![]() ![]() The second generation of stars may have already had rocky planets orbiting them, but our ability to directly image exoplanets is constrained to giant exoplanets at great distances from bright stars. accomplished through the work of Jason Wang and Christian Marois. With the right equipment, such as NASA’s upcoming James Webb Space Telescope, we should be able to probe the atmospheres of many different planets for compounds like water, methane, ammonia, carbon dioxide, and many signatures, or at least hints, of life and complex chemistry.ĭirect imaging of four planets orbiting the star HR 8799, 129 light-years away from Earth, a feat. And finally, the third can only be leveraged at present for a small fraction of transiting exoplanets, but is known as transit spectroscopy. The second is known as the transit method - leveraged most famously by NASA’s Kepler mission - and gives us the physical radius and orbital period of the exoplanet. The first example is known as the radial velocity method in exoplanet sciences, and it allows us to determine the mass and orbital period of the exoplanet that tugs on the star. and, if the planet that intervenes between the star and our line-of-sight has an atmosphere, then a tiny portion of that starlight will filter through that planet’s atmosphere.when a planet passes between its parent star and our line-of-sight, it obscures a portion of the star’s disk, enabling us to notice a periodic dip in the star’s brightness,.when a star gravitationally pulls on an orbiting planet, the planet pulls back on the star, causing the star to move in response to the planet’s presence,.There are ways to probe the properties of a planet without direct imaging, and we’ve already been successful at leveraging some of them. Meanwhile, the icecaps advance and retreat dependent on our axial tilt’s orientation, providing yet another annual variation in our surface’s properties. The clouds change on a much faster timescale, sometimes covering the continents, sometimes the oceans, and sometimes a bit of both. As the seasons change, the continents change color between green and browns and white, depending on the success of vegetation and/or the cover of ice and snow. ![]() Our planet contains continents, oceans, and partial cloud cover, as well as polar icecaps. ESA / CHEOPS collaborationĪs seen from up close, the signs of not only life, but our intelligent, technologically advanced human civilization are unmistakable. ![]() This is a difficult, but not impossible, task for modern technology. observe an Earth-sized planet at an Earth-like distance from a Sun-like star, we would need to block out the Sun-like star's light to about 1 part in 10-to-100 billion. Yourmom1 on The “P.S.This artist's impression of the Nu2 Lupi planetary system shows three exoplanets.There’s also a thread on reddit about it over here. You can follow the issue on Twitter over here. In my humble opinion, the patch should have been out about an hour or two after release. 144 hz machines are standard for a lot of gamers, including myself (I was just zipping around the net and noted two people looking forward to playing Civ: BE at 144 hz, before the launch tonight), and now we can’t run the game in the standard computing resolution almost everyone uses - without running it in Windowed mode. I love the Civ games but this is really beyond the pale in terms of a pathetic glitch that got through. You got it, that’s the issue (144 hz), according to this link: Apparently, during all their testing over at 2k and Firaxis and whatever, no one ever bothered to try to run the game at that resolution on a 144 hz monitor. Well, I was waiting with bated breath for the new Civilization: Beyond Earth I downloaded it at midnight, and I can’t play it (except in Windowed mode, which is distracting as all hell and which I will not do on principle) in the standard 1920 by 1080 pixel resolution (“1080p”, but us computer geeks know it better as the simple 1920×1080 standard resolution).
