Radio Astronomers Take Close Look at Flame Nebula

The Flame Nebula is the large feature on the left half of the central, yellow rectangle. The smaller feature on the right is the reflection nebula NGC 2023. To the top right of NGC 2023, the iconic Horsehead Nebula seems to emerge heroically from the ‘flames.’ The three objects are part of the Orion cloud, a giant gas structure located between 1,300 and 1,600 light-years away. The different colors indicate the velocity of the gas. The Flame Nebula and its surroundings are moving away from us, with the red clouds in the background receding faster than the yellow ones in the foreground. Image credit: ESO / Thomas Stanke / J.

Using the recently-installed SuperCam instrument on ESO’s Atacama Pathfinder Experiment (APEX) in the Atacama Desert, Chile, astronomers have produced a new radio image of the Flame Nebula. The Flame Nebula is the large feature on the left half of the central, yellow rectangle. The smaller feature on the right is the reflection nebula NGC 2023. To the top right of NGC 2023, the iconic Horsehead Nebula seems to emerge heroically from the ‘flames.’...
