To be habitable, a world (planet or moon) does not need to be located in the stellar habitable zone (HZ), and worlds in the HZ are not necessarily habitable. Here, we illustrate how tidal heating can render terrestrial or icy worlds habitable beyond the stellar HZ. Scientists have developed a language that neglects the possible existence of worlds that offer more benign environments to life than Earth does. We call these objects "superhabitable" and discuss in which contexts this term could be… 
In Search for a Planet Better than Earth: Top Contenders for a Superhabitable World
It is argued that there could be regions of astrophysical parameter space of star-planet systems that could allow for planets to be even better for life than the authors' Earth and potentially superhabitable planets may deserve higher priority for follow-up observations than most Earth-like planets.
Risks for life on habitable planets from superflares of their host stars
We explore some of the ramifications arising from superflares on the evolutionary history of Earth, other planets in the Solar system, and exoplanets. We propose that the most powerful superflares

The aim of our study is to explore the possible existence of Earth-mass planets in the habitable zone of 55~Cancri, an effort pursued based on detailed orbital stability simulations. This star is
Another Earth 2.0? Not So Fast.
It should be clearly communicated to the public that the authors are probably still many years away from having the technological capability to detect an Earth-like planet or Earth 2.0 with adequate certainty.
The Astrobiology of Alien Worlds: Known and Unknown Forms of Life
Most definitions of life assume that, at a minimum, life is a physical form of matter distinct from its environment at a lower state of entropy than its surroundings, using energy from the
Dynamical considerations for life in multihabitable planetary systems
Inspired by the close-proximity pair of planets in the Kepler-36 system, we consider two effects that may have important ramifications for the development of life in similar systems where a pair of
Age aspects of habitability
Abstract A ‘habitable zone’ of a star is defined as a range of orbits within which a rocky planet can support liquid water on its surface. The most intriguing question driving the search for
Formation, habitability, and detection of extrasolar moons.
It is shown that natural satellites in the range of 0.1-0.5 Earth mass are potentially habitable, can form within the circumplanetary debris and gas disk or via capture from a binary, and are detectable with current technology.
The Inner Solar System's Habitability Through Time
Earth, Mars, and Venus, irradiated by an evolving Sun, have had fascinating but diverging histories of habitability. Although only Earth's surface is considered to be habitable today, all three
A More Comprehensive Habitable Zone for Finding Life on Other Planets
The habitable zone (HZ) is the circular region around a star(s) where standing bodies of water could exist on the surface of a rocky planet. Space missions employ the HZ to select promising targets
