Astronomers have made an exciting discovery of an incredibly rare type of neutron star known as an X-ray transient. This type of star, called XTE J1906+090, has been found to be unusually persistent in its low luminosity X-ray state, which has been observed for the last 14 years. This is the longest period of low X-ray luminosity ever recorded by an X-ray transient, and it could provide insights into the physics of neutron stars. The findings were published in the journal Nature Astronomy.
