Neutron stars are the collapsed cores of massive stars that have undergone a supernova explosion. Despite being only about 10–15 kilometers (6–9 miles) in diameter, they can contain more mass than the Sun. This makes them the densest objects in the universe, where a single teaspoon of neutron star material would weigh billions of tons on Earth.
Venus has one of the strangest rotations in the solar system one day on Venus (one full rotation on its axis) takes 243 Earth days, while it orbits the Sun in just 225 Earth days. This means a year on Venus is shorter than a single day. Additionally, Venus rotates in the opposite direction compared to most planets, including Earth. This unusual rot
The Eiffel Tower, one of the most iconic landmarks in the world, expands during summer due to heat. Made primarily of iron, the structure absorbs heat from the sun, causing it to expand by up to 15 centimeters (6 inches) in height. This phenomenon occurs because of thermal expansion, where metals increase in size when heated and contract when coole
Octopuses are fascinating marine creatures with a unique circulatory system they have three hearts instead of one. Two of these hearts, called branchial hearts, pump blood to the gills for oxygenation, while the systemic heart circulates oxygen-rich blood throughout the body. What’s even more interesting is that when an octopus swims, its systemi
