Explore common misconceptions about space with All About Space Magazine

The 134th issue of Inside All About Space, out now, explores 20 myths about the universe that need to be debunked. From whether you can see the Great Wall of China from space to why a spacecraft gets hot when trying to return to Earth.

For this cover, All About Space takes a demystifying journey through the universe in an attempt to uncover common misconceptions that continue to deceive us.

The latest issue also includes a Q&A with British planetary scientist and science fiction writer Simon Morden about his obsession with Mars and his latest book of science facts about the Red Planet.

In another issue, you will learn why astronauts lose muscle mass and how life on the International Space Station affects the human body. The article also looks at how sending worms into space helps people find ways to spend more time away from Earth.

All About Space also explores how a team of MIT researchers can find the answer to reducing launch costs by building a space fuel depot. If interplanetary missions could go into orbit instead of launching all at once, it could greatly reduce the cost of individual missions. All About Space explores how such an enterprise can operate.

The magazine also takes an in-depth look at cosmic volcanoes and how they helped shape the bodies of our solar system. The article on volcanoes explores the difference between the more familiar volcanoes that erupt molten rock at high temperatures and the less familiar cryovolcanoes colloquially known as ice volcanoes.

You can also find a detailed stargazer section filled with useful information on what to look out for in the night sky. This release includes a deep sky challenge that lists the six treasures of the Autumn Milky Way. Among the richest for deep space observers, September brings star clusters, nebulae and galaxies in abundance.

Take a look below at the most important features of the 134th edition of All About Space.

20 myths about the universe debunked

Our understanding of the universe is better than ever, but there are still a number of misconceptions that manage to fool many of us. Some of the following may seem plausible, but little of it is true: the sun is a burning ball of yellow fire, and temperatures are higher in the summer months because we orbit closer than we do in winter. Mercury is the closest planet to our star, so it must be the hottest. Moon phases are caused by the Earth’s shadow, and at night we can only see one side of the Moon, so the other must be in perpetual darkness. The stars form patterns with their nearest neighbors and cluster into local constellations. The shimmering light they emit travels towards Earth in a straight line, unaffected by gravity. Comets rush past with their tails pointing in the direction they came from, and when the meteorites fall into the atmosphere, they heat up so much that it is not safe to pick them up from the ground.

How to build a galaxy

The universe is filled with galaxies. Everywhere we look, we see galaxies huddled in space, grouped into clusters and vast strata scattered throughout space-time. The Hubble Space Telescope has determined that the most distant galaxies ever seen are 13.4 billion light-years away. But these are not even the most distant galactic structures. These are the first galaxies that hold the record for distance from us. However, we haven’t seen them yet. To do this, we need infrared advances from the recently launched James Webb Space Telescope (JWST), which will be able to see galaxies as they formed just 300 or 400 million years after the Big Bang, the event that gave birth to the cosmos. .

Understanding how galaxies form is a bit like trying to put together a puzzle.

Space fuel depots

Getting into space is hard. With the engines and rockets we have now, most of the weight of a rocket at launch is in the fuel and oxidizer to overcome gravity. And if we want to go beyond Earth orbit, the problem becomes even worse. If you could feed your interplanetary mission in orbit instead of launching everything at once, the cost of individual missions could be greatly reduced. With that in mind, a team at the Massachusetts Institute of Technology (MIT) came up with an intermediate concept that could build fuel depots with traditional missions.

Led by Professor Jeffrey Hoffman, a veteran of five space shuttle missions, the group proposes using spare fuel that would be used on lunar missions anyway.
