    See an awesome 3D map of the massive cosmic bubble surrounding Earth

    Illustration of a local bubble artist with star formation on the surface of the bubble. Scientists say that because of this bubble, there are all young stars within 500 light-years of the Sun and Earth.

    Once upon a time in the history of the galaxy, clusters exploded to form fantastic supernovae. The blast was so strong that glittering remnants pushed the shroud around the interstellar gas outwards, drifting into the bubbles of the universe 1,000 light-years wide. As you read this, it’s a huge chunk that is still growing.

    By coincidence, experts say our own sun flew directly into this bubble. Now we are living a smack in the middle of it, giving it a suitable name for a small ball, a local bubble.And in the dissertation Published in the journal Nature on Wednesday, Scientists use 3D maps of huge structures to provide novel details of the bubble story.

    Most surprisingly, they found it to be the main reason we have a strangely rich young star neighborhood.

    “This is really a story of origin. For the first time, I can explain how all the nearby star formations began,” said Harvard University and the Smithsonian Astrophysics Center’s former astronomer and data visualization expert. , The author of the study, Catherine Zucker Said in a statement.

    Astronomers usually study the seven spots in the universe where stars appear to form most often. Zucker’s research found that each sits on the surface of a local bubble. The team believes that the same starry bubbles that surround us will appear throughout the universe, but we believe that it is very rare for us to be directly in the middle of it.

    The concept is comparable to the dough of the universe, which resembles perforated Swiss cheese, with each hole representing the center of star formation. For some reason, we are in one of the cheesy holes. Our homestars have stores in local bubbles, so every time we look into the sky, we witness the birth of many stars.

    Beyond that stellar contingency, a great 3D animation of a team of local bubbles- You can play here -Light up the evolution of structure.

    For example, researchers have calculated that about 15 supernovae are responsible for the occurrence of blobs that occurred about 14 million years ago. The sun appears to have entered the orb about 5 million years ago, and the bubbles seem to coast at about 4 miles per second (6.5 kilometers). “It lost most of its vitality … and was quite stagnant in terms of speed,” Zucker said.

    Alyssa Goodman, an astronomer and research author at Harvard University and the Smithsonian Astrophysics Center, called the team’s findings “an incredible detective story based on both data and theory.”Goodman is also the founder of seaweed, Data visualization software that enables discovery.

    In the future, researchers hope to continue to uncover the secrets of interstellar bubbles, such as local bubbles, by applying software to 3D map things deeper in the universe. ..

    “You can use a variety of independent clues, such as supernova models, stellar movements, and exquisite new 3D maps of the material surrounding local bubbles, to stitch together the history of star formation around them,” Goodman said. I am.

    Zucker wonders, “Where do these bubbles come in contact? How do they interact? How do superbubbles promote the birth of sun-like stars in the river of heaven?” ..
