9 Billion-Year-Old Radio Signal

"I barely understand half of this article but, wow . . ."

Scientists have discovered a crucial radio signal known as the 21-centimeter line, which is the key to unlocking many cosmic mysteries, in the most distant galaxy yet, reports a new study. 

Previously, this type of signal had only been spotted in galaxies within a few billion light years of Earth, but the new detection hailed from a galaxy that existed nearly nine billion years ago, when the universe was about a third of its current age. Scientists were only able to spot the signal because a natural telescope created by another celestial body, called a gravitational lens, magnified it 30 times over, providing an unprecedented glimpse of processes in the early universe.

The Peace of Christmas

I recognize that everyone reading this is may not be a Christian, and even all Christians may not view the gospels the way I do. But this Christmas, I think it’s appropriate to look to the story of Jesus’ birth with at least curiosity, whether one is a believer or not.

I think it's almost impossible to read the Christmas story and not see the value of peace. Our culture is good at many things, but creating periods of quiet is not one of them. We have long to-do lists, wait impatiently in traffic, struggle to keep our heads above water, and struggle to find hope in our political leaders as we are faced with almost insurmountable challenges. 

There is a painting that I have always admired, which hangs in the National Gallery in London. It was painted in the 1620s by Philippe de Champaigne and is titled “The Dream of St. Joseph.” Joseph and Mary are shown at home during Mary’s pregnancy with Jesus. Joseph has come home from work at the end of a long day and is asleep on a chair, with his carpentry tools and sandals strewn at his feet. It’s a simple room, with a rough rug under his feet. Mary, awake and sitting at a table in the background, watches as an angel flies over Joseph to deliver a message: that he should not dismiss Mary because of her pregnancy. It’s not a scene of trumpet-blaring glory, but a humble and important moment. Deep wisdom comes in the quiet times.
