We present detailed asteroseismic modelling of 95 main-sequence solar-like stars and Kepler exoplanet host stars using the FICO procedure, a three-step method that combines forward and inverse techniques that enables […]
Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system. But new […]
The European Space Agency Plato mission has successfully completed a series of tough tests under space‑like conditions. With this accomplishment, the spacecraft is on track to lift off in early […]
A new study of infant stars in the Perseus and Orion star-forming regions suggests that most close pairs of stars are born as twins in the same disk, rather than […]
Context. The development of refined instruments and techniques for a detailed analysis of the radial velocities (RVs) of stars other than the Sun allows the presence of planetary signals of […]
Astronomers at the University of Warwick have validated over 100 exoplanets, including 31 newly detected planets, using a new artificial intelligence tool applied to data from NASA’s Transiting Exoplanet Survey […]
Earth’s climate is influenced by over a dozen types of feedback, but only three dominate its long-term climate behavior. Models of the exoplanet habitable zone (HZ) assume that this is […]
![Overview of the L1544 (LEFT panel) and IRAS 16293–2422 (RIGHT panel) regions as traced by the Herschel3 continuum maps at 350 𝜇m. The white contours correspond to [5,7,9,12,14]𝜎, where 𝜎 is 12 MJy sr−1 in L1544, and 1.1 MJy sr−1 in IRAS 16293–2422, respectively. The FoVs of the GBT observations are shown as blue circles – solid line for Ku-band and dashed line for X-band observations (see Sect. 3). Green diamonds identify the continuum (∼1.3 mm) peak position in L1544 (Ward-Thompson et al. 1999) and the position of the A/B, and E objects in IRAS 16293–2422 (Kahle et al. 2023). The size of the Herschel beam (25′′) is shown in the bottom left corner, while the scale bar is shown in the bottom right. -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/02/Carbon-chain-diversity.png?resize=1200%2C716&ssl=1)
Astrochemical observations have revealed a surprisingly high level of chemical complexity, including long carbon chains, in the earliest stages of Sun-like star formation.
As the only known habitable (and inhabited) planet in the universe, Earth informs our search for life elsewhere. Future telescopes like the Habitable Worlds Observatory (HWO) will soon look for […]
The Discovery A candidate planet that might be remarkably similar to Earth, HD 137010 b, has one potentially big difference: It could be colder than perpetually frozen Mars. See A […]
