Sky and Telescope 6 Oct 2021, 18:35 UTC Careful study of data from the New Horizons mission indicates that an iconic, caldera-looking feature isn’t an eruption site.
Universe Today 6 Oct 2021, 15:20 UTC Usually, when the topic of asteroid mining comes up, thoughts turn to the riches of the asteroid belt between Mars and Jupiter. The sheer size and scale of the available resources in these asteroids are astounding and overshadow a much more accessible resource – Near-Earth Asteroids (NEAs) that are much closer to home. Now a team from the University of Arizona (UA) has spent some time looking at these near neighbors and realized some are very similar to one of the most famous asteroids in the belt – Psyche.
Starts With a Bang! 6 Oct 2021, 14:02 UTC If there really is another version of you out there in a parallel universe, what can that teach us about reality?
SPACE.com 6 Oct 2021, 11:09 UTC Over the next few years, companies across the world are planning to launch tens of thousands of satellites into orbit to provide global high-speed internet access. But that access comes at a cost: It will pollute the skies and contaminate astronomical observations.
Universe Today 5 Oct 2021, 23:46 UTC Welcome back to our Fermi Paradox series, where we take a look at possible resolutions to Enrico Fermi’s famous question, “Where Is Everybody?” Today, we examine the possibility that we haven’t heard from any aliens is because no one is transmitting!
Universe Today 5 Oct 2021, 14:31 UTC Carl Sagan once famously, and sarcastically, observed that, since we couldn’t see what was going on on the surface of Venus, there must be dinosaurs living there. Once humans started landing probes on the planet’s surface, any illusion of a lush tropical world was quickly dispelled. Venus was a hellscape of extraordinary temperatures and pressures that would make it utterly inhospitable to anything resembling Earth life.
Centauri Dreams 5 Oct 2021, 10:59 UTC Our doughty Voyager 1 and 2, their operations enabled by radioisotope power systems that convert heat produced by the decay of plutonium-238 into electricity, have been pushing outward through and beyond the Solar System since 1977. Designed for a four and a half year mission, we now have, more or less by accident and good fortune, our first active probes of nearby interstellar space. But not for long. At some point before the end of this decade, both craft will lack the power to keep any of their scientific instruments functioning, and one great chapter in exploration will close.
