The exploration era for the new James Webb Space Telescope (JWST) is getting hot – volcanically hot.
For the first time, astronomers have used NASA’s James Webb Space Telescope (JWST) to take a direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky su...
When it comes to directly imaging Earth-like exoplanets orbiting faraway stars, seeing isn’t always believing.

Scientists have discovered a new exoplanet that, in the language of “Star Wars,” would be the polar opposite of frigid Hoth, and even more inhospitable than the deserts of Tatooine. But instead of res...
Imagine living on an exoplanet with two suns. One, you orbit and the other is a very bright, nearby neighbor looming large in your sky. With this “second sun” in the sky, nightfall might be a rare eve...
The star system harboring the new planet contains only one star, as do the other three systems with extrasolar planets analyzed by Kane, an assistant professor of physics and astronomy, and his collea...

To understand the influence of additional wide stellar companions on planet formation, it is necessary to determine the fraction of multiple stellar systems amongst the known extrasolar planet populat...
A Bayesian Surrogate Model for Rapid Time Series Analysis and Application to Exoplanet Observations
statistics: Bayesian model comparison model selection periodogram numerical methods

We present a Bayesian surrogate model for the analysis of periodic or quasi-periodic time series data. We describe a computationally efficient implementation that enables Bayesian model comparison. We...
Venus transit 2004: Illustrating the capability of exoplanet transmission spectroscopy
Planets and satellites: atmospheres – Planets and satellites: composition – Planets and satellites: detection – Radiative transfer – Techniques: spectroscopic
2011/10/11
The transit of Venus in 2004 offered the rare possibility to remotely sense a well-known planetary atmosphere using ground-based observations for absorption spectroscopy. Transmission spectra of Venus...
The first rocky exoplanet has been discovered by NASA's Kepler space telescope, according to the mission's deputy science team leader Natalie Batalha. The planet is called Kepler-10b and has a density...
