In those olden nights, when sky was clear and visible, unlike our present day fogged and tainted urban sky laden with many different kinds of pollutants, our ancestors would speculate and even aspire on the possibility of life on other planets, hoping to find a clue here and there, now and then, on the grand possibility that life exists, not just here on Earth, but elsewhere in the universe as well. And the search continued. For thousands of years, since the time we, the people, learned to reason and apply logic in our everyday existence, all of us at one point or another wondered about the possibility of extra-terrestrial life-forms, possibly even intelligent ones at it too. And with the application of science and steered by the blessings of modern day technologies, the search for life on other planets continues with a heightened energy that has opened up many incredible windows in the sky and made this ancient quest more thrilling. Any day now, there might just be that press conference by the NASA elites that would say, Ladies and Gentlemen, we are not alone in this Universe . In the meantime, let s notice a remarkable aspect about our own planet. The strangest thing about this 4.54 billion year old dear Earth of ours is that, whatever we need to survive and flourish as a species and as a civilization, all that can be found here on this magnificent blue planet. And this truly makes this 3rd planet from the Sun unique and so far, spectacularly, one of a kind. And given the astonishing significances of our planet, it was the ancients belief that our planet Earth was the 1 centre of the universe. But this idea, somewhat quite selfish, couldn t stand the test of time. How this revolutionary idea that Earth is not at the centre of the universe came to be is one of a fascinating one. It all began on January 7th, 1610, when the esteemed Italian astronomer Galileo Galilee aimed his telescope towards the planet Jupiter and noticed three small stars near the planet, one of which was off to the west and the other two were to the east, all lying in a straight line. The observation from the subsequent nights revealed that all three stars were now positioned on the west of Jupiter however still in a straight

  • Habitabilidade No Sistema Solar
    Jorge Martins Teixeira HABITABILIDADE NO SISTEMA SOLAR Departamento de Física e Astronomia. Faculdade de Ciências da Universidade do Porto. Ano de 2014 Prefácio O tema da existência de vida no sistema solar é extremamente interessante. Gente de todas as idades, formações escolares e profissões se questiona se estamos sós no Universo. E gente de todos os tempos. É um assunto inesgotável. Estar em cima deste planeta e ver aquelas pintinhas lá longe tão inacessíveis é sentir que estamos perante algo que nos ultrapassa completamente. Mas que é ao mesmo tempo extremamente fascinante. Isso mesmo tive oportunidade de constatar numas férias que passei no Alentejo quando estive presente no Andanças - basicamente uma série de pavilhões onde se aprende a dançar - pois quando me encontrava altas horas da noite a indicar aos meus colegas onde se encontrava a estrela polar, a posição da Via Láctea, e outros fenómenos astronómicos fui surpreendido por um grupo de umas dez pessoas, de todas as idades, que se apercebeu do que estava a fazer e propôs a realização de uma sessão de observação de astronomia naquele recinto. De pergunta a pergunta a olhar para o céu estrelado, os minutos passaram a mais de uma hora. Isto é, a juntar à dança propriamente dita não lhes parecia mal acrescentar as danças dos corpos celestes. Seria também interessante fazer uma pesquisa nos livros de divulgação científica quais aqueles que fazem da astronomia o seu principal tema. E dar o devido valor a estas matérias que têm sido um pouco subalternizadas no ensino por outras. E ir para o espaço é o nosso futuro.

  • Cosmological Aspects of Planetary Habitability
    Cosmological aspects of planetary habitability Yu. A. Shchekinov Department of Space Physics, SFU, Rostov on Don, Russia [email protected] M. Safonova, J. Murthy Indian Institute of Astrophysics, Bangalore, India [email protected], [email protected] ABSTRACT The habitable zone (HZ) is defined as the region around a star where a planet can support liquid water on its surface, which, together with an oxygen atmo- sphere, is presumed to be necessary (and sufficient) to develop and sustain life on the planet. Currently, about twenty potentially habitable planets are listed. The most intriguing question driving all these studies is whether planets within habitable zones host extraterrestrial life. It is implicitly assumed that a planet in the habitable zone bears biota. How- ever along with the two usual indicators of habitability, an oxygen atmosphere and liquid water on the surface, an additional one – the age — has to be taken into account when the question of the existence of life (or even a simple biota) on a planet is addressed. The importance of planetary age for the existence of life as we know it follows from the fact that the primary process, the photosynthesis, is endothermic with an activation energy higher than temperatures in habitable zones. Therefore on planets in habitable zones, due to variations in their albedo, orbits, diameters and other crucial parameters, the onset of photosynthesis may arXiv:1404.0641v1 [astro-ph.EP] 2 Apr 2014 take much longer time than the planetary age. Recently, several exoplanets orbiting Population II stars with ages of 12–13 Gyr were discovered.

    Draft version July 1, 2020 Typeset using LATEX twocolumn style in AASTeX62 The Gaia-Kepler Stellar Properties Catalog. II. Planet Radius Demographics as a Function of Stellar Mass and Age Travis A. Berger,1 Daniel Huber,1 Eric Gaidos,2 Jennifer L. van Saders,1 and Lauren M. Weiss1 1Institute for Astronomy, University of Hawai`i, 2680 Woodlawn Drive, Honolulu, HI 96822, USA 2Department of Earth Sciences, University of Hawai`i at M¯anoa, Honolulu, HI 96822, USA ABSTRACT Studies of exoplanet demographics require large samples and precise constraints on exoplanet host stars. Using the homogeneous Kepler stellar properties derived using Gaia Data Release 2 by Berger et al.(2020), we re-compute Kepler planet radii and incident fluxes and investigate their distributions with stellar mass and age. We measure the stellar mass dependence of the planet radius valley to +0:21 be d log Rp/d log M? = 0:26−0:16, consistent with the slope predicted by a planet mass dependence on stellar mass (0.24{0.35) and core-powered mass-loss (0.33). We also find first evidence of a stellar age dependence of the planet populations straddling the radius valley. Specifically, we determine that the fraction of super-Earths (1{1.8 R⊕) to sub-Neptunes (1.8{3.5 R⊕) increases from 0.61 ± 0.09 at young ages (< 1 Gyr) to 1.00 ± 0.10 at old ages (> 1 Gyr), consistent with the prediction by core-powered mass- loss that the mechanism shaping the radius valley operates over Gyr timescales. Additionally, we find a tentative decrease in the radii of relatively cool (Fp < 150 F⊕) sub-Neptunes over Gyr timescales, which suggests that these planets may possess H/He envelopes instead of higher mean molecular weight atmospheres.

We also migrated Academy from its separate server into SFI.org, so that the STARFLEET branding could be applied to Academy, and to eliminate the costs of an extra domain and web hosting. We had to close Glen’s unfinished projects that he left behind, and audit and retire those colleges that were not performing at minimum standards. We were not lacking in volunteers to direct those that were left. Survival Studies (COSS), a favorite among many students, was taken over by myself, the author of the first version of the college. The COSS has gone through a major rewrite and reformat. Long exams were divided into 25-point multiple choice or True and False exams. Three of the four schools are reopened, and the fourth will be open soon, with more exams to be added. Wherever an exam was split into 2 or more exams, the existing graduates was copied over with their grades and completion dates.
