NASA’s Chandra and IXPE Capture Image of Shining Galaxy with Black Hole

The galaxy Centaurus A (Cen A) is a stunning sight to behold in this image, which combines data from multiple observatories. At the heart of this galaxy lies a supermassive black hole, which is currently feeding off the gas and dust that surrounds it. The black hole is also responsible for the large jets of high-energy particles and other material that are being spewed out into space. One of these jets can be seen at the upper left of the image, extending for an incredible 13,000 light-years away from the black hole.

Another fascinating feature of Cen A is the dust lane that wraps around the middle of the galaxy. This dust lane may have been caused by a collision with a smaller galaxy millions of years ago.

The colors in this image have been carefully chosen to reflect the sources of data. Blue represents X-ray light captured by NASA’s Chandra X-ray Observatory, while orange shows X-rays detected by NASA’s Imaging X-ray Polarimetry Explorer (IXPE) satellite. The white and gray areas represent optical light seen by the European Southern Observatory in Chile.

Scientists have been studying Cen A since the launch of Chandra in 1999, but with the recent launch of IXPE in 2021, they are able to explore this object in a whole new way. IXPE is specialized to look at a property of X-ray light called polarization, which relates to the organization of electromagnetic waves. This specialized measurement is helping scientists study how particles become accelerated to high energies and speeds at extreme cosmic objects like Cen A.

One of the key questions that researchers using IXPE hope to answer is what causes the X-ray emission in the jets. So far, they have not detected X-ray polarization at Cen A, which suggests that particles much heavier than electrons, such as protons, are not producing the X-rays. However, more insights are sure to come as scientists continue to analyze the data.

Cen A is located 12 million light-years from Earth in the constellation Centaurus and is the fifth brightest galaxy in the sky. Its stunning beauty and scientific mysteries continue to captivate astronomers and stargazers alike.
