When an exoplanet is discovered, scientists are quick to describe it and explain its properties. Now, we know of thousands of them, many of which are members of a planetary system, like the well-known TRAPPIST-1 family of ...
Exoplanets have captured the imagination of the public and scientists alike and as the search continues for more, researchers have turned their attention to the evolution of metallicity in the Milky Way. With this answer ...
Thirty years after the discovery of the first exoplanet, astronomers have detected more than 7,000 of them in our galaxy. But there are still billions more to be discovered. At the same time, exoplanetologists have begun ...
Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's responsible for the orbits of the planets and their satellites, but there are other forces that ...
Thousands of mounds and hills in Mars' barren northern plains are full of clay minerals, providing evidence that the rocks here were once soaked with water, a new study reveals. These mounds are all that is left of a landscape, ...
Astrophysicists led by a team from Trinity College Dublin have—for the first time—imaged a large number of exocomet belts around nearby stars, and the tiny pebbles within them. The crystal-clear images show light being emitted ...
Tucked away in a star-forming region in the Taurus constellation, a pair of circling stars are displaying some unexpected differences in the circumstellar disks of dust and gas that surround them. A new study led by researchers ...
New observational data from the James Webb Space Telescope and simulation models have confirmed a new type of planet unlike anything found in the solar system. This provides another piece of the puzzle describing how planets ...
Hot Jupiters are giant planets initially known to orbit alone close to their star. During their migration towards their star, these planets were thought to accrete or eject any other planets present. However, this paradigm ...
We all recognize the importance of sustainable diets for both human and planetary health, yet it often seems like we are up against impossible odds.
