MISSE Flight Facility On The International Space Station Tests Organisms, Materials in Space

MISSE Flight Facility On The International Space Station Tests Organisms, Materials in Space

Space may look empty, but it contains extreme temperatures, high levels of background radiation, micrometeoroids, and the unfiltered glare of the Sun.

Origin & Evolution of Life

New Research On The Emergence Of The First Complex Cells Challenges Orthodoxy

New Research On The Emergence Of The First Complex Cells Challenges Orthodoxy

In the beginning, there was boredom. Following the emergence of cellular life on Earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the planet.

Ancient Source Of Oxygen For Life Hidden Deep In The Earth's Crust

Ancient Source Of Oxygen For Life Hidden Deep In The Earth's Crust

Scientists at Newcastle University have uncovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis.

Astrochemical Model to Study the Abundances of Branched Carbon-chain Molecules in a Hot Molecular Core with Realistic Binding Energies

Astrochemical Model to Study the Abundances of Branched Carbon-chain Molecules in a Hot Molecular Core with Realistic Binding Energies

Straight-chain (normal-propyl cyanide, n - C3H7CN) and branched-chain (iso-propyl cyanide, i - C3H7CN) alkyl cyanides are recently identified in the massive star-forming regions (Sgr B2(N) and Orion).

Spectropolarimetry Of Life: Airborne Measurements From A Hot Air Balloon

Spectropolarimetry Of Life: Airborne Measurements From A Hot Air Balloon

Does life exist outside our Solar System? A first step towards searching for life outside our Solar System is detecting life on Earth by using remote sensing applications.

SETI

Drift Rates Of Narrow-band Signals In Long-term SETI Observations for Exoplanets

Drift Rates Of Narrow-band Signals In Long-term SETI Observations for Exoplanets

The Doppler shift of a radio signal is caused by the relative motion between the transmitter and receiver. The change in frequency of the signal over time is called drift rate.

The Effects Of Local Stellar Radiation And Dust Depletion On Non-equilibrium Interstellar Chemistry

The Effects Of Local Stellar Radiation And Dust Depletion On Non-equilibrium Interstellar Chemistry

Interstellar chemistry is important for galaxy formation, as it determines the rate at which gas can cool, and enables us to make predictions for observable spectroscopic lines from ions and molecules.

SETI

Sensitive Multi-beam Targeted SETI Observations Towards 33 Exoplanet Systems With FAST

Sensitive Multi-beam Targeted SETI Observations Towards 33 Exoplanet Systems With FAST

As a major approach to looking for life beyond the Earth, the search for extraterrestrial intelligence (SETI) is committed to detecting technosignatures such as engineered radio signals that are indicative of technologically capable life.

MIRECLE: Science Yield for a Mid-IR Explorer-Class Mission To Study Non-Transiting Rocky Planets Orbiting The Nearest M-Stars Using Planetary Infrared Excess

MIRECLE: Science Yield for a Mid-IR Explorer-Class Mission To Study Non-Transiting Rocky Planets Orbiting The Nearest M-Stars Using Planetary Infrared Excess

Recent investigations have demonstrated the potential for utilizing a new observational and data analysis technique for studying the atmospheres of non-transiting exoplanets with combined light that relies on acquiring simultaneous, broad-wavelength spectra and resolving planetary infrared emission from the stellar spectrum through simultaneous fitting of the stellar and planetary spectral signatures.

Mapping the aliphatic hydrocarbon content of interstellar dust in the Galactic plane

Mapping the aliphatic hydrocarbon content of interstellar dust in the Galactic plane

We implement a new observational method for mapping the aliphatic hydrocarbon content in the solid phase in our Galaxy, based on spectrophotometric imaging of the 3.4 μm absorption feature from interstellar dust.
