D) Aquarius
Correct Answer: A
Solution :
[a] In 2013 an Indian scientist (Ananda Hota) and his Taiwanese colleague (Dr. Youichi Ohyama) have discovered a blue super-giant star located in the constellation Virgo, far beyond our Milky Way Galaxy. Over 55 million years ago, the star emerged in an extremely wild environment, surrounded by intensely hot plasma (a million degrees centigrade) and amidst raging cyclone winds blowing at 4 million km per hour. Research using the Subaru Telescope, the National Aeronautics and Space Administration's (NASA) Galaxy Evolution Explorer (GALEX), and the Canada-France-Hawaii-Telescope (CFHT) revealed unprecedented views of the star formation process in this intergalactic context and showed the promise of future investigations of a possibly new mode of star formation, unlike that within our Milky Way About one thousand galaxies reside in a cluster filled with million-degree hot plasma and dark matter. The Virgo cluster, the nearest cluster of galaxies located about 55 million light years from Earth in the constellation Virgo, is an ideal laboratory to study the fate of gas stripped from the main body of galaxies falling into the intra-cluster medium.
