Scientists believe that oxygen was formed during the birth and development of the stars after the Big Bang… Take a breath and exhale!

1. Everybody is a star

Look up at the sky at night. Try to get far away from the lights of the city, where the stars and their constellations can really twinkle in the ­darkness. Then consider these facts: 1. After hydrogen and helium, oxygen is the ­universe’s most common element. 2. Our body consists of about two-thirds oxygen. 3. More than one-fifth of our atmosphere is made up of oxygen. 4. Scientists believe that oxygen was formed during the birth and development of the stars after the Big Bang. Take a breath and exhale. See how the sky glimmers. And then try to grasp the fact that your body is crafted from a material forged during the birth of the stars.

2. Oxygen deluxe

It is said that celebrities such as Madonna inhale puffs of pure oxygen that sharpen the senses. The treatment is now available at luxury hotel chains such as the Ritz-Carlton, which stocks Oxygen Plus (O+). O+ that consists of a compact tube containing 95 percent oxygen that can be used by visitors cities with polluted air, according to specialist travel website Luxury Daily.

3. Grow your own

Three house plants that have purifying powers. As well as being particularly good at transforming carbon dioxide into oxygen, the Areca Palm has the ability to remove specific pollutants from the air. Mother-in-law’s Tongue, also known as the Bedroom Plant, has the remarkable ability to produce oxygen throughout the night. In addition, it has been recognised by Nasa for its ability to filter carcinogenic benzene – which is found in cigarette smoke, dyes and plastics – from the air. A Money Plant is a living, miniature treatment facility, filtering dangerous pollutants from the air. It needs watering only once a week.

4. The two discoverers

The element oxygen was actually discovered twice. In the 1770s, both the Swedish chemist Carl Wilhelm Scheele and the Englishman John Priestley produced oxygen in their laboratories, entirely independently of one another.

5. No filter

Researchers find a way to measure air quality through Instagram.

A group of researchers at Nanyang University in Singapore has come up with a method of measuring air quality by analysing social media feeds. Each year more than three trillion images are uploaded on Instagram, Facebook and Twitter. Researchers found that by analysing the images they could begin to gain an insight into our climate.

Careful study can reveal patterns in the weather systems that they depict. Interaction between air masses in different locations can also be seen, thanks to the ­geographical spread of ​​social media usage. Fortunately, the method can be automated. As it gets rolled out more widely, it will likely tell us a great deal more about our future climate.

6. Our modest hero

The oxygen molecule O2 has no smell and is invisible to the naked eye, but it is essential for life in both the water and on land. In contrast, its highly toxic cousin ozone, ­designated O3, is much more flagrant, ­announcing its presence with a sharp odour.
