Children of a Prosperous Earth - Either Dead or Dormant, depend on how you put it. For me, it's dead. Nobody really gives a thing about the ambitious project. But it's possible that I'll revive (and overhaul) it. Not today though.

NGTS-1 is out! From the first glance it may look quite normal, as a gas giant planet orbiting a rather large red dwarf, but this is the system which contains a planet which tears our planetary formation model apart. How can such a huge planet exist in orbit around such a low-mass star, whose formation debris disk isn't suppose to contain even enough mass for such a planet to form? May science finds out how. This will be a good opportunity for astronomers and enthusiasts alike. As such, we're inviting you to travel to this system to conduct researches on this unique planet to uncover its past, and to test our planetary formation model.
NGTS-1b's size and orbital SMa, relative to its parent star. It's huge.
NGTS-1b is slightly less massive than Jupiter, but is bigger due to all the heat it received from its parent star. Its surface temperature is probably around 790 K, so sulfide and chloride cirrus-like clouds might be able to form on this planet. It is a hot-Jupiter, with orbital period of a few days.
WARNING: DEEP GRAVITY WELL. TORCHSHIP REQUIRED TO TRAVERSE THE PLANETARY SYSTEM.
Tau Ceti is out! A famous star featured in many literature, Tau Ceti has been one of the center of attention from astronomers and sci-fi readers alike. A study in 2012 found signals of five planets orbiting this star, but a revise in 2017 ruled out the three first planets and replaced them with two. The last two planets, e and f, may be habitable.
Note: The mass used is not the planets' minimum mass, but a number I came up after having a fun time figuring out Tau Ceti's possible axis tilt viewed from Earth and stuff. The minimum mass of each planet is as follow:
Tau Ceti g: 1.75 Earths * 5.97219e24 kg = 1.04513325e25 kg Tau Ceti h: 1.83 Earths * 5.97219e24 kg = 1.09291077e25 kg Tau Ceti e: 3.93 Earths * 5.97219e24 kg = 2.34707067e25 kg Tau Ceti f: 3.93 Earths * 5.97219e24 kg = 2.34707067e25 kg

Kepler-90 is out! This is the star system which has nice arrangement of the planets, with smaller planets near the star, and large planets further outward. Yesterday (14 December 2017), scientists announced that they have found another planet (i) in this system, adding the total up to 8, rivaling the Solar System!
