1226 conjunction of the two planets when Genghis Khan was conquering Asia.
Monday's conjunction will be the closest pairing that is visible since way back then.
Saturn and Jupiter have been drawing closer in the south-southwest sky for weeks. Jupiter bigger and closer to Earth is vastly brighter.
I love watching them come closer and closer to each other and the fact that I can see it with my naked eyes from my back porch! Virginia Tech astronomer Nahum Arav said in an email.
To see it, be ready shortly after sunset Monday, looking to the southwest fairly low on the horizon.
Saturn will be the smaller, fainter blob at Jupiter's upper right. Binoculars will be needed to separate the two planets.
Despite appearances, Jupiter and Saturn will actually be more than 450 million miles (730 million kilometers) apart. Earth, meanwhile, will be 550 million miles (890 million kilometers) from Jupiter.
A telescope will not only capture Jupiter and Saturn in the same field of view, but even some of their brightest moons.
Their next super-close pairing: March 15, 2080.

England sticking with Key, McCullum and Stokes despite Ashes humbling
London (AP): England is not sacking anybody following the 4-1 Ashes loss in Australia.
A review of the tour by the England and Wales Cricket Board, announced within hours of the final match in January, was concluded on Monday. Firing people would “be the easy thing to do,” ECB chief executive Richard Gould said but he insisted, "This is not the time to throw everything out."
Managing director Rob Key, coach Brendon McCullum and captain Ben Stokes kept their jobs after the best England side to go to Australia in 14 years lost the Ashes in 11 days with two games to spare.
“Moving people on can sometimes be the easy thing to do. That's not the route that we're going to take,” Gould said. “I've seen the driving ambition and determination that we're lucky enough to have within our leadership group to take the lessons from the Ashes and move forward.”
Gould previously was the chief executive of Bristol City soccer club and said the ECB would not follow the same route as soccer's hire-and-fire culture.
“Cricket is a very unique sport in that it takes a team of leadership ... it's not like football where there's a single point of failure or success with a manager," he said. He added the ECB would not “select or deselect management based on a popularity campaign.”
The main criticisms of England's tour were poor preparation, player misbehavior, and selection mistakes.
At a press conference at Lord's, Gould and Key said McCullum and Stokes have not had a “bust up,” they did not want McCullum to “completely change” but “to evolve,” the behavior of some players was “unprofessional,” there will be more consequences for underperforming, and a commitment to “better long-term planning” ahead of major test series.
Some changes were already implemented for the Twenty20 World Cup, where England reached the semifinals. Gould implied that performance saved McCullum.
Key acknowledged that England supporters would be disappointed to see the management team go unpunished.
“I know people want punishment and that people then should be sacked for that,” Key said. “That doesn't mean we don't feel like we've gone through some serious pain: Brendon, myself, Ben. It's been as tough a time as I think I've had.”
