Optimizing space travel efficiency
Sending a human into space and doing it efficiently presents a galaxy of challenges. Scientists have explored ways to integrate the logistics of space travel by looking at a campaign of lunar missions, spacecraft design, and conducting research, to create a framework to optimize fuel and other resources.

Meteorite diamonds tell of a lost planet
Scientists have examined a slice from a meteorite that contains large diamonds formed at high pressure. The study shows that the parent body from which the meteorite came was a planetary embryo of a size between Mercury to Mars.

Black hole and stellar winds form giant butterfly, shut down star formation in galaxy
Researchers have completed an unprecedented 'dissection' of twin galaxies in the final stages of merging. The new study explores a galaxy called NGC 6240. While most galaxies in the universe hold only one supermassive black hole at their center, NGC 6240 contains two -- and they're circling each other in the last steps before crashing together.

Martian moons model indicates formation following large impact
Scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant impact thought to have resulted in the Earth-moon system. Their work shows that an impact between proto-Mars and a dwarf-planet-sized object likely produced the two moons.

A 'Feel-Good Moment for Science': Volunteers Spot the Sun's Newest Neighbor
Citizen scientists have spotted a failed star, known as a brown dwarf, just 100 light-years from the sun.

Don't Let an Old Myth Prevent Your Child from Seeing the Solar Eclipse
Joe Rao's second book, "Looking Up!: The Science of Stargazing," debunks an old myth about solar eclipses and teaches kids (and parents) how to safely experience this amazing event.

Hubble gazes into a black hole of puzzling lightness
The beautiful spiral galaxy visible in the center of the image is known as RX J1140.1+0307, a galaxy in the Virgo constellation imaged by the NASA/ESA Hubble Space Telescope, and it presents an interesting puzzle. At first glance, this galaxy appears to be a normal spiral galaxy, much like the Milky Way, but first appearances can be deceptive!

French, US astronauts install batteries outside space station (Update)
French astronaut Thomas Pesquet floated into space on his first-ever spacewalk Friday, on a mission to help upgrade the power system outside the International Space Station with new, refrigerator-sized lithium-ion batteries.

Video: Huygens' descent to Titan
On December 25, 2004, the piggybacking Huygens probe was released from the 'mothership' Cassini spacecraft and it arrived at Titan on January 14, 2005. The probe began transmitting data to Cassini four minutes into its descent through Titan's murky atmosphere, snapping photos and taking data all the while. Then it touched down, the first time a probe had landed on an extraterrestrial world in the outer Solar System.

How old is our moon?
Most scientists agree that the Earth has pretty much always had its moon. Details of the moon's composition (in particular the "isotopic mixture" of heavier and lighter versions of various elements) are too similar to the Earth's for it to have been captured from somewhere remote. However, some compositional details differ enough to rule out the idea that the moon is simply a chunk of the Earth that broke loose.
