End of the world update nasa

More info. Doomsday predictions are rife as edges closer each day, despite their limited evidence. Figures throughout history have cast their prophecies on events that claim to be the beginning of the end of the world. Nostradamus, while not predicting entirely apocalyptic events, is perhaps one of the world's most famous "seers".

Some have wildly claimed that one of his predictions spells disaster for the Earth in through an asteroid collision. Yet, Nostradamus did describe a "celestial stone" falling to Earth, with a "great fire" following. However, she said: "But in the long run, the two most important factors are tropospheric temperature and stratospheric temperature.

The unchecked burning of fossil fuels since the dawn of the industrial revolution has caused global temperatures to climb at an alarming rate. NASA estimates the planet has warmed by a little more than 1C 2F since and many projections show the global warming will continue unless something is done to curb greenhouse emissions. Greenhouse gases, like carbon dioxide CO2 and methane CH4 are being pumped into the atmosphere where they trap heat and cause the troposphere to rise.

According to the new study, the troposphere has risen by about the same rates between and , and and - about ft 50m per decade. Professor Liu said: "All the observational data over this four-decade period of time tell us the same thing. Changes to the troposphere can affect the amount of water vapour in the atmosphere which, in turn, can further affect Earth's surface temperatures.

They're not too cold, not too hot, just right for water — but only if they have hospitable atmospheres. Webb will watch potentially habitable exoplanets pass in front of their stars, and analyze the spectra of starlight that shines through the planets' atmospheres.

That spectroscopy will indicate to scientists whether the air on other worlds contains compounds that could point to life, like carbon dioxide, methane, or water. These aren't necessarily Earth-like planets. Stars like the sun are so big and bright that Webb wouldn't be able to see the tiny Earth-like planets orbiting them.

That's a job for the next great space telescope. Instead, Webb will look at rock planets orbiting stars that are much smaller and dimmer. The star has seven rocky planets, three of them in its "Goldilocks zone," meaning they're just the right distance to have temperatures that would allow liquid water to exist on their surfaces. Webb is also set to zoom in on uninhabitable, but fascinatingly extreme, planets. At least one of the planets on its roster is so close to its star that its surface is molten, and it may even rain lava there.

Webb should be able to detect that lava rain. The telescope will also examine every object in our solar system, starting with Mars and working its way outward to the icy objects beyond Pluto. In those planets, stars, and galaxies, near and far, Webb is sure to uncover major surprises. This post has been updated with new information. It was originally published on December 11, For you.
