Astronomers believe they have discovered the first known moon beyond our solar system, in the orbit a huge planet around 8,000 light years away.The so-called exomoon, which is estimated to be the size of Neptune, will also be the most known moon, far more than anything known to exist in our own solar system. The team behind the apparent discovery said it needed further confirmation but they did not find any other convincing explanation for their data.The first exomoon is obviously an extraordinary claim and it requires extraordinary evidence,” said David Kipping, a astronomer at Columbia University in New York, who spent more than a decade hunting for far flung moons.Sign up for Lab Notes – The Guardian’s weekly science update
He said that the moon’s estimated size was on a scale that was “hardly expected” and “defies easy explanation” based on the current theories of moon formation.
Kipping and his colleague Alex Teachey discovered the Keiler space telescope using the discovery of approximately 300 distant planets after analysing data. The planets are revealed by a momentary dimming of starlight as they are in front of their host star, in which astronomers call a transit.Kipping and Teachey noticed strange anomalies in the transit data of a gas planet, Kepler 1625b, which is often the size of the Jupiter.
“We saw little deviations and wobbles in the light curve that caught our attention,” Kipping said. Artist’s impression of the exoplanet Kepler-1625b with its suspicious moon.

The findings were intriguing enough to win over 40 hours of observation time on the Hubble space telescope, which is four times more powerful, to investigate further.
Using Hubble, they saw a second, very small dip in the star’s brightness 3.5 hours after the planet’s transit, hinting at “a moon the planet like a dog follows its leash”. On another transit, the planet appeared 1.25 hours ago than predicted. This is consistent with the planet and moon of a common center of gravity, because of the planet its predicte philosophers from wobble believe that they have discovered the first moon outside our solar system, about 8,000 light years In the center of a big planet.The so-called exomoon, which is estimated to have a size of Nepone, will also be the largest moon moon, which is in our own solar system. After clear discovery, the team said it needed further verification but he failed to find any reliable explanation about his data.
“The first promone is clearly an extraordinary claim and needs unusual evidence,” said a star Carwood David Capping at Columbia University in New York.He said that the size of the moon was on the scale that “had probably had progress” and “used to make an easy explanation based on the current ideology of moon formation.”After analyzing data from over 300 distances, using Captain Space Telescope, Cunningham and his colleague Alex Xiese discovered this. The planet is revealed by a star light as a moment length because they pass in front of their host stars, which have a transit of the stars.Cating and taxi felt amazing Buddhist figures in the gas planet, Captain 1625b’s transit data, which is often the size of the joint.

The results were very interested in winning the 40-hour observation over the hubble space telescope, which is four times more powerful, to further investigate.
Using the hubble, they saw a little dip in the brightness of the planet after 3.5 hours, “pointing to the planet like a planet like a planet on a dog like a dog.” On another transit, the planet predicted 1.25 hours ago. With planet and moon it is a common gravity center, which is because the planet had to go through its predecessor.
Planetary Planet ‘Joining the Gabon‘Moon is only 1.5 percent of its planet’s planet, which is near the proportion of mass ratio between the earth and its moon. Our moon is supposed to be established through an early collision with a large body, which blew the material after which a later ball was found. However, Kepler is 1625b and its moon gas, are not monsters, raise questions on how to
