Simulations of the formation of the solar system have been largely successful. They are able to replicate the positions of all the major planets along with their orbital parameters. But current simulations have an extreme ...
With simulations that go into finer details than ever before, Brooke Polak of the University of Heidelberg and Hubert Klahr at the Max Planck Institute for Astronomy (MPIA) have modeled a key phase in the formation of planets ...
A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of exoplanets a few times more massive than Earth that are the most abundant type of planet in the galaxy.
NASA's James Webb Space Telescope has imaged the inner workings of a dusty disk surrounding a nearby red dwarf star. These observations represent the first time the previously known disk has been imaged at these infrared ...
The origin of Earth's water has been an enduring mystery. There are different hypotheses and theories explaining how the water got here, and lots of evidence supporting them.
The moon's pock-marked surface tells the story of its history. It's marked by over 9,000 impact craters, according to the International Astronomical Union (IAU.) The largest ones are called impact basins, not craters. Now, ...
According to the most widely-accepted theory, planetary systems form from large clouds of dust and gas that form disks around young stars. Over time, these disks accrete to create planets of varying size, composition, and ...
What will happen to our sun?
Astronomers led by the University of Warwick have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the ...
Bulgarian astronomers have performed long-term optical photometric observations of a young variable star known as V1180 Cas. Results of the observational campaign deliver essential information about the variability of V1180 ...
