NASA's Spitzer Space Telescope finds a delicate flower in the Ring Nebula, as shown in this image. Located ~ 2000 ly from us in the constellation Lyra, the Ring Nebula is aka M57 and NGC 6720.

This video zoom sequence starts with a wide-field view of the dim constellation of Aquarius and slowly closes in on one of the largest known single objects in the Universe, the Lyman-alpha blob LAB-1. Observations show that the giant 'blob' must be powered by galaxies embedded within the cloud

NGC 24 sits ~ 25 million ly away from Earth in the constellation of Sculptor. Most of NGC 24's mass - 80 % - is thought to be held within a dark matter halo.

This image, taken by the NASA/ESA Hubble Space Telescope, shows the colorful "last hurrah" of a star like our sun. The planetary nebula in this image is called NGC 2440. The white dwarf at the center of NGC 2440 is one of the hottest known, with a surface temperature of > 200000 degrees Celsius. The nebula's chaotic structure suggests that the star shed its mass episodically. NGC 2440 lies ~ 4000 ly from us in the direction of the constellation Puppis.

This image of galaxy cluster Abell 2744, also called Pandora's Cluster, was taken by the Spitzer Space Telescope. The gravity of this galaxy cluster is strong enough that it acts as a lens to magnify images of more distant background galaxies.

This Hubble image shows the central region of a spiral galaxy known as NGC 247. Lying at a distance of ~ 11 million ly from us, it forms part of the Sculptor Group.

NGC 247's nucleus is visible here as a bright, whitish patch, surrounded by a mixture of stars, gas and dust.

Reflection nebulae M78 & NGC 2071

In the center of this image, two blue supergiant stars, called HD 38563A and HD 38563B, shine brightly. Towards the right of the image, the supergiant star illuminating NGC 2071, called HD 290861, is also seen.

M78 is located ~ 1600 ly away in the constellation of Orion.

Astronomers have discovered hyperluminous variable X-ray source located outside the core of its parent galaxy. This black hole (called XJ1417+52) likely has a mass of ~ 100000 Suns, and may have once been part of a smaller galaxy that merged with a larger one, leaving this black hole on the outskirts of the combined galaxy. Scientists refer to such objects as "wandering" black holes. These images show an X-ray closeup from Chandra and the optical full field image from Hubble.

Composite optical-HI image of NGC 262, a Type 2 Seyfert Galaxy.

The cold, neutral hydrogen is shown in blue; the stars in the galaxy and the surrounding field are shown in red.

Spiral galaxy NGC 278 lies some 38 million ly away in the northern constellation of Cassiopeia.

Its odd configuration is thought to have been caused by a merger with a smaller, gas-rich galaxy — while the turbulent event ignited the center of NGC 278, the dusty remains of the small snack then dispersed into the galaxy's outer regions.

Ancient stars, of a type known as RR Lyrae, have been discovered in the center of the Milky Way for the first time, using ESO's infrared VISTA telescope. RR Lyrae stars typically reside in ancient stellar populations over 10 billion years old. Their discovery suggests that the bulging center of the Milky Way likely grew through the merging of primordial star clusters. These stars may even be the remains of the most massive and oldest surviving star cluster of the entire Milky Way.
 
6 new images containing Chandra data have been released to celebrate American Archives Month.

Westerlund 2 - cluster of young stars - ~ 1-2 million years old - located ~ 20000 ly from us.

Radio galaxy 3C31 located 240 million ly from Earth.

Pulsar PSR J1509-5850, located ~ 12000 ly from us and appearing as the bright white spot in the center, has generated a long tail of X-ray emission trailing behind it, as seen in the lower part of the image. This pulsar has also generated an outflow of particles in approximately the opposite direction.

Supernova Remnant CTB 37A located ~ 20000 light years from Earth.

Galaxy Cluster Abell 665 generates extremely powerful shockwave. It's located ~ 2.2 billion ly from us.

Galaxy Cluster RX J0603.3+4214 (Toothbrush Cluster) [located ~ 2.7 billion ly from us]
The stem of the brush is due to radio waves (green) while the diffuse emission where the toothpaste would go is produced by X-rays observed by Chandra (purple). Visible light data from the Subaru telescope show galaxies and stars (white) and a map from gravitational lensing (blue) shows the concentration of the mass, which is mostly (~ 80%) dark matter.
 
Using data from the 64-m CSIRO radio telescope in Australia and the 100-m Max-Planck radio telescope in Germany, an international team of astronomers has created a detailed density map of neutral atomic hydrogen in our Milky Way Galaxy.

The study reveals fine details of structures between stars in the Milky Way for the first time.

Very small gas clouds appear to have helped form stars in the Milky Way over billions of years.
