Though direct observational evidence of Antlia 2 was not obtained until last year, one scientist has had a decade-long hunch that it was there. Sukanya Chakrabarti, an astrophysicist at RIT predicted in 2009 that an object packed with dark matter was causing tidal effects at the edge of the Milky Way.

Antlia 2, the "ghost of a galaxy" orbiting the Milky Way, is a dark horse in more ways than one. Not only is it so faint it was only just discovered last year, it may now be responsible for curious ripples in the hydrogen gas that makes up the Milky Way's outer disc.

The newly-discovered dark dwarf galaxy Antlia 2’s collision with the Milky Way may be responsible for our galaxy’s characteristic ripples in its outer disc, according to a study led by Assistant Professor Sukanya Chakrabarti. The Antlia 2 dwarf galaxy was discovered from the second data release of the European Space Agency’s Gaia mission, which aims to chart a three-dimensional map of our galaxy.

RIT is hosting workshops this summer to help high school students from the Rochester area learn about the science behind clean energy and fuel cells. The “Clean Energy: Electricity Generation Using Fuel Cells” workshops feature hands-on experiments and tours of RIT’s facilities.
