Artist’s concept of a Bimodal Nuclear Thermal Rocket in Low Earth Orbit. Credit: NASA In the past four decades, NASA and other space agencies from around the world have accomplished some amazing feats.
Can you see the comet? Four solar system objects adjusted for true brightness counterclockwise from the upper right: Earth, Enceladus, the Moon, and Comet 67/P.
Toes of a pahoehoe flow of basaltic lava advance across a road in Kalapana from the Kilauea Volcano in Hawaii (left).
A fresh 1-km wide crater on Mars, captured by the HiRISE camera on the Mar Reconnaissance Orbiter. Or does it look like a mountain to you?
How would our horizon look if Earth orbited around another star, such as Alfa-Centauri, Sirius, or Polaris?
Are we seeing the convergence of a century of space science and science fiction before our eyes? Will Musk and SpaceX make 2001 Space Odyssey a reality?
Boeing and SpaceX are building private spaceships to resume launching US astronauts from US soil to the International Space Station in 2017.
A triple crater in Elysium Planitia on Mars. Credit: NASA/JPL/University of Arizona. At first glance, you many not guess that this feature on Mars is an impact crater.
Can documentary films actually change the way people think about a topic? Films like “The Thin Blue Line,” “The Triumph of Will,” and “Harlan County USA” are definitely documentaries that swayed both local public opinion and world views on specific topics.

When a star encounters a black hole, tidal forces stretch the star into an elongated blob before tearing it apart, as seen in these images from a computer simulation by James Guillochon of Harvard University.

NASA-NOAA Suomi NPP satellite captures blizzard near peak intensity as it moves over New York and Boston regions at 1:45 am EST, Jan.
Animation of Ceres made from images acquired by Dawn on Jan. 25, 2015. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA) This is the second animation from Dawn this year showing Ceres rotating, and at 43 pixels across the images are officially the best ever obtained!

An artist rendition of Kepler-444 planetary system, which hosts five planets, all smaller than Earth.

Credit: NASA/JPL-Caltech/UCAL/MPS/DLR/IDA I don’t think I ever learned one of those little rhymes – My Very Educated Mother Just Served Us Nine Pizzas – to memorize the order of the planets, but if I had, it would’ve painted for me a minimalist picture of the solar system.
Illustration by artist Ron Miller of the gigantic ring system around J1407b. (© Ron Miller. Used with permission.) Astronomers watching the repeated and drawn-out dimming of a relatively nearby Sun-like star have interpreted their observations to indicate an eclipse by a gigantic exoplanet’s complex ring system, similar to Saturn’s except much, much bigger. What’s more, apparent gaps and varying densities of the rings imply the presence of at least one large exomoon, and perhaps even more in the process of formation!
