Key Points
The newly discovered planetary system consists of a white dwarf about half the mass of our sun and an Earth-like planet in an orbit twice the size of Earth's current path around the sun...
In a groundbreaking discovery, astronomers from the University of California, Berkeley have identified an Earth-sized planet orbiting a white dwarf star approximately 4,000 light-years away in the Milky Way galaxy...
This finding, published in the journal Nature Astronomy, offers a glimpse into a possible future scenario for our own solar system...
Lead researcher Keming Zhang, now at UC San Diego, explains that while Earth may only remain habitable for another billion years due to the sun's increasing heat, this discovery shows that planets can potentially survive their star's red giant phase.. . ) ..
Earth might survive by migrating to a more distant orbit, but would be rendered uninhabitable long before then.. Jessica Lu, associate professor of astronomy at UC Berkeley, emphasises the significance of finding a planet that survived its star's red giant phase, even if it's no longer in the habitable zone...
