A new model that accounts for the interplay of forces acting on newborn planets can explain two puzzling observations that have cropped up repeatedly among the more than 3,800 planetary systems cataloged to date.
One puzzle known as the "radius valley" refers to the rarity of exoplanets with a radius about 1.8 times that of Earth.
Planets Make it Harder to Figure out a Star's age - Universe Today
Estimating stellar age has always been a challenge for astronomers. Now, a certain class of exoplanets is making the process even more complicated.
Determining a star's age is hard enough on its own without taking into account planetary interference.
Things get more complicated if you want to know the age of an individual star. We do know that young stars rotate quickly, and slow down as they age.
Atmosphere of excitement as Europe's JWST astronomers study climate on other planets
"Before the James Webb Space Telescope, only a very small number of molecules could be observed, such as water, carbon monoxide and sodium," said Jérémy Leconte, astrophysicist at the University of Bordeaux in France.
Earlier this year, the James Webb telescope allowed astrophysicists to observe an exoplanet around a sun-like star, 700 light-years away. Starlight passing through the atmosphere of the hot Jupiter-like planet WASP-39b gives astronomers a view into the chemistry of alien skies.

Thousands of planets have been found in other star systems. They're all so far away, though, that most are no more than squiggly lines on a computer screen. Yet scientists are slowly teasing the details out of the squiggles.
To understand how difficult the problem is, consider that there's still a lot to learn about the planets of our own solar system.

James Webb Space Telescope could help hunt for habitable planets | Space
TRAPPIST-1e is one of seven worlds in the Trappist-1 system orbiting a relatively cool M-dwarf star located 39 light-years from Earth.
Over the coming year, the system and TRAPPIST-1e — considered one of the most 'potentially habitable' exoplanets ever discovered — in particular, will be the subject of intense study by the James Webb Space Telescope (JWST).
Scientists Discover New Class Of Exoplanet - WorldAtlas
Since the discovery of the first exoplanet in 1995, scientists have confirmed the existence of over 5,200 exoplanets.
To determine the composition of some exoplanets around red dwarfs, scientists examined some of the closest red dwarfs and their planets. The closer the star, the easier it is to detect and study any orbiting planets.
What happens to hot Jupiters when their star becomes a red giant?
The research was led by Mike Lau, a Ph.D. student at Monash University's School of Physics & Astronomy, and other members of the COMPAS consortium, a collaborative effort to study the evolution of binary systems.
"This is, therefore, one way of explaining observed rapidly rotating giant stars. Also, any planetary material that comes off during the in-spiral could alter stars' surface chemical makeup. This may help us understand why a small fraction of stars are observed to be abnormally rich in lithium.
The State News daily horoscope for Tuesday, Nov. 8: Vote - The State News
For the first time since 1875 when the day was established by Congress, there is going to be a lunar eclipse on Election Day.
A lunar eclipse occurs when the moon, Earth and sun align. According to MSU's Abrams Planetarium production coordinator, the Earth blocks the moon from the sun's rays, casting a shadow and darkening the moon.
