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.
JetBlue has announced that it will offset carbon dioxide emissions from jet fuel for all domestic flights beginning in July 2020, making it the first major US airline to take the step toward reducing its contribution to global warming.
CES is the world's gathering place for all those who thrive on the business of consumer technologies. Here are the this year's highlights including robots and wearable devices.
In 2018, a large number of seismic alerts had been detected everywhere. They created a weird buzzing sound. Now the mysterious hum is identified as rumblings of a magma-filled reservoir deep under the Indian ocean where the new volcano is forming.
The Australian Bureau of Meteorology (BOM) has released its annual climate statement for 2019, and found that last year was both the hottest and driest on record for the continent.
Scientists have uncovered a new kind of electrical process in the human brain that could play a key role in the unique way our brains compute.Researchers have discovered that certain cells in the human cortex transmit signals in a way not seen before.
Beech Street, much of which runs under the Barbican Estate, will now be restricted to zero emission vehicles, cyclists and pedestrians by Spring 2020. The experiment will run for 18 months, during which time the impact on air quality and traffic will be monitored.
2019 was the cleanest year on record for Britain as, for the first time, the amount of zero carbon power surpassed fossil fuel generation for a full twelve months.
