Glimpses, yes! Some shiny dots visible as afterglow from a kilonova. Don’t worry, I’ll explain.
First of all, a neutron star is the corpse of a collapsed star that was initially of 10 to 29 solar masses. Neutron stars are extremely dense, a compressed white dwarf to a density of atomic nuclei and a mass of at least 3 solar masses. The size? 10km radius. In other words, a neutron star is smaller than the city of Paris. You can imagine how difficult it is to observe and photograph such an object. There is however a feature that makes it possible to detect neutron stars. Radiation! And neutron stars, mostly young ones have that in abundance. One of the first actual images of a neutron star resulted from combining data from the Chandra X-ray Telescope with data from the Hubble Space Telescope and belongs to RX J1856.5-3754, a neutron star 652 to 1500 light years away, with a surface temperature of 700.000 degrees Celsius and a diameter of around 14km.


We have another – somewhat more evocative image – this time from two different binary neutron stars colliding into a kilonova. Like supernovae, kilonovae are violent cosmic events that occur when two neutron stars collide or when a neutron star collides with a black hole, resulting into gamma-ray bursts during the merging process. There are only a few documented and observed kilonovae, but the first one to have actually been recorded, occurred near the NGC 4996 galaxy, 130 million light years away, and detected by the LIGO facilities in Washington and Louisiana. The kilonova explosion between the two neutron stars was so powerful that it managed to outshine an entire galaxy, warping spacetime and sending waves throughout the entire universe. – Roman Alexander
