  The vastness of the cosmos has always been a realm of curiosity, with countless stars harboring their own planetary systems. One such fascinating system belongs to the star HR 8799 , a landmark in exoplanetary research. Recently, the James Webb Space Telescope (JWST) added a new chapter to this cosmic saga by detecting carbon dioxide (CO₂) in the atmosphere of one of HR 8799's exoplanets. This discovery not only showcases the advanced capabilities of the JWST but also opens up intriguing questions about the composition and evolution of exoplanetary atmospheres. The HR 8799 System: An Overview HR 8799 is a young, massive A-type star located approximately 133 light-years away from Earth in the constellation Pegasus. Known for being one of the first star systems with directly imaged exoplanets, HR 8799 hosts a dynamic family of four gas giants: HR 8799 b, c, d, and e. These exoplanets are massive, ranging from 5 to 10 times the mass of Jupiter, and they orbit their parent star at d...

Gazing into the inky expanse of space, we encounter countless stars, each with its own story. But nestled amongst the familiar and predictable, there exists a celestial oddball: KIC 8462852 , better known as Tabby's Star or the delightfully blunt "WTF Star" . This F-type main-sequence star, similar to our Sun but slightly larger, has become an enigma due to its bizarre dimming behavior. Unlike the well-understood dips caused by transiting planets, Tabby's Star exhibits dramatic and irregular drops in brightness, sometimes by a staggering 20%. This unpredictable dimming has astronomers scratching their heads and proposing a multitude of theories to explain this cosmic light show. The Usual Suspects: Why Tabby's Star Plays Hide and Seek Before diving into the fantastical, let's explore some more grounded possibilities for the erratic dimming: Planetary Leviathan on a Chaotic Orbit: Imagine a behemoth of a planet, 1000 times Earth's mass , with a wildly irr...

This blog will open your mind, we have been searching for aliens for the last many years and trying to talk to them, but till date we have not been able to contact them, are they aliens? Or are we alone in this universe? If aliens want to contact us, in which language will we talk to them?, Will they also have radio technology?, Will they also speak English?, Will they also have the same technology as us?, Will they have time for them? And space will be a dimension?, Will they know the principles of gravity and relativity?, We have created all these principles of the universe, then how can aliens know this? Are there aliens in this universe? Our universe is 13.8 billion years old, and it is spread over about 97 billion light years, there are millions of galaxies and billions of planetary systems in this universe, and there are countless planets in it, and we live in one of these planets. So can't there be any other planet like our Earth where life is possible? If we think practical...
