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.

NBD, just a shockwave from a supernova catching up with material ejected around 20,000 years before the explosion, heating it so intensely that it glows in X-ray.

The Orion Nebula (M42) was the first deep sky object I found with my telescope when I was a kid.

Caldwell 30 (also known as NGC 7331) is a handsome spiral galaxy about 45 million light-years away in the constellation Pegasus. It's mass and dimensions are very similar to our Milky Way.

The globular cluster Terzan 4, about 26,000 light years away in the constellation Scorpius. It’s about 12 billion years old, home to around a million mostly old and metal-poor stars.

A towering pillar of cold gas in the Eagle Nebula (M16), about 10 light years high. It's being boiled away by intense UV radiation from a cluster of new stars just off the top edge of the image. Stars are likely forming within.

What is it called when you see animals in clouds? I see marvelous creatures in this...like the jolly jabba-like fellow getting ready to slide down the side...
