See these awesome pictures of the starry skies and the rendezvous between Jupiter and Saturn as seen from earth in December 2020 to remind us of our place in the vast Milky Way and outer space. Jupiter takes 12 years to circle the sun, Saturn 30 years they came this close in 1623. As Giles Sparrow points out in his book "21 Stars in The Milky Way," ther are 200 billion stars, and distances are vast beyond comprehension. Thousands of years for light travelling at 300,000 kilometres a second to get to earth from distant stars in The Milky Way! Think of that and there is so little we know at this time of the pandemic about so many things!

From Kansas to Southern Spain, pictures from The Guardian show the great conjunction of Jupiter and Saturn in the night skies looking out into The Milky Way in December 2020. At the time of the pandemic understanding how small our world is on this planet as light travels at 300,000 kilometres per second and it takes 2 seconds to reach earth from the moon, thousands of years for light to reach earth from distant stars of which scientists say there are 200 billion. A British scientist and astronomer says there are 200 billion in a new book "The History of the Universe in 21 Stars."

After 5 years at 130,000 miles per hour, the NASA Juno spacecraft enters Jupiter's orbit. Jupiter is the largest planet in the solar system. An earlier spacecraft Galileo spent 8 years over Jupiter, but lacked the technology to survey the planet that Juno has. Information about Jupiter could reveal the origins of the solar system. A titanium valult protects Juno's critical systems from the volatile atmosphere around Jupiter. On the 37th orbit in Feb 2018 Juno will dive into Jupiter ending the mission but providing critical information on Jupiter.

Light in our galaxy The Milky Way travels at a speed of 300,000 kilometres a second so that light from the moon reaches us in less than 2 seconds. There are other distances we cannot even comprehend such as it taking thousands years for light to travel from distant stars in the Milky Way to earth. And even these distant stars have contributed to life on earth say scientists. During this strange pandemic where virus can mutate and can infect 18 million in the U.S. alone and about which so little is known, this idea of the planets and stars and time puts everything in perspective. Here DW.com talks to a British astronomer who studied at University College, London and Imperial College. Giles Sparrow is the author of "The History of the Universe in 21 Stars." Giles Sparrow tells us there are 200 billion stars, think of that for a moment!  Sparrow says 61 Cygni is an obscure star in the constellation of a swan. Astronomers with today's telescopes, itself something recent, have figured out the distance. Why are stars not shifting their positions as the earth moves around the sun? The reason is that stars are so far away we can only imagine these distances, or maybe not even able to imagine. ...
