A new analytical transmission model incorporating pressure-dependent opacity improves interpretation of exoplanet atmospheres and supports data analysis from JWST and the upcoming ARIEL mission.

Since the transit method relies on direct line of sight to our planet, and exoplanets orbit with random orientations, how many exoplanets are estimated to be uncounted using this method? This is a ...

Scientists have discovered over 6,000 planets that orbit stars other than our sun, known as exoplanets. More than half of these planets were discovered thanks to data from NASA's retired Kepler ...

Exoplanet science has entered an exciting new phase with the development of the EXCITE mission, a groundbreaking project designed to enhance our understanding of exoplanet atmospheres. Unlike ...

On Aug. 24, 2023, more than three decades after the first confirmation of planets beyond our own solar system, scientists announced the discovery of six new exoplanets, stretching that number to 5,502 ...

A purely hypothetical field a few decades ago, exoplanet hunters inhabit one of the most dynamic areas in astronomy today. Each discovery brings new insights. From giant gas planets to so-called super ...

We are entering a new period of exoplanet astronomy, with a recent announcement that the James Webb Space Telescope has detected its first exoplanet. The promise of Webb is that it will be able to not ...

Our solar system hosts almost 900 known moons; more than 400 orbit the eight planets while the remaining orbit dwarf planets, ...

Of all the big, ambitious goals in astronomy right now, one of the most exciting is the discovery and characterization of exoplanets, or planets outside our solar system. We know that there are likely ...

The measured transit spectrum (top) and eclipse spectrum (bottom) of WASP-80 b from NIRCam’s slitless spectroscopy mode on NASA’s James Webb Space Telescope. In both spectra, there is clear evidence ...

Scientists using NASA's Transiting Exoplanet Survey Satellite (TESS) discovered an exoplanet, which NASA defines as “any planet beyond our solar system.” What's False However, the “strange signals” ...

An exoplanet is a planet from a different star system. Most known exoplanets orbit stars within the Milky Way, but with the help of powerful space telescopes, scientists have discovered exoplanets far ...
