Much of the progress in Astronomy has been driven by instrumental developments, from the first telescopes to fiber fed spectrographs.


ALMA Resolves Gas Impacted By Young Jets From Supermassive Black Hole

ALMA Resolves Gas Impacted By Young Jets From Supermassive Black Hole

Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA).


Star Formation Project Maps Nearby Interstellar Clouds

Star Formation Project Maps Nearby Interstellar Clouds

Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation. The results of this survey, called the Star Formation Project, will help improve our understanding of the star formation process.

This image taken by the NASA/ESA Hubble Space Telescope shows the galaxy NGC 4237. Located about 60 million light-years from Earth in the constellation of Coma Berenices (Berenice's Hair)


Quasar Tsunamis Rip Across Galaxies

Quasar Tsunamis Rip Across Galaxies

Using the unique capabilities of NASA's Hubble Space Telescope, a team of astronomers has discovered the most energetic outflows ever witnessed in the universe. They emanate from quasars and tear across interstellar space like tsunamis, wreaking havoc on the galaxies in which the quasars live.
