Coronal mass ejections may help us to understand what happened to the planet over billions of years." In the past, we think that Mars had a much thicker atmosphere. Notsu said, "The atmosphere of present-day Mars is very thin compared to Earth's. They think that gigantic coronal mass ejections may have played a large role in shaping planets like Earth and Mars into what we see today. Researchers note that huge mass ejections could have been much more common in the early years of the solar system. But until recently, that was just conjecture." So we suspect that they would also produce much bigger mass ejections. Notsu stated, "Superflares are much bigger than the flares that we see from the sun. Even so, the eruption from the distant star caught the attention of Notsu and the rest of the team making them wonder if such an eruption could lead to an equally super coronal mass ejection. Notsu explained that a superflare like that captured from EK Draconis could also happen on Earth's sun, but the possibility is rare occurring perhaps once every several thousand years. This would more than likely cause mass hysteria here on Earth. Yuta Notsu of the University of Colorado Boulder said, "Coronal mass ejections can have a serious impact on Earth and human society." If one of these mass ejections were to make a direct impact with Earth it could fry satellites in orbit and knock out the power grids to entire cities. They consist of clouds of extremely hot particles known as plasma that can travel through space at breakneck speeds of millions of miles per hour. Solar storms happen on a regular basis on our own Sun. So, when astronomers witness a coronal mass ejection, sometimes called a solar storm, being emitted from a younger star than our own, eyes and ears perk up. These particles are considered to be the Sun's most dangerous form of radiation. NASA wants to know this information because of the possibility of SEPs passing through a spacecraft causing damage to electronics, and even an astronaut's skin with the possibility of changing their DNA. One of those was the UVSC Pathfinder whose mission will be to study the origins of solar energetic particles (SEPs) in order to be able to better predict when they may occur. On December 7, NASA launched two new pieces of technology aboard the Atlas V rocket. The star is located dozens of lightyears from Earth, but it gives scientists a better idea of what is possible from our own Sun. Astronomers watched as star EK Draconis ejected a massive burst of energy more powerful than anything scientists have viewed in our own solar system.
