A Tale of Galactic Merger

An international team led by a researcher from Hiroshima University has succeeded in revealing the detailed structure of a massive ionized gas outflow streaming from the starburst galaxy NGC 6240.

ESA's XMM-Newton has found a wind of high-speed gas streaming from the centre of a bright spiral galaxy like our own that may be reducing its ability to produce new stars.

A trio of brightly pulsating stars at the outskirts of the Milky Way is racing away from the galaxy and may confirm a method for detecting dwarf galaxies dominated by dark matter and explain ripples in the outer disk of the galaxy.

Astronomers have used data from three of NASA's Great Observatories to make the most detailed study yet of an extremely massive young galaxy cluster.

Proud parents chart the growth of their children, but astronomers from the Sloan Digital Sky Survey (SDSS) have taken on a bigger task: charting the growth of our own Milky Way.

This NASA/ESA Hubble Space Telescope image shows the spiral galaxy NGC 4845, located over 65 million light-years away in the constellation of Virgo (The Virgin).

Black holes have shown that they too can lose a lot of the weight of the stars that surround them.

VISTA Pinpoints The Earliest Giant Galaxies

Just counting the number of galaxies in a patch of sky provides a way to test astronomers' theories of galaxy formation and evolution.

A Distant Galaxy with a Pulse

Astronomers at Yale and Harvard have found a galaxy with a heartbeat -- and they've taken its pulse.

Using a sample of 4,700 blue horizontal-branch stars from the Sloan Digital Sky Survey, the research team showed that the oldest stars are concentrated in the central region of the galaxy, confirming predictions from numerical simulations of galaxy assembly.

The Vista Variables in the Va Lctea Survey (VVV) ESO public survey is using the VISTA telescope at the Paranal Observatory to take multiple images at different times of the central parts of the galaxy at infrared wavelengths.

A nearby dwarf galaxy poses an intriguing mystery: How is it able to form brilliant star clusters without the dusty, gas-rich environments found in larger galaxies?

Farthest Galaxy Detected

A team of Caltech researchers that has spent years searching for the earliest objects in the universe now reports the detection of what may be the most distant galaxy ever found.

When it comes to our galaxy, home is where the star is.

Astronomers have long known that powerful cosmic winds can sometimes blow through galaxies, sweeping out interstellar material and stopping future star formation. Now they have a clearer snapshot of how it happens.

Astronomers making a detailed, multi-telescope study of a nearby galaxy have discovered a magnetic field coiled around the galaxy's main spiral arm.

Seeing Where Stars Collide

Scientists have imaged a cluster of stars, heavily obscured by material in our galaxy, where stars are so densely packed that it is likely a rare environment where stars can collide.

Astronomers using the several of the largest telescopes on Earth and space have discovered the brightest galaxy yet found in the early Universe and found strong evidence that examples of the first generation of stars lurk within it.

Merging Galaxies Break Radio Silence

In the most extensive survey of its kind ever conducted, a team of scientists have found an unambiguous link between the presence of supermassive black holes that power high-speed, radio-signal-emitting jets and the merger history of their host galaxies.
