NASA’s Chandra X-ray Observatory captured a stunning image of the supernova remnant 30 Doradus B (30 Dor B). The image shows a region in the Large Magellanic Cloud, a small satellite galaxy, that is 160,000 light-years away

The image shows different types of light containing the remains of at least two exploded stars. Astronomers believe that the remnant could not have been formed by a single supernova, but instead by at least two. 

The image is a view of glowing hazes concentrated in the center, with purple, blue, and white colors

The image you are describing is a picture of supernova remnant 30 Doradus B, or 30 Dor B. It is a double supernova remnant, which means it was created by at least two supernovae. The remnant is located in the Tarantula Nebula, which is about 170,000 light-years from Earth. 

The remnant is about 50 light-years across and is made up of hot gas and dust. The purple, blue, and white colors in the image are caused by the different elements that are present in the remnant. The purple color is caused by sulfur, the blue color is caused by oxygen, and the white color is caused by nitrogen. 

The remnant is a popular target for astronomers because it is a relatively young remnant and is still evolving. Astronomers are studying the remnant to learn more about the processes that occur in supernovae and how they affect the surrounding interstellar medium.

NASA’s Chandra X-ray Observatory captured an image of 30 Doradus B, or 30 Dor B, a supernova remnant located in the Large Magellanic Cloud about 160,000 light-years from Earth. 30 Dor B is part of a region of space where stars have been forming for millions of years. 

The image was created by combining X-ray data from NASA’s Chandra X-ray Observatory (purple), optical data from the Blanco 4-meter telescope (orange), and infrared data from NASA’s Spitzer Space Telescope (blue). The different colors highlight different properties of the astronomical object being studied. 

The image shows that there has been evidence for at least two explosions tied to the supernova remnant 30 Doradus B.

The Chandra X-ray Observatory has made many discoveries, including: 

• Black holes The Chandra X-ray Observatory has discovered many black holes, including the smallest supermassive black hole and one of the most powerful black holes known. It also discovered a new type of black hole in galaxy M82, and evidence of a Type 2 quasar black hole. 
• Galaxies The Chandra X-ray Observatory has discovered two pairs of merging “dwarf” galaxies, and the shadow of a small galaxy being cannibalized by a larger one. 
• Stars The Chandra X-ray Observatory has detected more than 150 ordinary stars by the X-radiation from their coronas. 
• Star-planet interactions The Chandra X-ray Observatory has provided direct evidence of star-planet interactions, such as when XMM-Newton caught flares from the HD 17156 system. 

The Chandra X-ray Observatory is the most powerful X-ray telescope ever built. It can detect X-rays from matter at extremely high temperatures, such as supernova remnants, black holes, and galaxy clusters

The Chandra X-ray Observatory is designed to observe X-rays from high-energy regions of the universe. These regions include: 

• Exploded stars 
• Clusters of galaxies 
• Matter around black holes 

The Chandra X-ray Observatory also observes other sources of high energy, such as: Quasars, Supernovas. 

The Chandra X-ray Observatory has provided valuable insights into the cosmos, including: 

• Two intergalactic clouds of diffuse hot gas 
• The Vela Pulsar, which provided the first direct evidence that neutron stars were formed during supernova explosions 
• The Crab Nebula, which is the result of a supernova that astronomers observed in 1054

The Chandra X-ray Observatory has several instruments, including: 

• High Energy Transmission Grating Spectrometer (HETGS): A spectrometer that focuses on high resolution spectroscopy 
• Low Energy Transmission Grating Spectrometer (LETGS): A spectrometer that focuses on high resolution spectroscopy 
• High Resolution Camera (HRC): One of two instruments that the High Resolution Mirror Assembly (HRMA) focuses X-rays onto 
• Advanced CCD Imaging Spectrometer (ACIS): The primary scientific instrument on the Chandra X-ray Observatory. It uses a charge-coupled device detector to record the position and energy level of each X-ray that hits it 
• Aspect Camera: Includes a visible-light telescope and CCD camera attached to the X-ray telescope 

The Chandra X-ray Observatory also has two X-ray transmission gratings that can be inserted into the X-ray path. These gratings are grating arrays that can be flipped into the path of the X-rays to redirect them based on their energy. 

The Chandra X-ray Observatory has two detectors: the Advanced CCD Imaging Spectrometer (ACIS) and the High Resolution Camera (HRC). The ACIS is the primary imaging detector, and the HRC is made up of two microchannel plate (MCP) imaging detectors: 

• HRC-I: Designed for wide-field imaging 
• HRC-S: Designed to serve as a readout for the LETG 

The ACIS is an array of CCDs that are sensitive to X-ray light. X-ray photons scattered into the focal plane from the mirrors hit a pixel in the detector and light it up. 

The HRC detects X-rays reflected from an assembly of eight mirrors. The HRC-I is a 90mm square detector optimized for imaging. The HRC-S is a 20 X 300 mm rectangular detector optimized for use with the LETG transmission gratings experiment.

The Chandra X-ray Observatory detects black holes by identifying their intense gravitational pull and capturing the X-rays emitted by the heated matter around them. 

Black holes are detected as surrounding material is funneled by the force of gravity into a disk around the black hole. The gas molecules in the disk swirl around the black hole so fast that they heat up and emit X-rays. These X-rays can be detected from Earth. 

The Chandra X-ray Observatory also measures the energy output and flaring from Sagittarius A*. The rapidity of the variations in the X-ray emission indicates that they are occurring near the event horizon, or point of no return, around the black hole

The Chandra X-ray Observatory is an Earth satellite that orbits 139,000 kilometers (86,500 miles) above the Earth’s atmosphere. This is because the Earth’s atmosphere absorbs X-rays, making them undetectable from Earth-based telescopes

Chandra has an elliptical orbit that takes it more than 138,000 kilometers from Earth and then back to within 9600 kilometers of Earth. Chandra cannot take science observations while it travels through Earth’s radiation belts, as the radiation can disturb its sensitive instruments
