In the search for alien life, scientists from Cornell University have suggested that purple may be the new green when it comes to identifying potential biosignatures on exoplanets. Rather than looking for the familiar green hue associated with Earth's plant life, the researchers propose that purple pigments from bacteria using infrared radiation for photosynthesis could serve as a distinctive indicator of life on other worlds. These bacteria, known as purple bacteria, come in a range of colors and could thrive in a variety of conditions, making them strong contenders for dominating different environments. By creating models and databases for signs of life, the study aims to ensure that telescopes can detect life forms that may not resemble those found on Earth. The research opens up the possibility of finding alien life in unique forms and revolutionizing our understanding of life in the universe. The study was supported by grants from the Fulbright Schuman grant, the Brinson Foundation, and the National Science Foundation.

In a recent study, researchers from Utrecht University in the Netherlands provide evidence that Mars may not have been as wet and potentially habitable as previously believed. The study suggests that the gullies on Mars, once thought to be formed by flowing water, could have been created by the sublimation of carbon dioxide (CO2) ice. The team conducted experiments simulating martian conditions, revealing that the CO2 sublimation process can cause sand to become fluidized and mobile, creating flow patterns similar to those seen in martian gullies. Climate modeling also supported this theory, suggesting that the gully activity observed on Mars could be explained by CO2 ice processes. These findings indicate that Mars may have been significantly more arid in its recent past, casting doubt on the possibility of sustained habitable conditions and reducing the likelihood of finding evidence of extraterrestrial life on the planet.
