Reproducing the Building Blocks of Life in Laboratory

Reproducing the Building Blocks of Life in Laboratory

NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory.

Life Not As We Know It Is Possible on Saturn's Moon Titan

Life Not As We Know It Is Possible on Saturn's Moon Titan

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.

Environment Around Black Hole Protects Organic Chemicals

Environment Around Black Hole Protects Organic Chemicals

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.

Complex Organics in the Inner Regions of Solar-type Protostars

Complex Organics in the Inner Regions of Solar-type Protostars

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.

Oxygen Enrichment in Carbon-rich Planetary Nebulae

Oxygen Enrichment in Carbon-rich Planetary Nebulae

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.

Shielding From The Solar Wind: Implications for Habitability

Shielding From The Solar Wind: Implications for Habitability

The onset and nature of the earliest geomagnetic field is important for understanding the evolution of the core, atmosphere and
life on Earth.

Europa

Linking Europa's Plume Activity to Tides, Tectonics, and Liquid Water

Linking Europa's Plume Activity to Tides, Tectonics, and Liquid Water

Much of the geologic activity preserved on Europa's icy surface has been attributed to tidal deformation, mainly due to Europa's eccentric orbit.

Shedding Light on the Formation of the Pre-biotic Molecule Formamide with ASAI

Shedding Light on the Formation of the Pre-biotic Molecule Formamide with ASAI

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.

Collisions of Small ice Particles Under Microgravity Conditions

Collisions of Small ice Particles Under Microgravity Conditions

Understanding the collisional properties of ice is important for understanding both the early stages of planet formation and the evolution of planetary ring systems.

A New Chemical Scheme to Study Carbon-rich Exoplanet Atmospheres

A New Chemical Scheme to Study Carbon-rich Exoplanet Atmospheres

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).

Does Dark Matter Cause Mass Extinctions and Geologic Upheavals?

Does Dark Matter Cause Mass Extinctions and Geologic Upheavals?

Research by New York University Biology Professor Michael Rampino concludes that Earth's infrequent but predictable path around and through our Galaxy's disc may have a direct and significant effect on geological and biological phenomena occurring on Earth.
