They don’t call Hafþór Júlíus Björnsson ‘The Mountain’ for nothing.

In 2015, the strong man and Game of Thrones actor broke a millennium-old record by taking – or more accurately, staggering – five steps with a 650 kilogram (1,430 pound) log on his back.

To most of us, this was simply an extraordinary example of heroic strength. To scientists, this feat marked a crushing limit to the gravitational pull any mortal could ever hope to endure, setting a boundary on the mass of planets we might expect to colonise.

In 2015, the asteroid missed Earth by just 300,000 miles and was visible to those with good telescopes. This year, the closest it will come is 25 million miles — which is way too far to tell what it looks like.

The Milky Way has a violent past. When it isn’t swallowing renegade sausage galaxies, it seems to be waging endless games of interstellar tug-of-war with its nearest galactic neighbors — and not always winning. According to a new study published Sept. 19 in the journal Nature, one such encounter ended with a cosmic wound to the Milky Way’s disk that still hasn’t fully healed, 300 million years later.

That wound, researchers say, is visible in a cluster of several million stars that are not behaving as they should be. While still rotating around the Milky Way’s galactic center, these rogue stars also orbit around one another in a wobbly, spiral pattern that has only become more tangled over the past eon.

“We have observed shapes. [of star clusters] with different morphologies, such as a spiral similar to a snail’s shell,” lead study author Teresa Antoja, a researcher at the Institute of Cosmos Sciences (ICCUB) at the University of Barcelona, said in a statement. “These substructures allow us to conclude that the disk of our galaxy suffered an important gravitational disturbance.”

Iridium, the satellite communications network, announced Thursday that it intends to work with Amazon Web Services to connect the leading cloud-provider’s internet-of-things services with Iridium’s satellite network in 2019.

This new service will be called CloudConnect. It builds on an existing IoT satellite network operated by Iridium to allow companies using AWS IoT services to reach places where the physical internet does not reach, which even in 2018 is a lot more places than you might imagine. Iridium is joining the AWS Partner Network along with this announcement, which will present Iridium’s satellite network as a deployment choice for AWS customers using its IoT services.

The Arch Mission Foundation today announced the creation of an archive of knowledge encoded into synthetic DNA by Microsoft, Twist Bioscience Corporation, and the University of Washington to be included in the Lunar Library™. The DNA Archive will feature 10,000 crowdsourced images and the full text of 20 important books, among other items. The data is encoded into billions of synthetic DNA molecules and encapsulated for long-term preservation. Collectively this data will represent the first Special Collection of the Lunar Library, which the Arch Mission Foundation announced last spring.

The Arch Mission Foundation sought partners that could help curate these materials and assist in achieving a remarkable collection that reflects both the best of human knowledge, as well as the most ambitious technical abilities in the emerging new field of molecular data storage. Molecular data storage is a new technology for storing and retrieving data from molecules of synthetic, non-living DNA.

DART is a test of the kinetic impactor technique, a potential method to deflect an asteroid on course to impact the Earth. Kinetic impactors are one of only a small number of approaches we think are mature enough to deploy in the near future if they are needed (though we hope they won’t be). The most powerful asteroid-deflection technique is the use of a nuclear device. While such a device makes for good (and bad) sci-fi movies, there is widespread desire to develop alternate techniques.

The kinetic impactor concept is rather straightforward: ram the threatening object with a spacecraft and change its orbit so that it misses our planet. In theory, we could heave ever-larger masses at ever-faster speeds to deflect ever-larger objects. However, we think there is a practical limit — we don’t want to break up an incoming object into several pieces, lest we replace one big impact with multiple, only-slightly-smaller impacts. Exactly where that tradeoff lies is still uncertain, but we believe we can keep an object intact if we change its speed by less than the object’s own escape speed. In other words, since we think a lot of these objects are loose aggregates of gravel held together by gravity, we don’t want to shove so hard that we accidentally overcome that weak gravity and disperse the gravel.

Astronomers found something not predicted by current theory when they took a closer look at the emissions from a neutron star with a very strong magnetic field.

The thought of colonizing Mars has science fiction aficionados, scientists, and billionaire entrepreneurs staring up at the night sky with renewed wonder and inspiration. But the key to achieving the lofty goal of colonizing and building extensively on a new planet may not exist out among the stars, but under our feet right here on Earth.

Christopher Maurer, an architect and Founder of Cleveland-based Redhouse Studio, and Lynn Rothschild, a NASA Ames researcher, believe algae and mycelium (the vegetative part of a fungus that consists of a network of fine white filaments) may make the perfect building material on Mars.
