Exploring the low-frequency Universe with the MWA.

Since mid-2013, when the MWA began scanning the Earth’s southern skies, the project has supported a trove of scientific achievements.

MWA’s history includes:

  • detecting the largest known eruption in the Universe since the Big Bang
  • solving the century-old coronal heating problem
  • putting limits on the first-ever fast radio burst with a traceable origin
  • the breakthrough discovery of plasma tube structures in the Earth’s ionosphere
  • involvement in the world’s first detection of gravitational waves and radiation from a neutron star merger
  • the creation of a catalogue of 300,000 galaxies and the first radio-colour panorama of the Universe in the GLEAM all-sky survey, and
  • the discovery of new pulsars and an ultra-long period magnetar
What do we focus on?

Key Areas of Science

Research using the MWA is examining the Universe in more detail than previously possible at low frequencies. Explore our key areas of investigation below.

Epoch of Reionisation

Searching for and studying Cosmic Dawn, when the first stars, galaxies and quasars began forming 13 billion years ago.

Galactic Science

Studies of phenomena in our own Milky Way galaxy, and in distant galaxies.

Time Domain

High-sensitivity surveys of the dynamic radio sky, searching for short-timescale and highly variable phenomena (things that go bump in the night).

Learn More

Space Weather

Investigating our Sun and its effect on near-Earth space weather, with applications such as improving early warnings of solar storms.
