This open star cluster within the Eagle Nebula is home to stellar "toddlers" that formed recently. They emit ultraviolet radiation that causes the surrounding nebula of cosmic material to glow.

Impressive statistics! Thanks for the amazing catalogue that helps producing so many new results just from the existing observations in the archive. 8)

The Gaia NS1 binary system has a 731 day orbital period, with an almost circular orbit. The dark companion most likely formed with little mass loss & only a weak natal kick (a kick given at the neutron star's birth, usually increasing its velocity).
Gaia NS1 has a mass of 1.9 solar masses, its full mass contained in a sphere of about 10km radius. Its companion star is metal-poor and belongs to the halo. Couldn't it be a very small black hole? Probably not, so far there is no evidence of such small black holes existing.
Most neutron stars are detected as radio pulsars. Now, Gaia allows to find neutron stars part of binary systems. While the dark neutron star orbits its luminous companion, the position of the luminous companion experiences a slight wobble 👉🏿
The non-single star catalogue of
#GaiaDR3
brought many a treasure! Now, Gaia could have discovered its first neutron star! Gaia finds these in the Milky Way but similar-mass objects were found in distant galaxies through gravitational-wave observatories.
