Genome Sequence Of Chlamydomonas reinhardtii Submitted To NASA Genelab Data Repository

Genome Sequence Of Chlamydomonas reinhardtii Submitted To NASA Genelab Data Repository

Chlamydomonas reinhardtii is the first single-cell green algae data to be submitted to NASA GeneLab's Data Repository. Microalgae such as this convert light, water, & carbon dioxide into biomass under artificial light conditions, a necessity for space photosynthetic production.

Breakthrough Listen Releases 2 Petabyes of Data From A SETI Survey Of The Milky Way

Breakthrough Listen Releases 2 Petabyes of Data From A SETI Survey Of The Milky Way

The Breakthrough Listen Initiative today (Friday, Feb. 14) released data from the most comprehensive survey yet of radio emissions from the plane of the Milky Way galaxy and the region around its central black hole, and it is inviting the public to search the data for signals from intelligent civilizations.

Irradiated Ocean Planets Bridge Super-Earth And Sub-Neptune Populations

Irradiated Ocean Planets Bridge Super-Earth And Sub-Neptune Populations

With radii ranging between those of the Earth (1 Rearth) and Neptune (~3.9 Rearth), small planets constitute more than half of the inventory of the 4000-plus exoplanets discovered so far.

Dust Devils On Titan

Dust Devils On Titan

Conditions on Saturn's moon Titan suggest dust devils, which are convective, dust-laden plumes, may be active.

On Carbon Nanotubes In The Interstellar Medium

On Carbon Nanotubes In The Interstellar Medium

Since their discovery in 1991, carbon nanotubes (CNTs) -- a novel one-dimensional carbon allotrope -- have attracted considerable interest worldwide because of their potential technological applications such as electric and optical devices.

A Mid-infrared Interferometric Survey Of The Planet-forming Region Around Young Sun-like Stars

A Mid-infrared Interferometric Survey Of The Planet-forming Region Around Young Sun-like Stars

We present our results from a mid-infrared interferometric survey targeted at the planet-forming region in the circumstellar disks around low- and intermediate-mass young stars.

The TRAPPIST-1 JWST Community Initiative

The TRAPPIST-1 JWST Community Initiative

The upcoming launch of the James Webb Space Telescope (JWST) combined with the unique features of the TRAPPIST-1 planetary system should enable the young field of exoplanetology to enter into the realm of temperate Earth-sized worlds.

Salt Water May Periodically Form on the Surface of Mars

Salt Water May Periodically Form on the Surface of Mars

Briny water may form on the surface of Mars a few days per year, research by Planetary Science Institute Senior Scientist Norbert Schorghofer shows.

Aliphatic Hydrocarbon Content Of The Interstellar Dust

Aliphatic Hydrocarbon Content Of The Interstellar Dust

In the interstellar medium, carbon is distributed between the gas and solid phases. However, while about half of the expected carbon abundance can be accounted for in the gas phase, there is considerable uncertainty as to the amount incorporated in interstellar dust.

Titan

Experimental Study Of Ethylene Evaporites Under Titan Conditions

Experimental Study Of Ethylene Evaporites Under Titan Conditions

Titan has an abundance of lakes and seas, as confirmed by Cassini. Major components of these liquid bodies include methane (CH4) and ethane (C2H6); however, evidence indicates that minor components such as ethylene (C2H4) may also exist in the lakes.
