Jupiter and Saturn, the two largest planets in the Solar System, were stationed in nearly the same spot in the night sky on Monday, creating a bright spectacle.The positions of the two planets align once every 20 years, according to NASA. While conjunctions happen several times during the course of a typical lifetime, a conjunction of this magnitude is quite rare. The last time the two planets were this close to each other in the night sky was 400 years ago, but no one was able to see it as that conjunction occurred during the day.The last time a conjunction of his magnitude happened at night was 800 years ago.So what causes the conjunction?“You can imagine the solar system to be a racetrack, with each of the planets as a runner in their own lane and the Earth toward the center of the stadium,” said Henry Throop, astronomer in the Planetary Science Division at NASA Headquarters in Washington. “From our vantage point, we’ll be able to be to see Jupiter on the inside lane, approaching Saturn all month and finally overtaking it on December 21.”The timing of the conjunction adds to the spectacle. Monday also marks the winter solstice.Being four days before Christmas, some are dubbing the event as “The Christmas Star,” although the conjunction is of planets and not stars. Scientists have long speculated whether the Star of Bethlehem was the 7 BC conjunction of the two planets.“Conjunctions like this could happen on any day of the year, depending on where the planets are in their orbits,” said Throop. “The date of the conjunction is determined by the positions of Jupiter, Saturn, and the Earth in their paths around the Sun, while the date of the solstice is determined by the tilt of Earth’s axis. The solstice is the longest night of the year, so this rare coincidence will give people a great chance to go outside and see the solar system.”While the two planets will have the appearance of being very close to each other, in reality, they will be hundreds of millions of miles apart.For the next few days, Saturn and Jupiter will remain very close to each other in the night sky. The best time to view the planets will be roughly one hour after sunset in the southwest sky. Jupiter will appear to be brighter than Saturn as its closer and larger. 2278

Jimmy Kimmel didn't pull any punches when it came to the Senate's new health care bill and U.S. Sen. Bill Cassidy, saying that Cassidy lied "right to my face.""A few months ago after my son had open heart surgery, which was something I spoke about on the air, a politician, a Senator named Bill Cassidy from Louisiana was on my show and he wasn't very honest," Kimmel said opening Tuesday night's show.Kimmel then explained how Cassidy came up with what the senator called the "Jimmy Kimmel Test," which according to the host was a test that said that "No family should be denied medical care, emergency or otherwise because they can't afford it." 655

Joe Biden was officially nominated as the Democratic nominee for president on Tuesday at the virtual Democratic National Convention. Delegates cast their votes virtually as the in-person convention was canceled due to the coronavirus pandemic. Tuesday's roll call was merely a formality as Biden accumulated more than 50% of pledged delegates during the primaries. Biden is now the nominee-in-waiting, and he will accept the party's nomination on Thursday from Wilmington, Delaware. 490
