Stellar Nucleosynthesis

Image
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

Astronomy club Demonstration On ATL Inaugration

Image
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.

Lunar eclipse 2018: when to see the blood moon – and the science behind it

Image
Everything you need to know about Friday’s total lunar eclipse, from how to see it wherever you are in the world to why the moon turns red  A blood moon is coming!!!!! Weather permitting, get ready for a beautiful celestial sight on Friday 27 July and Saturday 28 July, when a total lunar eclipse will be visible from almost all parts of the world. The only people missing out this time are Greenland, Canada and the USA. From the India, this spectacular sight will last all evening. As the moon rises at 8:50 P.M. the eclipse will already be in its total phase and the moon will be a deep-red colour as it climbs into the sky. All you need is a clear view of the night sky. Your eyes are the best instrument to soak up the sight. If you happen to have a pair of binoculars to hand you can use them to range across the craters of the moon but that’s just icing on the cake. Best of all, you don’t need to wear special filters or protective glasses to view a lunar eclipse. Unlike a tota

dark nebula

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
