Scientists have identified a whole new type of “cosmic zombie” after analyzing an X-ray signal transmitted to the Swift Burst Warning Telescope (BAT) on June 3.

According to a report recently posted online on Astronomers Telegram, led by NASA, the signal source Swift J1555.2-5402 has been re-identified using the Neutron Star Inner Composition Discovery Telescope and the Ray Telescope.

Despite being so small, it weighs… twice as much as our Sun and carries 4 million times the energy of Earth. Compared to normal neutron stars, this new neutron star is up to 1,000 times more powerful.

A neutron star is a “cosmic zombie”, an energetic corpse after a massive star runs out of energy and explodes. This new type of neutron star is thought to have formed from a star 8-30 times larger than the Sun.

According to Science Alert, only 24 neutron stars have ever been identified, and six other “candidates” are in the process of being studied. We know they are formed by a massive star that dies, but we cannot yet explain how that death creates such a super-energy.
