Astronomers have discovered black widows and redbacks in space. Although these cosmic objects do not kill and eat their companions, the stars share the violent behavior of their eight-legged companions.
In addition to the run-of-the-mill spider stars, researchers also detected a bizarre black widow-redback crossdress. Scientists used the now-destroyed Arecibo telescope in Puerto Rico to search for strange stars.
Spider stars are types of millisecond pulsars, or Neutron stars It acts like precise clocks in the sky, rotates at least once every 30 milliseconds and shines like a lighthouse on each turn. Neutron stars, smaller, narrower stars of older, exploded stars, often take rip-off material from other stars locked in binary orbits with them and use the push of that transgressive material to reach pulsar motion. Spider stars are rare and special versions of these stars, however: they get so close to their binary companions that they explode their surfaces, emitting large amounts of material like a spider, like its companion organ. Cut from the limb.
In a new paper, researchers identified three new black widows and a redback in the Milky Way. He also found a spider star that defines taxonomy, almost like a crossbridge of two species.

When a spider star has reduced its companion by less than one-tenth the mass of the sun (usually 0.03 to 0.03 times the mass of the sun), that star is called a black widow. Redbacks have haftier companions that boast more than a tenth of the sun’s mass. These binary companions of the redback periodically pass between the spider’s star and the Earth, causing temporary eclipses. The shrunken companions of black widows usually do not pull that trick.
It appears that the crossbird star is difficult to classify. For now, researchers have re-labeled it because its partner sometimes eclipses its tick light. And the mass of that companion is at least 0.055 times (possibly larger) the mass of the sun, which would be quite heavy for a black widow, although much lighter for a comeback. For now, the exact mechanisms of that system are still a mystery.
