3. Necklace Nebula

(The "Necklace Nebula", also called PN G054.2-03.4, is the exploded aftermath of a giant star that came too close to its Sun-like binary companion. The two stars that produced the Necklace Nebula live in a relatively small orbit about each other. They have a period of 1.2 days and a separation on the order of 5 times the radius of the Sun. )

5. Neanderthal Hand Axe

(This Mousterian hand axe was primarily used as a butchering tool, though likely came in handy for other purposes as well. It was shaped from a jasper chert and was found in France before making its way into Educated Earth's collection.)

6. Transporting 60 People

(This poster hangs in the Planning Office in the city of Munster, Germany. It very graphically demonstrates the need for an effective transit strategy by showing how much space it takes to move 60 people via cars, buses, and bicycles.)

9. Celestial Snow Angel

(Just in time for the holidays, the Hubble Space Telescope has snapped a spectacular view of a star-forming region in our Milky Way galaxy that looks like a snow angel in deep space. A newly-formed star called S106 IR is shrouded in dust at the center of the image, and is responsible for the surrounding gas cloud’s hourglass-like shape and the turbulence visible within. Light from glowing hydrogen is colored blue in this image. )

10. Twin Linear Aerospike XRS-2200 Engine

(The test of twin Linear Aerospike XRS-2200 engines, originally built for the X-33 program, was performed on August 6, 2001 at NASA's Stennis Space Center, Mississippi. The engines were fired for the planned 90 seconds and reached a planned maximum power of 85 percent. NASA's Second Generation Reusable Launch Vehicle Program , also known as the Space Launch Initiative (SLI), is making advances in propulsion technology with this third and final successful engine hot fire, designed to test electro-mechanical actuators. Information learned from this hot fire test series about new electro-mechanical actuator technology, which controls the flow of propellants in rocket engines, could provide key advancements for the propulsion systems for future spacecraft. The Second Generation Reusable Launch Vehicle Program, led by NASA's Marshall Space Flight Center in Huntsville, Alabama, is a technology development program designed to increase safety and reliability while reducing costs for space travel. The X-33 program was cancelled in March 2001.)
