Eta Carina (aka "ate a car") is arguably the greatest intergalactic threat to life Earth, considering that it could already be responsible for known solar phenomena in our sun (including possibly the 11/5.5 year) cycle going back billions of years, and it has a mysterious connection to our sun. It is fairly close to us in cosmological terms.
Here is the most recent story. In the past, Eta Car has been the brightest star in the night sky (in the Southern hemisphere) and may become so, once again. It is a binary, and one of the two could be a quark star. http://www.csmonitor.com/Science/2015/0108/NASA-unravels-mysteries-of-huge-s pace-explosion About three years ago this came up again on Vortex in this thread https://www.mail-archive.com/vortex-l%40eskimo.com/msg63181.html And this is not the first time we have given notice to the "death star". It has a long ominous history, even on vortex. Curiously - the last poster in the thread above seems to think that there could be Rossi connection.
