Is Earth really exceptional?  A new book seems to reaffirm that notion.  But given the right conditions, primitive life may be a mere byproduct of biophysics.

As planets pass in front of their parent stars as viewed from Earth, they cause a tiny dip in the amount of starlight we ...

The planet is crumbling so fast due to bombardment from its star that it is losing a "moon's worth" of matter every million years. Soon, it is doomed to vanish entirely. The extrasolar planet ...

Problem is, even nearby earth-like planets are extremely difficult to detect. As a result, most of the extrasolar planets thus far detected are much bigger than tiny earths. They are extrasolar ...

WASP-121b is like nothing in the solar system, raining liquid metal and being puffy like a marshmallow. The origins of these ...

Hubble Space Telescope observations of white dwarf star G238-44 has shown that it is "consuming both rocky-metallic and icy ...

We search for extrasolar planets and determine their properties. We develop models that describe the atmospheres of the planets. We want to find out what makes a planet favourable to life. Through ...

Using data from the European Space Agency's Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia's ability to ...

Can we find another planet like Earth orbiting a nearby star? Extrasolar planets (exoplanets) have moved from being a novelty to a fundamental part of modern astronomy. Over 1500 exoplanets have been ...

Extrasolar planets contextualise the Solar System among a large number of planetary systems with very different properties. Many extrasolar planets show characteristics which are not realised in the ...

Skip to content viewer section. ABSTRACT I present a review of astrometric techniques and instrumentation used to search for, detect, and characterize extrasolar planets. First, I briefly summarize ...
