Here are a few ways mountains contribute to the Earth's landscape: 1. Tectonic Activity: Mountains are often  While mountains are crucial to the Earth's geological and biological systems, the Earth's "form" is determined by a combination of various factor...

Astronomers investigate extreme variability of the 'Big Dipper' active galactic nucleus

Astronomers have carried out an observational campaign to study the extreme variability of the active galactic nucleus (AGN) SDSS J2232−0806, nicknamed the Big Dipper. Results of these observations, described in a paper published February 18 on the arXiv pre-print server, shed some new light on the nature of this variability.
