Cosmic Rays Will Kill Us Anyways? (eventually) - #15 – Om Gohil – 20542740 - High energy science (astrophysics, nuclear medicine) and its processes in the Extreme Universe crucially informs the study of life in the Universe. Supernovae distribute the products of stellar burning, which are the raw materials of life. However, don't stand too close: supernovae adversely affect nearby life-friendly planets, bathing them in high-energy radiation, cosmic rays, and ejecta. Gamma ray bursts (GRBs) too, primarily via their impact on Earth's ozone layer, are plausibly responsible for the irradiation and destruction of surface sea life, causing mass extinction events. Active quasars and galaxies emit enough extreme and high energy radiation to strip planetary atmospheres at kiloparsec-scale distances. New observational data and improved theoretical models of the high energy (Extreme) Universe will illuminate the history of life on Earth (and Universe?), and aid the search for potentially life-hosting planets in our Galaxy. The extreme universe puts bounds on the spaces in which life - and particularly complex life - can exist. This leads to a complementary approach to the study of life in the Universe. Traditional astrobiology concentrates on finding places with a high prior probability of finding life ('follow the water'). By studying the extreme universe, we can instead start to exclude parts of the Universe from consideration - Reviewing the nature of scientific research, paying particular attention to complexity and uncertainty in science - Identify specific examples from the published literature to support your ideas - Consider the complexity of your chosen ccs, describing the nature of the problem and identifying key considerations in solving a problem - Use figures and tables where appropriate and sections can be separated by using sub-headings.

Things to talk about:  Glossary of terms o Supernovae o Ejecta o Gamma ray bursts o Ozone layer o Quasars o Kiloparsec o Habitable  What is the problem exactly? o Are supernovae in fact adversely affecting nearby-life friendly planets by energy radiation? o How harmful is the deterioration of the ozone layer to the human species o Why should we worry about quasars if they’re so far away from us? o Will they eventually affect habitable planets?  Supernovae adversely affecting nearby life-friendly planets, bathing them in high- energy radiation, cosmic rays and ejecta o What are supernovae o What planets are most similar to earth in terms of composition o Which planets from those similar (or not) are most affected by the high- energy radiation o  Gamma ray bursts (GRBs) also affecting nearby life-friendly planets, as well as it’s primary impact on the earth’s ozone layer, which is leading to the destruction of surface sea life, causing mass extinction events  Active quasars and galaxies emit enough extreme and high energy radiation to strip planetary atmospheres at kiloparsec-scale distances  Determining how a planet is habitable instead of the typical “follow the water” method (mars, I think) Structure: - Is the structure and organisation of the document sufficient? Writing Style: - How is the writing style (errors in grammar, spelling etc)? Content/Depth: - How much material has been reviewed and how detailed? References: - What is the quality of the references and citations?

Conclusion: - Conclusion has basis for methodology report - Has all relevant literature been discussed in order to build up case for methodology (2 nd assessment)?
