Is this how you get hot Jupiters?
When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar with in our solar system......»»
Astronomers spot a "highly eccentric" planet on its way to becoming a hot Jupiter
Hot Jupiters are some of the most extreme planets in the galaxy. These scorching worlds are as massive as Jupiter, and they swing wildly close to their star, whirling around in a few days compared to our own gas giant's leisurely 4,000-day orbit arou.....»»
This hot Jupiter is doomed to crash into its star in just three million years
In 2008, astronomers with the SuperWASP survey spotted WASP-12b as it transited in front of its star. At the time, it was part of a new class of exoplanets ("hot Jupiters") discovered a little more than a decade before. However, subsequent observatio.....»»
TESS discovers nine new "hot Jupiters"
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered nine new "hot Jupiter" exoplanets. One of the newly detected alien worlds is almost four times more massive than Jupiter. The finding was p.....»»
A 14-inch spacecraft delivers new details about "hot Jupiters"
A spacecraft the size of a cereal box has collected precise measurements of the atmospheres of large and puffy planets called "hot Jupiters." The findings, led by a team from the University of Colorado Boulder, could help reveal how the atmospheres a.....»»
Astronomers discover two "hot Jupiters" orbiting red-giant stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two new "hot Jupiter" exoplanets. The newfound alien worlds, designated TOI-4377 b and TOI-4551 b, both orbit distant red-giant stars. The.....»»
Old stars don"t have hot Jupiters, suggests study
As we began to discover hundreds, then thousands of exoplanets, we found that there were two types of worlds unlike anything in our solar system. The first are super-Earths. These worlds straddle the line between large rocky worlds like Earth and sma.....»»
A "Jupiter" hotter than the sun
The search for exoplanets—planets that orbit stars located beyond the borders of our solar system—is a hot topic in astrophysics. Of the various types of exoplanets, one is hot in the literal sense: hot Jupiters, a class of exoplanets that are ph.....»»
The case of the missing Jupiters: Gas giant planets are a no-show around small red stars
Astronomers have revealed that the smallest and most common kinds of stars in the universe, called red dwarfs, very rarely host big, Jupiter-like planets. This absence of Jupiter analogs could have major impacts on the development of Earth-like plane.....»»
Trading spaces: How swapping stars create hot Jupiters
Star clusters tend to host more hot Jupiters than average, but why? A team of astronomers have proposed a new solution, and it involves a lot of swapping of stellar neighbors......»»
New clues about how hot Jupiters form
Since the first hot Jupiter was discovered in 1995, astronomers have been trying to figure out how the searing-hot exoplanets formed and arrived in their extreme orbits. Johns Hopkins University astronomers have found a way to determine the relative.....»»
Hubble spies on 25 hot Jupiters to learn about their atmospheres
The Hubble Space Telescope have investigated 25 exoplanets to find out about how the composition of their atmospheres......»»
This extreme exoplanet’s atmosphere is being sunburned by its host star
Some of the most extreme exoplanets we've found are a type called hot Jupiters, where high temperatures lead to some weird and wonderful effects......»»
Hubble probes extreme weather on ultra-hot Jupiters
In studying a unique class of ultra-hot exoplanets, NASA Hubble Space Telescope astronomers may be in the mood for dancing to the Calypso party song "Hot, Hot, Hot." That's because these bloated Jupiter-sized worlds are so precariously close to their.....»»
Weird weather: Metal rain and super-high temperatures on an ultra-hot exoplanet
Ultra-hot Jupiters—named as such because of their physical similarities to the planet Jupiter—are exoplanets that orbit stars other than the sun with temperatures so high that the molecules in their atmospheres are completely torn apart. They are.....»»
Astronomers provide "field guide" to exoplanets known as hot Jupiters
Hot Jupiters—giant gas planets that race around their host stars in extremely tight orbits—have become a little bit less mysterious thanks to a new study combining theoretical modeling with observations by the Hubble Space Telescope......»»
Astronomers discover four new "hot Jupiters"
An international team of astronomers has detected four new "hot Jupiter" exoplanets as part of the Next Generation Transit Survey (NGTS). The newly found alien worlds are at least 10% larger than Jupiter but less massive than the solar system's bigge.....»»
NASA"s Roman mission will probe galaxy"s core for hot Jupiters, brown dwarfs
When it launches in the mid-2020s, NASA's Nancy Grace Roman Space Telescope will explore an expansive range of infrared astrophysics topics. One eagerly anticipated survey will use a gravitational effect called microlensing to reveal thousands of wor.....»»
