Science for Kids: Things you didn't know about Light

What is "Light"

Light is a type of energy. It is a form of electromagnetic radiation of a wavelength which can

be detected by the human eye. In physics, the term light sometimes refers to electromagnetic

radiation of any wavelength, whether visible or not. Light exists in tiny packets called photons.

It shows properties of both waves and particles. The study of light, known as optics, is an important

research area in modern physics.

What are the types of galaxies

Galaxies are certainly among the most popular telescope targets for amateur astronomers. They show an incredibly wide range of size, shape, and internal structure has undoubtedly lead to their fascination among both amateurs and professional astronomers alike. they are vast groups of stars, dust, and gas ranging from a few thousand to nearly a million light-years in diameter. 

Their respective masses show a similarly broad range from less than a million to well over trillion solar masses. This variety of shape and form is far greater than in any other class of deep sky objects.

Inception Lucid Dreaming, The Easy Way

Inception was a major blockbuster movie introduced in summer 2010, indeed was a stunning movie yet mind blowing one, written and directed by Christopher Nolan (The Dark Knight, Memento) and starring an international cast (Leonardo DiCaprio, Ellen Page, Cillian Murphy, Joseph Gordon-Levvit and Michael Cain). It was held in the near future and it's main idea was about controlling and sharing dreams by a matrix-like system, also talks about sub-dreams or dreams within dreams, and inserting ideas to the subconscious using "dreams", So it's all about dreaming, although sub-dreams and dreams sharing are pure science fiction(so far), there is a method you can do to control your own dreams and make it vivid as possible using the massive engine in your head called the "subconscious", this method is known as "Lucid Dreaming", it is not easy to achieve and need a lot of training, but here i'm going to tell you how it's done easily with minimum practice.

Gamma Ray Burst Danger and Studies

For 25 years, cosmic gamma ray bursts (GRBs) have been one of the great mysteries of modern astronomy. GRBs have given us several clues as to what they might be. GRBs were seen to occur frequently and appeared to be spread evenly over the sky. Their distribution on the sky indicated that they were the result of events happening either very close or very far (in other galaxies). The events were not, for example, seen to be concentrated in the plane of our Galaxy.

What are Nazca Lines

The Nazca Lines, also known as Nazca figures, Nazca Pictures and Nazca Images, are an engima. No one know who had built them or indeed why. Since their discovery, the Nazca Lines have inspired fantastic explanations from ancient gods, a landing strip for returning aliens, a celestial calendar, used for rituals probably related to astronomy, to confirm the ayllus or clans who made up the population and to determine through ritual their economic functions held up by reciprocity and redistribution or, a map of underground water supplies.

When Giant Black Holes Collide

,,When giant black holes collide, the surrounding space-time trembles,,

The collision of two supermassive black holes in the aftermath of a galaxy merger is the ultimate cosmic cataclysm, throwing out more energy for about an hour than all the visible stars in the entire universe combined. Moreover, in order to form the billions of majestic galaxies scattered across the sky, astronomers think that such events must have happened frequently as the first galaxies consolidated and grew.

What happens when galaxies collide?

When two nearby galaxies attracted to each other by their gravitational force (a relatively common event in galaxy evolution), their gases collide violently. As gas and dust smash together at speeds of millions of miles an hour, they combine the raw materials for new born stars in an amazing hot and bright display, and eventually -in some cases- causes a super massive black hole from this collision.

Sunspot: Sharpest View Yet in Visible Light

This crisp view of a sunspot, captured by New Jersey Institute of Technology's New Solar Telescope and released last week, may be the most detailed picture of its kind yet shot in visible light, astronomers say.

Sun storm to hit earth with 'force of 100m bombs' in few years

After about ten years of sleeping, the giant is waking up - and it's got astronomers on full alert.

This week several US media outlets reported that NASA was warning the massive flare that caused spectacular light shows on Earth earlier this month was just a precursor to a massive solar storm building that had the power and potential to wipe out the entire planet's power grid.

Sea of the Devil: Dragon Triangle

The Bermuda triangle's infamous association with disappearing boats and aircraft is known across the globe. Less well known is an area off the west coast of Japan which has an equally deadly history. It is an area where Japanese sailors fear to voyage; they call it 'Ma-no Uni' – the "Sea of the Devil".
