We may finally know how impossible stars at our galaxy's centre formed

The centre of the Milky Way is home to more than 100 young stars that shouldn’t exist. Researchers may have now finally figured out how they formed

Illustration of the Milky Way galaxy as it might appear edge on. The Milky Way is a barred spiral galaxy roughly 100000 light-years in diameter. It is flat, shaped like two fried eggs back-to-back. At the centre is the nucleus, a vast flattened ball of old, red stars orbiting a supermassive black hole. This view imagines our galaxy seen from far from its nucleus, within the galactic plane. A lane of dust bisects the galaxy. Globular clusters (spherical clusters of stars) orbit here. One is seen in close up on the lower right.

Illustration of our galaxy, the Milky Way seen obliquely, with the arms and the central bar in their approximate known locations. There are four major arms and one arm fragment (Orion-Cygnus or Local) where the Sun is found. In the annotated version of this image, the yellow dot indicates the position of the Solar System about 25000 ly from the galactic core. The Norma and Outer arms are in fact the same, but the two names refer to different parts of it. The same is true of the so-called 3kpc (3 kilo-parsec) arm, which further out becomes the Perseus arm.
