The habitability of neutron star systems is the potential of planets and moons orbiting a neutron star to provide suitable habitats for life. [1] Of the roughly 3000 neutron stars known, only a handful have sub-stellar companions. The most famous of these are the low-mass planets around the millisecond pulsar PSR B1257+12.
The concept of life forms living on the surface of neutron stars was proposed by radio astronomer Frank Drake in 1973. Drake said that the atomic nuclei in neutron stars have large variety which might combine in supernuclei, analogous to the molecules that serve the base of life on Earth.
While Earth is the only place in the Universe known to harbor life, [10] [11] estimates of habitable zones around other stars, [12] [13] along with the discovery of thousands of exoplanets and new insights into the extreme habitats on Earth where organisms known as extremophiles live, suggest that there may be many more habitable places in the ...
A neutron star is so dense that one teaspoon (5 milliliters) of its material would have a mass over 5.5 × 10 12 kg, about 900 times the mass of the Great Pyramid of Giza. [b] The entire mass of the Earth at neutron star density would fit into a sphere 305 m in diameter, about the size of the Arecibo Telescope.
Dust comprising more than 200,000 times Earth's mass formed as debris after the explosion, making the area around the resulting neutron star too opaque to be studied using telescopes focused on ...
Evacuate Earth is a National Geographic Channel documentary that portrays the hypothetical scenario of humans evacuating the planet Earth before it is destroyed by a rogue neutron star. The documentary details the technical and social complications of building a generation ship to save humanity and other Earth organisms by relocating to a ...
If the moon's mass is not too low compared to the planet, it may in turn stabilize the planet's axial tilt, i.e. its obliquity against the orbit around the star. On Earth, the Moon has played an important role in stabilizing the axial tilt of the Earth, thereby reducing the impact of gravitational perturbations from the other planets and ...
A mysterious radio blast from space detected in 2022 originated in the magnetic field of an ultra-dense neutron star 200 million light years away.. Known as fast radio bursts, or FRB, such brief ...
