• team of astronomers has uncovered an Earth-like planet orbiting a star located 4,000 light years away from the solar system, potentially offering insights into Earth’s distant future. The rocky planet, about the same mass as Earth, revolves around a white dwarf in the constellation Sagittarius.
  The discovery brings a glimmer of hope for Earth’s survival when our sun enters its final stages. It suggests that Earth could potentially avoid being consumed by the expanding sun, opening up possibilities for human migration to the outer solar system, with moons such as Europa, Callisto, and Ganymede around Jupiter, or Enceladus near Saturn, becoming possible havens for future generations.

Future of Earth

“We do not currently have a consensus whether Earth could avoid being engulfed by the red giant sun in six billion years,” said Keming Zhang, the lead author and a former doctoral student at the UC Berkeley, who is now an Eric and Wendy Schmidt AI in Science Postdoctoral fellow at UC San Diego.

“In any case, planet Earth will only be habitable for another billion years, at which point Earth’s oceans would be vaporized by the runaway greenhouse effect-long before the risk of getting swallowed by the red giant

What is a white dwarf

A white dwarf is a stellar remnant composed mostly of electron-degenerate matter. It is extremely dense: its mass is comparable to the Sun’s, while its volume is comparable to Earth’s. White dwarfs are thought to be the final evolutionary state of stars whose mass is not high enough to become a neutron star or black hole. This includes over 97% of the stars in the Milky Way.
White dwarfs are very hot when they form, but because they have no source of energy, they will gradually cool over billions of years. Eventually, they will become black dwarfs, which are cold and dark stellar remnants.
White dwarfs are fascinating objects that teach us about the life cycles of stars and the nature of matter under extreme conditions. They are also important for understanding the evolution of galaxies and the universe as a whole.

• Recent discoveries have revealed several Earth-like planets:
  KMT-2020-BLG-0414Lb: This Earth-sized planet orbits a white dwarf star, offering insights into Earth’s potential future as our Sun ages.
  Gliese 1214 b: While significantly larger than Earth, this planet orbits within its star’s habitable zone, raising the possibility of liquid water and potentially life.
  Kepler-452b: Dubbed “Earth 2.0,” this planet is slightly larger and older than Earth, orbiting a star similar to our Sun.
  These discoveries offer hope for finding habitable worlds beyond our solar system and deepen our understanding of planetary formation and evolution.

Yes, there has been a recent discovery of an Earth-like planet orbiting a white dwarf star in the constellation Sagittarius. This planet, designated KMT-2020-BLG-0414Lb, is about the same mass as Earth and orbits its star at a distance roughly twice that of Earth’s orbit around the Sun.
This discovery is significant because it offers a glimpse into the potential future of our own planet as our Sun ages and becomes a white dwarf. It also raises the possibility of life existing on such a planet, although further research is needed to confirm this.
The discovery was made by a team of astronomers using the Keck Telescope in Hawaii.

Could humanity find refuge beyond Earth? As the sun swells into a red giant, the habitable zone in the solar system will shift outward to the orbits of Jupiter and Saturn. Many of their moons, such as Europa and Callisto, could become ocean worlds capable of supporting life. Zhang suggested, “Humanity could migrate out there.”
