First sunspot image from Inouye Solar Telescope
Click for full image.
The science team for the new Inouye Solar Telescope, now in the final phase of construction, has released the telescope’s first high resolution sunspot image.
The image is to the right, reduced to post here, and was taken almost a year ago, on January 28, 2020.
“The sunspot image achieves a spatial resolution about 2.5 times higher than ever previously achieved, showing magnetic structures as small as 20 kilometers on the surface of the sun,” said [Dr. Thomas Rimmele, the associate director at NSF’s National Solar Observatory (NSO)].
The image reveals striking details of the sunspot’s structure as seen at the Sun’s surface. The streaky appearance of hot and cool gas spidering out from the darker center is the result of sculpting by a convergence of intense magnetic fields and hot gasses boiling up from below.
…This sunspot image, measuring about 10,000 miles across, is just a tiny part of the Sun. However, the sunspot is large enough that Earth could comfortably fit inside.
The start of official telescope operations is set to begin in ’21, and had been delayed because of the Wuhan flu panic. Construction had begun in ’13.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Breath-taking imagery.
Remember reading a National Geographic about the Sun (want to say late 60’s; cursory search didn’t yield results) where I was first exposed the ‘granularity’ of the Sun’s, and presumably, other star’s, surfaces. For me, a revelation.
Perhaps we will revert to the time of monks in (scientific) monasteries.
This somehow feels appropriate for this post:
