Testing Underground To Learn How To Find Life On Mars

Testing Underground To Learn How To Find Life On Mars

If life exists on Mars, it will have sought refuge underground. Trying to uncover one of the best-kept secrets in the Solar System, scientists are working a kilometre beneath the ground, with ESA astronaut Matthias Maurer joining them this week.

Study Shows How Water Could Have Flowed on 'Cold and Icy' Ancient Mars

Study Shows How Water Could Have Flowed on 'Cold and Icy' Ancient Mars

For scientists trying to understand what ancient Mars might have been like, the red planet sends some mixed signals. Water-carved valleys and lakebeds leave little doubt that water once flowed on the surface.

Astrochemistry: Overview and Challenges

Astrochemistry: Overview and Challenges

This paper provides a brief overview of the journey of molecules through the Cosmos, from local diffuse interstellar clouds and PDRs to distant galaxies, and from cold dark clouds to hot star-forming cores, protoplanetary disks, planetesimals and exoplanets.

Direct Measurement of Interparticle Forces of Titan Aerosol Analogs ("Tholin") Using Atomic Force Microscopy

To understand the origin of the dunes on Titan, it is important to investigate the material properties of Titan's organic sand particles on Titan.

Mapping Vinyl Cyanide and Other Nitriles in Titan's Atmosphere Using ALMA

Mapping Vinyl Cyanide and Other Nitriles in Titan's Atmosphere Using ALMA

Vinyl cyanide (C2H3CN) is theorized to form in Titan's atmosphere via high-altitude photochemistry and is of interest regarding the astrobiology of cold planetary surfaces due to its predicted ability to form cell membrane-like structures (azotosomes) in liquid methane.

Assessing the Interior Structure of Terrestrial Exoplanets with Implications for Habitability

Assessing the Interior Structure of Terrestrial Exoplanets with Implications for Habitability

Astrophysical observations reveal a large diversity of radii and masses of exoplanets. It is important to characterize the interiors of exoplanets to understand planetary diversity and further determine how unique, or not, Earth is.

OSIRIS-REx Vegetation Index of Earth with MapCam Color Image Overlaid

OSIRIS-REx Vegetation Index of Earth with MapCam Color Image Overlaid

This vegetation index, created using images taken by OSIRIS-REx's MapCam camera on Sept. 22, 2017, shows areas on Earth with abundant plant life.

Planetary Formation and Water Delivery in the Habitable Zone Around Solar-type Stars in Different Dynamical Environments

Planetary Formation and Water Delivery in the Habitable Zone Around Solar-type Stars in Different Dynamical Environments

Aims. We study the formation and water delivery of planets in the habitable zone (HZ) around solar-type stars. In particular, we study different dynamical environments that are defined by the most massive body in the system.

Circulation Regimes of Synchronously Rotating Terrestrial Planets Near The Inner Edge of the Habitable Zone

Circulation Regimes of Synchronously Rotating Terrestrial Planets Near The Inner Edge of the Habitable Zone

We investigate the atmospheric dynamics of terrestrial planets in synchronous rotation near the inner edge of the habitable zone of low-mass stars using the Community Atmosphere Model (CAM).
