China’s Tianwen-1 Mars orbiter snaps fuzzy picture of interstellar comet 3I/Atlas
Chinese engineers have successfully taken a picture of interstellar comet 3I/Atlas as it passed its closest to point to Mars, about 19 million miles away, using their Tianwen-1 Mars orbiter.
The Tianwen-1 team began preparing for the observation in early September. After repeated simulations and feasibility assessments, they determined to use the high-resolution camera on the orbiter and designed optimal imaging strategies, ultimately achieving successful observation.
That image is to the right. Based on the fuzziness of the surrounding stars, the camera was not able to get a perfect focus during the observations. The main take-away is that the images once again prove 3I/Atlas is a comet not unlike those from our own solar system.
The mainstream press and some untrustworthy press-seeking scientists have tried to make a big deal about any interesting data point that has been observed from Comet 3I/Atlas, trying to claim it is some weird alien object of momentous importance. It is not. It is like every other solar system comet, though like those comets it is unique in its own way.
The big discovery here is how similar it is from solar system comets, suggesting that the processes that created our solar system are somewhat common throughout the galaxy.
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 print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

That image looks overprocessed. Stars should be sampled with several pixels per star-extent (“critically sampled”). This looks like someone thresholded the image to make the background black. The central object might be the only real one, with the rest being noise.
