VLT Spots Largest Yellow Hypergiant Star

published on 12 March 2014

ESO’s Very Large Telescope Interferometer has revealed the largest yellow star — and one of the ten largest stars found so far. This hypergiant has been found to measure more than 1300 times the diameter of the Sun, and to be part of a double star system, with the second component so close that it is in contact with the main star. Observations spanning over sixty years, some from amateur observers, also indicate that this rare and remarkable object is changing very rapidly and has been caught during a very brief phase of its life.

Dr. Alex Lobel of the ROB is one of the tem members in this project.

Comet C/2012 ISON

published on 25 November 2013

If comet C/2012 S1 (ISON) survives its close pass to the Sun after November 28, it could become a very bright object in the morning skies in the beginning of december.

ISON is named for the Russia-based International Scientific Optical Network, in which the comet's discoverers, Artyom Novichonok and Vitali Nevski, were participating when they observed the comet for the first time in September 2012.

ISON can be seen in SOHO and STEREO images

and our Belgian satellite PROBA2 hopes to see the comet near the sun but had no success.
