After Just 6 Weeks of Construction, Super Heavy is Built and Ready to Move
As usual, the SpaceX South Texas Launch Facility, located near the village of Boca Chica, is the focal point of a lot of attention. Almost two months ago, crews at the facility began working on the first true Super Heavy prototype, the launch stage of SpaceX’s Starship. After six weeks of assembly, SpaceX rolled the Super Heavy Booster 3 (B3) out of the “High Bay” (where it was assembled) and installed it onto the launch pad.

The "Crisis in Cosmology" Might not be a Crisis After all
The standard model of cosmology is known as the LCDM model. Here, CDM stands for Cold Dark Matter, which makes up most of the matter in the universe, and L stands for Lambda, which is the symbol used in general relativity to represent dark energy or cosmic expansion. While the observational evidence we have largely supports the LCDM model, there are some issues with it. One of the most bothersome is known as cosmic tension.

Satellites can Track Microplastics From Space
Sometimes simple and elegant solutions are all that is needed to solve a problem. One problem that was searching for a solution was how to track microplastics. These small particles of plastics are what results after the sun and friction (such as ocean waves) break down larger plastic objects. They have become a huge problem in the ocean, wreaking havoc on ecosystems and their constituent organisms. Now, a team from the University of Michigan have used data originally collected to monitor hurricanes to try to track microplastics, potentially helping to reign in a problem that threatens to engulf the world’s oceans.
One of the Brightest Star-Forming Regions in the Milky Way, Seen in Infrared
Certain parts of the galaxy are more magical than others. There are barren wastelands where barely a particle strays through occasionally, and there are fantastical nebulae that can literally light up the sky. But beyond their good looks, those nebulae hold secrets to understanding some of the most important features of any galaxy – stars. Now, for the first time, a team from the University of Maryland managed to capture a high resolution image of one of the most active star-forming regions in our part of the galaxy. Data from that image are not only spectacular, but can illuminate the details of the star formation process.
