Here’s an interesting new Kepler planet: Kepler-1655b, a gaseous Mini-Neptune that is one of very few planets its size to have a mass measurement. It is 2.2 times the radius of Earth and 5 times the mass, and gets about 147 times more sunlight than Earth. Because the planet orbits so close to the region where atmospheric loss will take hold, it is an interesting target for further study.

The potentially habitable planet K2-18b now has a confirmed mass and composition! This planet is 2.28 Re, 8.0 Me, and has a density of 3.7 g/cm3, which indicates a water-rich composition. In addition, a second non-transiting planet - K2-18c - was found with the HARPS spectrograph, with 7.5 times the mass of Earth and a year lasting 9 days.

I will LHS 1140b alone; I have no problems with that planet. In general, though, red dwarfs are highly active. There's nothing like UV Radiation and sunburns on Ross 128b and Proxima Cen. b. Before observatories start dedicating their exoplanet searches to red dwarfs, they should make sure that the red dwarfs they look at are not active.

Yeah, lets hope this thing isn't a mini-Neptune. 3.7 g/cm^3 is a little thin for a super earth. The water-rich composition is likely a thick atmosphere. Sorry.
You can guess the first thing I'm going to do: look at light curves to try to find variability in the parent star. Unfortunately, I can't find anything on this star from the AAVSO, so I'll either come back in an hour or to and crash the party, or I'll wait till the next clear night and start taking pictures. Either way, looking for Earth-like planets around M stars is a bad idea.

When you thought there couldn't be any exoplanet atmospheres worse than the Mega-Meatgrinder of HD 189733 b or Kepler-13b's sunscreen rain or WASP-121b's glowing water stratosphere:

Correction: MapArray does NOT work. At all.
Why? Well, at this point I wouldn't be surprised if it's because the bloody fairy godmother says no - it should work fine!
sigh computers... sorting this out is gonna take a while.

There is no task more tedious than cataloging EVERY SINGLE PLANET found by me, shutcheon, Vidar87, Libmar96, @Cabbink, and others. I'm not even halfway done and so far I've cataloged 72 planets in 32 systems, with 9 in the habitable zones of their stars.

IMPORTANT MESSAGE ABOUT THE FUTURE OF MY MODS
Hey again, Kerbals. I have a confession to make.
I've reached the point where I have just too many planets to work on, where I keep darting from planet pack to planet pack because they all deserve updates, but end up getting nowhere at all. Therefore, after a lot of thinking, I've decided to do two things:
1. I will be making a schedule for what planet pack to fix in what order. Of course, planets may move up or down on this list depending on the severity of potential bugs.
This schedule is as follows:
Spoiler1. Planet Cerillion
2. Evolution
3. Stock Planet Expansion
4. C# mods (INSTANTIATOR & PQSMod packs)
5. Arkas
6. Planet Cyran
As you can see, some packs are missing. This is because:
2. I will discontinue some of my mods.
First mod to get the axe is Total Rebuild (...and Cyran may follow in the future). I'm terribly sorry for discontinuing some of my mods, but right now there is just too much to work on.

I almost forgot that it's now been two whole full years since I joined the KSP forums. Things sure have changed since I first became a member here. I'd say these forums are, by far, one of the BEST online communities online. Period.

It looks like astronomers discovered another "habitable" planet. Unfortunately, Ross 128 is a UV Ceti type star (AAVSO VSX Classification)!!!!
Ross 128b has a short orbital period and is almost certainly tidally locked, making it nearly impossible to generate a strong magnetic field. Since Ross 128b has frequent, violent flares, by-by atmosphere!

Yes, I look primarily for novae and irregular variables, and I have found my share of UV Ceti stars (GSC 03123-00626 was the first one).
Ross 128 is actually a pretty old star, about 9.5 billion years old. You're assuming that this star will have as much iron as newer stars like LHS 1140.
Yes, iron does help to generate magnetic fields. Suppose that the iron composition is 3 times higher than Earth's. That only means that the magnetic field is minimally enhanced by at most one order of magnitude. However, these planets spin about 10 times slower than earth does, canceling out the iron. Considering the CME's generated by this star (which still dwarf any kind of activity our sun produces; when was the last time the sun doubled its brightness as a result of a CME), and the extreme proximity of this planet to its star, even an Earth-strength magnetic field would not have protected this object's atmosphere for the 9.5 billion year age of the system. Unfortunately, @StarCrusher96 would have to make a boring version of Tylo in order to accurately depict this planet in his mod.
It's time to move onto other planets.

you're kidding
Check the light-curves. There must be really nothing like deadly ultraviolet radiation.
any planet will be tidally locked with its parent star if the orbital period is 10 days, meaning little or absolutely no magnetic field. A few "huge flares" on the timescale of the universe will surely have stripped off the atmosphere. Dude, UV Ceti stars are not hard to catch; I find new ones all the time. The most recent studies are only saying "rather quiet" because the star only fluctuates by a magnitude when it flares up, which is only a comparison to the usual 2.5 magnitudes of most UV Ceti stars. Still, the system is as bad for life as TRAPPIST One. And, when Virgo swings around in a few months, I'll be sure to take more measurements; it will stop @StarCrusher96 from making yet another red-dwarf system in KSS.
In general, any type of UV-Ceti star is really bad for life.
