A shockingly bright Nova explosion occurred right on cue, but its brilliance and strange chemical signature baffled ...

In the century since Hubble’s pioneering work, astronomers like me have learned that the universe is vast and contains trillions of galaxies. In 1610, astronomer Galileo Galilei used the newly ...

This was the end of the cosmic dark ages and the start of galaxy formation. These first stars and the galaxies they formed were very different from anything we see in the modern universe.

This nova has a recurrent timescale of about four ... “By broadening our range to other galaxies using the largest astronomical telescopes available, like Gemini South, astronomers will increase ...
