In their paper, the co-authors argue that gravitational tidal heating caused by the gravitational friction of an earth-like exo-moon on an eccentric orbit around a Jupiter-like planet lying at a Jupiter-like distance from its parent star, could, in fact, create habitable conditions.

Scientists observing a distant galaxy catch a black hole in the middle of destroying a planet larger than Jupiter.

Located 168 light years from Earth orbiting the star Kappa Andromedae, this planet is about 12.8 times more massive than Jupiter, the largest planet in our solar system.
FORBES: Astronomers Locate Massive 'Super-Jupiter' Around Giant Star
At about the same time, a team of professional astronomers was pulling off a similar trick for a planet the size of Jupiter in orbit around a star 32m times farther from Earth than the sun.
ECONOMIST: Astronomers may have found their first Saturn lookalike
Lying only 10 light years away in the equatorial constellation of Eridanus, it was already known to harbor at least one extra-solar Jupiter-like planet, which orbits the star roughly every 7 years.
Before that it was in an orbit that went from the orbit of Jupiter out past the planet Uranus.
On Monday, January 21st, the Moon will appear amazingly close in the sky to the largest planet in our solar system, Jupiter.

The largest planet in the solar system, Jupiter, has these cloud of Trojan asteroids that straddle its orbit, so that would seem to violate a plain reading of the definition.
It's not even a pluton but a real honest to goodness planet-planet, sitting right between Mars and Jupiter.
This, in turn, means that the thing cannot be all that much bigger than Jupiter, the largest known planet.
Their simulations included the effects of eclipses and tidal heating on climate for an earth-twin in orbit around a Jupiter-like gaseous giant planet.

About one-fifth of them are home to a gas giant like Jupiter or a still more massive planet.
Yet scientists are already speculating that this planet may be of a similar size to Jupiter and have its own ring system.
In a flash of intuition, he had it: the new stars near Jupiter were actually moons, orbiting the planet as our moon orbits us.
On the plus side, the ability to directly detect light from a planet closer to the size of Earth than a Jupiter-sized gas giant is a positive step forward in our ability to learn more about planets that might be habitable.
The Sun enters Scorpio and aspects every slower planet except Pluto, and there's an intense Mars-Jupiter opposition.

Using these two instruments, the scientists were able to examine the event and determine that the mass of the planet being devoured by the black hole was somewhere between 14-30 times that of Jupiter.

This sweep around the home planet will then give the mission a gravitational boost and the velocity required to get it out to Jupiter in July 2016.
