How do stars form?
We know they form from massive structures called molecular clouds, which themselves form from the Interstellar Medium (ISM). But how and why do certain types of stars form? Why, in some situations, does a star like our Sun form, versus a red dwarf or a blue giant?
Since the dawn of time, humankind has looked to the skies and sought to conquer them. For thousands of years we tried and failed until, at last, we could soar amongst the birds. We built biplanes that danced upon gusts of wind, strapped sails to our back and leapt off fog-drenched mountaintops, launched warplanes into the wild blue yonder to rain terror from above. The heavens were soon streaked with the vapor trails of jumbo jets; the oligarchy used its deep pockets for casual jaunts to the threshold of outer space. And then, with the skies at last firmly in our dominion, we once again turned our eyes upward and declared, “Know what would look great up there? Pizza.”
The technology to flood our skies with millions of pizza boxes does not exist just yet, but it’s taken a huge leap forward in Israel, where, The Wall Street Journal reports, Pizza Hut is launching the world’s first ever full-time drone delivery service. The pilot program is being heavily regulated by the government, and Pizza Hut’s human delivery drivers don’t need to worry about being replaced (yet), as the drones will not be making direct-to-customer drop-offs. Instead, the flying robots will bring multiple orders to designated landing zones outside of Pizza Hut’s normal delivery radius, where they’ll be picked up by a driver who will take the pizzas to their final destinations.
The drones’ home base will be a Pizza Hut located in Bnei Dror in Northern Israel, and will allow the restaurant to provide delivery service to an additional 7000 households. The Ministry of Transportation has limited the drones’ flight area to about 50 square miles, and each drone’s limited battery life means there’s little chance of one going rogue.
Billionaires Elon Musk, Jeff Bezos, and Richard Branson all want to send private citizens to space. Their respective companies, SpaceX, Blue Origin, and Virgin Galactic are dedicated to making space travel and space tourism more accessible.
Narrator: SpaceX, Blue Origin, and Virgin Galactic are in a modern space race. Similar to when the United States and the Soviet Union competed to get astronauts on the moon, these billionaire-run companies are racing to bring people like you and me to space. But how will they do it?
Let’s start with Blue Origin, the passion project of Amazon CEO Jeff Bezos. Blue Origin’s focus is on commercial space flight, or space tourism. It plans to shoot a booster rocket with an attached passenger capsule to 60 miles above the surface into sub-orbital space. At the top of the rocket’s arch, the capsule will detach, and for about four minutes, passengers will experience weightlessness. They’ll be allowed to unbuckle their seat belts and float around the cabin, looking out the window at the curvature of the Earth. The capsule will then start to fall back into the atmosphere, and parachutes will deploy to bring it down slowly. The whole trip only lasts about 11 minutes. A ticket on Blue Origin’s New Shepard will likely cost more than $200000. That’s over $18000 a minute. Blue Origin has tested the New Shepard rocket nine times, and the company still hopes to send civilians into space in 2018.

Scientists in Florida have developed process to create methane using aerobic digester.
The Milky Way houses 8292 recently discovered stellar streams—all named Theia. But Theia 456 is special.
A stellar stream is a rare linear pattern—rather than a cluster—of stars. After combining multiple datasets captured by the Gaia space telescope, a team of astrophysicists found that all of Theia 456’s 468 stars were born at the same time and are traveling in the same direction across the sky.
“Most stellar clusters are formed together,” said Jeff Andrews, a Northwestern University astrophysicist and member of the team. “What’s exciting about Theia 456 is that it’s not a small clump of stars together. It’s long and stretched out. There are relatively few streams that are nearby, young and so widely dispersed.”
Engineers at the Johns Hopkins University Applied Physics Laboratory are prototyping a previously theoretical rocket design that could someday take spacecraft to interstellar space. Their plan? Use heat from the sun, rather than combustion, to power a rocket engine.
🌌 You love badass space stuff. So do we. Let’s explore the universe together.
The 14th launch of a New Shepard rocket will send a space capsule past the edge of space to test the system ahead of its first passenger flights.
In 2012, the Gateway Foundation was founded with the purpose of building the world’s first rotating space station in orbit – known as The Gateway. This is no easy task and must be preceded by establishing the necessary infrastructure in orbit and the creation of a series of smaller structures to test the concept. This includes the Voyager Class station, a rotating structure designed to produce varying levels of artificial gravity.
In recent months, the Orbital Assembly Corporation (OAC) – founed in 2018 by the Gateway team – began working on a crucial component, known as the DSTAR. These and other updates about their Voyager Class station were the subjects of a recent video featuring Foundation and OAC CEO John Blincow. According to Blincow, he and his colleagues will be performing a demonstration and making a big announcement in the coming weeks!
The design for The Gateway was inspired by the Von Braun Wheel, a proposal made by German rocket scientist and space architect Wernher von Braun. This, in turn, was inspired by earlier concepts like the pinwheel space station prosed by Russian scientist and “father of astronautics” Konstantin Tsiolkovsky. In 1903, he released a treatise titled, Exploration of Outer Space by Means of Rocket Devices.
