Scientists may have found a volcanic world on the brink of destruction where the chances of finding life are highly unlikely. A scientist likened the site to a fictional, lava-strewn Star Wars world.
But instead of an alien planet, the world seems to be a volcanic moon, much like Jupiter's volcano-covered Io satellite orbiting an exoplanet named WASP-49. This planet orbits a star that is 550 light-years from Earth in the constellation Lepus, which travels an orbit every three days of the earth.
A team of scientists from the University of Bern in Switzerland said hot, bubbling lava could continue to flow on the surface of this exome or the moon orbiting a planet outside our solar system. This conclusion is based on the high content of sodium gas detected in the planetary system. The presence of the Moon is suspected by observations of the mother star of WASP-49b and by theoretical models, researchers said.

"It would be a dangerous volcanic world with a molten surface of lava," Apurva Oza, a postdoctoral fellow at the Physics Institute of the University of Bern and co-author of The New Study, said in a Declaration of the University of Bern . "A place where Jedis die, which Anakin Skywalker is dangerously known for." Kenobi and later built a castle as Darth Vader.)
An Extraterrestrial Io from Beyond
The Exomoon is described as an extreme version of Jupiter's moon Io . As the fifth moon of Jupiter, Io is the solar system's most volcanically active body with hundreds of volcanoes on its surface.
By comparing the observations of Io with those of the potential exomoon, as well as calculations of the mass loss and sodium content of the exo moon in the planetary system, the team believes they have found the first exo Io (an Io Beyond the Solar System.)
"The sodium is exactly where it should be," Oza said, "The neutral sodium gas is so far away from the planet that it's probably not just being expelled from a planetary wind."
Another key factor is that released by the planetary system Tidal forces that keep the Moon's orbit stable keep it warm and potentially volcanically active, but the research team needs more evidence to prove that the Exomoon is actually volcanically active and they want to gain more data through ground-based and space-based observations of the planetary system. 1
