NASA telescope discovers a bizarre, half-lava world

Scientists have discovered a world that is almost identical in size to Earth, with a yıldız almost identical to our sun.

But that’s pretty much where the similarities end. The exoplanet, a world outside our solar system, is 10 times younger, exponentially hotter, and likely half-soaked in molten lava seas.

Astronomers found the new planet, HD 63433 d, using NASA‘s TESS probe, short for Transiting Exoplanet Survey Satellite. The mission was designed to discover thousands of exoplanets in orbit around the brightest dwarf stars in space.

The scorched world is the smallest and closest known young exoplanet, at only 73 light-years away. Scientists estimate it’s about 400 million years old, a mere whippersnapper compared to our 4.5 billion-year-old home planet.

“Young terrestrial worlds are critical kontrol beds to constrain prevailing theories of planetary formation and evolution,” the discoverers said in a new paper published in The Astronomical Journal.

Mashable Light Speed

The number of confirmed exoplanets özgü risen to 5,569, with over 10,000 other candidates under review. Statistically speaking, the growing tally only scratches the surface of planets believed to be in space. With hundreds of billions of galaxies, the universe likely teems with many trillions of stars. And if most stars have one or more planets around them — well, that’s an unfathomable number of hidden worlds.

HD 63433 d is intriguing because one of its sides is always facing its yıldız. Furthermore, it is much closer to its yıldız than Earth is to the sun: In fact, it’s eight times closer to its host yıldız than Mercury is to the sun. That makes the exoplanet’s orbit so snug that its year is only four days long. As any experienced sunbather knows, if you don’t turn over, one side is going to get seriously burned.

Astronomers believe the side facing the yıldız is subjected to temperatures of about 2,300 degrees Fahrenheit. But the backside of the planet that never receives starlight is a mystery, something the research team hopes to learn more about in the future. The James Webb Space Telescope, the most powerful infrared telescope in the cosmos, could reveal more details about this young world, as well as search for hints of an atmosphere.

“Young planets are exciting because we can study how planets change over time by measuring their properties at different ages,” said Andrew Vanderburg, one of the co-authors, on X. “This is kind of like studying how humans age by observing a baby, a child, a teenager, and an adult, without waiting for the baby to grow up.”
