Unveiling the turbulent times of a dying star

1 December 2015 Astronomy Now

Astrophysicists have used the National Science Foundation’s Blue Waters supercomputer to perform 3-D simulations of a mere 10 milliseconds in the collapse of a massive star into a neutron star, proving that these catastrophic events — often called hypernovae — can generate the enormous magnetic fields needed to explode the star and fire off bursts of gamma rays visible halfway across the universe.


Hubble reveals galaxy gas flow and star birth regulated by black-hole jets

10 August 2015 Astronomy Now

Astronomers have uncovered a unique process for how the universe’s largest elliptical galaxies continue making stars long after their peak years of star birth. NASA’s Hubble Space Telescope revealed brilliant knots and chains of hot, blue stars forming along the jets of active black holes found in the centres of giant elliptical galaxies.


Newly dedicated observatory to search for gravitational waves

20 May 2015 Astronomy Now

Seeking to expand how we observe and understand phenomena such as supernovae and colliding black holes that generate gravitational waves, the National Science Foundation has just dedicated the Advanced Laser Gravitational Wave Observatories (Advanced LIGO) in Richland, Washington and Livingston, Louisiana.
