Milky Way shuts down star formation in neighbouring dwarf galaxies
Milky Way shuts down star formation in neighbouring dwarf galaxies

New radio observations have revealed that within a well-defined boundary around our galaxy, dwarf galaxies are completely devoid of hydrogen gas because of the Milky Way.

Dwarf galaxies dancing around larger ones question universe formation theories

Several dwarf galaxies that `dance` throughout the universe in arranged disc-shaped orbits around larger ones makes it more difficult to understand how the universe was formed and evolved, according to a new study.

Astronomers discover seven new dwarf galaxies

Astronomers in the US have discovered seven new dwarf galaxies using a new `homemade` telescope.

Dwarf galaxies formed large proportion of universe`s stars

Researchers using NASA`s Hubble Space Telescope have claimed that dwarf galaxies are responsible for forming a large proportion of the universe`s stars.

Astrophysicists question map of universe

Astrophysicists have revealed that the accepted model of universe is flawed as the dwarf galaxies that orbit the Milky Way and the Andromeda galaxies does not fit in it.

20-year dark matter mystery `unravelled`

Astronomers believe that they have found the answers to a 20-year debate over how dark matter is distributed in small galaxies.

Modified law of gravity predicts speed of dwarf galaxies

A modified law of gravity was correctly able to predict, before observations were made, the average speed of stars within a galaxy relative to each other in 10 dwarf satellite galaxies of Andromeda.

`Cosmic web stripping` could reveal missing dwarf galaxies

Galaxies and matter in the universe clump in an intricate network of filaments and voids, known as the cosmic web.

Dwarf galaxies may help reveal what `dark matter` really is

Nearly 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies.

Milky Way still feasting on dwarf galaxies

The Sagittarius dwarf galaxy used to be one of the brightest of the Milky Way satellites.
