The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports. The team has shown ...

Galaxies are vast gravitational structures that harbor billions to trillions of stars, as well as, interstellar gas, dust, and nebulae as well as the dark matter that binds them together. Our solar ...

A team of Japanese astronomers from the National Astronomical Observatory of Japan, Tokyo University, and Kyoto University in Japan obtained infrared and high-resolution images of galaxies from 11 ...

Early-type galaxies, encompassing both elliptical and lenticular systems, are characterised by smooth stellar light distributions and a predominance of random over ordered motions. Stellar kinematics ...

Galaxies like our Milky Way grew through cascading mergers of smaller galaxies that began billions of years ago. The ancient progenitors of galaxies like ours were small galaxies similar to modern-day ...

Astronomers have spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the ...

Early-type galaxies, encompassing ellipticals and lenticulars, are characterised by smooth stellar light distributions, predominantly old and metal-rich stellar populations, and negligible ongoing ...

Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn't sit well with ...

The vastness of space allows for a huge variety of structures to pop up all over the place. Even things we think of as one-and-done objects—like galaxies—come in quite a few shapes and sizes. Follow ...
