Short description: Luminous H II region
Sagittarius B1 also known as Sgr B1 is a luminous H II region in the galactic center.[1] The region is home to a lot of star formation making up 10% of the milky ways star formation in the last 100 million years even when it makes up 1% of the volume of the milky way galaxy.[2] Around six massive stars are located in Sagittarius B1 and evidence that tens of thousands of massive stars formed in SgrB1 within ~10 million years.[3] Stars around ~2 to 7 billion years old seem to be rare inside the inner regions of the nuclear stellar disk and might indicate inside out formation.[4]
