Canadian Astronomical Society Annual Meeting May 28-30, Vancouver, BC Fabio Antonini of the Canadian Institute for Theoretical Astrophysics and David Merritt of the Rochester Institute of Technology have developed a new theory that explains the orbits of the massive young stars that closely orbit the black hole at the centre of the Milky Way.

The discovery of these stars called “S-stars”…

How to Build a Really Big Star


Dr. Alana Rivera-Ingraham explains how massive stars form in a study published in April’s issue of The Astrophysical Journal. “This observation may lift the veil on the formation of the most massive stars which remains, so far, poorly understood,” says Rivera-Ingraham, who led the study while she was a graduate student at U of T under Peter Martin at CITA. Rivera-Ingraham is now a…

PLANCK reveals the Universe’s First Light


The best map ever made of the most ancient light in the universe — the remnant radiation left over from the Big Bang some 13 billion years ago — clarifies our understanding of the universe. The highly detailed image of the universe — produced by the European Space Agency’s Planck Space Telescope and the Planck collaboration of international scientists including a team from U of T —…

PLANCK ALERT: The Veils Come Off March 21st

The first cosmology data release from the Planck mission will take place March 21, 2013 in Paris, at 10 AM CET (4 AM EST).

The Planck results presented will include the world’s highest resolution all-sky map showing the detailed patterns in the remnant radiation left over from the Big Bang some 13 billion years ago. To create the map, the Planck scientists removed the bright foreground…

Outreach – Dr. Linda Strubbe leads the Nigeria Short Course in Astronomy

Outreach: Dr. Linda Strubbe leads the Nigeria Short Course in Astronomy

In October, 2013, CITA post-doctoral fellow Dr. Linda Strubbe led a team of three graduate students from the Department of Astronomy and Astrophysics to teach a five-day short course in Astronomy.  The course was the culmination of 10 months of intense preparation and more than a year of planning, and was attended…
