A container garden is a type of garden that is grown in containers such as pots, baskets, or boxes instead of directly in the ground. Container gardens can be created in any outdoor or indoor space with access to sunlight, and are often used in small urban areas where traditional gardening space is limited.Read More
Universal Design: The Case for Accessibility for the Physically-Challenged
When it comes to public buildings, architects and designers have the responsibility of creating structures and facilities that can be used by as many people as can be.Read More
Build Loyalty in Your Company
Good employees are the backbone of every company. However, changing times and a stricter economy has made retaining them a tall order. Companies are waging salary wars, and head-hunting is an accepted norm. The companies with higher offers often get their men, but it’s not always the case. Cultivate loyalty in your employees, and you’ll find out that it’s not always about the money.Read More
What is the Sun?
The Sun is a star in our Milky Way
The Sun gives off energy as electromagnetic radiation. That includes light, infra-red energy (heat), ultraviolet light and radio waves. It also gives off a stream of particles, which reaches Earth as solar wind. The source of all this energy is the reaction in the star which turns hydrogen into helium and makes huge amounts of energy.
The Sun gives off energy as electromagnetic radiation. That includes light, infra-red energy (heat), ultraviolet light and radio waves. It also gives off a stream of particles, which reaches Earth as “solar wind”. The source of all this energy is the reaction in the star which turns hydrogen into helium and makes huge amounts of energy.
The Sun is a star like many others in our Milky Way galaxy. It has existed for a little over 4.5 billion years, and is going to continue for at least as long. The Sun is about a hundred times as wide as the Earth. It has a mass of 1.9891×1030 kg, which is 333,000 times the mass of the Earth. The Earth can also fit inside the Sun 1.3 million times.
What is SpaceX?
SpaceX is an American aerospace manufacturer and space transport services company
Space Exploration Technologies Corporation, better known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California, United States. It was founded in 2002 by Tesla Motors CEO and former PayPal entrepreneur Elon Musk with the goal of creating the technologies to reduce space transportation costs and enable the colonization of Mars. It has developed the Falcon 1 and Falcon 9 launch vehicles, both designed to be reusable, and the Dragon spacecraft which is flown into orbit by the Falcon 9 launch vehicle to supply the International Space station (ISS) with cargo. A manned version of Dragon is in development.
SpaceXs achievements include the first privately funded, liquid-propellant rocket (Falcon 1) to reach orbit, in 2008; the first privately funded company to successfully launch, orbit and recover a spacecraft (Dragon), in 2010; and the first private company to send a spacecraft (Dragon) to the ISS, in 2012. The launch of SES-8, in 2013, was the first SpaceX delivery into geosynchronous orbit, while the launch of the Deep Space Climate Observatory (DSCOVR), in 2015, was the companys first delivery beyond Earth orbit.
SpaceX began a privately funded reusable launch system technology development program in 2011 and, in December 2015, successfully returned a first stage back to a landing pad near the launch site and accomplished a propulsive vertical landing. This was the first such accomplishment by a rocket on an orbital trajectory. On April 8, 2016, with the launch of CRS-8, SpaceX successfully vertically landed a first stage on an ocean drone-ship landing platform on a mission that also delivered a Dragon space capsule to Low Earth Orbit. On May 6, 2016, SpaceX again landed a first stage, but on a geostationary transfer orbit mission, another first.
What is the Moon?
The Moon (Latin: luna) is Earths satellite, and we can usually see it in the night sky
Our moon is about a quarter the size of the Earth. Because it is far away it looks small. The gravity on the moon is one-sixth of the Earth’s gravity. It means that something will be six times lighter on the Moon than on Earth. The Moon is a rocky and dusty place. The Moon drifts away from Earth at the rate of four centimeters each year.
The Moon is lit up by the sun as it goes around (or orbits) the Earth. This means sometimes people on Earth can see the whole Moon and other times only small parts of it. This is because the Moon does not send out its own light. People only see the parts that are being lit by sunlight. These different stages are called Phases of the Moon.
Humans finally landed on the Moon on 21 July, 1969. Astronauts Neil Armstrong and Buzz Aldrin, landed their lunar ship (the Eagle) on the surface of the moon. Then, as half the world watched him on television, Armstrong climbed down the ladder of the Eagle and was the first human to touch the Moon as he said, “That’s one small step for a man, one giant leap for mankind.”
What is Mars?
Mars is the fourth planet from the Sun in the Solar System and the second-smallest solid planet
Mars is the fourth planet from the Sun in the Solar System and the second-smallest solid planet. Mars is rocky and cold, with polar ice caps of frozen water and carbon dioxide. It has the largest volcano in the Solar System, and some very large impact craters. Mars is named after the mythological Roman god of war because it is a red planet, the colour of blood.
The planet Mars is made of rock. The ground there is red because of iron oxide (rust) in the rocks and dust. The planet’s atmosphere is very thin and contains a lot of carbon dioxide and a very tiny amount of oxygen. The temperatures on Mars are colder than on Earth, because it is farther away from the Sun and has less air to keep warmth in. There is water ice and frozen carbon dioxide at the north and south poles. Mars does not have any liquid water on the surface now, but signs of run-off on the surface were probably caused by water. Mars has two small moons, called Phobos and Deimos.
What does NASA mean?
NASA means National Aeronautics and Space Administration
NASA is an independent agency of the United States federal government responsible for the civilian space program as well as aeronautics and aerospace research.
President Dwight D. Eisenhower established NASA in 1958 encouraging peaceful applications in space science. Since that time, most US space exploration efforts have been led by NASA, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program (LSP) which provides oversight of launch operations and countdown management for unmanned NASA launches. NASA is also responsible for the training of astronauts.
What is Andromeda Galaxy?
The Andromeda Galaxy is the nearest spiral galaxy to the Milky Way, our galaxy
The Andromeda Galaxy is the nearest spiral galaxy to the Milky Way, our galaxy. Andromeda is sometimes called M31 or NGC 224 by astronomers. It is about 2.6 million light years away from us.
Andromeda is the largest galaxy of the Local Group, which consists of the Andromeda Galaxy, the Milky Way Galaxy, the Triangulum Galaxy, and about 30 other smaller galaxies.
At an apparent magnitude of 3.4, the Andromeda Galaxy is notable for being one of the brightest Messier objects, making it visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution. Although it appears more than six times as wide as the full Moon when photographed through a larger telescope, only the brighter central region is visible to the naked eye. Being both large and bright, it is one of the farthest objects that can be seen without a telescope or binoculars.
What is Ganymede?
Ganymede is the largest moon of Jupiter
Ganymede is the largest moon of Jupiter. It is also the largest moon in the Solar System. Ganymede is larger in diameter than Mercury, but has only about half its mass. Ganymede is much less dense. Ganymede is part of a group called the Galilean Satellites. These also include Io, Europa and Callisto.
Galileo Galilei discovered this moon in 1610. Simon Marius suggested the name Ganymede soon after. In Greek mythology, Ganymede was Zeus’ cup-bearer. Ganymede is the only Galilean moon of Jupiter named after a male figure.
