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.
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 — that is, the disk where most of the Galaxy's stars reside — than 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.
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.
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 strips of magnetic fields. This is similar to what was observed in a previously studied thread. (Both threads are labeled with red rectangles in the image. The newly studied one in the lower left, G0.17-0.41, 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.
A detailed study of these threads teaches us more about the Galactic space weather astronomers have witnessed throughout the region. This weather is driven by volatile phenomena such as supernova explosions, close-quartered stars blowing off hot gas, and outbursts of matter from regions near Sagittarius A*, our Galaxy's supermassive black hole.

Public domain masterpieces
The mission of this series is to promote space and science. The creators want these designs to hang on your wall, which is in line with our mission in Astrography. That is why we decided to use our competence in printing cosmos inspired graphics and photos to provide you with these projects in the highest possible quality on Fine Art (Giclée) pigments and papers.
These projects are available in the public domain. You can download them from NASA website and print them at any printing house. but we are convinced that thanks to our experience in printing space photographs we are able to provide the best quality of these posters in the world. We do not earn on copyright here. In this series, we provide specializing printing competences & technologies (dedicated in space), packaging and worldwide logistics. Let the promotion of science and art become a common fashion.
Posters will look great in your home, children’s room, or office.
