Sugar Found in Space Around Young Sun-like Star

A team of astronomers has made a sweet discovery. Astronomers has spotted sugar molecules in the gas surrounding a young Sun-like star, using the powerful telescope Atacama large millimeter/sub-millimeter array (ALMA), suggesting the possibility of life on other planets and it also suggests that some of the chemical compounds needed for formation of life can present before even planets exist.

The space sugar molecules, known as Glycoaldehyde is a simple form of sugar which are made up of carbon, hydrogen, and oxygen that can be found on the form of an odorless white powder, and also this molecule is one of the ingredients in the formation of RNA – one of the building blocks of life, one of the most crucial molecules present in living cells. Previously, sugar molecules has been detected in two other places in interstellar space but both of these regions are much further away and were observed with much worse resolution and it wasn’t possible for the astronomers to pinpoint the location of the molecules. According to the researchers, this is the first time sugar molecules has been spotted so close to a Sun-like star, at distances comparable to the distance of Uranus from the Sun in the Solar System.

Now, the big question is how complex can these molecules become before they are incorporated into new planets, or whether it is common that these organic molecules are formed so early in the star and planet formation process? This could explain something about how life might arise elsewhere.

and The Reason is Here – The Universe and Connection

How we are all interconnected?This post is just a brief explanation of my last post. The post where I’ve written “The universe is full of wisdom and if you try to learn about it a little, if you try to understand about it a little then at some point it will teach you how we all are connected with each other and with all the things. In the period you try to understand about the universe, you will suddenly realize how a single perception, how a single conception plays a role in the humans life.”

There are reasons why I’ve written that and if you really want to know the reasons behind it then read the following things.
I’m just trying to explain it as briefly as I can. So, here’s it:

How can you say that we are made up of atoms? The answer to this question is not much difficult. We know that cells are made up of molecules, molecules are made up of atoms; humans and all the beings are made of cells and hence, we are made of various molecules and atoms. Now from where did these atom come from and how were they made? The answer to these questions lies in the creation of the universe. Long ago when the universe formed, at that time subatomic particles assembled into atoms and they formed hydrogen atoms. Hydrogen, the first element ever formed in the universe, the simplest type of atom. After that as the universe aged other elements were also created and that’s why it is said that every element on earth, except for the lightest was created in the some massive stars.

Now, we can say that every element in the periodic table aside from hydrogen is essentially a stardust as hydrogen is a big bang dust. So, lets see how much we are made up of stardust, and to know that we have to exclude hydrogen as it’s a big bang dust not a stardust.

Our body is composed of billions of billion atoms and in all these atoms some of them are hydrogen. Most of the hydrogen in our body floats around in the form of water and water usually makes up 55%-78%(approx.) of the human body and hydrogen only accounts for 11% of that water mass and from this, we can say that 92.5-93.7%(approx.) of the mass in our body is stardust. Hence, we are all made up of stardust and if you include hydrogen too then we are all made up of atoms, which were created in the universe long ago. Calcium in our bones, Iron in our blood, all were created in some massive stars!

However, I’m well aware of the fact that the truth can be a lot different from the theories, physics, philosophies, facts, understanding or everything and it can be a lot crazier and astonishing than we can even imagine. But so far, this is what I think about us and the universe, this is what I’ve learned and it fits into my understanding.
