Exoplanet research has shown an incessant growth since the first claim of a hot giant planet around a solar-like star in the mid-1990s. Today, the new facilities are working to spot the first habitable rocky planets around low-mass stars as a forerunner f... see more

Gravitational microlensing finds planets through their gravitational influence on the light coming from a more distant background star. The presence of the planet is then inferred from the tell-tale brightness variations of the background star during the ... see more

The fields of astronomy and astrophysics are currently engaged in an unprecedented era of discovery as recent missions have revealed thousands of exoplanets orbiting other stars. While the Kepler Space Telescope mission has enabled most of these exoplanet... see more

Bas van Fraassen defende que a verdadeira função dos instrumentos óticos é produzir imagens. Ainda assim, o produto de um telescópio seria diferente daquele de um microscópio, pois nesse segundo caso não é possível investigar empiricamente as relações geo... see more

We start with a brief description of the Alpha Centauri system and its main characteristics. Afterwards, we carry out calculations of several habitability metrics, such as the ? biological productivity and photosynthesis rates, in the oceans of the hypoth... see more

In clause necessity of formation of a spiritual picture of the world, anthropocosmos at young generation at the present stage of development much crisis world and, including, the Ukrainian society is proved. In the article the necessity of formation of an... see more

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 for follow-up habitability assessment. The classical HZ d... see more

Our understanding of extra-solar planet systems is highly driven by advances in observations in the past decade. Thanks to high precision spectrographs, we are able to reveal unseen companions to stars with the radial velocity method. High precision photo... see more
