“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.”
Our Universe provided some fascinating news stories over the past few days, ranging from Antimatter Stars of the Milky Way to Can Early Dark Energy Save the Universe to Our Weird Solar System.
This week’s report from the Cosmos brings amazing stories ranging from What Existed Before the Big Bang to Forms of Consciousness We Can’t Recognize to World’s Scientists Share Their Expectations for the James Webb Space Telescope.
The James Webb Space Telescope team has fully deployed the spacecraft’s tennis-court-sized 70-foot sunshield, a key milestone in preparing it for science operations. On its month-long voyage to LaGrange Point 2, the Webb team began remotely deploying the sunshield Dec. 28, 2021, three days after launch.
We are on the cusp of a new epoch in the search for life beyond Earth. Sun-like stars represent just 15 percent of all stars in the Milky Way. And nearly half of those have binary star companions that suppressed the formation of planets. The search for Earth analogs around single, solar-type stars therefore covers a nearly insignificant fraction of all the outcomes in nature.
As the James Webb Space Telescope begins its month-long voyage to LaGrange Point 2, several of the planet’s leading astronomers and scientists have shared their expectations and hopes for this epoch event in human history with The Daily Galaxy.
