We journey from the very tiny in the form of a single molecule to the very large with clouds on Neptune and everything in between. Plus a bonus comic to round out the week!
Rosetta’s OSIRIS narrow-angle camera captured this image of Comet 67P/Churyumov-Gerasimenko on September 30, 2016, from an altitude of about 16 km above the surface during the spacecraft’s final descent. The image scale is about 30 cm/pixel and the image measures about 614 m across.
And now for something a "little" different. This is an actual picture of a molecule taken by IBM in 2009! The ringed structure is about 500,000 times thinner than a human hair – and you may recognize its shape. The molecule is pentacene, which consists of 22 carbon atoms and 14 hydrogen.
This Voyager 2 high-resolution color image, taken two hours before the spacecraft's closest approach to Neptune, provides evidence of vertical relief in Neptune's bright cloud streaks. The sides of the clouds that face the Sun are brighter than the surrounding cloud deck because they are more directly exposed to sunlight. Shadows can be seen on the side opposite the Sun. Cloud heights appear to be of the order of 50 kilometers.
Enjoy some humor as we head into a holiday weekend here in the U.S.!
Text: NASA successfully hurled an object into an asteroid at 14,000 mph to see if it could be knocked off course. The James Webb telescope took a detailed image of the impact site.

Scientists are getting closer in their search for life beyond earth. But with limited federal funding for the search for extraterrestrial intelligence, supporters are the reason cutting-edge scientists can keep their eyes on the sky.
