Take a deep breath: the universe is not just big it’s mind-bogglingly, practically scandalously huge. And it’s growing. A century ago, Edwin Hubble peered through his telescope and shattered human ...

A hundred years ago, astronomer Edwin Hubble revealed a universe of galaxies that existed beyond ours. His influence in astronomy continues to this day.

The Hubble Telescope, 35 years of groundbreaking discoveries, continues to surprise despite glitches, retirement risk, and replacements, remaining at the forefront of space research.

Vivian Poulin asks if the tension between a direct measurement of the Hubble constant and constraints from the early universe could be resolved by new physics.

This has led some researchers and citizen scientists to argue that the Hubble sequence — the most widely used method of categorizing galaxies — needs a serious update.

While Hubble sequence galaxies tend to follow one of two predictable evolutionary paths, nobody knows for certain how ring galaxies form.

The Hubble Classification, also known as the Hubble Sequence, is a widely recognized method for systematically categorizing ...
