Solar Total and Spectral Irradiance Reconstruction Over The Last 9,000 Years

Solar Total and Spectral Irradiance Reconstruction Over The Last 9,000 Years

Changes in solar irradiance and in its spectral distribution are among the main natural drivers of the climate on Earth. However, irradiance measurements are only available for less than four decades, while assessment of solar influence on Earth requires much longer records.

New Theories For The Origin Of Earth's Water

New Theories For The Origin Of Earth's Water

Earth's water may have originated from both asteroidal material and gas left over from the formation of the Sun, according to new research. The new finding could give scientists important insights about the development of other planets and their potential to support life.

Evidence of Outburst Flooding Indicates Plentiful Water on Early Mars

Evidence of Outburst Flooding Indicates Plentiful Water on Early Mars

The presence of water on Mars has been theorized for centuries. Early telescopes revealed ice caps, and early astronomers noted channels that were hypothesized to be natural rivers or creature-created canals.

Existing Laser Technology Could Attract Alien Astronomers

Existing Laser Technology Could Attract Alien Astronomers

If extraterrestrial intelligence exists somewhere in our galaxy, a new MIT study proposes that laser technology on Earth could, in principle, be fashioned into something of a planetary porch light -- a beacon strong enough to attract attention from as far as 20,000 light-years away.
