Astronomers have detected 72 incredibly bright and quick events flashing across a recent sky survey – and they’re struggling to understand where they came from. The mysterious explosions are similar in brightness to supernovae – the final, gigantic explosions that extinguish stars.   But supernovae can be seen lighting up the sky for several months…

Black holes are vast, matter-annihilating objects that seem to defy physics by their very existence. They’re so weird, that when Albert Einstein’s equations first predicted the existence of these beasts, he didn’t believe they could actually be real.   And you can’t really blame him, because the idea that we have these singularities of space-time…

The most remote location on Earth has many names: It’s called Point Nemo (Latin for ‘no one’) and the Oceanic Pole of Inaccessibility. Most precisely, its exact coordinates are 48 degrees 52.6 minutes south latitude and 123 degrees 23.6 minutes west longitude.   The spot is about 2,250 km (1,400 miles) from any spot of…

The Chinese space station called Tiangong-1 is expected to crash to Earth within hours. The 9.4-ton spacecraft went up into space in 2011, but in 2016, the Chinese government lost communication with it due to an apparent technical malfunction.   It’s been difficult to predict the precise moment when Tiangong-1 will re-enter Earth’s atmosphere, and where it will break up into…

When Tiangong-1 rocketed into the sky in 2011, optimists hoped the space station – literal translation: “heavenly palace” – would be a model for a permanent fixture among the stars, a space laboratory that was among humankind’s first footsteps in the Cosmos.   So, when an out-of-control Tiangong-1 comes plummeting to earth in a superheated…

By applying methods used to evaluate the chances of life on other planets, scientists have concluded that Earth is indeed inhabitable – but it’s also becoming increasingly polluted by levels of carbon dioxide and methane.   The inspiration for the new research is an experiment run by Carl Sagan and his team back in the…
