Satellites

An artificial satellite is an object that has been put into orbit in outer space by human effort. A remote sensing satellite contains within it sensors that enable it to collect information about an object without physical contact with the object. There are two types of sensors i.e. passive sensors and active sensors. Passive sensors […]

Lunar Surveyor Program

Introduction Unlike the previous exploration missions on the moon like the Ranger missions, Surveyor missions were planned in such a way that spacecraft would make soft lunar landings. The program was over-ambitious at first. The initial plan was that NASA would launch a Lander and an orbiter, and that it would perform several scientific experiments. […]

Life outside planet Earth

Introduction All living things have one thing in common. All living things are carbon-based and that they need water to survive. Water is therefore important to sustain life. There is no need to elaborate the reason why water is a crucial ingredient in a habitable planet. Water must be used as a primary requirement in […]

System Development

Overview NASA initiated a program in 1993 that was referred as Mars Surveyor program with an objective of conducting on-going missions to explore Mars. The Jet Propulsion Laboratory (JPL) was assigned the role for leading the program. The MCO was launched in 11, 1998. It was supposed to reach Mars in December 1999 as the […]

Nebular Model of the Solar system

Introduction Philosophers and scientists, particularly the astronomers, have been looking for information pertaining to how the universe was formed. Even though there is no single authoritative model that explains the manner in which the universe was formed, there is one model that satisfies the highest share of astronomers: the nebular hypothesis or model. The model […]

Life in This Universe

Researchers have speculated whether there is life elsewhere apart from Earth for many years. There are two different scientific thoughts that explain the existence of life in the Universe. The first school of thought is the Rare Earth Hypothesis. It suggests that the possibility of life existing in other parts of the Universe is very […]

History of the Telescope

Introduction Telescope is an instrument used to observe minute objects. It has the capability of collecting and analyzing radiations from objects that are at a distance. It has an electromagnetic spectrum that helps to magnify the size of an image when taking a photograph. Information is also collected/ gathered through image sensor. There are various […]

Planets around stars

There is an opinion that our universe is endless, however, we have too little knowledge about it. Scientists all over the world develop different theories and search for new planets. There are a lot of various theories about the creation and development of new planets. The problem of the endless of the universe is also […]

Planetary habitability

Over several decades, scientists have continuously searched the universe for planets with the potential of supporting life (Silverman 1). In the Solar System, however, the Earth is the single planet located in the habitable zone of the star and offers the ‘just right’ environment for life to originate and develop (Science News 1). Consequently, research […]

Misconception about the Sun

Introduction Misconception is considered as “any unfounded belief that does not embody the element of fear, good luck, faith, or supernatural interventions” (Hancock, 1940, p. 208). This can be also misunderstandings, misleading or misinterpretating ideas and facts (Barrass, 1984). This particular essay aims at explaining some of the misconceptions that kindergarten students have concerning the […]

Encounter with Mercury

Introduction The solar system is comprised of nine planets and each planet rotates on its own axis. Mercury is the innermost planet because of its close proximity to the sun. This planet can hardly support any life because the temperatures within its atmosphere are very high1, 2. However, it is difficult to observe Mercury because […]

Space Debris Problem

Abstract Apart from the looming climate change and global warming, the world is facing a disaster in her space infrastructure, if space debris continues to fill the orbit. Records from NASA shows that, over 19,000 of debris, which are more than 1 cm in size, have been tracked, but more is believed to exist that […]

The Lowell Observatory

Introduction The space contains various wonders objects with significant effects on the study of astronomy. A wide range of research is commonly conducted in space to establish and prove various theories that are aimed at explaining the origin and significance of these heavenly bodies. The space was largely unknown to many in the ancient times. […]

Pluto Exploration

Pluto has long been considered as the ninth planet from the sun. It is the sixth planet from the earth. It is so far away that for many centuries, astronomers and scientists were not able to study this planet as extensively as they would have wanted. But because of the rapid improvement in technology whether […]

The Nebula cloud theory

Scientists and astronomers the world over ascribe to the idea that the formation of the solar system is best described by the solar Nebula model. They also concur that the best theory behind the formation of the solar system and the nebula model is the Nebula hypothesis. The hypothesis builds on the idea that the […]

The Copernican Revolution

Introduction Modern science can be said to have its roots from the Copernican theory, though it was received with uncertainty by the Copernicans prior to the seventeenth century (Curd 3). Most of the scientists in the sixteenth century believe Ptolemy’s theory of Earth-centered astronomy, as well as Tycho Brahe’s theory of Geoheliocentric system. The reluctance […]

How can we detect life on extrasolar planets?

Abstract Extrasolar planets are planets that are found outside the solar system. Mathematical probability shows that some of these planets may contain life. However, this needs to be proven using credible scientific evidence. The current scientific methods to search for extrasolar life heavily depend on telescopes. The available telescopes however are not big enough to […]

Comets and asteroids

Introduction Bodies that orbit the sun face many threats posed by crashing asteroids and comets. Scientific investigations have revealed that comets and asteroids which orbit the sun sometimes alter their orbital trajectory, disintegrate into fragments, and pose the kind of threat that caused the extinction of dinosaurs millions of years ago when an asteroid crashed […]

History of Astronomy

Phases of Astronomy Until the present day, astronomy had its origin in antiquity, based on the study and observation of physical objects such as the moon and the sun. These were closely interlinked with mythology and religion. The Mesopotamian era catalogues stars, a time when a circle was first divided into 360 degree. This was […]

Large-scale universe to Milky Way

Modern cosmology Different communities hold different views about the initiation of the universe. The ancestors explained the universe using various unsubstantiated myths and misconceptions based on their everyday observations. Biblical view embrace nature while cosmologists put it that the universe begun by an explosion called Big Bang. Modern cosmology gained popularity around 1918 following the discoveries of Robert Einstein as it pertains […]

20/20 Hindsight

Introduction In the daily running in life, people engage in many premeditated and involuntary activities. Most of the impromptu ones that come up require rush and closest to accurate decision making. It is from these that individuals make most mistakes at the end of the day. It may be considered a better way of expressing […]

India’s Mission to Mars

Introduction NASA’s projected cost of its Mars mission stands at $679 million. In contrast, the Indian Space Research Organization’s (ISRO) Mars mission has spent $600 less to launch the same mission (Burke, 2013). Nevertheless, ISRO has been heavily criticized for its huge spending on this mission. Critics argue that this money should have been used […]

The Life Cycle of a Star

Introduction For millenniums, stars have fascinated the human race. In medieval times, these heavenly bodies were thought to possess mystical powers and some civilizations even worshiped them. This supernatural view was caused by the lack of information on the true nature of stars. Modern science has enabled man to study stars and come up with […]
