Neutron stars are incredibly dense remnants of massive stars that have collapsed under their gravity after exhausting their nuclear fuel.<\/p>\n<p>2. They are the densest stellar objects known, containing about 1.4 times the mass of the sun compressed into a sphere roughly 10 to 20 kilometers in diameter.<\/p>\n<p>3. Neutron stars possess extreme magnetic fields, intense gravity, and can spin rapidly, emitting beams of radiation detectable as pulsars.<\/p>\n<h2>About Pulsars<\/h2>\n<p>1. Pulsars are a type of neutron star that emits beams of electromagnetic radiation from its poles. As the star rotates, these beams sweep across space creating a pulsing effect when observed from Earth.<\/p>\n<p>2. Pulsars are known for their precise and regular pulsing, making them cosmic timekeepers.<\/p>\n<p>3. All pulsars are neutron stars, but not all neutron stars are pulsars.<\/p>\n<h2>About Cepheids<\/h2>\n<p>1. Cepheids are a type of variable star that pulsates in brightness due to the expansion and contraction of their outer layers. These stars shine with a luminosity 500 to 30,000 times greater than that of the Sun.<\/p>\n<p>2. These stars, which are hot and massive ranging from five to twenty times the mass of our Sun exhibit radial pulsations that cause variations in both their diameter and temperature.<\/p>\n<h2>About Nebulae<\/h2>\n<p>A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova.<\/p>\n<p><strong>UPSC Syllabus: Science and technology<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Source- This post on Objects in space\u00a0has been created based on the article \u201cWhat are neutron stars?\u201d published in \u201cSpace.com\u201d\u00a0on 8 August 2024.
