![]() By using a three dimensional simulation, the team then found that the swirls could play a role in elevating the sun’s outer layer. The scientists went on to identify 14 solar super-tornadoes occurring within an hour of each other. The finding indicates that the solar tornadoes stretched through all three layers of the sun. While comparing images from the Swedish Solar Telescope with others taken by NASA’s Solar Dynamics Observatory, an international team of scientists noticed bright points on the sun’s surface and atmosphere that corresponded with swirls in the so-called chromospheres, a region that is sandwiched between the two layers. But a new study has found a possible answer: giant super-tornadoes on the sun that may be injecting heat into the outer layers of our star. Solar Tornadoes as Big as the US Heat Sun’s Atmosphereįor years, scientists have struggled to determine why the sun’s atmosphere is more than 300 times hotter than its surface. They orbit the sun among the rocky inner planets, as well as the gas giants that make up the outer planets. Meteoroids, especially the tiny particles called micrometeoroids, are extremely common throughout the solar system. And yet, Tyson says we are still “so blind to everything experts have been telling us.” Tyson points to The New Yorker cartoon by Frank Cotham in which one dinosaur says to another, “All I’m saying is now is the time to develop the technology to deflect an asteroid.”Īs Tyson points out, unlike the dinosaurs, “we can do something about it if people have the foresight to understand what the risks are, the dangers, and actually act upon it.” Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do. Unlike the dinosaurs, we have a space program. “I’m a little embarrassed for us,” Tyson tells Big Think. How different are humans from the dinosaurs that perished from the asteroid that hit the Yucatán peninsula? As Neil deGrasse Tyson points out in the video above, even if you are living on the other side of the planet from the site of impact, a big enough collision could “send a wave of extinction across the tree of life.” In all seriousness, if we don’t want to go the way of the dinosaurs, we need to wake up to the reality of this threat. That’s not a lot of lead time to build an arc or stock your apocalypse-proof shelter with Twinkies and ammo. After all, scientists have been warning the public for decades that we are not the safe small blue dot we like to think we are, but rather, we are more like a target in a “cosmic shooting gallery.”ĭid you know, for instance, that four small asteroids (although one was the size of a city block) just passed by us in the last week alone? Some of these asteroids were only discovered a few days before they buzzed by. is established to inform, encourage, and support the research activities of people who are interested in the field of. We all were, says astrophysicist Neil deGrasse Tyson, author of Space Chronicles: Facing the Ultimate Frontier. How could this meteor, the biggest to strike Earth since 1908, have gone undetected? Who was asleep at the switch? ![]() That is to say, the meteor created a shock wave that injured 1,200 people in the Chelyabinsk region of Russia, but the psychological shock was felt globally. The resulting explosion - estimated to have the strength of 25 Hiroshimas - woke a lot of people up. Early in the morning on February 15 a 55-foot meteor entered Earth’s atmosphere undetected.
