This picture, taken by Hubble’s Advanced Camera for Surveys, shows NGC 4696, the largest galaxy in the Centaurus Cluster. (To see a video of NGC 4696 go here: <a href="http://www.flickr.com/photos/gsfc/4888176841/)">www.flickr.com/photos/gsfc/4888176841/)</a> The huge dust lane, around 30 000 light-years across, that sweeps across the face of the galaxy makes NGC 4696 look different from most other elliptical galaxies. Viewed at certain wavelengths, strange thin filaments of ionised hydrogen are visible within it. In this picture, these structures are visible as a subtle marbling effect across the galaxy’s bright centre.

Oddly enough, an elongated coronal hole (the darker area near the center) seems to shape itself into a single, recognizable question mark over the period of one day (Dec. 21-22, 2017). Coronal holes are areas of open magnetic field that appear darker in extreme ultraviolet light, as is seen here. These holes are the source of streaming plasma that we call solar wind. While this exercise is akin to seeing shapes in clouds, it is fun to consider what the sun might be asking? Perhaps what the new year will bring? Guess what I am going to do next?

KENNEDY SPACE CENTER, FLA. -- Space shuttle Atlantis STS-122 Commander Steve Frick responds to a question from the media during a press conference at the slidewire basket landing on Launch Pad 39A. The STS-122 crew is at NASA's Kennedy Space Center to take part in terminal countdown demonstration test, or TCDT, activities, a standard part of launch preparations. The TCDT provides astronauts and ground crews with equipment familiarization, emergency egress training and a simulated launch countdown. On mission STS-122, Atlantis will deliver the European Space Agency's Columbus module to the International Space Station. Columbus is a multifunctional, pressurized laboratory that will be permanently attached to U.S. Node 2, called Harmony, and will expand the research facilities aboard the station. Launch is targeted for Dec. 6. Photo credit: NASA/Kim Shiflett

What's up and what's down? This image covers mesas, or high-standing plateaus, to the north and pits, or low-standing, depressions to the south. If it looks the other way around, then you are not seeing the topography correctly. Remember that the Sun is coming from the left (west) at MRO's imaging time of about 3 p.m. What formed these mesas and pits is a question that is not so easy to answer. http://photojournal.jpl.nasa.gov/catalog/PIA20812
