Dec 3, 2023 · But life on Earth will end much, much sooner than that. Earth will become unlivable for most organisms in about 1.3 billion years due to the sun's natural evolution, experts told Live...

After 8 billion years of happily burning hydrogen into helium are over, the sun’s life gets a little more interesting. Things change because the sun will have run out of hydrogen in its core – all that’s left is the helium. The trouble is that the sun’s core is not hot or dense enough to burn helium. In a star, gravitational force pulls all the gas...
It is widely understood that the Earth as a planet will not survive the sun’s expansion into a full-blown red giant star. The surface of the sun will probably reach the current orbit of Mars – and, while the Earth’s orbit may also have expanded outwards slightly, it won’t be enough to save it from being dragged into the surface of the sun, whereupo...
This 10% increase in the sun’s brightness, triggering the evaporation of our oceans, will occur over the next billion years or so. Predictions of exactly how rapidly this process will unfold depend on who you talk to. Most models suggest that as the oceans evaporate, more and more water will be present in the atmosphere instead of on the surface. T...
Earth is passing through an ice age known as the quaternary glaciation, and is presently in the Holocene interglacial period. This period would normally be expected to end in about 25,000 years.
Sep 28, 2023 · Scientists estimate that the end of the world will happen about a billion years from now, specifically in the year 1,000,002,021. By then, the sun's radiation will vaporize Earth's atmosphere, absorbing all of the oxygen, which will kill all life forms, leaving behind a barren rock.
Apr 17, 2023 · Long after that – about 5 billion years from now – our Sun will expand into an even bigger star that astronomers call a “red giant,” which eventually will engulf the Earth.
Jul 14, 2016 · A handful of researchers, however, persist in thinking the unthinkable. With enough knowledge and proper planning, they say, it's possible to prepare for—or in some cases prevent—rare but devastating natural disasters. Giggle all you want, but the survival of human civilization could be at stake.
