And, In a Refinement Of Our 2019 Reporting -- Sagittarius A BlackHole, Imaged Anew...


We had originally mentioned this first ever real live image of Sag A* -- in April of 2019 (having learned of the project in early April of 2017). Since then, it has been re-released, and greatly refined -- with additional processing. So I won't spoil the beauty of it, with a pic here -- go look at the linked article below.

But it all very-visually confirms what each of the mathematical models of black holes predicted would be the visible wavelength appearance of such a beast.

So we run both our original graphic and a small .gif, that is likely very accurate (as confirmed by this ground-breaking in-situ data, of the heart of our own Milky Way). Accurate to what we would witness, that is, should we ever get within a few light years of a smaller black hole, in person.

Here's that story, courtesy of our flawless Anon. contributor:

. . .For the first time, humanity has stared into the dark heart of unfathomable chaos at the center of the Milky Way and brought its shadowy form into focus. The object staring back at us, Sagittarius A*, is a monstrous black hole that binds our home galaxy together.

On Thursday, scientists with the Event Horizon Telescope (EHT) Collaboration revealed the first direct visual evidence of Sagittarius A*, or Sgr A*, in coordinated worldwide press conferences. Composed of over 300 researchers, the collaboration made headlines three years ago for unveiling the first image of any black hole and has been attempting to image Sgr A* since 2009. . . .

This dazzling light, swirling orange around a shadowy circle, traveled more than 26,000 years to reach us. It is of luminescence birthed at the edge of Sgr A* when Earth's northern ice sheets reached as far as Manhattan, cave bears still roamed Europe and Homo sapiens settlements were being built from mammoth bones. . . .


Now you know. . . with various spectral visitors appearing, from all over the globe, of late. . . so, we may seem more than a little distracted here. Smile. Have a wonderful weekend, one and all. . . time to take a long ride by the lake -- very warm and sunny here.

With one more throwback explainer graphic below, now:

A) beautiful and impressive graphic
B) and space week continues to thrill: https://www.msn.com/en-us/news/technology/nasas-mars-helicopter-was-supposed-to-fly-five-times-its-flown-28/ar-AAXeq0V?li=BBnb7Kz

Hey now -- thanks. And. . . me? I am still waiting for NASA | JPL to catch one last flight of the chopper, at sunset. . . when we might see it aglow, with. . .

St. Elmo's Fire. . . .

I do love that it has lasted 28 flights (~8 X its planned mission duration), already. . . and may it wake, when Martian Spring winds return!

Great stuff -- Namaste. . . .
