'In November 2013, astronomers using the Kepler Space Mission data reported that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of sun-like stars and red dwarfs within the Milky Way Galaxy'. This quote from Wikipedia really fires up the imagination -...
根据下文“For example, when an exoplanet moves between its star and us, it causes a small drop in the star’s brightness. Measuring this drop is the transit (凌日) method of discovery. NASA’S Kepler space telescope has discovered many exoplanets this way.”(例如,当一颗系外行星在它的恒星...
TOI-1136 is a dwarf star in theMilky Waygalaxy more than 270 light-years from Earth, which is considered nearby, as the Milky Way is 100,000 light years in diameter. There are sixconfirmed planetsorbiting the star, and scientists strongly suspect the presence of a seventh. “Because few s...
In 2015 NASA's Kepler space telescope found its first Earth-sized planet in a "habitable"(宜居的)zone. This is the distance from a star where surface temperatures of a planet wouldn't be too hot or too cold for liquid water. So far, only a small part of our galaxy, the Milky Way,...
exoplanets are the planets that orbit around other stars located outside our solar system. exoplanets are also called extrasolar planets. all the stars have at least 1 planet revolving around them. most of the exoplanets discovered so far are located in the milky way galaxy. the first ...
After detecting the first exoplanets in the 1990s it has become clear that planets around other stars are the rule rather than the exception and there are likely hundreds of billions of exoplanets in the Milky Way alone. The search for these planets is now a large field of astronomy. Credit...
There are a few trillion planets in this far away elliptical galaxy. They appear to be ‘rouge’ planets not orbiting any star, but roaming free around the lens galaxy. Astrophysicists at University of Oklahoma have found multitudes of planets beyond the Milky way galaxy. This is the first ...
Currently, the most accurate measurements of stars come from theEuropean Space Agency’s Gaia mission, a space-based observatory that is designed to precisely measure and map the properties and paths of stars in theMilky Way. In 2016, Gaia’s measurements of Kepler-854 were not yet available....

In research recently published inAstrophysical Journal Letters, Krijt and fellow UChicago scientists conclude thatlifeforms, such as bacteria or single-cell organisms, could travel through the newly discovered TRAPPIST-1—an unusual solar system that presents an exciting new place in the Milky Way to...
