Astronomers have made the first direct observation of an exoplanet using a technique known as optical interferometry.
According to a press release from the European Southern Observatory or ESO, the exoplanet HR8799e was discovered in 2010, 129 light years from Earth in the Pegasus constellation.
It is one of three planets orbiting around the star HR8799. CNN reports that the exoplanet lies closest to its host star, and takes 40 to 50 years to make a full orbit.
Using the GRAVITY instrument on ESO's Very Large Telescope Interferometer, ESO scientists found that HR8799e is a 'super-Jupiter.' It is much more massive than any planet in our solar system, but also younger.
Due to leftover energy from its formation and a powerful greenhouse effect, the temperature on HR8799e is an inhospitable 1000 degrees Celsius or about 1,616 Fahrenheit.
According to ESO, analysis showed that the exoplanet's atmosphere has more carbon monoxide than methane.
Clouds of iron and silicate dust were also found, which when combined with the excess carbon monoxide, suggests a huge, violent storm in HR8799e's atmosphere.
CNN reports that researchers are planning long-term follow up observations of HR8799e, and can study it more to learn more about the formation of planets and planetary systems.
