Serious We are actually a bunch of STARDUST! Are we aliens? ET?

Are we really all made of stardust?
We are all made of stardust. It sounds like a line from a poem, but there is some solid science behind this statement too: almost every element on Earth was formed at the heart of a star.

Next time you’re out gazing at stars twinkling in the night sky, spare a thought for the tumultuous reactions they play host to. It’s easy to forget that stars owe their light to the energy released by nuclear fusion reactions at their cores. These are the very same reactions which created chemical elements like carbon or iron - the building blocks which make up the world around us.

After the Big Bang, tiny particles bound together to form hydrogen and helium. As time went on, young stars formed when clouds of gas and dust gathered under the effect of gravity, heating up as they became denser. At the stars’ cores, bathed in temperatures of over 10 million degrees C, hydrogen and then helium nuclei fused to form heavier elements. A reaction known as nucleosynthesis.

This reaction continues in stars today as lighter elements are converted into heavier ones. Relatively young stars like our Sun convert hydrogen to produce helium, just like the first stars of our universe. Once they run out of hydrogen, they begin to transform helium into beryllium and carbon. As these heavier nuclei are produced, they too are burnt inside stars to synthesise heavier and heavier elements. Different sized stars play host to different fusion reactions, eventually forming everything from oxygen to iron.

During a supernova, when a massive star explodes at the end of its life, the resulting high energy environment enables the creation of some of the heaviest elements including iron and nickel. The explosion also disperses the different elements across the universe, scattering the stardust which now makes up planets including Earth.

I like sipping on my cuppa while listening to Nat King Cole's Stardust. Life's simple pleasures :smile::smile::smile:

Stardust only explained the physical part of our being. What about that packet of energy that continues to exist after our destruction of the physical body (aka death).

Went to so many wakes this January alone... really can't get pass Tua Jit Jih...

New research has confirmed what scientists have been saying for years: humans are undeniably made of stardust.

A team of astronomers from the Sloan Digital Sky Survey in New Mexico enlisted the Apache Point Observatory Galactic Evolution Experiment (APOGEE) which uses infrared wavelengths to see through the galaxy's dust and analyze the composition of 150,000 stars across the Milky Way.

With that data, the group then cataloged the abundance of ‘CHNOPS’ (carbon, hydrogen, nitrogen, oxygen, phosphorous and sulfur) elements in each of the stars, which they say represent the “building blocks” of the world around us, and found humans and their galaxy have about 97 percent of the same kind of atoms.

"This instrument collects light in the near-infrared part of the electromagnetic spectrum and disperses it, like a prism, to reveal signatures of different elements in the atmospheres of stars," a Sloan spokesperson said in a statement.

The team used a spectroscopy method to evaluate each element and determine what it was made of, discovering a distinct wavelength of light from within each star.

Researchers found a stronger concentration of the elements of life in the Milky Way’s center and discovered that while we share most elements with stars, humans’ mass is 65 percent oxygen, in contrast to the less than 1 percent measured in space.

"It's a great human interest story that we are now able to map the abundance of all of the major elements found in the human body across hundreds of thousands of stars in our Milky Way," said Jennifer Johnson, the science team chair of the SDSS-III APOGEE survey and a professor at The Ohio State University.

"This allows us to place constraints on when and where in our galaxy life had the required elements to evolve, a sort of 'temporal galactic habitable zone.”

Instead of Stardust, you can listen to David Bowie's Starman at Starbucks. :biggrin:
