Scientists have developed a "color key" to detect extraterrestrial life in planetary clouds

A team from Cornell University and the Carl Sagan Institute has measured spectra of colorful microorganisms in Earth's clouds, creating a color guide that will help identify biopigments as biological signatures in the clouds of cloudy exoplanets.

Rain at the time

  • One response
Recent research has shown that in the future there will be fewer rainy days in our region due to the climate crisis, but there will be more strong rain events. How can this be explained using simple scientific principles?

Forecasting dust storms is a complicated matter. A new study was able to predict storms in our region with a high level of accuracy - and thereby outline how artificial intelligence can be harnessed to understand processes in the atmosphere
This infrared imaging from the Web's near infrared wavelength camera (NIRCam) combines data from two 1.4 and 3.0 micron filters, shown here in blue and orange, respectively. The planet shows a blue tint in the image obtained with a representative color. Image credit: NASA, ESA, CSA, STScI, J. DePasquale (STScI)

Creating acid rain: Acidic gases (sulfur dioxide and nitrogen oxides) are emitted from factories and vehicles into the atmosphere, where they are carried by the wind until they reach clouds or water-rich fog. The gases then dissolve in water and produce acid rain that destroys vegetation and pollutes rivers. And the lakes and crumbled stone buildings.
