A New Type of Exoplanet Has a Magma Ocean That's Lasted 5 Billion Years
A study led by the University of Oxford has identified a new type of planet beyond our Solar System – one that stores large amounts of sulphur deep within a permanent ocean of magma. The magma ocean has lasted 5 billion years so far, while Earth's magma ocean likely lasted only tens of millions of years.
The observations of a distant star pose a mystery to science: A celestial body discovered there is far too easy for its size, which contradicts previous explanations. Simulations now show that it must consist of liquid rock.
Fiery, stinky ‘lava’ planet discovered by scientists — temperature can hit a hellish 2,700°F
Scientists have uncovered a hellish “lava world” where temperatures soar to a blistering 2,700 degrees Fahrenheit — hot enough to melt rock into a churning ocean of magma and fill the air with the stench of rotten eggs. The distant exoplanet, known as L 98–59 d, isn’t just scorching — it’s…
An international team of scientists, led by the University of Oxford, has identified a new kind of planet outside the solar system that does not fit into any of the categories known so far.This celestial body is characterized by harboring enormous amounts of sulfur in the depths of a permanent ocean of magma.The planet, called 'L 98-59 d', orbits a star located about 35 light years from Earth, presents a surprisingly low density and an atmospher…
35 light-years away from Earth, scientists find a liquid planet
Five billion years after its birth, a planet is not rich in sulphides. But L98-59d remains so, puzzling astronomers. A closer look revealed something that scientists were surprised to find out. The planet is made up of molten magna stretching for thousands of kilometers below its surface. Astronomers at the University of Oxford have identified a liquid planet made up of molten lava. About 35 light-years away from Earth, this planet, L98-59d, orb…
The universe continues to surprise scientists with the discovery of celestial worlds that challenge our understanding of planetary formation and evolution. New research in Nature Astronomy reveals that the exoplanet L 98-59 d, located approximately 35 light-years from Earth, represents a novel class of rocky bodies. This unusual world possesses a vast magma ocean that, unlike its counterparts, has remained in a liquid state for an impressive fiv…
