Nasa’s Chandra X-ray Observatory has captured a breathtaking view of 30 Doradus B, a remnant of a supernova within a lively cosmic region where stars have been forming for millions of years.
This extraordinary display, situated in the Large Magellanic Cloud approximately 160,000 light-years away from Earth, illustrates the dramatic and captivating life cycles of stars.
The composite image, composed of various light wavelengths, unveils the intricate details of 30 Dor B. Purple hues represent X-ray data from Chandra, while orange and cyan depict optical observations from the Blanco 4-meter telescope in Chile. Red hues signify infrared data from Nasa’s Spitzer Space Telescope, and the Hubble Space Telescope contributes black and white optical data, highlighting the remnant’s sharp features.
Astronomers, led by Wei-An Chen of National Taiwan University, have dedicated more than two million seconds of Chandra’s observation time to analyze this celestial phenomenon.
Their investigation revealed a faint X-ray shell extending approximately 130 light-years, containing particle winds propelled by a pulsar, forming what is known as a pulsar wind nebula.
The team’s analysis suggests that the intricate structure of 30 Dor B is unlikely the outcome of a solitary supernova event. The intense X-rays at the center and the pulsar likely resulted from the explosion of a massive star around 5,000 years ago.
However, the expansive shell of fainter X-rays implies that another supernova occurred more than 5,000 years earlier, and possibly additional events before that.
This discovery offers astronomers valuable insights into the life and death of massive stars and the consequences of their explosive conclusions. The detailed findings, published in the Astronomical Journal, emphasize the dynamic nature of our universe and the continuous processes shaping it.
The image itself is a vibrant display of color and texture, with clouds of gas resembling cotton candy and thick syrup, set against a backdrop of radiant stars. At the core of this cosmic whirlwind lies 30 Doradus B, its vivid colors and energetic shocks depicting the sheer power of supernovae.
