Scientists are concerned, because HFC-23 is a very potent greenhouse gas, with one tonne of its emissions being equivalent to the release of more than 12,000 tonnes of carbon dioxide.
The star will go supernova at the end of its life, but that’s not projected to happen for tens of thousands of years or so. However, the great dimming of Betelgeuse continues.
Malaysia will no longer allow other countries to dump their plastic waste on its land. The country has successfully returned 150 containers of plastic waste to 13 mostly wealthy nations since the end of last year.
In Egypt, a number of mysterious inscriptions and examples of rock art have been found in the Sinai. It is estimated that some of the images could be 12,000 years old.
Using advanced microscopy methods, scientists captured a moment of breaking of a chemical bond, around half a million times smaller than the width of a human hair. We are now the first generation of humans to have seen atoms.
Plastic bricks made via a recycling process developed by a Colombian social enterprise are being used to help tackle a huge shortfall of classrooms in the West African nation of Ivory Coast.
The number of people who are talking about fossil fuels as a real concern has increased dramatically over the last 12 to 24 months. Awareness of these issue may be growing, but global emissions are continuing to rise.
A meteorite that crashed into Australia back in 1969 contains interstellar stardust dating back some 7 billion years, predating the formation of Earth by 2.5 billion years. The discovery offers a snapshot of the conditions that existed before our solar system.
Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.
The largest spiral galaxy in the local universe UGC 2885, is 2.5 times wider than the Milky way and hosts a trillion stars, 10 times more than Earth’s galactic home. UGC 2885 is located some 232 million light years away in the constellation Perseus.
The habitable-zone planet is one of three orbiting a star known as TOI 700, a cool M dwarf located about 100 light-years from Earth. The candidate planet, TOI 700 d, is is at a distance where temperatures would allow water to exist in liquid form.
This star is going to go nova (not supernova) by 2083. V Sagittae is in the constellation Sagitta and is s about 1100 light years from Earth. When the brightening happen, it will be historic. V Sge will appear startlingly bright in the night sky.
Astronomers have found six objects orbiting Sagittarius A* that are unlike anything in the galaxy. These objects look like gas but behave like stars. They are so peculiar that they have been assigned a brand-new class - what astronomers are calling G objects.
NASA released a radar animation that shows smoke from the fires 6,800 miles away in Chile. The skies over Chile have turned grey and hazy. Argentina has also seen sunsets tinged with red from the smoke.
Cement production is one of the world’s leading contributors of CO2 emissions. Now, US researchers have combined sand, a hydrogel, and bacteria into a living material that has similar strength to cement-based mortar.
