![]() ![]() "We were able to figure out how much momentum is currently in the Local Bubble's expanding surface and compare it to how much momentum must have been injected by the supernovae to power its expansion," Zucker said. ![]() The observations also allowed the researchers to work out how fast the cosmic void is expanding, which is currently around 4 miles per second (6.4 kilometers per second), according to a statement by researchers. The researchers used data obtained by the European Space Agency's Gaia space observatory to create a 3D map of the Local Bubble's surface and to calculate the trajectory of the seven main star-forming regions that make up the "skin" of the bubble. The shock wave continues to push the surface outward, causing the bubble to expand. "Powerful supernova explosions triggered an expanding shock wave, sweeping up interstellar clouds of gas and dust into a dense shell that now forms the surface of the Local Bubble," Zucker said. Instead, it is more like a lumpy blob created by multiple supernovas. The Local Bubble is not a uniform sphere, because it was not formed by a single explosion. This allowed the team to work out exactly how many supernovas were needed to carve out the gigantic cosmic void and better understand how star-forming regions are created across the Milky Way. 12 in the journal Nature, researchers accurately mapped the star-forming regions surrounding the Local Bubble and, in doing so, calculated how fast the superbubble is expanding. Those stellar explosions, the researchers said, would have blasted the materials needed to make new stars, such as hydrogen gas, to the edge of a huge area in space, leaving behind the Local Bubble that's surrounded by a frenzy of star births. This setup had suggested that several supernovas were responsible for this void. The only stars inside the bubble either existed before the bubble emerged or formed outside the void and are now passing through the sun is one such trespasser.
