The habitable zone as a research area focuses on defining and characterizing the circumstellar regions where planetary surface conditions could permit stable liquid water, given realistic atmospheric and geophysical constraints. This field integrates stellar astrophysics, planetary climate modeling, atmospheric radiative–convective equilibrium, and orbital dynamics to compute inner and outer habitable zone boundaries as functions of stellar type, luminosity evolution, and planetary properties. Researchers investigate feedbacks such as the carbonate–silicate cycle, cloud processes, greenhouse limits, and water loss, and extend the concept to temporal (continuously habitable) zones and system-level habitability, including multiplanet interactions and stellar activity effects on long-term planetary climate stability.
What if humanity's search for life on other planets returns no hits? A team of researchers led by Dr. Daniel Angerhausen, a Physicist in Professor Sascha Quanz's Exoplanets and Habitability Group at ETH Zurich and a SETI ...

When a mudflat crumbles on Earth, or an ice sheet splinters on one of Jupiter's moons (Europa), or an ancient lakebed breaks on Mars, do these fractures follow a hidden geometric script? Could similar patterns on another ...

Astronomers have found some pretty wild exoplanets. Some are balls of lava the temperature of hell, one is partially made of diamond, and another may rain molten iron. However, not all exoplanets are this extreme. Some are ...

The hunt for aliens goes hand in hand with the hunt for habitable planets. Astronomers are on the hunt for exoplanets with atmospheric chemicals that could be a sign of an advanced civilization. These chemicals, known as ...

It has been thought that plate tectonics were a significant factor in the shaping of our planet and the evolution of life. Mars and Venus don't experience such movements of crustal plates, but then the differences between ...

Potentially habitable exoplanets are so incredibly common that astronomers have started to consider more unusual situations where life might arise. Perhaps life can be found on the moon of a hot Jupiter or lingering in the ...

For now, the future of life on Earth is in human hands. But after the anthropocentric era, the situation starts to get dicey. The sun's luminosity is increasing over time, about 1% every 110 million years, so the Earth's ...
