Did other stars reshape Earth’s orbit? Check out these amazing stellar encounters

[ad_1] Astronomers have uncovered a celestial revelation: stars passing near our solar system have wielded a profound influence on the orbit of Earth as well as those of its its planetary companions. This cosmic dance, detailed in a study titled "Passing Stars as an Important Driver of Paleoclimate and the Solar System's Orbital Evolution" published in The Astrophysical Journal Letters, challenges our understanding of Earth's history and even encompasses shifts in climate.Stellar Perturbations and Climate VariabilityNathan A. Kaib, Senior Scientist at the Planetary Science Institute, leading the research with contributions from Sean Raymond at the Laboratoire d'Astrophysique de Bordeaux, highlights the significance of these stellar perturbations. "Perturbations- a minor deviation in the...

Changes in Earth’s orbit may have triggered ancient warming event

[ad_1] A 6,000-year onset, coupled with estimates that 10,000 gigatons of carbon were injected into the atmosphere as the greenhouse gases carbon dioxide or methane. Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago that is considered an analogue for modern climate change, according to an international team of scientists. "The Paleocene-Eocene Thermal Maximum is the closest thing we have in the geologic record to anything like what we're experiencing now and may experience in the future with climate change," said Lee Kump, professor of geosciences at Penn State. "There has been a lot of interest in better resolving that history, and our work addresses important questions about what triggered the event ...
