Presentation in the Science Circle May 18,2019. First Image of a supermassive Black Hole

First Image of a supermassive Black Hole
 From abstract in website
“Staring into the abyss: the first image of a supermassive black hole”
On April 10 of this year, the Event Horizon Telescope team released a radio image of the black hole at the core of the galaxy M87. The image is a ring of light, brighter on one side. What does it mean? What does it tell us about the black hole? Why are people so excited about it?
In this talk, I’ll discuss what black holes we know are out there, including supermassive black holes like this one. I’ll talk what it really means to take a picture of something that no light escapes from, and I’ll talk about how the image we see is just as much affected by the gravity of the black hole as it is by the plasma that actually emitted the light we’re looking at.

  In talking about resolution, Rob is setting us up for how the Event Horizon Telescope, with its eight telescopes synchronized across five continents, effectively creates an aperture the size of the whole Earth! So it has a resolution high enough to see details around a supermassive black hole in M87!

May 12 is the Mother's Day 2019

Mother's Day is a celebration honoring the mother of the family, as well as motherhood, maternal bonds, and the influence of mothers in society. It is celebrated on various days in many parts of the world, most commonly in the months of March or May.
While the United States holiday was adopted by some other countries, existing celebrations, held on different dates, honouring motherhood have become described as "Mother's Day", such as Mothering Sunday in the United Kingdomor, in Greece, the Eastern Orthodox celebration of the presentation of Jesus Christ to the temple (2 February of Julian Calendar). Both the secular and religious Mother Day are present in Greece Mothering Sunday is often referred to as "Mother's Day" even though it is an unrelated celebration.
