How Do Planets Get Their Names? We Asked a NASA Expert
How do planets get their names? With the exception of Earth, the planets in our solar system were named after Greek or Roman gods. Today, the job of naming things in space falls to the International Astronomical Union (IAU), the internationally recognized authority for naming celestial bodies and their surface features. NASA scientist Dr. Henry Throop explains more.

Science Launching on SpaceX's 28th Cargo Resupply Mission to the Space Station
The 28th SpaceX commercial resupply mission to the International Space Station (CRS-28) is scheduled to launch from NASA’s Kennedy Space Center in Florida this June.
The scientific experiments and technology demonstrations carried by the Dragon spacecraft include studies of how plants adapt to stress, measurements of genetic structures called telomeres, and satellite projects designed by students in Canada
Do Robots Help Humans in Space? We Asked a NASA Technologist
When it comes to space, humans and robots go way back. We rely heavily on our mechanical friends to perform tasks that are too dangerous, difficult, or out of reach for us humans. We’re even working on a new generation of robots that will help us explore in advanced and novel ways.

NASA | Massive Black Hole Shreds Passing Star
This artist’s rendering illustrates new findings about a star shredded by a black hole. When a star wanders too close to a black hole, intense tidal forces rip the star apart. In these events, called “tidal disruptions,” some of the stellar debris is flung outward at high speed while the rest falls toward the black hole. This causes a distinct X-ray flare that can last for a few years. NASA’s Chandra X-ray Observatory, Swift Gamma-ray Burst Explorer, and ESA/NASA’s XMM-Newton collected different pieces of this astronomical puzzle in a tidal disruption event called ASASSN-14li, which was found in an optical search by the All-Sky Automated Survey for Supernovae (ASAS-SN) in November 2014. The event occurred near a supermassive black hole estimated to weigh a few million times the mass of the sun in the center of PGC 043234, a galaxy that lies about 290 million light-years away. Astronomers hope to find more events like ASASSN-14li to test theoretical models about how black holes affect their environments.
