terrestrial, rocky
planet with an iron core, so we thought it would work the same way.
In the Solar System, the asteroid belt contains the leftover building blocks for the
terrestrial planets Mercury, Venus, Earth, and Mars, so planetary scientists study the asteroids to gain a better understanding of

planets are formed.
The Red
Planet has never been a tropical paradise, but after investigating

«In many ways, the atmospheric studies we're doing now on these gaseous «hot Jupiter» kinds of
planets are test beds for
how we're going to do atmospheric studies of
terrestrial, Earth - like
planets,» said Thomas Beatty, assistant research professor of astronomy at Penn State and the lead author of the study.
Astronomers were at a loss to explain
how such
planets formed and whether there was a continuum between rocky
terrestrial «super-Earths» and gassy «mini-Neptunes.»
«This confirms our view of
how the Earth cooled and became habitable,» says Valley, a geochemist whose studies of zircons, the oldest known
terrestrial materials, have helped portray
how the Earth's crust formed during the first geologic eon of the
planet.

planets in our solar system — including our own!
Our study emphasizes the need for careful analysis when considering
how the atmospheric dynamics of a synchronously rotating
terrestrial planet may differ from our own.

terrestrial planets to get a better understanding of
how these large eruptions took place, and
how fast and
how long they lasted,» Davies said.
It speaks to the very heart of trying to understand
how life may have evolved not just on earth but on other
terrestrial bodies both in our own solar system and indeed around other stars that have
planets that lie in the so - called «habitable zone» (where liquid water can exist on the surface).
«We are using Io as a volcanic laboratory, where we can look back into the past of the
terrestrial planets to get a better understanding of
how these large eruptions took place, and
how fast and

If CO2 levels on
planet Earth also lag the cooling periods, then
how can it be that CO2 levels are causally related to
terrestrial heating periods at all?
