THE BRIGHTEST OBJECT IN THE SKY

Today, no politics, no wars, no Trump.  All space science, for astronomers found what may be the Universe's brightest object in the sky,  J0529-4351 , and it's humongous. Out there 12 billion light-years away is a quasar with a black hole at its heart, growing so fast that it swallows the equivalent of a Sun a day. A light-year is 5.8 trillion miles. From your early science courses you must remember that the Sun is 92 million miles from us. A light year ( which is a unit of length ) is equivalent to doing 31,500 round trips to the sun. Thus, you would need to do that 12 billion times to get to J0529-4351. This quasar shines 500 trillion times brighter than our Sun.   That black hole powering that quasar is more than 17 billion times more immense than our Sun.  But there are bigger ones, for at the center of the galaxy cluster Abell 1201 is a black hole equivalent to 30 billion Suns. This is the most violent place in our Universe. Age?  Began to form not long after the Big Bang.

HOW LONG DOES IT TAKE TO RENEW A PASSPORT?

Yesterday I brought you up to date on our current COVID-19 pandemic.  As much as this virus is waning, what about the combined impact this Fall and Winter when you add the seasonal flu and that Respiratory Syncytial Virus ( RSV ) that infects mostly children and infants?  Is a  TRIPLEDEMIC  coming? About world news, from the  New York Times  this morning: Boris Johnson   pulled out of the race   to become Britain’s prime minister, making his former finance minister, Rishi Sunak, the next PM. Xi Jinping, China’s leader, appointed loyalists to top government jobs,   giving him nearly absolute power .  Will he be president for life? A   solar eclipse will be visible tomorrow   across Europe and Asia. U.S. students recorded   deep declines in math and a dip in reading   on a national exam, the clearest picture yet of the pandemic’s impact on education. The World Series is set to begin on Friday:   Both the   Astros   and   Phillies   clinched spots yesterday, setting up a battle between ju
