Elements

Everything around us contains material that was once part of a star. The cells in our bodies, the air we breathe, and materials that make up the planets in our solar system are all linked to the stars through chemical elements.

Hydrogen and helium are the two most abundant elements. They were made in the Big Bang more than 13 billion years ago. Others, like oxygen and iron, are created deep inside stars. Supernova explosions blast them into space and form even heavier elements, such as gold and uranium.

Everyday Elements

Chemical elements are the building blocks of everything. The Sun and stars, the silicon chips in our computers, and all the cells in our bodies are collections of elements.

Hydrogen is the lightest and most plentiful element. It has one proton, one electron, and an atomic number of 1. It was created in the Big Bang, along with helium. The other elements up to uranium (number 92) are made in stars.

Elements Made by People

When physicists smash smaller atoms together during experiments in nuclear accelerators and reactors, they create elements that have atomic numbers higher than 92. Neptunium, californium, and plutonium (which is used in spacecraft power supplies) are good examples of these elements. Scientists also study the tracks atomic particles make in bubble chambers during high-speed experiments (right).

Formation and Distribution

Big Bang

The nuclei of the three most basic and plentiful elements in the universe began forming during the first 100 seconds after the Big Bang.

Stars

Atomic reactions deep inside stars combine atoms to form many of the familiar elements that make up planets, stars, galaxies, and us.

Supernovae

The extremely high temperatures and pressures inside exploding stars help create the heaviest elements. Supernova explosions scatter them throughout space.

Humans

Our bodies contain more than two dozen elements. We are made of material that was created in stars.

Gases

Most elements are solids and liquids at room temperature. Eleven are gases.

Stars, People, and Atoms

Elements in Us

The human body is mostly hydrogen and oxygen, with traces of other elements (color coded to the elements table).

How Elements Reach Our Bodies

If you want to know where most elements originate, look at the night sky. Most of the stars and all the planets you see came from materials cooked up deep inside other stars. When those stars died, their elements were scattered into space in gas and dust clouds.

•A nebula is the graveyard of a star that exploded as a supernova. Material in the cloud may become new stars.

We, too, are part of the cosmic recycling process. It began billions of years ago inside an ancient star. The calcium in our bones, iron in our blood, and oxygen in our lungs were all created inside that long-dead star.

•Look at your hand. It is a piece of the universe. Its millions of skin cells are each made of elements from stars.

Elements are the building blocks of the universe. Atoms are the basic units of elements. Most atoms are made up of three types of particles: protons, neutrons, and electrons. Every structure in the cosmos is made of atoms from many different elements.

•Each droplet of carbon is a tenth of the width of a human hair and contains thousands of atoms.

Creation of Elements in Supernova Explosions

Thanks to stars and the elements they create, the universe renews itself. When stars die, their material gets scattered through space as the seeds for new generations of stars. The heaviest elements are created in huge stellar explosions like Supernova 1987a (left). Temperatures and pressures in these outbursts are so high that atoms fuse to make more complex elements, such as lead, gold, and uranium.

The Fingerprints of Elements

Light from celestial objects identifies the chemical elements they contain. Each element has a specific fingerprint, which we can see with a spectroscope. Helium and neon are made inside stars. Helium’s spectral fingerprint is simple, while neon has many more lines. Elements like krypton and mercury are created in supernova explosions.

Atomic reactions deep inside stars combine atoms to form many of the familiar elements that make up planets, stars, galaxies, and us.

Supernovae

The extremely high temperatures and pressures inside exploding stars help create the heaviest elements. Supernova explosions scatter them throughout space.

Humans

Our bodies contain more than two dozen elements. We are made of material that was created in stars.

Gases

Most elements are solids and liquids at room temperature. Eleven are gases.

Stars, People, and Atoms

Elements in Us

The human body is mostly hydrogen and oxygen, with traces of other elements (color coded to the elements table).

How Elements Reach Our Bodies

If you want to know where most elements originate, look at the night sky. Most of the stars and all the planets you see came from materials cooked up deep inside other stars. When those stars died, their elements were scattered into space in gas and dust clouds.

•A nebula is the graveyard of a star that exploded as a supernova. Material in the cloud may become new stars.

We, too, are part of the cosmic recycling process. It began billions of years ago inside an ancient star. The calcium in our bones, iron in our blood, and oxygen in our lungs were all created inside that long-dead star.

•Look at your hand. It is a piece of the universe. Its millions of skin cells are each made of elements from stars.

Elements are the building blocks of the universe. Atoms are the basic units of elements. Most atoms are made up of three types of particles: protons, neutrons, and electrons. Every structure in the cosmos is made of atoms from many different elements.

•Each droplet of carbon is a tenth of the width of a human hair and contains thousands of atoms.

Creation of Elements in Supernova Explosions

Thanks to stars and the elements they create, the universe renews itself. When stars die, their material gets scattered through space as the seeds for new generations of stars. The heaviest elements are created in huge stellar explosions like Supernova 1987a (left). Temperatures and pressures in these outbursts are so high that atoms fuse to make more complex elements, such as lead, gold, and uranium.

The Fingerprints of Elements

Light from celestial objects identifies the chemical elements they contain. Each element has a specific fingerprint, which we can see with a spectroscope. Helium and neon are made inside stars. Helium’s spectral fingerprint is simple, while neon has many more lines. Elements like krypton and mercury are created in supernova explosions.

This is the 6th column in Robin Bell’s description of authentic analysis in Antarctica in backward 2008 and aboriginal 2009.

At aftermost we are able to arise flights out of AGAP S. With the collapsed white cartography all about us it is adamantine to anticipate a abundance ambit anywhere abreast us. Our flight from the South Pole located some accessory 100 basal peaks abutting to camp, but these are not the ambit we are attractive for. Our plan involves analysis below the ice to the arctic with the aerial radar. The abstracts on the flights amid South Pole and the affected let us apperceive the systems assignment able-bodied over the blubbery algid ice. Although we accept activated the system, aboriginal in Greenland this accomplished summer, and again at McMurdo already in Antarctica, there was a affair that it ability not assignment at this colder environment.

The alarm arrangement that makes the abstracts profiles transmits activity from four antennae on the appropriate addition of the aircraft and annal the abiding echos from the ice on the four antennae on the larboard wing. While alarm systems are broadly acclimated in ecology engineering for belief the high 1-10 meters of the apple surface, alarm can be acclimated to map through 4-5 kilometers of ice. The electrical application of ice makes alarm a absolute tool. The aboriginal answer absolutely campaign beeline admitting the air from one ancillary of the aircraft to another. The additional answer is from the apparent of the ice sheet. We can use this arrangement to map crevasses, mega dunes and amphibian ice over lakes, although our laser arrangement will be added accurate.

Within the ice breadth there are changes in electrical application as a aftereffect of the alteration architecture of the ice – sometimes the aftereffect of agitable dust landing on Antarctica. These actinic changes appearance up as abounding layers aural the ice sheet, layers evocative of a adorned band cake. The final answer is from the basal of the ice sheet. Rocks will acknowledgment a signal, but baptize at the basal of the ice breadth will acknowledgment a absolutely able signal. The able reflectivity of baptize makes lakes accessible to spot.

A ample basin has emerged beneath three km of ice, and the mountains are alpha to appear basic a map of what is beneath the all-encompassing ice sheet. Our analysis breadth is alert as big as the accompaniment of California. A ample breadth to awning but admitting the setbacks we are assuredly capturing the images we had hoped for!

Robin Bell is a geophysicist and analysis scientist at Lamont-Doherty Apple Observatory of Columbia University. She has accommodating seven above aero-geophysical expeditions to Antarctica belief subglacial lakes, ice bedding and the mechanisms of ice breadth movement and collapse, and currently the Gamburtsev Mountains, a ample alp sized subglacial abundance ambit in East Antarctica.
