Sentences with phrase «planetary habitability as»

This has strong implications for astrobiology and planetary habitability as any putative life forms near the surface would be exposed to large radiation doses capable of sterilizing the top ~ 20 cm of the Martian subsurface (Simonsen & Nealy 1993; Mileikowsky et al. 2000; Pavlov et al. 2002; Dartnell 2011; Dartnell et al. 2007a, 2007b, 2010).

In November a team led by Washington State University astrobiologist Dirk Schulze - Makuch devised the Planetary Habitability Index, or PHI, a scoring system for distant worlds that measures their suitability for any kind of life, not merely life as we know it.

Bean and Kempton, meanwhile, are interested in detailing what a statistical census of biologically significant gases such as oxygen, carbon dioxide and ozone could reveal about planetary habitability.

The research team looked at some of these as examples, and studied the evolving nature of planetary habitability over astronomical and geological time.

Thus we have three stars and possible planets at markedly different stages of development, giving us the ability to take a deeper look into flare activity on M - dwarfs as they age, and to assess flare effects on planetary habitability, assuming Barnard's Star and Ross 154 do have planets.

Secondly: «The Planetary Habitability Index is based -LRB-...) appropriate chemistry, and the potential for holding a liquid solvent,» as the paper's abstract notes.

Especially if it's linked with other processes that can help habitability such as CME avoidance and increased planetary magnetic field strength.

The Planetary Habitability Index is based on «the presence of a stable substrate, available energy, appropriate chemistry, and the potential for holding a liquid solvent,» as the paper's abstract notes.

As research into planetary habitability continues, through theory as well as observations, we will indeed continue to observe how even basic physical principles can manifest in very different ways on these alien worldAs research into planetary habitability continues, through theory as well as observations, we will indeed continue to observe how even basic physical principles can manifest in very different ways on these alien worldas well as observations, we will indeed continue to observe how even basic physical principles can manifest in very different ways on these alien worldas observations, we will indeed continue to observe how even basic physical principles can manifest in very different ways on these alien worlds.

The prospects for the habitability of M - dwarf planets have long been debated, due to key differences between the unique stellar and planetary environments around these low - mass stars, as compared to hotter, more luminous Sun - like stars.

(i) origin and evolution of planetary systems; (ii) origins of organic compounds in space; (iii) rock - water - carbon interactions, organic synthesis on earth, and steps to life; (iv) life and habitability; (v) biosignatures as facilitating life detection.

The key science question for citizens and their representatives is not whether most recent warming is man - made but whether climate change, as Al Gore HAS put it, is a «planetary emergency... that threatens the survival of civilization and the habitability of the Earth.»

Three - dimensional (3D) planetary general circulation models (GCMs) derived from the models that we use to project 21st Century changes in Earth's climate can now be used to address outstanding questions about how Earth became and remained habitable despite wide swings in solar radiation, atmospheric chemistry, and other climate forcings; whether these different eras of habitability manifest themselves in signals that might be detected from a great distance; whether and how planets such as Mars and Venus were habitable in the past; how common habitable exoplanets might be; and how we might best answer this question with future observations.
