ARE WE ALONE?

-

 Every single cellular, multicellular organism lives on planet earth. Technically we are not alone on planet Earth. Lots of animals, plants, and intelligent life are surrounding us. Every organism has its own brain thinking power, sense I mean every organism is unique in so many ways. 

Have you ever thought about interstellar life? I mean life beyond the earth and the solar system. see we know that life is there on Jupiter's moon but it is not intelligent life like us. 

So ARE WE ALONE IN THE UNIVERSE?

According to my opinion, the answer is we can’t find it yet. We don’t have that much technology yet we are now in progress! Until 1992 we didn't know that much about Exoplanets,  now we know there are approximately 3580 Exoplanets in space or we can say in the universe because of the great evolution in radio telescopes and spacecraft. 

The term Exoplanets are those planets were so many chances of finding life and the composition is Earth-like! so there might be chances to make another earth in simple language so we can live there! The plate tectonics, chemical composition, gravity, gravitational field, Stability, Density, pre-existing life, and so many aspects we have to understand during finding exoplanets.

In our own solar system Mars, Europa, Titan, and Enceladus are the best places to live. 

But on Mars chances of finding pre-existing life is much higher. 

See our Observational universe is 13.8 billion light-years old and its radius is 46.8 billion light-years approximately. so many old and newborn galaxies so many stars, planets, nebulae, black holes. so many old and newborn galaxies so many stars, planets, nebulae, black holes.

My opinion on this topic is straightforward: that there are so many galaxies and their respective solar system is there in the universe so there might be chances and a high probability we can say to find life. There are so many chances to find life on Exomoons also.


Dr.Enrico Fermi once said in one meeting that WHERE ARE THE ALIENS? Today we know this as Fermi Paradox. We have been searching for Alien Life for so many years. We are still searching for it. There is one equation
called the Drake Equation which also tells about the probability of finding life. The Drake equation says that The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy.



 Following is the The Drake Equation:-



 N=R* . fp . ne . fl  . fi . fc  . L


Where,

N  = number of civilizations with which humans could communicate                                            

 R* = The rate of formation of stars that are suitable for the development of intelligent life.

fp = The fraction of those stars with planetary systems.

ne = The number of planets per solar system that have an environment suitable for life.

fl = The fraction of suitable planets on which life actually appears.

fi = The fraction of life-bearing planets on which intelligent life emerges.

fc = The fraction of intelligent civilizations that develop a technology that releases detectable signs of their existence into space.

L = The length of time such civilizations release detectable signals into space.

Initially, the answer that came from this equation is that N ≈ L, and there were probably between 1000 and 100,000,000 planets with civilizations in the Milky Way galaxy. 

I’m eagerly waiting for my Exobrothers. I don’t know where are they but I can tell you that WE ARE NOT ALONE IN UNIVERSE?

Evidences for the Dark Matter

-

  Dark matter is known  as the “missing mass,” dark matter’s existence was first inferred by Swiss American astronomer Fritz Zwicky, who in 1933 discovered that the mass of all the stars in the Coma cluster of galaxies provided only about 1 percent of the mass needed to keep the galaxies from escaping the cluster’s gravitational pull.  In this blog we will discuss 5 different pieces of evidence for the existence of the dark matter  BENDING OF LIGHT Gravitational lensing:- The amount of bending is proportional to the mass of the object that causing the bending,  Light gets bent due to the mass of the object. In this image light from the distant galaxy is lensed due to galaxy clusters, so we get lensed images here on the earth. But we are getting an extra lensed image than usual but the Amount of bending is proportional to the mass of the object, so there is evidence of missing mass, We get the factor of the Dark matter here. We can derive the formula for this  As  ROTATIONAL CURVE The f

Omuamua -The Interstellar Object

  1I/2017 U1 'Oumuamua' is the scientific name of Omuamua   Omuamua was the most recent interstellar object detected while passing through the solar system. 1I/2017 U1 ‘Oumuamua, was discovered on October 19, 2017, by the University of Hawaii’s Pan-STARRS1 telescope, which is funded by NASA’s Near-Earth Object Observations (NEOO) Program, which finds and tracks asteroids and comets in Earth’s neighborhood. Initially, it was classified as a comet but after some observations like speed and direction of path no signs of cometary activity were revealed as it slingshotted past the Sun on Sept. 9, 2017, at a blistering speed of 196,000 miles per hour (87.3 kilometers per second).   Size, Shape, and specifications Omuamua was The first confirmed object from another star to visit our solar system, It was looking like a rocky body and somewhat cigar-shaped object, very weird straight and slim shape and its color was reddish hue due to effects of irradiation from cosmic rays over hundre

CONJUCTION - 21DECEMBER 2020

21 December-the day of the solstice- is the day where we saw the conjunction of Jupiter and Saturn.  But some curious minds will think that what is the conjunction?  In astronomy, a conjunction occurs when any two astronomical objects (such as asteroids, moons, planets, and stars) appear to be close together in the sky, as observed from Earth If two objects have the same right ascension or the same ecliptic longitude, they are considered to be in conjunction with one another. The planets regularly appear to pass each other in the solar system, with the positions of Jupiter and Saturn being aligned in the sky about once every 20 years. But What was special in this year’s conjunction? It’s been nearly 400 years since the planets passed close to each other in the sky, and nearly 800 years since the alignment of Saturn and Jupiter occurred at night, as it will for 2020, allowing nearly everyone around the world to witness this “great conjunction.” History of Jupiter and Saturn conjunction
