exoplanets with orbits of between 35 and 80 days host a single moon the size of Ganymede.
Computer models reveal that
exoplanets with very saline oceans could have circulation patterns opposite to that on Earth, resulting in dramatic warming of their polar regions, possibly extending their range of habitability.
The planet transits a relatively bright star and exhibits the third largest transit depth of all transiting
exoplanets with V $ < $ 11 in the southern hemisphere, making it a promising candidate for future atmospheric characterization studies.
Finally, we discuss possible compositions for Kepler - 61b with a comparison to theoretical models as well as to known
exoplanets with similar radii and dynamically measured masses.
This planet joins a group of highly inflated transiting
exoplanets with a radius much larger and a mass much less than those of Jupiter.

exoplanets with masses larger than Jupiter's and orbits larger than Pluto's.
In many of these cases, the star will thus take its name from various details of the scientific projects that brought attention to it by discovering its planetary system, which leads to
exoplanets with unwieldy monikers like «2MASS J04414489 +2301513 b» or «MOA -2007-BLG-192Lb.»

exoplanets with stratospheres.
The mission continues to occasionally discover
exoplanets with more limited capabilities in other parts of the sky.

Their findings may also be relevant to investigations of
exoplanets with hazy atmospheres.
Starting with 12 Kepler candidates believed to be small rocky worlds, the BLENDER analysis whittled them down to eight new
exoplanets with radiuses smaller than 2.7 times Earth's, all believed to be in the habitable zone.
Identifying
exoplanets with deep learning: a five planet resonant chain around Kepler - 80 and an eighth planet around Kepler - 90.
«The fact that the first two
exoplanets with measured spectral albedo exhibit significant differences demonstrates the importance of these types of spectral observations and highlights the great diversity among hot Jupiters,» concludes Bell.
«That's going to be really important once we start characterizing
exoplanets with all of these new missions.»

exoplanet with the potential for life, astronomers need to confirm three essential attributes: an atmosphere that contains life - supporting molecules...
To identify a truly Earthlike
exoplanet with the potential for life, astronomers need to confirm three essential attributes: an atmosphere that contains life - supporting molecules such as oxygen and water, plus a size and mass similar to Earth's.

A team of astronomers may have discovered a «hot Jupiter»
exoplanet with an atmosphere that snows titanium oxide — a kind of sunscreen — exclusively on the one side of the planet that is bathed in perpetual darkness.
Scientists have identified a giant
exoplanet with temperatures reaching 7,800 degrees Fahrenheit (4,315 Celsius), the hottest gas giant planet ever identified.
Kepler 421b -
