An anonymous reader shares a report: In a paper [PDF] published on the online research archive arXiv, Columbia astronomy students Zephyr Penoyre and Emily Sandford proposed the idea of a "lunar space elevator," which is exactly what it sounds like -- a very long elevator connecting the moon and our planet. The concept of a moon elevator isn't new. In the 1970s, similar ideas were floated in science fiction (Arthur C. Clarke's The Fountains of Paradise, for example) and by academics like Jerome Pearson and Yuri Artsutanov. But the Columbia study differs from previous proposal in an important way: instead of building the elevator from the Earth's surface (which is impossible with today's technology), it would be anchored on the moon and stretch some 200,000 miles toward Earth until hitting the geostationary orbit height (about 22,236 miles above sea level), at which objects move around Earth in lockstep with the planet's own rotation. Dangling the space elevator at this height would eliminate the need to place a large counterweight near Earth's orbit to balance out the planet's massive gravitational pull if the elevator were to be built from ground up. This method would also prevent any relative motion between Earth's surface and space below the geostationary orbit area from bending or twisting the elevator. These won't be problems for the moon because the lunar gravitational pull is significantly smaller and the moon's orbit is tidally locked, meaning that the moon keeps the same face turned toward Earth during its orbit, therefore no relative motion of the anchor point.

Smashing of monster asteroid half a billion years ago thought to have caused mini ice age

An enormous dust cloud that swept through the ancient solar system sent Earth into a mini ice age that sparked an explosion in primitive life on the planet, scientists say.

The space dust was created when a monster asteroid was smashed to pieces in a violent collision somewhere between Mars and Jupiter nearly half a billion years ago.

Astronomers have almost certainly detected a second interstellar comet zooming through our Solar System, but there's still quite a lot of work to be done to find out more about this alien space rock. In the weeks and months to come, astronomers will continue to observe this visitor with as many ground and space-based telescopes as possible to determine if it is, indeed, interstellar and figure out where it came from. From a report: An amateur astronomer, Gennady Borisov, first spotted this object on August 30th with his own telescope in Crimea. At the time, it wasn't immediately clear that the object -- named C/2019 Q4 -- wasn't from around here. As time has passed and more people looked at this thing, they've realized that the path that C/2019 Q4 is on does not loop around the Sun. Additionally, it's going super fast: about 93,000 miles per hour (150,000 kilometers per hour), which is faster than any object from the outer fringes of our neighborhood would be traveling. As NASA and an international team of experts announced last week, the signs all point to it passing through our Solar System on its way from some distant origin. The astronomy community hasn't officially confirmed that C/2019 Q4 is interstellar yet, though everyone is nearly certain about its status. "After getting enough data, I suspect we'll be assigning a permanent designation to say this object is interstellar," Davide Farnocchia, who is studying the comet at NASA's Center for Near-Earth Object Studies at JPL, tells The Verge. "But basically, there's no doubt from the trajectory that it is interstellar." The good news is that if this comet is truly from outside our Solar System, we caught it at a great time -- when it was moving on its way in toward us, rather than on its way out. That means astronomers will have more than a year to continue observing this thing, allowing them to potentially refine its trajectory or even tell us what this mysterious rock is made of.

Happy 43rd birthday to Space Shuttle Enterprise

Roundup Unlike SpaceX's Crew Dragon, which plops down in the ocean at the end of a mission (ideally in one piece), Boeing's CST-100 Starliner is designed to land on, er, land. As NASA and Boeing inch ever closer to its first crewed launch, rehearsals were conducted last week to practice locating a capsule, safing it and preparing for hatch opening.…
