We are all star stuff.

A mere 12.5 million light-years from Earth, irregular dwarf galaxy NGC 4449 lies within the confines of Canes Venatici, the constellation of the Hunting Dogs. About the size of our Milky Way's satellite galaxy the Large Magellanic Cloud, NGC 4449 is undergoing an intense episode of star formation, evidenced by its wealth of young blue star clusters, pinkish star forming regions, and obscuring dust clouds in this deep color portrait.

NGC 474 is an elliptical galaxy in the constellation Pisces. This large galaxy is known to possess tidal tails, although their origins remain unknown. These tidal tails may be related to debris left over from absorbing numerous small galaxies in the past billion years. Or the shells may be like ripples in a pond, where the ongoing collision with the spiral galaxy just above NGC 474 is causing density waves to ripple though it.

Embedded in the top right side of the nebula is the Herbig Haro object HH 450, a jet emitted from a newly forming star. The thin, red filaments in the upper-right corner of the image are the remnants of a supernova explosion. It is not yet clear whether or not the supernova remnant will collide with vdB 152. The image was generated with observations in the B (blue), V (green), I (yellow) and Hydrogen-Alpha (red) filters. In this image, North is down and East is to the right.

Astronomers find SMBH blasting molecular gas at 600,000 mph from a galaxy - Hubble image of the central part of Seyfert galaxy IC 5063. The brighter part at the center shows the region where the jets driven by the SMBH are blasting material out of the galaxy. Credit: NASA/ESA & the Hubble Space Telescope archive

Seyfert's Sextet - About 190 million light-years away in the head portion of the constellation Serpens (the Snake) are 4 interacting galaxies, the densest known galaxy group, are packed in an area 100,000 light-years across (like our Milky Way's size). The small face-on spiral galaxy (near image center) is more distant in a chance alignment and the wispy cloud (upper left) is possibly a tidal tail of stars - Image processing : © Judy Schmidt

Taken by Prosper Henry, 1885. This photograph of the Ring Nebula in the constellation Lyra shows but a three-degree section of the firmament, 1,956 light-years from earth. Once a star similar to our own sun, the nebula was formed when the star exploded, releasing gasses from its outer shell into space.

NGC 3627: Revealing Hidden Black Holes The spiral galaxy NGC 3627 is located about 30 million light years from Earth. This composite image includes X-ray data from NASA’s Chandra X-ray Observatory (blue), infrared data from the Spitzer Space Telescope (red), and optical data from the Hubble Space Telescope and the Very Large Telescope (yellow). The inset shows the central region, which contains a bright X-ray source that is likely powered by material falling onto a supermassive black hole.

Supernova N49: This is a composite image of N49, the brightest supernova remnant in optical light in the Large Magellanic Cloud. The Chandra X-ray image (blue) shows million-degree gas in the center. Much cooler gas at the outer parts of the remnant is seen in the infrared image from Spitzer (red). Taken on June 15, 2006.

NGC7129: star-forming region & reflection nebula in Cepheus; it is about 3000 ly away; stars in this nebula are very young, about 1 Ma old. The red blobs above & below the nebula are Herbig Haro objects, the result of jets of gas streaming away from young stars in the nebula

ALMA (the Atacama Large Millimeter/submillimeter Array) observed this spiral of gas around the R star of the Constellation Sculptor, an old star.

Ou4: A Giant Squid Nebula - A new investigation suggests Ou4 really lies within the emission region SH2-129 some 2,300 light-years away. The cosmic squid would represent a spectacular outflow of material driven by a triple system of hot, massive stars, cataloged as HR8119, seen near the center of the nebula. - Image Credit: Romano Corradi (IAC), et al

10 Jul 2014: NASA's Hubble Space Telescope has spotted a strange celestial "string of pearls" wrapped around the hearts of two merging elliptical galaxies... Rarely seen merger drips-new stars like beads on a string.. (more pics and video at link)

On January 21, 2014 a supernova soon after it exploded in M82, galaxy this supernova, dubbed SN 2014J, belongs to a class of explosions called “Type Ia” supernovas. These supernovas are used as cosmic distance-markers and played a key role in the discovery of the Universe’s accelerated expansion, which has been attributed to the effects of dark energy. Scientists think that all Type Ia supernovas involve the detonation of a white dwarf.

This is a pair of interacting galaxies, the barred spiral Seyfert 1 galaxy NGC 7469 (Arp 298), a luminous infrared source w/ a powerful starburst deeply embedded into its circumnuclear region, & its smaller companion IC 5283. This system is located about 200 mly away in the constellation of Pegasus

It has many dark filamentary dust lanes that extend in many directions, from the galactic nuc-leus to the inner edges of the spiral arms.

Astronomy Picture of the Day: 4/9/13 – NGC 1672

Astronomy Picture of the Day for 01 Jul 2014. Some stars explode in slow motion. Rare, massive Wolf-Rayet stars are so tumultuous and hot that they slowly disintegrating right before our telescopes. Glowing gas globs each typically over 30 times more massive than the Earth are being expelled by violent stellar winds. Wolf-Rayet star WR 124, visible near the above image center spanning six light years across, is thus creating the surrounding nebula known as M1-67.
