A Tale of Three Stellar Cities
Surprise: astronomers have found what look like three different generations of baby stars​ within the Orion Nebula Cluster.
The Orion Nebula is a large cloud of dust and gas​ where stars form.
Until now​, we thought all stars form at the same time in such a nebula
Using the OmegaCAM​ on ESO’s VLT Survey Telescope astronomers found something different...
...it seems that three generations of young stars​ formed in bursts in the Orion Nebula Cluster during the last 3 million years and will continue to grow older together.
