Our Earth, being the only living planet that we know, provides us with clues that photosynthetic life-forms may be dominant on other exoplanets for billions of years.
The James Web Space Telescope’s MIRI instrument, managed by NASA JPL through launch, detected a compact object in the disk of debris surrounding a nearby star.
The Nancy Grace Roman Space Telescope (hereafter, Roman) is NASA’s next astrophysics flagship mission. When fully operational in 2027, Roman will provide the astronomical community with an unparalleled opportunity to […]
Most observed multi-planet systems are coplanar, in a dynamically “cold” configuration of concentric orbits like our own Solar System.
A planetary system described as abnormal, chaotic, and strange by researchers has come into clearer view with NASA’s James Webb Space Telescope. Using Webb’s NIRCam (Near-Infrared Camera), researchers have successfully […]
We present F1550C (15.5 μm) coronagraphic imaging observations of the nearest solar-type star α Cen A using the James Webb Space Telescope (JWST) Mid-InfraRed Instrument (MIRI).
In this paper, we detail recent and current work that is being carried out to fabricate and advance novel SiC UV instrumentation that is aimed at enabling more sensitive measurements […]
![Example of ICA-based background subtraction results for “R05 v2 rez2 snr3 1em10” scenario from the Quartus Engineering analysis. A 2 × 3 set of subplots is shown where rows 1 and 2 correspond to passbands [425- 522] and [615-800] respectively. Columns 1, 2, and 3 of the plot correspond to the original image, the estimated background, and the residual, respectively. -- astro-ph.IM](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/10/Starshade-Exoplanet-Data-Challenge.png?resize=1200%2C719&ssl=1)
Starshade is one of the technologies that will enable the observation and characterization of small planets around nearby stars through direct imaging.
RISTRETTO is the evolution of the original idea of coupling the VLT instruments SPHERE and ESPRESSO lovis_2016a, aiming at High Dispersion Coronagraphy. RISTRETTO is a visitor instrument that should enable […]
The search for biosignatures in potentially habitable exoplanets is one of the major astrophysics’ drivers for the coming decades, and the prime science goal of the HWO NASA mission, a […]
