“[T]he earliest image indicates that it was roughly 100,000 Kelvin, which
suggests we were looking at it just six hours after it exploded. The latest
lensed image shows that the debris had already cooled to 10,000 K over the
eight days between the two different images.”

“Knowing that these two impacts generated events allowed for a direct comparison
between the estimates and the impact location. And it turns out the estimates
are quite good. One event was estimated at 3,530 ± 360 km away,
and it turned out to be 3,460 km from the lander, a difference of just
70 km.”

“Kodak slowly began to fix this bias in its film, but not out of any sense of
racial injustice: it was a response to complaints from furniture makers and
chocolate sellers that Kodak cameras couldn’t properly capture their products’
hues.”

“There are some who take organic chemistry to get into a Ph.D. program or
prepare for a career in chemistry, but they’re relatively rare. Most of the
students are pre-med, and for a lot of them, organic chemistry is a
dream-shattering experience.”
It seems to me like the professor at the center of this story was done a grave
disservice by NYU , set up to fail
(though surely not intentionally on anybody’s part) and then abandoned.

“[I]n this case, the unseen companion was producing copious amounts of radiation
that was heating the star. This process essentially produces a star with a
‘daytime’ side bathed in radiation, so it’s more energetic and brighter, and a
‘nighttime’ side that emits the star’s intrinsic brightness.”
