WHY PLUTO IS NOT CONSIDERED A PLANET ANYMORE?

PLUTÓN fue descubierto el 18 de febrero de 1930 por el astrónomo estadounidense Clyde William Tombaugh (1906-1997) desde el Observatorio Lowell en Flagstaff, Arizona, y considerado el noveno y más pequeño planeta del Sistema Solar por la Unión Astronómica Internacional y por la opinión pública desde entonces hasta 2006, aunque su pertenencia al grupo de planetas del Sistema Solar fue siempre objeto de controversia entre los astrónomos. Tras un intenso debate, la UAI decidió el 24 de agosto de 2006, por unanimidad, reclasificar Plutón como planeta enano,... pincha aquí para seguir leyendo.

“Why do dark colours absorb heat?”

Have you ever been told that wearing light colours on a hot day will keep you cooler? Dark colours get hotter than light colours for one big reason: Dark colours absorb more light!

In fact, without light there wouldn’t be any colour at all! When we see colour, it’s because we see light that gets reflected off of something.

Do you have a blue shirt? The reason it looks blue is because when sunshine (or another type of light) hits the shirt, most of the light’s energy is absorbed by the shirt, but the blue energy of light bounces off the shirt. Our eyes can see the energy that bounces off, and to us, the shirt looks blue.

Lighter colours reflect the most light. Darker colours absorb more, but all of that absorbed energy doesn’t just disappear! Energy never just disappears, but it can change. Light that gets absorbed by clothing becomes heat!

Light energy is what makes your warmer, so if you want to cool down, wearing a colour that reflects a lot of light energy is a good choice. 

                         

LIGHT FACTS

Brighten your science knowledge with these fun light facts for kids:

• In physics, light refers to electromagnetic radiation. The light we normally talk about in everyday life refers to the visible spectrum (the part of the electromagnetic spectrum that the human eye can see).

• Other animals can see parts of the spectrum that humans can’t. For example, a large number of insects can see ultraviolet (UV) light.

• UV light can be used to show things the human eye can’t see, coming in handy for forensic scientists.

• The wavelength of infrared light is too long to be visible to the human eye.

• Scientists study the properties and behaviors of light in a branch of physics known as optics.

• Isaac Newton observed that a thin beam of sunlight hitting a glass prism on an angle creates a band of visible colors that includes red, orange, yellow, green, blue, indigo and violet (ROYGBIV). This occurred because different colors travel through glass (and other mediums) at different speeds, causing them to refract at different angles and separate from each other.

• Light travels very, very fast. The speed of light in a vacuum (an area empty of matter) is around 186,000 miles per second (300,000 kilometres per second).

• Light travels slower through different mediums such as glass, water and air. These mediums are given a refractive index to describe by how much they slow the movement of light. Glass has a refractive index of 1.5, meaning that lights travels through it at around 124,000 miles per second (200,000 kilometres per second). The refractive index of water is 1.3 while the refractive index of air is 1.0003, meaning that air only slightly slows down light.

• Light takes 1.255 seconds to get from the Earth to the Moon.

• Sunlight can reach a depth of around 80 metres (262 feet) in the ocean.

• One of the many things Italian scientist Galileo Galilei worked on was telescopes, producing telescopes with around 30x magnification in some of his later work. These telescopes helped him discover the four largest moons orbiting Jupiter (later named the Galilean satellites).

• Photosynthesis is a process that involves plants using energy from sunlight to convert carbon dioxide into food.
