Unicorn: May Be The Closest Black Hole To Earth.

Image
  Monoceros Constellation. Monoceros is a faint constellation on the celestial equator. It is surrounded by Orion on the West, Gemini to the North, Canis Makor to the south, and Hydra to the east. It is generally best visible at latitudes between 75° and -90°. Alpha Monoceros which the brightest star, has a visual magnitude of 3.931. Beta Monocerotis a triple star system. What are wondering what are triple star systems? Well, the three stars form a fixed triangle, it was discovered by astronomer William Herschel in 1781, calling it “one of the most beautiful sights in the heavens”. Well, apart from the stars, this constellation has many more secrets to tell! Like, it contains the famous Rosette Nebula, the Cone Nebula, two Super-Earth exoplanets, two open clusters -such as M50 and the Christmas Tree cluster (named for its resemblance to a Christmas tree) and what not! Apart from these, astronomers have found evidence for a candidate black hole that exist in this constellation....

What Is A Black Hole?

  Timeline of Stars. Stars are massive fiery balls of burning gas but  this fierce display of burning fuels does not last forever. Eventually, a time comes when the star ends up all its fuel which powered the fusion. So the pressure due to burning of gasses also keeps decreasing as the time goes on. Then, the Gravity collapses the remaining matter together when the outward pressure of burning gasses is no more sufficient to counter balance the gravity of the star. For small stars (like our sun or the stars which don't have enough mass to undergo supernova) first bulge into a hot glowing red giant and then cools down as white dwarf where as for massive stars, what happens next is a display of extremes. First, the star explodes in a supernova, scattering most of its matter throughout the universe. This explosion is so bright that for a few days, the dying star outshines its entire galaxy. After the supernova explosion is over, the light fades and darkness returns and  the r...

Terraforming Mars, How Hard Would It Be?

Image
 As habitants of Earth, we have become quite aware of our planet's mortality, and for the most part, we’ve accepted it. Would that mean we need to accept humanity’s mortality? Or is it even possible to live the lives of our science fiction stories and have human colonies all over the universe? A good place to start would be our small red neighbour Mars. In this read, we will explore 5 questions and its answers on Terraforming Mars, including the challenges, the ethics, and if it's even possible to do so. Why is Mars an attractive planet compare to the others? First and foremost, Mars is the ideal candidate for expanding humanity simply because it is our closest neighbour, but the planet also has some other attractive features that make it ideal. Mars is actually on the border of the extended habitable zone, which means liquid water on the surface could be supported if the atmospheric pressure could be increased. This fact makes it the most Earth-like planet within our known sol...

Carrington Event - Geomagnetic Storm of 1859.

Image
On 28th of August, 1859, in the night the skies around the globe lit up with spectacular displays of light. In few places the sky glowed red as if it were  reflecting a huge wildfire. For almost a week skies around the globe illuminated so brightly that it was possible to read a newspaper at even at midnight. Everywhere, people gathered and gazed the sky, terrified and  in equal measure. The major chunk of people had no clue of what they were witnessing, and could only assume that it was a portent of the end of the world. Reports exist from many different countries of the strange phenomena that could be seen during the whole week which followed the 28th of August, 1859. In Boston, the sky glowed red to such a degree that many who witnessed it believed that there was a fire burning over the horizon, at least until the red transmuted to a vivid green. The effect was almost bewildering, and was witnessed with mingled feelings of a...

Are We Living In a Space Opera Universe?

Image
We humans are always excited to learn about planets, galaxies, stars, asteroids, and what’s there deep in space. This urge for exploration has led us to execute many successful space missions. These all have become possible due to technical advancements but the people had already imagined some stories and concepts set in space and those narratives are space operas. Let's look into our space opera universe which is made up of trillions of superclusters in which there is a tiny cluster called VIRGO supercluster, and a supercluster is made up of trillions of clusters among which there is a small cluster called  VIRGO cluster, a cluster is made up of several galaxies in which there is a galaxy called MILKY WAY, a galaxy is made up of several solar systems of which there is our solar system which has eight planets and a star called the sun, amongst these eight planets there our planet called EARTH where we are living. Millions of years ago, our universe took birth. From birth to now, it...
