Neutron Star: A Dense Celestial Body After Supernova Explosion A neutron star is a rapidly rotating celestial body that forms after a supernova explosion. Despite its small size, only 20 km in diameter, a neutron star can have a mass comparable to that of the Sun. To illustrate the extreme density, a teaspoon of neutron star material on Earth would weigh over 500 million tons. This incredible mass is a result of electrons being forced into nuclei, causing them to merge with protons and form neutrons.

A rare phenomenon of a blue sunset was observed on the Red Planet. This unique event occurred due to the scattering of light in the thin Martian atmosphere, causing the sunlight to appear blue during sunset. Unlike Earth's sunsets, where the sky turns shades of red, orange, and pink due to the scattering of shorter-wavelength light, Mars' sunsets showcase a distinct blue hue. Scientists and space enthusiasts alike were captivated by this stunning spectacle, offering a glimpse into the mesmerizing and alien beauty of our neighboring planet.
