    That kind of sucks about the stellar wind pressure. The star probably striped the planet of whatever atmosphere it could have had. Also, has there been any more data to back up the theory of a second planet?

    Not that I have insider knowledge of, but I couldn't say for sure. I don't diligently read every pre-print email that goes out.

Its magnetopause standoff distance consequently undergoes sudden and periodic changes by a factor of 2 to 5. Proxima b will traverse the interplanetary current sheet twice each orbit, and likely crosses into regions of subsonic wind quite frequently.
    if i'm understanding bolded right, that means the stellar wind increases in pressure throughout the day, and the effective protection of the magnetic field shrinks by a factor of 2 to 5 during the higher pressure periods? Also, the sentence after that doesn't make sense to me. what is the interplanetary current sheet? subsonic winds????

    Crazy thing is that photo was taken 1.6km from the surface (it was reported as 16km but it's most likely an error).

    Notice the lines in the cliff area? That looks like water created that. I bet this comet used to be part of a planet.

    More exoplanets found 39 Light Years away.

    7 Planets around an ultra cool dwarf star about the size of Jupiter. Out of the 7 planets, 4 are are in the habitable zone. The orbits are less than 12 days so it made it easy to confirm several transits.

    I'm not sure why NASA felt the need to make an announcement of that. Our exoplanet catalog now is friggin' huge and habitable zone means literally nothing. Can be smack dab in the middle of the habitable zone but have no atmosphere or etc or storms so strong they'd rip humans limb from limb (looking at you most recent research into proxcenB).

    New mandate on their shift to space exploration? Press conference all the things?

    I mean, to be perfectly honest, it's great science. It's very interesting, it has a lot of potential for breakthroughs in extrasolar planetary system dynamics.

    It's just that the media release is dumb as fuck and filled with baseless hypotheticals, maybes, and assumptions that aren't grounded in any of the science that we actually observed.

    It triggers me.

    So Sath does this mean we are gonna settle all of these planets immediately? That's what my FB feed is telling me.

    No need, they've already been settled for us and the inhabitants have already started texting Trump to arrange visits.

    You can't think of any possible reason NASA might want to demonstrate value in public in a way that's appealing even to the scientifically illiterate right now? Nothing at all?

    I never said I didn't understand why they are doing it, I just said it annoys and aggravates me.

    Also, as the trend continues, there will inevitably be a backlash of buyers remorse. You can't build up the hopes and dreams of the scientifically illiterate forever and expect them to not turn on you when your "amazing discoveries" cannot be appreciated by laymen.
