Clouds, which are common features in Earth's atmosphere, form in atmospheres of planets that orbit other stars than our Sun, in so-called extrasolar planets or exoplanets. Exoplanet atmospheres can be chemically extremely rich. Exoplanet clouds are therefore composed of a mix of materials that changes throughout the atmosphere.

Habitable Zones in Binary Star Systems: A Zoology
Several concepts have been brought forward to determine where terrestrial planets are likely to remain habitable in multi-stellar environments. Isophote-based habitable zones, for instance, rely on insolation geometry to predict habitability, whereas ...

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 environment for internal maintenance and activity, and capable of

Evolution of Exoplanets and their Parent Stars [PDF]
Studying exoplanets with their parent stars is crucial to understand their population, formation and history. We review some of the key questions regarding their evolution with particular emphasis on giant gaseous exoplanets orbiting close to solar-type ...

Disintegrating Rocky Exoplanets [PDF]
We discuss a new class of exoplanets that appear to be emitting a tail of dusty effluents. These disintegrating planets are found close to their host stars and have very hot, and likely molten, surfaces. The properties of the dust should provide a direct probe of the constituent material of these rocky bodies.

The Habitability of the Galactic Bulge
We present a new investigation of the habitability of the Milky Way bulge, that expands previous studies on the Galactic Habitable Zone. We discuss existing knowledge on the abundance of planets in the bulge, metallicity and the possible frequency of ...

The Observational Case for Jupiter Being a Typical Massive Planet
We identify a subsample of the recently detected extrasolar planets that is minimally affected by the selection effects of the Doppler detection method.

On homogeneous statistical distributions exoplanets for their dynamic parameters
Correct distributions of extrasolar systems for their orbital parameters (semi-major axes, period, eccentricity) and physical characteristics (mass, spectral type of parent star) are received. Orbital resonances in extrasolar systems are considered.

VISIBLE AND INFRARED TELESCOPES IN DETECTION OF EARTH-LIKE EXOPLANETS
Object and purpose: The study examines the balance of resolving and light-harvesting (penetrating) abilities of filled and sparse aperture telescopes in direct detection of terrestrial exoplanets.
