Asteroid Discovery From 1980 - 2010

Video Created by Scott Manley, this is a view of the solar system showing the locations of all the asteroids starting in 1980, as asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones. The final colour of an asteroids indicates how closely it comes to the inner solar system. Earth Crossers are Red Earth Approachers (Perihelion less than 1.3AU) are Yellow All Others are Green Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You’ll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video. As the video moves into the mid 1990′s we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you’ll see a region of high discovery rates aligned in this manner. At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that’s tasked with imaging the entire sky in infrared wavelengths. The scale of the video at 1080P resolution is roughly 1million kilometers per pixel, and each …

In the 50 years since US insurers organized the Insurance Institute for Highway Safety, car crashworthiness has improved. Demonstrating this was a crash test conducted on Sept. 9 between a 1959 Chevrolet Bel Air and a 2009 Chevrolet Malibu. In a real-world collision similar to this test, occupants of the new model would fare much better than in the vintage Chevy. “It was night and day, the difference in occupant protection,” says Institute president Adrian Lund. What this test shows is that automakers don’t build cars like they used to. They build them better.” The crash test was conducted at an event to celebrate the contributions of auto insurers to highway safety progress over 50 years. Beginning with the Institute’s 1959 founding, insurers have maintained the resolve, articulated in the 1950s, to “conduct, sponsor, and encourage programs designed to aid in the conservation and preservation of life and property from the hazards of highway accidents.” A decade after the Institute was founded, insurers directed this organization to begin collecting data on crashes and the cost of repairing vehicles damaged in crashes. To lead this work and the Institute’s expanded research program, insurers named a new president, William Haddon Jr., who already was a pioneer in the field of highway safety. In welcoming Dr. Haddon, Thomas Morrill of State Farm said “the ability to bring unbiased scientific data to the table is extremely valuable.” This scientific approach, ushered in by …
