“Understanding how Earth regulates climate both in the modern era but also in the distant past is critical for our understanding of planetary habitability,” said Noah Planavsky, a biogeochemist at Yale University. “This will help guide our search for life beyond our solar system and is an example of how the evolution of complex life fundamentally changed our planet.”
Welcome to today’s news from the Universe that has the capacity to provide clues to the mystery of our existence and adds a much needed cosmic perspective in our current Anthropocene Epoch.
“Our models show that there is a real possibility that Venus could have been habitable and radically different from the Venus we see today,” said Michael Way of The Goddard Institute for Space Science about Earth’s ‘twisted sister’ planet. “This opens up all kinds of implications for exoplanets found in what is called the ‘Venus Zone’, which may in fact host liquid water and temperate climates.”
In this week’s report we dive into the story of a giant asteroid the size of Pluto, crashing into Mars igniting an ancient climate catastrophe. As well as a mystery discovered at Mar’s south pole –an ancient object with vast climate implications .
Our Pale Blue Dot has produced a wealth of fascinating new stories the past few days –from when Earth had two moons to a major discovery in Antarctica’s seas.
“This is really an origin story; for the first time we can explain how all nearby star formation began,” says astronomer and data visualization expert Catherine Zucker a NASA Hubble Fellow at the Harvard Center for Astrophysics and Space Science Institute about the discovery that Earth sits in a 1,000-light-year-wide void surrounded by thousands of young stars.
