An inspired biographical picture book about a female astronomer who makes huge discoveries about the mysteries of the night sky and changed the way we look at the universe Vera Rubin was one of the astronomers who discovered and named dark matter, the thing that keeps the universe hanging together. Throughout her career she was never taken seriously as a scientist because she was one of the only female astronomers at that time, but she didn't let that stop her. She made groundbreaking and incredibly significant discoveries that scientists have only recently been able to really appreciate--and she changed the way that we look at the universe. A stunning portrait of a little-known trailblazer, The Stuff Between the Stars tells Vera's story and inspires the youngest readers who are just starting to look up at the stars.

"A well-illustrated overview of the science and (literal) impact of these space rocks." -- Science News, on the first edition Leading experts in the field provide a compelling introduction to the space rocks that enter Earth's atmosphere at speeds ranging from 25,000 mph to 160,000 mph. Scientists estimate that about 48.5 tons of meteoritic material falls on the Earth each day. These messengers from space give us a unique insight into the nature of the material that was present when our solar system formed. Many of the specimen meteorites in this second edition were re-photographed to improve quality, and the optical microscopy shots were updated. There is also much new information on discoveries and developments in the study of meteorites, including: Meteorite falls and craters, and new information on ones previously covered Use of weather radar to detect and analyze meteorites, such as the 28,000 mph January 18, 2018, Michigan "fireball" How astrophysicists determine if a meteorite comes from Mars, and information about the Martian meteorites found to date Updated information on the results of the European Space Agency's Rosetta Mission in which a controlled impact was successfully completed into Comet 67P after investigating it with a probe for more than two years. Co-author Sara Russell, who is part of NASA's Mars program, provides the latest news about NASA's Mars programs, including the Mars Rover, which landed in 2016.
