Mid-infrared spectroscopy is one of the few ways to observe the composition of the terrestial planet forming zone, the inner few au, of proto-planetary disks. The species currently detected in […]

Planetary Bodies Observed In Habitable Zone Of Dead Star
A ring of planetary debris studded with moon-sized structures has been observed orbiting close to a white dwarf star, hinting at a nearby planet in the “habitable zone” where water […]

TOI-2285b: A 1.7 Earth-radius Planet Near The Habitable Zone Around A Nearby M Dwarf
We report the discovery of TOI-2285b, a sub-Neptune-sized planet transiting a nearby (42 pc) M dwarf with a period of 27.3 days. We identified the transit signal from the TESS […]

Investigating The Potential For Life Around The Galaxy's Smallest Stars
When the world’s most powerful telescope launches into space this year, scientists will learn whether Earth-sized planets in our ‘solar neighborhood’ have a key prerequisite for life — an atmosphere. […]

Analyzing The Habitable Zones Of Circumbinary Planets Using Machine Learning
Exoplanet detection in the past decade by efforts including NASA’s Kepler and TESS missions has discovered many worlds that differ substantially from planets in our own Solar System, including more […]

Earth-like Biospheres On Other Planets May Be Rare
A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for […]

Oxygen False Positives On Habitable Zone Planets Around Sun-Like Stars
Oxygen is a promising exoplanet biosignature due to the evolutionary advantage conferred by harnessing starlight for photosynthesis, and the apparent low likelihood of maintaining oxygen-rich atmospheres without life.

Circumbinary Habitable Zones In The Presence Of A Giant Planet
Determining habitable zones in binary star systems can be a challenging task due to the combination of perturbed planetary orbits and varying stellar irradiation conditions. The concept of “dynamically informed […]

The Extended Habitable Epoch Of The Universe For Liquids Other Than Water
At high redshifts, the temperature of the cosmic microwave background (CMB) was higher than its value today. We explore the possibility that life may have arisen early because the higher […]
