This fifth grader is going to be getting a lot of extra credit in science this year. The Royal Astronomical Society of Canada announced the little girl’s discovery of supernova in galaxy UGC 3378 on New Years Eve. Canada’s National Post reports:

Kathryn Aurora Gray is taking her new celebrity in stride after becoming the youngest person to discover a supernova.

The 10-year-old Fredericton girl’s phone has been ringing off the hook since the Royal Astronomical Society of Canada announced her find Monday.

But the amateur astronomer knows — better than anybody, perhaps — that her discovery is fleeting.

“It’s just a blowing-up of stars so eventually it will fade away,” she said of the supernova in an interview.

Supernova Winds Shape Galaxies

The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.From Discovery News:

The explosions of massive stars may be responsible for the formation of galaxies.

After years of struggling to understand how to properly assemble a galaxy, astronomers have discovered that the answer is blowin’ in the wind. The supernova wind, that is.

New computer simulations show that winds generated by supernovas, which are the explosions of massive stars, can push stars out from the center of a dwarf galaxy. This simulation of supernova winds redistributes both ordinary matter and invisible dark matter in a way that almost perfectly matches observations of the way matter is distributed in actual dwarf galaxies. Fabio Governato of the University of Washington in Seattle and his colleagues describe their simulations in the Jan. 14 Nature.

Previous attempts to model galaxy formation based on the highly successful theory of cold dark matter — which states that invisible material must account for 85 percent of the mass of the universe — have done “an awesome job” of explaining such global properties as where, when and how many galaxies should form, notes Governato.
