Biosignatures & Paleobiology
It may seem like magic, but astronomers have worked out a scheme that will allow them to detect and measure particles ten times smaller than the width of a human hair, even at many light-years distance.
We address disequilibrum abundances of some simple molecules in the atmospheres of solar composition brown dwarfs and self-luminous extrasolar giant planets using a kinetics-based 1D atmospheric chemistry model.
We present spectrally and spatially-resolved maps of HNC and HC3N emission from Titan's atmosphere, obtained with the Atacama Large Millimeter Array (ALMA) on 2013 November 17.
Habitable Zones & Global Climate
The diversity and quantity of moons in the Solar System suggest a manifold population of natural satellites exist around extrasolar planets.
Observations were made for a number of carbon-rich circumstellar envelopes using the Phoenix spectrograph on the Gemini South telescope to determine the abundance of small carbon chain molecules.
Interstellar molecules with a peptide link -NH-C(=O)-, like formamide (NH2 CHO), acetamide (NH2 COCH3) and isocyanic acid (HNCO) are particularly interesting for their potential role in pre-biotic chemistry.
We present a deep near-infrared image of the newly discovered brown dwarf WISE J085510.83-071442.5 (W0855) using the FourStar imager at Las Campanas Observatory.
Recently, the Kepler Space Telescope has detected several planets in orbit around a close binary star system.
Extremeophiles and Extreme Environments
Researchers this week published a paper confirming that the waters and sediments of a lake that lies 800 meters (2,600 feet) beneath the surface of the West Antarctic ice sheet support "viable microbial ecosystems."
According to new research humble, microscopic organisms can create dripstones in caves. This illustrates how biological life can influence the formation of Earth's geology - and the same may be happening right now on other planets in space.
One of the most bizarre-looking fossils ever found - a worm-like creature with legs, spikes and a head difficult to distinguish from its tail - has found its place in the evolutionary Tree of Life, definitively linking it with a group of modern animals for the first time.
