Near Earth Objects Danger and Studies

Near-Earth Objects or NEOs are those asteroids that have escaped the confines of the main belt.They roam freely among the planets of the inner Solar System in which Earth is the largest target.Asteroid 433 Eros was the first discovered to have left the main belt and crossed the orbit of Mars.Eros comes within 13 million miles of Earth's orbit. In March 1932, another Mars-crossing asteroid was discovered with a perihelion of 1.08 AU. It was given the name 1221 Amor. It became the prototype Mars-crosser with a perihelion between 1.0 AU and 1.3 AU.

Book of the Dead Mystery and Secrets

The "Book of the Dead" is an illustrated papyrus scroll placed in the tomb as a guidebook for the deceased during his perilous journey through the "Nether World" in the after life. The Book of the Dead is a composite of ancient Egypt's oldest and most important religious texts and magical spells. Some of the writings come from Egypt's Pre-dynastic period, and were 4,000 years old during the time of Jesus. The Book of the Dead is not a book as we know it, but rolls of papyrus that contain a collection of spells, incantations, prayers, hymns, and rituals that were written by the priests over Egypt's long history.

The Book of Gates in the Egyptian Mythology

One of three major myths about the sun god compiled in the New Kingdom(1550–1069 B.C.), the Book of Gates refers to the 12 gates separating the hours of the night.

It is a vast body of writings, spells, and incantations collected from the religious literature stored in temple libraries. The Gates divide the 12 hours of the night and separate the enemies that the sun god will encounter.

Similar myths tell a slightly different story of RE's perilous journey through the 12 hours of the night, and of his joyous rebirth in the eastern sky each morning.

Epsilon Aurigae Solved at Last?

A strange mystery puzzled scientists for years, now it might be solved with the help of newer technologies. A group of astronomers claims a breakthrough in the long-standing mystery of Epsilon Aurigae. This 3rd-magnitude star, a type-F super giant 130,000 times brighter than the Sun, loses half its light for almost two years every 27.1 years when a nearly opaque dust disk, seen edge-on, slides across its face.

Barlow Lenses and Focal Reducers

Simply, it's a concave (negative) lens placed between a telescope objective and eyepiece to increase the magnification, usually by two or three times. The negative lens reduces the angle of convergence of the light cone, effectively making it appear to the eyepiece that the primary has a longer focal length. It was invented in the early1800s by English physicist Peter Barlow (1776–1872)

Crop Circles, History and Theories

Strange circles or unusual geometric designs have been discovered in cereal crops around the world, even in the rice paddies of Japan. The designs are often hundreds of feet in diameter and length and may cover many acres. While many people believe that crop circles are a comparatively recent UFO-related phenomenon that began in the late 1970s or early 1980s, the mystery of the crop circle is hardly new. Unexplained geometric designs occurred in the fields of wheat and corn in Scotland in 1678, and rural residents of England speak of the "corn fairies" that made similar designs in the fields in the late 1800s.

Eyepieces for Telescope

What is the Eyepiece

The eyepiece is the lens assembly at the focal point of the telescope that forms and magnifies the image. Most telescopes, even department store types, come with at least one for initial use. Sadly today many of the major manufacturers deliver their telescopes with just that one eyepiece. Today’s Celestar 8 and Nexstar 8 telescopes,the current editions of the legendary Celestron C8, come with only a single 25-mm Plossl eyepiece (though Celestron does offer a nice observing kit that adds five more eyepieces and a filter set for under $100).

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.
