What are some interesting lightning facts?

Lightning can heat the air it passes through to temperatures of about 30,000 °C (54,000 °F). That is regarded as 5 times hotter than the surface of the sun. The discharge process, or return stroke, of the lightning is the most luminous part where the electric current moves through the channel. One observation found that the rate at which the return stroke current traveled was around 100,000 km/s (or one-third the speed of light). Global monitoring indicates that lightning on Earth occurs at an average frequency of approximately 44 (± 5) times per second.

What is the density of a neutron star?

A neutron star is so dense that one teaspoon of its material would have a mass over 5,500,000,000 tonnes (5.5 billion), about 900 times the mass of the Great Pyramid of Giza (often cited as 5.9 million tons / 5.3 million tonnes). At the extraordinarily

Are sharks older than trees?

400 million years ago, in the Devonian period, cartilaginous fishes such as primitive sharks became more numerous. The first tree dates to about 385 million years ago, and the Dinosaur Age started 252 million years ago, making sharks older than trees and dinosaurs. One galactic year (the duration of time

Do sea turtles sense Earth’s magnetic fields to navigate?

Evidence is mounting that loggerhead turtles use a form of navigation termed Magnetoreception. This allows them to sense the Earth’s magnetic field. It has been observed that young loggerhead turtles inherit a magnetic map and magnetic compass sense that guides their first transoceanic migration. The turtles change their migration

Can an electric eel stun a horse?

The electric eel can stun their prey by delivering a shock of up to 860 volts. According to one study, the shocks from leaping electric eels are powerful enough to drive away animals as large as horses by activating the nociceptor sensory neurons in the horse. The electric eel stacks
