Swarms of Satellites Around the Sun Could Supply Us With Unlimited Power

Posted by in categories: alien life, engineering, physics, satellites

This sci-fi megastructure has captivated big thinkers for decades. A leading expert in astrobiology tells us how to construct one.


The paper focused more on theory than engineering, and Dyson provided scant details on what such a megastructure might look like or how we might build one. He described his sphere only as a “habitable shell” encircling a star. But that was enough to captivate and inspire astrophysicists, scientists, and sci-fi writers. In some depictions, the Dyson Sphere, as it became known, appears as a massive ring encircling a star and reaching nearly to Earth. In others, the Sphere completely encases the sun, a hulking megastructure capturing every bit of that star’s energy. In addition to scientific works, Dyson Spheres have appeared in novels, movies, and TV shows—including Star Trek —as a home for advanced civilizations.

Dyson himself understood the challenges of constructing such a massive structure, and he was skeptical that it might ever happen. Nonetheless, his Sphere has stirred ambitious ideas about the future of our civilization, and it continues to be offered as a solution to some of humanity’s most dire dilemmas. Harnessing the total energy of our sun—or any star—would solve our immediate and long-term energy crisis, but when civilization gains access to the complete energy output of a star, meeting our terrestrial energy needs is just the beginning.

Did supernovae help form Barnard’s Loop?

Posted by in categories: cosmology, materials

Astronomers studying the structure of the Milky Way galaxy have released the highest-resolution 3D view of the Orion star-forming region. The image and interactive figure were presented today at a press conference hosted by the American Astronomical Society.

Led by researchers at the Center for Astrophysics | Harvard & Smithsonian, the work connects 3D data on young stars and interstellar gas around the Orion complex of star-forming regions. Analysis of the 2D and 3D images, alongside theoretical modeling, shows that supernova explosions within the last 4 million years produced large cavities in the interstellar material associated with Orion.

Exercise pill could curb food cravings for people who lack physical activity

Posted by in categories: biotech/medical, food, health

STANFORD, Calif. — An “anti-hunger” pill could be on the horizon, according to a new study. Researchers from Stanford Medicine and Baylor University have identified a molecule that keeps people from getting hungry after exercising.

In experiments, the compound dramatically reduced food intake and obesity in mice. Study authors hope to turn it into a medication that may even replace the need to go to the gym.
