Approximately 4.6 billion years ago, our solar system was a cloud of dust and gas known as the solar nebula. As gravity caused the material to collapse in on itself, it spun faster and faster and eventually flattened into a disk. Researchers believe that most of the material accumulated in the center, to form the sun, while the rest clumped together, creating protoplanets – balls of gas, dust, and rocks, about the size of Mercury or Mars. Over the years, some of the protoplanets collided to form our eight planets, while the rest continue to whirl around the sun as asteroids or rocky debris. However, the one thing scientists are not sure is the process by which the planets came together. Now, a 4.565 billion-year-old space rock, the oldest igneous meteorite ever discovered, may provide clues to this age-old mystery....

While elite athletes like Simone Biles and McKayla Maroney make it look easy, gymnastics is one of the hardest sports on the planet – both physically and mentally. It is, therefore, not surprising to hear that most gymnasts retire in their late teens or early 20’s. But don’t tell that to Oksana Chusovitina. The veteran gymnast, who has been in the limelight since winning her first major competition – the USSR’s junior national championships – at age 13, is still going strong at the ripe “old” age of 43!...

Even if an art museum featuring portraits of legendary singer Frank Sinatra and Hollywood icon Marilyn Monroe is not your idea of fun, you may want to give Candytopia a chance. That’s because, in this museum, everything is made from candy! The best part? There is no need to find a “Golden Ticket” to gain admission to this real-life Willy Wonka world that is making its way around the US — tickets can be purchased online, or in-person at the venue....

NASA’s ambitious mission to “touch” the Sun got underway at 3:31 a.m. EST on August 12 with the launch of the Parker Solar Probe from Cape Canaveral, Florida. Within six weeks, the spacecraft, which is currently traveling at 39,500 miles per hour, will conduct the first of seven flybys of Venus and use the planet’s gravitational pull to catapult itself closer to the Sun. The process, known as gravity assist, is instrumental in the probe’s mission to reach our fiery star....

The most noticeable difference between the modern human face and that of the hunter-gatherers, who lived on Earth over 200,000 years ago, is the forehead. While we now have flat, smooth foreheads with visible eyebrows, our ancestors sported a pronounced brow ridge. Experts have always believed that the thick rim, and the evolution to the beautiful tufts of facial hair, served a physiological function. Now, a team of scientists from UK’s University of York and Portugal’s Universidade do Algarve suggest the distinct facial features help with our social relationships....

Researchers have always maintained that Triassic dinosaurs were small, chicken-sized critters, and that it was not until the Jurassic period — about 180-million years ago — that massive herbivorous sauropods, like the Diplodocus and Brachiosaurus, emerged. However, the discovery of a new dinosaur species in Argentina suggests that the animals achieved gigantism during the late Triassic period, about 30 million years earlier than previously believed....

Large predators are increasingly appearing in unexpected places — alligators in saltwater marshes, killer whales in rivers, and mountain lions far away from the closest mountain. Experts hypothesize that as successful conservation efforts increase the local populations of these predators, they are moving beyond their usual habitats in search of food. However, Brian Silliman, professor of marine conservation biology at Duke University has a different theory. He believes the animals are recolonizing habitats they lived and hunted in for centuries — before human activity pushed them to the brink of extinction, and long before researchers began studying them....

Archeologists had always assumed that our early ancestors began baking about 10,000 years ago, after they gave up their nomadic way of life and became farmers. The scientists hypothesized that the abundant grain harvests inspired ancient humans to mill the crop into flour and make bread. However, the discovery of the charred remains of a flatbread that dates back over 14,000 years seems to indicate humans began baking long before their transition to an agricultural-based life....

Every now and again, Mother Nature reveals a delightful surprise in the form of something unusual and remarkable. One such extraordinary occurrence is the recent discovery of an extremely rare hybrid between a melon-headed whale and a rough-toothed dolphin. The mammal was first sighted in August 2017 by a group of researchers on a two-week expedition to document marine life off the coast of Kauai, Hawaii....
