Astronomers think that the 400-million-year-old gravitational battle between NGC 1512 and its tiny buddy, NGC 1510 (on the right in the image), is driving the massive galaxy's gas supply and starburst ring, researchers said in a statement.Ph.D. It is fed by a conveyor belt of gas streaming down the two prominent bars from the galaxy's outer rim to the galactic core (hence the "barred spiral galaxy" designation). Known as a "circumnuclear starburst ring," this intense star-formation region measures 2,400 light-years across. In this observation of NGC 1512, however, the bright blue inner hub of star formation takes center-stage. That region is dotted with many blueish HII-emission regions, meaning that blasts of powerful radiation coming from nearby young stars are ionizing the clouds of hydrogen gas. Hubble, a joint project of NASA and the European Space Agency, can easily detect star formation in the galaxy's outer ring. NGC 1512 is a colossal barred spiral galaxy containing billions of stars, plus active regions of star formation. The duo is 30 million light-years from Earth. The barred spiral galaxy NGC 1512 (left) and the dwarf galaxy NGC 1510 (right) are merging with one another.
