Gravitational lensing 

What is gravitational lensing ?


According to the special theory of relativity objects with higher mass bends the space time ...if you don't have a clear idea about space time  i will clarify about that concept in my upcoming articles...

Well light contains particles named as photons...photon particles have a minor mass ...so when a light ray moving through the space time and meets a bended space time curve..eventually the light ray bends with it as well...this scenario named as the gravitational lensing.... this is the most simplified  clarification for gravitational lensing....




So why gravitational lensing was important for space exploration ?



Well scientist use the gravitational lensing method to explore deep space....the above picture contains galaxies which was even 13 billion light years away from earth....

The benefit of gravitational lensing was...with the affect of gravitational lensing the brightness of a light ray will get increased....so  we can explore light particles which we cannot see for several reasons ( dust clouds etc )...

Recently nasa jws telescope  used this method to capture galaxy images which was located 13.5 billion light years away named as " GN - Z11 "

So if you interested about rocket engineering , Astrophysics and astronomy just keep in touch...cheers ❤️

  I n the vast expanse of the universe..amidst the myriad stars and galaxies , like black holes ....The enigmatic giants that challenge our understanding of the cosmos....Born from the remnants of massive stars..... These celestial objects possess gravitational forces so strong that nothing.....not even light can escape their grasp.......In this article we embark on a journey to discover the mysterious behavior of black holes....exploring their formation , properties and profound impact on the fabric of the universe...... FORMATION AND EVOLUTION ....... B lack holes are formed through the gravitational collapse of massive stars at the end of their life cycles.....When a star exhaust its nuclear fuel , it can no longer support its own mass against gravity.... Leading to  cataclysmic collapse.....During this process the star's outer layers are  expelled into space in a brilliant supernova explosion...While its core collapses inward.....forming a dense core known as a neutron star or

  BINARY STARS..... Binary stars , a celestial phenomenon where two stars orbit around a common center of mass.....This mind blowing system have captured the imagination and attention of astronomers and stargazers alike for decades and centuries..... This captivating cosmic ballet involves a dynamic interplay of gravitational forces , shaping the destiny of these stellar pairs....... In this article we will delve into the fascinating world of binary stars , exploring their types , formation and the crucial role they play in understanding the universal laws.....               ( WILLIAM HERSCHEL ) The binary star system was first observed and identified by the german british astronomer SIR. William Herschel.....Apart from binary stars scientist have observed star systems that consist three or more stars together....And those types of systems were named as multiple stars.....Scientist estimates that in the observable  universe 50% or more of the stars can be binary and 10% of it can be mu

  Delta-V Rockets-Pioneers of Space Exploration. Introduction Have you ever wondered how rockets travel through the vastness of space? How do they change their paths, speed up, slow down or enter orbits around planets? The secret lies in a fascinating concept called Delta-V. Lets dive into the world of Delta-V rockets and explore how they are the unsung heroes of space exploration. What is Delta- V ? Delta-V stands for "change in velocity." In the context of space travel. It refers to the amount of effort required to change a spacecrafts speed or direction. Think of Delta-V as the fuel gauge for a rockets journey. The higher the Delta-V the more energy a rocket needs to maneuver in space. Why Delta-V is Crucial ? When a spacecraft launches from Earth it must overcome gravity and achieve a high enough speed to reach orbit. This requires a significant amount of Delta-V. But the journey does not end there. To travel to the Moon, Mars, or beyond a spacecraft needs additional Delt
