lots of interesting details regarding the analemmas of other planets, the contributions of the two factors that go into the Equation of Time, why some analemmas are figure-8s while some aren't, and the supposed "moon analemmas" that have appeared on the Astronomy Picture of the Day. I...

However, non-detections of Ti and TiO at the day–night terminator of WASP-121b complicate this picture13,14,15,16, as these gases should also form condensates such as perovskite and TiO2 on the nightside27,28,29. It would be surprising if Ti-bearing condensates are efficiently cold ...
Mazatlan on eclipse day, but totality didn’t end until 11:11am local time. That’s about five hours after the sun first touched Mazatlan’s beaches. There was no possibility of taking a sunrise picture of the eclipse in Mexico on April 8, even though the country would have the foliage...

For people who can't make it on peak nights I always am asked what will the shower look like on nights either side of the peak. The Perseids has a very sharp peak on a single night of 100 meteors per hour. On nights off peak the rate quickly drops to 1/10th that, around 10 mete...
During these perturbations, the eccentricity of the Moon could have reached 0.2, and hence, the simple picture invoked by classic studies of the two-body Earth–Moon system may be invalid (and that there may have been epochs in Earth history during which the Moon rotated super-synchronously)....
