Astronomers Spot Hundreds of Massive Gas Clouds Escaping Milky Way’s Center

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.

This ALMA image shows the outcome of a stellar fight: a complex and stunning gas environment surrounding the binary system HD 101584. The colors represent speed, going from blue (gas moving the fastest towards us) to red (gas moving the fastest away from us). Jets, almost along the line of sight, propel the material in blue and red. The stars in the binary are located at the single bright dot at the center of the ring-like structure shown in green, which is moving with the same velocity as the system as a whole along the line of sight. Astronomers believe this ring has its origin in the material ejected as the lower mass star in the binary spiraled towards its red-giant partner.
