Threads of superheated gas and magnetic fields are weaving a tapestry of energy at the center of the Milky Way galaxy. A new image of this new cosmic masterpiece was made using a giant mosaic of data from NASA’s Chandra X-ray Observatory and the MeerKAT radio telescope in South Africa.<\/p>\n

The new panorama of the Galactic Center builds on previous surveys from Chandra and other telescopes. This latest version expands Chandra’s high-energy view farther above and below the plane of the Galaxy\u2014that is, the disk where most of the Galaxy’s stars reside\u2014than previous imaging campaigns. In the image featured in our main graphic, X-rays from Chandra are orange, green, blue and purple, showing different X-ray energies, and the radio data from MeerKAT are shown in lilac and gray. The main features in the image are shown in a labeled version.<\/p>\n

One thread is particularly intriguing because it has X-ray and radio emission intertwined. It points perpendicular to the plane of the galaxy and is about 20 light-years long but only one-hundredth that size in width.<\/p>\n

A new study of the X-ray and radio properties of this thread by Q. Daniel Wang of the University of Massachusetts at Amherst suggests these features are bound together by thin strip<\/a>s of magnetic fields. This is similar to what was observed in a previously studied thread. (Both threads are labeled in the image. The newly studied one is in the lower left and is much farther away from the plane of the Galaxy.) Such strips may have formed when magnetic fields aligned in different directions, collided, and became twisted around each other in a process called magnetic reconnection. This is similar to the phenomenon that drives energetic particles away from the Sun and is responsible for the space weather that sometimes affects Earth.<\/p>\n
