Earth-like planetshabitable zoneplanet formationHabitability varies dramatically with location and time in the universe. This was recognized centuries ago, but it was only in the last few decades that astronomers began to systematize the study of habitability. The introduction of the concept of the ...
The exploration of habitable planets outside the solar system is one of the key frontiers of fundamental research in astronomy. It will offer crucial clues to the issues such as "Are we alone in the universe?" and "How can planets become the cradle of life?" according to Ji Jianghui, a...
Astronomers at the University of Auckland claim that there are actually around 100 billion habitable, Earth-like planets in the Milky Way. There are roughly 500 billion galaxies in the universe, meaning there is somewhere in the region of 50,000,000,000,
Earth orbits within the Sun's habitable zone, and it certainly had the right conditions and ingredients for life to develop and thrive. Even at its best, though, when we consider all the planets out in the galaxy, Earth may only bemoderatelyhabitable. In anew stud...

It’s Not Always About Other Planets One other outcome of the Wordsworth-Cockell research points out benefits for other fields of study. For example, life support for humans in space. That would allow for the use of biotechnology in medicine, food, habitat construction, and spacecraft propulsi...

Ever since Carl Sagan first predicted that extraterrestrial civilizations must number in the millions, the search for life on other planets has gripped our imagination. Is Earth so rare that advanced life forms like us - or even the simplest biological organisms - are unique to the universe? "...
When you’re thinking about a new home among the stars, or trying to seek out new life in the Universe, look for planets in the habitable zone. As we’ve seen, it’s only a rough guideline. You probably want to check out the place first and make sure it’s truly liveable before ...
