A primitive ocean on Mars once held more water than Earth's Arctic Ocean, according to NASA scientists who measured signatures of water in the planet's atmosphere using the most powerful telescopes on Earth including the W. M. Keck Observatory on Hawaii.
NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory.
A new type of methane-based, oxygen-free life form that can metabolize and reproduce similar to life on Earth has been modeled by a team of Cornell University researchers.
A research team led by Shuro Takano at NAOJ and Taku Nakajima at Nagoya University observed the spiral galaxy M77 with ALMA and discovered that organic molecules are concentrated in a region surrounding a supermassive black hole at its center.
The high abundances of Complex Organic Molecules (COMs) with respect to methanol, the most abundant COM, detected towards low-mass protostars, tend to be underpredicted by astrochemical models.
We studied the relation between the chemical composition and the type of dust present in a group of 20 Galactic planetary nebulae (PNe) that have high quality optical and infrared spectra.
The onset and nature of the earliest geomagnetic field is important for understanding the evolution of the core, atmosphere and
life on Earth.
Much of the geologic activity preserved on Europa's icy surface has been attributed to tidal deformation, mainly due to Europa's eccentric orbit.
Formamide (NH2CHO) has been proposed as a pre-biotic precursor with a key role in the emergence of life on Earth. While this molecule has been observed in space, most of its detections correspond to high-mass star-forming regions.
Understanding the collisional properties of ice is important for understanding both the early stages of planet formation and the evolution of planetary ring systems.
Atmospheres with a high C/O ratio are expected to contain an important quantity of hydrocarbons, including heavy molecules (with more than 2 carbon atoms).
