    I'm gonna miss my buddy Barack :-). In 20 years from now I will read this article again....:

    He is your buddy? I dropped all pathological liars from my own budy list.

    If space is expanding, what is it expanding into? Is it not infinite after all?

    A question beyond our understanding ;-).

    It actually isn t . The cosmology and dictionary are both flawed. Infinity isn t a reality, but a process. BS in English.

    Hold your breath dear forummembers! Yesterday, ESA's ExoMars Trace Gas Orbiter Probe has released its Schiaparelli Lander at 2:42 PM GMT :-)! When everything goes well, the Lander will land on Mars this Thursday, more or less at the same time (October 20th). It is only a lander, and not a rover, and it will mostly serve as a 'test' for ESA's future gigantic ExoMars Rover. But it does have some interesting stuff onboard:

    In red you'll find the landing spot of the Schiaparelli Lander. When everything goes well, it will be measuring the atmosphere of Mars during the dust storm season.....and on Mars too:

    To warm you up a bit, here are fresh new pictures from NASA's Curiosity Rover:

    A small update: It will land on Mars 3:48 PM GMT (which is 4:48 PM GMT+1). It'll get exciting if this attempt from ESA (and Roscosmos) will be successful.

    It seems the Schiaparelli Lander didn't make it :-(. Another failure for ESA.

    So sad about the loss of the Schiaparelli Lander :-(.

    Still, the New Horizons probe keeps sending better and better pictures of the binary Pluto-Charon system. This is the sharpest picture yet of Pluto:

    But to stay a bit happy, this is the descent video of the Mars Curiosity back in 2012. From the moment the heat shield is removed until its incredible landing. It is nothing short of stunning :-). With real sound. What I still find stunning as of today, is how these NASA-people managed to get a package the size of a large pick-up truck on this planet. It's even way more difficult than a small Schiaparelli Lander. Or it should be:

    As a Martian you will be wondering by now who is bombing your planet. But stay away from earth you know our bacillus will kill you dead.

    Have you seen the video @SaintMark?

    That is an example of the colour orange/reddish I actually like these days. ;)

    Have seen the video, as a Martian I would be complaining about littering in my back yard.

    The Juno probe made a new picture of Jupiter's south pole. Though in essence it's actually a 'jupiterrise'. The contrast with the stars makes the picture even more beautiful:

    As a kid I would borrow any astronomy book I could find in the library. Love those pictures.

    Here's a nice video of the Huygens probe descent onto the surface of Saturn's moon Titan:

    An astonishing picture of the binary Charon-Pluto system. This is not a made-up composite. The probe New Horizons photographed this composite exactly this way:

    Finally, a picture in true color of our dwarf planet Ceres :-). Note the beige color:

    Our solar system is truly stunning. Here you'll find the size chart of all 8 planets (Mercury, Venus, Terra -commonly known as Earth-, Mars, Jupiter, Saturn, Uranus, Neptune) and 2 dwarf planets (Ceres, and the binary system Pluto/Charon) in comparison with our start, Sol (also known as: Sun):

    And a comparison with the degree of tilt of every (dwarf) planet:

    And here a simplified size chart, which includes all known dwarf planets in the Kuiper Belt (Haumea, Makemake & Eris, but without Quaoar & Sedna):

    In case you wonder how many objects (dwarf planets) humans have discovered in the Kuiper Belt so far, this chart will give you a good idea:

    Thanks @DarthDimi ;-). This topic brings so much positivity to the forum no ;-)? I am a big big astronomy/astrobiology/space-exploration nerd hehe. And I'm proud of it.

    Pluto has a moon? When did this happen??

    You're kidding no? :P

    Actually, Pluto and Charon cirle around a 'barycenter', a point of gravity that's not located within Pluto. So in a way Charon isn't a moon, and Pluto isn't a moon either. Officially, Pluto and Charon form a 'binary dwarf planet system', the 'Pluto-Charon binary dwarf planet system'.
