FATE OF STARS MASSIVE THAN SUN

FATE OF STARS MASSIVE THAN SUN

Every star has a finite fuel with which it burns the gases present inside it and gives off luminosity as the energy obtained from the reactions. However, a star more massive than the sun will not always have the same fate as the sun. They all go on different paths…

SCIENTIFIC METHOD

SCIENTIFIC METHOD-ASTRONOMY OR SCIENTIFIC LAB?

The Scientific method is defined as a method of procedure which explains how to characterize natural science through a sequential systematic observation, measurement, and experiment, followed by the formulation, testing, and modification of hypotheses. Astronomy, as a scientific method, is defined as a systematic analytical observation of various celestial and…

BLACK HOLES

BLACK HOLE: A MYSTERY!

“Black holes are where God divided by zero.” – Albert Einstein What is a Black hole? A black hole is defined in simple terms as space that is dense and has a strong gravitational force such that even light cannot escape and hence the name “Black Hole.” The astronomers have…

EXOPLANETS HOW TO FIND THEM

EXOPLANETS: HOW TO FIND THEM?

Exoplanets are extraterrestrial planets that orbit a planet other than the sun. They are very difficult to see with naked eyes. A total no of 4000 exoplanets has been found till now using a wide range of methods with the help of ground-based and space-based telescopes. Astronomers have been hunting…

Spitzer Space Telescope also is known as Space Infrared Telescope Facility, is one of the most popular space telescopes to have been launched into space till now

SPITZER SPACE TELESCOPE

Spitzer Space Telescope also is known as Space Infrared Telescope Facility, is one of the most popular space telescopes to have been launched into space till now. Launched in 2003, the mission was planned for 2.5 years with a pre-launch expectation of a period lasting up to 5 years till…

ASTEROIDS

ASTEROIDS: THE RELICS OF THE SOLAR SYSTEM

Asteroids are the remnants of the materials left after the formation of the solar system about 4.6 billion years ago. They are small planetary bodies sometimes referred to as minor planets. Most of them can be found orbiting the sun between the orbit lines of Jupiter and Mars within the…

BIG BANG THEORY

BIG BANG THEORY

The Big Bang Theory is a cosmological model that explains the large-time scale evolution of the observable universe. The model explains how Universe evolved and expanded from an initial point with extremely high temperature and density to how we observe it today. The Universe expanded from this point of singularity…

TIMELINE OF BIG BANG-INFLATION AND BARYOGENESIS

TIMELINE OF BIG BANG-INFLATION AND BARYOGENESIS

Due to a lack of observational or physical evidence of the astronomical data of the time of the Big Bang, there is much speculation amongst scientists as to the true perplexing nature of space and time at that time. Present computer models and speculations depict an environment where the universe…

TIMELINE OF BIG BANG COOLING

TIMELINE OF BIG BANG: COOLING

With the advent of Cosmic inflation, the Universe expanded at a speed faster than the speed of light resulting in an instantaneous increase in the volume of space by 1078.  Due to this, the Universe continued to decrease in temperature and density, and therefore the average energy per particle was…

TIMELINE OF THE BIG BANG: SINGULARITY

TIMELINE OF THE BIG BANG: SINGULARITY

According to the current Big Bang Model, it suggests that the Universe was dense and small at the beginning and since then it has been expanding rapidly due to inflationary pressure. We will go through those different phases of the formation of the Universe from the occurrence of Big Bang…
