When a person thinks of a telescope, he may subconsciously attach other words to it, words like planets, the sky or the solar system. But even Hans Lippershey – the person associated with the invention of said device in 1608 – may not have been aware that the simple telescope can be taken into a […]
It was in 1913 when a radio-chemist named Frederick Soddy first suggested the existence of isotopes. He noticed that the periodic table of elements only allowed for 11 elements ranging from uranium to lead. However, several types of atoms which differ in radioactive properties can still occupy the same place in the table.
JPL (Jet Propulsion Laboratory) is a research and development field center in Pasadena, California. Funded by the federal government under the management and operation of Caltech under contract with NASA, the primary function of JPL is the construction and also the operation of robotic spacecraft for planetary, Earth-orbit and other astronomy missions.

Each star has its own movement. This is the simplest way to describe a heliacal rising. Heliacal rising is a phenomenon by which a star becomes visible after being behind the Sun for a certain period of time. Just before sunrise, on the event of a heliacal rising, the star will shine above the eastern
A jet or jet stream is a very fast current of wind found high in the atmosphere of some planets including our own. A jet usually is a westerly wind, flowing from the west to the east, its path typically meandering. It’s very much like a river or an ocean current, often as fast as
If you recall your science lessons from school, you know that the earth is surrounded by several layers of air called the atmosphere, as do the other planets in the solar system. It is what allows us to breathe; it lets breathable air circulate within the boundaries it creates and even protects us from objects
The Last quarter moon is basically the precise point of the Moon parading the Sun on the final arc of the lunar process. At this point the moon looks half-lit or illuminated. The moon takes on the shape of a pie sliced in half. The Last quarter moon rises at around the time of midnight,
Interference in astronomy has a different perspective compared to the literal definition of the term. This word refers to light, radio or sound waves having differences or interruptions and can be a sign of activity in a certain part of a system, star or galaxy. There are mainly two types of wave interference, which are
To convert an atom or molecule into an ion via the process called ionization, charged particles like an electron or other ion must either be added or removed (though this is not to be confused with the chemical process called dissociation). To produce a positively charged ion, an electron which has bonded to a molecule
If humans have a life cycle, so do the stars. Not all stars were formed at the same time. Some are just beginning to shine and some are starting to die. Ejnar Hertzsprung and Henry Norris Russell created a diagram helps in understanding the lives of the stars.
