Planets Around Wolf 1061 Key To Understanding ‘Venus’
The inner edge of the habitable zone is the dividing line between peaches and cream and all out hell. Venus has likely seen both. The study of exo-solar systems like Wolf 1061 is key to understanding our own Venus.
New observations of the nearby star Wolf 1061, some 14 light years distant in Ophiuchus — already known to harbor three super-earths — should help planetary scientists better understand what went wrong with our own Venus.
Turns out hellishly-hot Venus-like worlds are quite common and early in the history of any given planetary system, such close-in terrestrial mass planets might even sport liquid water. But as their host stars evolve, the perilous inner edge of these extrasolar planetary systems’ habitable zones move decidedly outward.
As a star’s luminosity grows over time, such tenuous habitable zones can cause what might have been a promising climate to turn into a runaway greenhouse of the sort we see on Venus. With no liquid water at its surface, Venus is the very definition of inhospitable. That’s in contrast to a habitable clime where given the right atmospheric pressure and temperatures terrestrial mass planets can host temperate liquid water on their surfaces.
IT’s Real: Metallic Hydrogen Has Been Created for the First Time
More than 80 years after it was first predicted, physicists have created metallic hydrogen — a mysterious form of hydrogen that could be capable of superconducting electricity without resistance at room temperature.
Scientists have long suspected that hydrogen could exist as a metal in certain parts of the Universe, but this is the first time metallic hydrogen has ever been created on Earth, and the material is even stranger and more fascinating than scientists imagined.
“This is the holy grail of high-pressure physics,” says lead researcher Isaac F. Silvera from Harvard University. “It’s the first-ever sample of metallic hydrogen on Earth, so when you’re looking at it, you’re looking at something that’s never existed before.”

IBM Just Posted 5 Predictions About What Life Will Be Like in 2022
Technology giant IBM is known for of making bold predictions about the future, and it’s just announced its latest “5 in 5” list, highlighting the five innovations that they think will have the biggest impact on our lives over the next five years.
According to the company, in only a few years, we’re set to see huge developments in artificial intelligence (AI), ultra-powerful telescopes, smart sensors, and medical devices — with benefits ranging from healthcare and the environment, to our understanding of Earth and the Universe itself.
Of course, all these predictions are based on technology and research developments that are happening right now — there’s no way of knowing what else might crop up in the next five years.
Technology for making Death Star Sized Structures will have technical feasibility in the next 20 years
I never heard of this sort of making bubbles. And the details given are slim. Anyone here of this?
The first Death Star had a diameter of between 140 and 160 kilometers. The second Death Star’s diameter ranged from 160 to 900 kilometers.
There are two near term technologies which could be applied to making Death Star sized structures:
1. Space bubbles
2. Robotic spiderfab construction
