A super-Earth planet that dips in and out of its star's habitable zone has been discovered just 19.7 light-years away. The planet, known as HD 20794d, gets farther out from its star than Mars is ...

For stars such as the sun or HD 20794, it can extend from 0.7 to 1.5 astronomical units (AU), encompassing not only the orbit of the Earth but also that of Mars in the case of the sun. The ...

A newly confirmed exoplanet around a nearby sunlike star might be astronomers’ best chance yet to look for life beyond the ...

An international team, including the UNIGE, has discovered a super-Earth that will enable astronomers to test new hypotheses ...

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.

While Earth and Mars have relatively circular orbits, HD 20794 d’s path changes its distance from the star significantly over a 647-day cycle. If water exists on HD 20794 d, it might freeze when the ...

“Instead of following a relatively circular orbit, like the Earth or Mars, HD 20794d follows an elliptical trajectory with large changes in the distance to its star during its revolution.” “The planet ...
