Geekwire 18 Feb 2018, 02:39 UTC Mining asteroids for water and other resources could someday become a trillion-dollar business, but not without astronomers to point the way. At least that’s the view of Martin Elvis, a researcher at the Harvard-Smithsonian Center for Astrophysics, who’s been taking a close look at the science behind asteroid mining.
Starts With a Bang! 17 Feb 2018, 15:01 UTC If you take a look out at the Universe, and in every direction you look, you see objects rushing away from you, what would you conclude? Would it be that you’re a repellant, somehow? That the fabric of space itself is expanding? That you’re at the center of an earlier explosion, and everything else is just speeding away from the explosion point? These, as well as other options, might all seem reasonable, but somehow, scientists always say “the Universe is expanding” as though no other alternative would do. Why is that? Our reader Buck wants to know, asking: How do we know space is expanding? In relation to what? Red shifting galaxies growing farther apart could be doing so in infinite space as opposed to expanding space. Believe it or not, the answer is written on the face of the Universe itself.
Scientific American 16 Feb 2018, 19:00 UTC When ‘Oumuamua, a mysterious interstellar object, swept through our solar system last October, it elicited breathless news stories all asking the obvious question—is it a spaceship? There were no signs it was—although many people seemed to hope otherwise.
OrbitalHub 16 Feb 2018, 13:00 UTC ESA’s XMM-Newton has spotted surprising changes in the powerful streams of gas from two massive stars, suggesting that colliding stellar winds don’t behave as expected. Massive stars – several times larger than our Sun – lead turbulent lives, burning their nuclear fuel rapidly and pouring large amounts of material into their surroundings throughout their short but sparkling lives.
SPACE.com 16 Feb 2018, 11:59 UTC When NASA's Voyager 2 spacecraft flew by Neptune in 1989, it observed large, dark storms flying through the distant planet's atmosphere. Since then, scientists have monitored Neptune using the Hubble Space Telescope and seen new storms develop.
ESO Blog 16 Feb 2018, 11:00 UTC Part of ESO Headquarters in Garching, Germany, is currently in a frenzy of activity as we prepare to open the ESO Supernova Planetarium & Visitor Centre in April 2018. This cutting-edge free astronomy centre is equipped with a 14-metre planetarium dome and an amazing exhibition that takes visitors on a journey to the stars. It’s a lot of work to install a planetarium system from scratch, but to engineer Max Rößner, the ESO Supernova is like a giant playground.
