SETI
The Breakthrough Listen Search for Extraterrestrial Intelligence 
The discovery of the ubiquity of habitable extrasolar planets, combined with revolutionary advances in instrumentation and observational capabilities, have ushered in a renaissance in the millenia-old quest to answer our most profound question about the Universe and our place within it - Are we alone?
Moon
Searching the Moon for Extrasolar Material and the Building Blocks of Extraterrestrial Life
Due to its absence of an atmosphere and relative geological inertness, the Moon's surface records past impacts of objects from the Solar system and beyond.
Planetary Protection
Absolute Prioritization of Planetary Protection, Safety, and Avoiding Imperialism in All Future Science Missions: A Policy Perspective
The prioritization and improvement of ethics, planetary protection, and safety standards in the astro-sciences is the most critical priority as our scientific and exploratory capabilities progress, both within government agencies and the private sector.
SETI
SETI in the Spatio-Temporal Survey Domain
Traditional searches for extraterrestrial intelligence (SETI) or "technosignatures" focus on dedicated observations of single stars or regions in the sky to detect excess or transient emission from intelligent sources.
Biosignatures & Paleobiology
Expanding the Timeline for Earth's Photosynthetic Red Edge Biosignature
When Carl Sagan observed the Earth during a Gallileo fly-by in 1993, he found a widely distributed surface pigment with a sharp reflection edge in the red part of the spectrum, which, together with the abundance of gaseous oxygen and methane in extreme thermodynamic disequilibrium, were strongly suggestive of the presence of life on Earth.
SETI
Searching for Extraterrestrial Intelligence by Locating Potential ET Communication Networks in Space
There have been periodic efforts in recent decades to search for extraterrestrial intelligence (SETI), especially by trying to find an extraterrestrial (ET) radio signal or other technosignature in space. Yet, no such technosignatures have been found.
Titan
'Titan in a Jar' Could Answer Questions Ahead of Dragonfly
Researchers from Southern Methodist University (SMU) could help determine if Saturn's icy moon -- Titan -- has ever been home to life long before NASA completes an exploratory visit to its surface by a drone helicopter.
Mars
New Mechanism For Methane Vanishing On Mars
The processes behind the release and consumption of methane on Mars have been discussed since methane was measured for the first time for approx. 15 years ago.
Oceanic Research
Illuminating The Smallest Inhabitants of the Largest Ocean Desert
The middle of the South Pacific is as far away from land as you can possibly get. Solar irradiance is dangerously high, reaching a UV-index that is labelled 'extreme'.
Habitable Zones & Global Climate
Runaway Climate Cooling Of Ocean Planets In The Habitable Zone
Terrestrial planets covered globally with thick oceans (termed ocean planets) in the habitable zone were previously inferred to have extremely hot climates in most cases.
Analog Studies
Santorini Volcano, A New Terrestrial Analog of Mars
One of the great attractions of the island of Santorini, in Greece, lies in its spectacular volcanic landscape, which also contains places similar to those of Mars. A team of European and U.S. scientists has discovered it after analysing basaltic rocks collected in one of its coves.
