My answer is that the Moon is indeed the logical next step for humans, not Mars. If we ever have millions in space in the near future, I expect it will be on the Moon. And meanwhile, the surface area larger than Africa and full of surprises, then I think we are going to be exploring it for a long time with robots and humans, finding new things all the time. It’s not at all the boring place it seemed to some after Apollo. They didn’t have enough time there, or enough experts, to discover the amazing things that are there to be found. They didn’t even find the lunar caves, some thought to be over 100 km long, or the ice at the poles, which we are pretty sure is there, at least some, but hidden from sight in the darkness, not seen light for billions of years.. Anyway - this is a question with many assumptions about why we go into space - Elon Musk wants to colonize Mars as a backup to save humanity. But Earth is by far the most habitable planet in our solar system and will be for the f

NOCTILUCENT CLOUDS STILL GOING STRONG

NOCTILUCENT CLOUDS STILL GOING STRONG:  Usually, August 1st is the beginning of the end for noctilucent clouds (NLCs) in the northern hemisphere. Weather conditions at the top of Earth's atmosphere shift in August, making it more difficult for  meteor-seeded ice crystals  to form. Soon thereafter, NLCs fade from view. As August begins in 2018, however, noctilucent clouds are still going strong. Yesterday, Vesa Vauhkonen photographed a bright display over Rautalampi, Finland: "On the morning of August 1st, some very beautiful noctilucent clouds appeared over Lake Konnevesi--the best I've seen in many years," says Vauhkonen. A similar display appeared over the Talkeetna Mountains of Alaska. "They were the best noctilucent clouds I've ever seen,  extremely bright ," reports eyewitness Tempy Larew. What's happening?  Previous studies  have shown that NLCs sometimes intensify during solar minimum. The idea is that extreme UV rays from the sun dim dur

ESA / David Sing When a planet transits in front of its parent star, some of the light is not only blocked, but if an atmosphere is present, filters through it, creating absorption or emission lines that a sophisticated-enough observatory could detect. Perhaps the most revolutionary find of the past generation, when we think about the Universe beyond Earth, is the discovery that our Solar System isn't the only one out there. 30 years ago, we had yet to find a single planet beyond our own Solar System; today, we're aware of thousands. The rapid developments in exoplanetology have taught us that there are more planets than stars in the Universe, and that Earth-sized, potentially habitable worlds are common. In fact, there are likely hundreds of billions of such worlds in our galaxy alone. But the majority of these worlds are around red dwarf stars: stars where flares and activity are common, and many scientists contend that worlds around these stars should have no
