Discover everything you need to know about the universe, from the Big Bang to its ultimate destiny, in the Ultimate Fate of the Universe 131, now on sale.
In this cover feature, All About Space meets the people behind the experiment looking for an answer to how our universe began. From reproducing the big band at the European Nuclear Research Organization (CERN) using a large Hadron Collider that crushes particles to observing the aftermath at the Institute of Space and Astronautical Science in Maryland.
The latest issue seeks to answer questions such as whether you will notice when the expansion of the universe stops. Or how do you know that the universe is the color of cosmic latte?

Elsewhere in this issue, you can find a detailed planetary profile of Jupiter. The gas giant has a lot to talk to us and Juno is in the case.
The latest issue also includes an interview with Christopher J. Ferguson, a former US Navy captain and NASA astronaut currently working at Boeing. He is using CST-100 capsules to help build a new generation of spacecraft under a contract from NASA.
There is also a detailed Stargazer section full of useful information on what to watch out for in the sky, such as targets for the naked eye and binoculars, and a guide to getting the best view of the solar system.

The universe explained
(Opens in a new tab)
The universe seems to have come out of almost nowhere. The combination of high temperatures and thick groups of exotic particles enters the overdrive of expansion through several phases of different conditions, creating the universe as it is today, about 13.8 billion years later. The Big Bang, the Creator of Time and Space — or at least, our current understanding of how our universe came to exist is what makes us believe.
But what we learned about the somewhat mysterious past of the universe did not always go back to the days of Georges Lemaître, later called the father of the Big Bang theory. Based on the solution of Albert Einstein’s equations, a Belgian priest, astronomer, and professor of physics suspected in 1927 that the universe ignited life at some point before confronting expansion head-on. It must have been.

Uncover the secrets of the Antikythera mechanism
(Opens in a new tab)
In 1900, sponge diver Elias Stadiatis made an amazing discovery off the coast of Antikythera, Greece. Lying in front of him were like rotten corpses and horses scattered on the seabed in the wreckage of a Greek wreck. It didn’t take long to understand what Stadiatis saw after a team of divers was dispatched later that year. A treasure trove of bronze and marble statues, some of which date back to the 4th century BC. But the divers didn’t know they had regained something more remarkable.
In 1901, an object about the size of a large book was discovered in the depths of a shipwreck. The following year, archaeologist Spiriton Stace happened to see a book-sized chunk and began to crumble. He could then see corroded pieces of bronze with precision gears embedded in them, but most of the techniques were obscured by corrosion.

How are the aurora formed on other planets?
(Opens in a new tab)
A shimmering aurora, or aurora, is a show of natural light that occurs in a loop around a pole. The southern version is known as Aurora Aurora. Auroras occur when charged particles (solar wind) emitted from the sun collide with the upper atmosphere. It is a mixture of electrons, protons, and helium nuclei that loses energy when it collides with gas molecules in the atmosphere. These gas molecules are ionized and some of the electrons are separated, forming a plasma in which the gas glows.
Gas mixing dominates the colors we see. Red is produced by low concentrations of oxygen in the highlands. It turns green as the oxygen density increases, and nitrogen produces a blue color. Pink, yellow and orange are all observed, probably because the amounts of red, green and blue are different.
