Element Origins After the Big Bang, the ordinary matter in the Universe was composed primarily of just two elements: hydrogen and helium. Currently, there are a wide range of elements, from argon to zirconium. These more complex elements were nearly all produced via stellar evolution processes. The formation of new elements is called nucleosynthesis . Below, I have describe the basics of the chemistry of the Universe and how it has changed over time. Big Bang Nucleosynthesis The star-forming region 30 Doradus. The blue stars are massive, hot, young stars. They have formed in a cluster out of gas and dust. (Credit: NASA, ESA, HST WFC3) When the Big Bang occurred approximately 14 billion years ago, the Universe was very hot and dense. Over time, the Universe expanded and cooled down. Approximately 0.001 seconds after the Big Bang, particles (e.g., protons and neutrons) began to fuse together to form atomic nuclei, dubbed nuclear fusion . Nuclear fusion process
On the occasion of the inaugural ceremony of ATL, Astronomy club got a chance to showcase our skills and knowledge about space and space related sciences where we presented hydro rockets, live meteoroid composition , exoplanet weight composition and we gave other others a chance to use see through our MISO(our beloved telescope) which was modified with an inbuilt screen with various star gaze indicators.
Dark Nebula Nebulas are glowing clouds of dust and gases which are present in this vast multiverse .... Unlike other nebulas which are luminous there are nebulas which are dark and completely opaque known as absorption nebula or dark nebula ... A dark nebula is a type of nebula that is so dense that it conceals the light from celestial objects behind it, such as background stars and emission or reflection nebula. The extinction of the light is caused by dust molecules forming dense clouds. Dark nebulas are generally coated with frozen carbon monoxide and nitrogen, which effectively block the passage of light at visible wavelengths. Also present are molecular hydrogen, atomic helium, C 18 O (CO with oxygen as the 18 O isotope), CS, NH 3 (ammonia), H 2 CO (formaldehyde), c-C 3 H 2 (cyclopropenylidene) and a molecular ion N 2 H + (diazenylium), all of which are relatively transparent. Due to presence of these gases these giant clouds are so dense and op
