We report on the tentative detection of trans Ethyl Methyl Ether (tEME), t−CH3CH2OCH3, through the identification of a large number of rotational lines from each one of the spin states of the molecule towards Orion KL.
Habitable Zones & Global Climate
The long-term carbon cycle is vital for maintaining liquid water oceans on rocky planets due to the negative climate feedbacks involved in silicate weathering.
Biosignatures & Paleobiology
We report a detection of water vapor in the protoplanetary disk around DoAr 44 with the Texas Echelon Cross Echelle Spectrograph - a visitor instrument on the Gemini north telescope.
Ancient rocks harbored microbial life deep below the seafloor, reports a team of scientists from the Woods Hole Oceanographic Institution (WHOI), Virginia Tech, and the University of Bremen.
Researchers with the NASA Astrobiology Institute's Virtual Planetary Laboratory Lead Team at the University of Washington have described how mini-Neptune planets could become viable for life around M-Dwarf stars.
Imagine a world without liquid water just solid ice in all directions. It would certainly not be a place that most life forms would like to live.
The ExTrA facility, located at La Silla observatory, will consist of a near-infrared multi-object spectrograph fed by three 60-cm telescopes.
We only have one example of a planet with life: Earth. But within the next generation, it should become possible to detect signs of life on planets orbiting distant stars.
Extremeophiles and Extreme Environments
Bizarre creatures that go years without water. Others that can survive the vacuum of open space.
Toiling in barren rock fields in southern Spain under temperatures as high as 108 degrees Fahrenheit, a team from NASA's Ames Research Center, Honeybee Robotics, and Spain's Centro de Astrobiologia (CAB, INTA-CSIC) is changing dirt into data in a way that could one day be replicated on Mars.
While the Rosetta spacecraft orbits the 67P/Churyumov-Gerasimenko comet, the Philae lander, deployed from Rosetta on November 2014, has gathered data on the surface of the comet that indicate the potential existence of prebiotic organics during the early solar system.
