Former spiral galaxies NGC 4038 and NGC 4039 –– the Antennae Galaxies –– are a few hundred million years into a merger that will result in a single, elliptical galaxy.

The Hubble Ultra Deep Field is a patient stare into a tiny patch of sky in the constellation Fornax. Over 11 days of exposure revealed 10,000 galaxies, including some of the oldest known.

Almost every dot, smudge, and whorl of light in the image is a galaxy. (There are a few stars in there – you can spot them by their diffraction spikes.) The deepest red ones are galaxies that probably formed when the Universe was less than a billion years old.

The Hubble Space Telescope captured this image of the Lagoon Nebula for its 28th anniversary in 2018. The image shows a region about 4 light years across; the entire nebula is roughly 55 light years high by 20 light years wide.

The Lagoon Nebula is a bit over 4000 light years away. The light in this image left the nebula around the same time the Middle Kingdom period in Egypt was getting underway.

Hubble, the Spitzer Space Telescope, and the Chandra X-ray Observatory all contributed to this multi-wavelength image of our galactic center, made for the International Year of Astronomy back in 2009.

This time-lapse of Hubble images taken between 1994 and 2016 shows the shockwave from Supernova 1987a slamming into and superheating a ring of material ejected 20,000 years earlier.

I feel a bit slammed and shocked, but in a good way.
