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.

Panasonic unveils first handheld 3D camcorders

The camcorders look like regular handy-size video cameras and can capture conventional 2D video and images, but by adding a conversion lens adapter, they can capture in 3D. The adapter has two small lenses that each capture a slightly different image of the scene being shot. The right-eye and left-eye images are recorded side-by-side and are what's needed to create a video image with the illusion of depth.

What is the God Particle ?

The most asked, most controversial question in physics today is what determines mass in an object. It is mentioned on the movie "Angels and Demons", the "God Particle" is the nickname of a subatomic particle called the Higgs boson. In layman’s terms, different subatomic particles are responsible for giving matter different properties. One of the most mysterious and important properties is mass. Some particles, like protons and neutrons, have mass.

News: Europa Has Enough Oxygen For Life

A hope seems to appear, as new research suggests that there is plenty of oxygen available in the subsurface ocean of Europa to support oxygen-based metabolic processes for life similar to that on Earth. In fact, there may be enough oxygen to support complex, animal-like organisms with greater oxygen demands than microorganisms.

Information obtained through the GPS function, iStellar will chart the location of stars and will rotate according to the position detected by the position sensor. It is optimized for Multi-Touch control, allowing you to operate intuitively; drag to move the star chart, pinch to zoom in and out, and so on.

Low budget Astrophotography

Astrophotography may sound to be a huge step for beginners and is only reserved to professionals who spend years and years in this hobby and with quite expensive gadgets. As a matter of fact it needs good experience, but you will educate yourself with trial and error time after time, but to be honest, it's very tricky and maybe impossible to have results like the powerful high-end imaging devices, especially when imaging deep sky objects, but with cheaper equipment you can create decent images if you know how to tweak'em to the limits, now we will see how it's done.

The Newtonian Reflector Telescope

This Uniquely-look telescope first developed by another pioneer in science, Sir Isaac Newton. The design of this telescope is fairly simple. Other than the lenses in the eyepiece, there is only one surface that has a curve in it (the primary mirror).

Light Pollution

We begin with the greatest impediment of all to observing the heavens in today’s world. Light pollution is excessive or misdirected artificial outdoor lighting. It does no one any good, and almost everyone considerable harm.

Sky Navigation: Altitude and Azimuth

Whatever the celestial object you desire to observe, you first need to find it(obviously), when we talk about stars (or any other celestial objects) we need to have a system for identifying where they are in the sky.

Refracting Telescopes

When a "Telescope" term come in mind, we always think of that tube with the big lens and the small one we look in. Though its inventor may be lost in history, this early kind of telescope is called a "Galilean" or simple refractor. The Galilean refractor consists of two lenses: a convex (curved outward) lens held in front of a concave (curved inward) lens a certain distance away. As you know, the telescope’s front lens is called the objective, while the other is referred to as the eyepiece, or ocular.

Starter Telescope Models for Beginners

What to consider ?

There are a wide rang out there you can pick from. And I will try here to review and show you some of these models which are recommend for a beginner, compared to the cost.

Buying a Telescope for Beginners

So, you intend to buy a telescope, my belief that there are three primary concerns a beginner should have when buying a first scope: cost, size (& type), and reliability. Those three aspects are very common when you decide to buy whatever you put in mind, so we will try to follow them from a amateur point of view or just a father who want to get his son the scope he always dreamed of.
