The supernova that wasn’t: a tale of three cosmic eruptions

4 September 2016 Astronomy Now

Combining images taken with the NASA/ESA Hubble Space Telescope over more than 20 years, a team of researchers has discovered that Eta Carinae, a very massive star system that has puzzled astronomers since it erupted in a supernova-like event in the mid-19th century, has a past that’s much more violent than they thought.

Mysterious ripples found racing through planet-forming disc

7 October 2015 Astronomy Now

Astronomers using NASA’s Hubble Space Telescope and ESO’s Very Large Telescope in Chile have discovered never-before-seen moving features within the dusty disc surrounding the young, nearby star AU Microscopii. The fast-moving, wave-like structures are moving at 22,000 miles per hour — fast enough to escape the star’s gravitational pull.

Construction to begin on world’s largest optical telescope

3 June 2015 Astronomy Now

Collaborators secure more than $500 million for the historic $1 billion project to build the Giant Magellan Telescope — a seven-mirror colossus gathering more than six times the amount of light of the current largest optical telescopes into images up to 10 times sharper than those of the Hubble Space Telescope.

Lava lake of Io’s volcano Loki viewed with Large Binocular Telescope

30 April 2015 Astronomy Now

With the first detailed observations through imaging interferometry of a lava lake on Io, Jupiter’s innermost Galilean moon, the Large Binocular Telescope Observatory places itself as the forerunner of the next generation of extremely large telescopes.

Universe expanding more slowly than previously thought?

13 April 2015 Astronomy Now

A University of Arizona-led team of astronomers found that the type of supernovae commonly used to measure distances in the universe fall into distinct populations not recognised before. The findings have implications for our understanding of how fast the universe has been expanding since the Big Bang.

Space observatories find missing clue to galaxy cluster formation

2 April 2015 Astronomy Now

Astronomers using the Herschel Space Observatory and Plank satellite, plus University of Arizona observatories, discover likely precursors of the galaxy clusters we see today and reveal glimpses into how galaxies like our Milky Way came to be.
