Scientists discover one of the biggest structures in the Universe

Scientists have found a cosmic supermom. Itís a galaxy that gives births to more stars in a day than ours does in a year.

Astronomers used NASAís Chandra X-Ray telescope to spot this distant gigantic galaxy creating about 740 new stars a year. By comparison, our Milky Way galaxy spawns just about one new star each year.

The galaxy is about 5.7 billion light years away in the center of a recently discovered cluster of galaxies that give off the brightest X-ray glow astronomers have seen. It is by far the biggest creation of stars that astronomers have seen for this kind of galaxy. Other types, such as colliding galaxies, can produce even more stars, astronomers said.

But this is the size, type and age of galaxy that shouldnít be producing stars at such a rapid pace, said the authors of a study published Wednesday in the journal Nature.

"Itís very extreme," said Harvard University astronomer Ryan Foley, co-author of the study. "It pushes the boundaries of what we understand."

The unnamed galaxy ó officially known by a string of letters and numbers ó is about 3 trillion times the size of our sun, said study lead author Michael McDonald of the Massachusetts Institute of Technology.

Thereís another strange thing about this galaxy. Itís fairly mature, maybe 6 billion years old. Usually, this kind "donít do anything new... what we call red and dead," McDonald said in an interview. "It seems to have come back to life for some reason."

Because of that back-to-life situation, the team of 85 astronomers has nicknamed the galaxy cluster Phoenix, after the bird that rises from the ashes. The galaxy that is producing the stars at a rate of two per day is the biggest and most prominent of many galaxies there.

Itís "helping us answer this basic question of how do galaxies form their stars," said Michigan State University astronomer Megan Donahue, who wasnít part of the study but praised it.
