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

  • No comments
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.
This artist's impression shows what the distant planet K2-18b, its host star, and another planet in this system might look like. A new analysis from the University of Chicago has cast doubt on a previous finding that concluded the data showed evidence of life on the planet.

Possible signs of life on a distant planet? Not so fast. New research suggests the signal may be ordinary molecules, not alien biology.

Unstable carbon compounds in space? A new discovery may explain the cosmic origins of life 

  • No comments
Researchers at the University of Maryland have developed a new method to produce unstable carbon compounds, specifically hydroxymethylene, using UV rays to break down methanol. This discovery not only explains the formation of carbon compounds on the surface of a sphere
Astronomers have found water vapor in the disk around a young star right where planets are likely to form. In this image, the new observations from the ESO partner Atacama Large Millimeter/Submillimeter Array (ALMA) show the water vapor in shades of blue. Near the center of the disc, where the young star lives, the environment is hotter and the gas is brighter. The red rings are previous ALMA observations showing the distribution of dust around the star.Credit: ALMA (ESO/NAOJ/NRAO)/S. Facchini et al.

The simulation aims to highlight the temperature differences that researchers hypothesize exist between the discovered planets. The inner two are too close and therefore would be too hot for liquid water, the middle three are in the sitting area where liquid water might be possible, while the outer two are too far away, and apparently, if there is water in them, they are frozen.

Simulation of the lander. According to the proposal, the lander will be launched between 2024-2025 and will arrive several years after the arrival of the EMFM probe, which will make many flybys near Europe. It will be able to photograph it at a very high resolution to find safe but scientifically interesting landing sites, and roly noses like the one described in the simulation - near plumes of water coming out as geysers from the moon Atal past Hal, and it is estimated that, if they do exist in Europe, they originate in its sub-ice ocean.
