There are certain aspects of it that look more complicated than they are because you are seeing it as a representation on a flat map. It makes a lot more sense when you see it on a globe with all the pieces moving in 3d space.
It is complicated because there are tilts to the earths rotation and a tilt to the moon’s orbit, but people thousands of years ago figured it out, so it’s solvable.
It’s impressive how much detail Juno was able to capture even on the night side. What I love about Io is how it’s instantly recognizable. Nothing even remotely resembles it in the solar system.
Evidence suggests that this feature is the projection of a shell on to the plane of the sky. Voids and string-like formations are common outcomes of large-scale structure. However, these structures have maximum sizes of 150 Mpc, which are an order of magnitude smaller than the observed GRB ring diameter. Evidence in support of the shell interpretation requires that temporal information of the transient GRBs be included in the analysis. This ring-shaped feature is large enough to contradict the CP. The physical mechanism responsible for causing it is unknown.
Weird reporting like this is “new” GRB ring out of Swift and Sloan SDSS data.
Sloan Great Wall, which is around 1.5 billion light-years in length
South Pole Wall, which stretches 1.4 billion light-years across.
Hercules-Corona Borealis Great Wall, which is about 10 billion light-years wide
It makes me so mad we don’t just tell the flight industry that by date X no planes that use traditional fuel can be produced, and by date Y that they won’t be allowed to fly. Doesn’t even need to a global agreement, if the European market is closed, than that could be motivation enough. And it would focus innovation on efficiency instead of frivolous stiff like this.
As Universe Today explored in a previous post, it would take between 19,000 and 81,000 years for a spacecraft to reach Proxima Centauri using conventional propulsion (or those that are feasible using current technology)
Acceleration is a bitch. A manned flight would take longer as it would have to cap it’s thrust to 1-1.5G or risk long term effects. Not to mention having to cancel ALLL of that thrust starting at the halfway point.
Biology is frustrating. We’re built for everything except leaving the immediate area around the sea we crawled out of. Anything beyond that and our bones melt into cancer.
If we were realistic about going to Mars, we’d start with serious plans to build an oceanic base on Earth first. Traveling to Mars is a small hurdle, in comparison to actually living there. We’d learn a lot if we built a self-sustaining base in the deep ocean.
That orbit is better described as passing through the habitable zone. How this would affect potential life, I have no clue, but it certainly isn’t a stable orbit in the habitable zone like earth or mars
Another article said it had 6.6 times earth’s mass, and now I’m really curious about the diameter and atmospheric composition. It sounds like it’d be a big Venus that alternates between freezing and boiling.
