Hubble Looks Deep!

Distant Galaxies

Hubble Space Telescope has looked across 12 billion light-years of space to see some of the oldest galaxies in the cosmos — as they looked when they were young!

Looking Deep Into Space

Galaxy NGC 426

Hubble Space Telescope images an active galaxy with a black hole at its heart. This was among the first of the space telescope's black hole discoveries. Many galaxies have supermassive black holes at their hearts.

The Whirlpool Galaxy (M51)

Isaac Newton Telescope (La Palma) imaged the Whirlpool Galaxy (M51). This galaxy has spiral arms fairly bristling with bursts of star formation! Its companion is tied to M51 by a bridge of hydrogen gas.

Cartwheel Galaxy

Galaxies in Collision

Colliding galaxies affect each other for millions of years as they dance around each other in cosmic rhythms. As they approach, strong gravitational tides rip clouds of stars and gas and dust out from one of the galaxies.

Colliding Galaxies!

The Cartwheel Galaxy

It shows us what happens when two galaxies collide! Not only are they torn to bits, but hordes of bright new stars form in the aftermath!

Multiple Interactions

Hickson Compact Group 79 — Seyfert's Sextet

This distant grouping of four colliding galaxies, a distant background galaxy, and a tidal tail of stars pulled out from one of the members, is a snapshot of galactic merger on a grand scale.
