Earth’s earliest continents may have set the chemical stage for life by regulating boron levels in ancient oceans, a new study in Terra Nova suggests.

JWST Studies The Surface Composition Of Super-Earth LHS 3844 b
Using MIRI (Mid Infrared Instrument) on board the James Webb Space Telescope (JWST), a team of researchers led by former MPIA (Max Planck Institute for Astronomy, Heidelberg, Germany) PhD student […]
New Findings About Exoplanets Challenge Theories Of Planet Formation
Astronomers estimate there is at least one planet for every star in our galaxy. Called exoplanets, they orbit stars outside our solar system. But new research from McMaster University reveals […]
Toward Inferring the Surface Fluxes of Biosignature Gases on Rocky Exoplanets from Telescope Spectra
The James Webb Space Telescope and the future Habitable Worlds Observatory aim to discover exoplanet atmospheric spectra that detect life. Currently, most existing spectral “retrieval” algorithms focus on inferring the […]
Uniform Reinterpretation of Rocky Exoplanet Secondary Eclipse Observations and the Impact of Stellar and Orbital Uncertainties
Secondary eclipse observations are a powerful way to investigate whether or not a rocky exoplanet hosts an atmosphere, as an atmospheric presence would transport heat to the nightside and render […]
Planets Need More Water To Support Life Than Scientists Previously Thought
Unfortunately for science fiction fans, desert worlds outside our solar system are unlikely to host life, according to new research from University of Washington. Scientists show that an Earth-sized planet […]
Determining the Host Stars of Planets in Binary Star Systems with Asterodensity Profiling: Investigating the Canonical Radius Gap
Over the past 30 years, thousands of exoplanets have been discovered, revealing detailed demographics of planets outside the Solar System.
The Role Of Inner Disk Edges In Shaping Ultra-short-period Planet Systems Around Late M Dwarfs
Close-in rocky planets are the most common type of exoplanets around late M dwarfs, ranging from more temperate worlds to highly irradiated lava planets with molten surfaces, and many theoretical […]
Gemini South Confirms Long-Suspected Link Between the Composition of Exoplanets and Their Host Stars
Almost 320 light-years away in the Libra constellation lies WASP-189b, an exoplanet known as an ultra-hot Jupiter (UHJ). UHJs have temperatures high enough to vaporize rock-forming elements like magnesium (Mg), […]
Hot Rocks Survey V: Secondary Eclipse Photometry of GJ 3473 b with JWST/MIRI
JWST is transforming our ability to characterise small exoplanets, from sub-Neptunes to rocky worlds. A key open question is whether highly irradiated rocky planets can retain atmospheres or are stripped […]
