Scientists have discovered an oddly-shaped galaxy that may contain the first newborn supermassive black hole ever spotted.
NGC 2276
Spiral galaxy NGC 2276
his is a combination of several exposures taken on the night of October 11th 1994 (UT of observation 12/10/94:10:43 to 11:00) with the 1k detector. Images were taken through three different filters approximating red (three exposures for a total of six minutes), blue (two, total 140 seconds) and...
NGC 1097
NGC 1097 at J
A Seyfert galaxy revealing its bright and active nucleus. This false-color image was made from several J-band (1.25 micron) observations and has a final FWHM of 0.5 arc seconds. This image was obtained with the Abu thermal infrared camera built by the National Optical Astronomy Observatory, on...
NGC 1232
NGC 1232 in Eridanus
NGC1232, an almost face-on spiral galaxy of type Sc in the constellation Eridanus, is about 50 million light-years away and about 100000 light-years across. This true-color picture was created from eleven images taken in the BVR pass-bands at the Kitt Peak National Observatory's 2.1-meter...
M109
M109, NGC 3992
M109 is a type SBc barred spiral galaxy in the constellation Ursa Major. M109 is around 40 to 50 million light-years away in a loose galaxy grouping which includes M108 and possibly M106. This picture was created from observations using the T2KA CCD camera at the Kitt Peak National...
M110
M110, NGC 205
M110 is the second small companion (along with M32) to our sister galaxy, M31, the Andromeda Nebula. It is classified as type E5 or E6, often with the additional "p" for peculiar because of the structure clearly visible in this short exposure image, which is probably due to dust clouds. Because...
M108
M108, NGC 3556
M108 is a type Sc spiral galaxy in the constellation Ursa Major. Almost edge-on, it shows little or no bulge and no noticeably strong center, being a motley collection of features often referred to, in classic understatement, as very dusty. The spiral structure is not very clearly delineated,...
M101
M101, NGC 5457
The giant pinwheel galaxy, M101, in the constellation Ursa Major. Of type Sc, and quite similar to our own Galaxy, it is seen almost face-on, showing the spiral arms and the intervening dust lanes (dark filaments) with great clarity in this 1975 image from the Kitt Peak 4-meter Mayall...
M88
M88, NGC 4501
None M88, a symmetrical type Sc spiral galaxy in the constellation Coma Berenices, is a member of the Virgo Cluster of galaxies. This picture is from the KPNO 0.9-meter telescope. The Virgo cluster also includes Messier galaxies M49, M58, M59, M60, M61, M84, M85, M86, M87, M89, M90, M91, M98,...
M82
M82, NGC 3034
M82, an irregular galaxy in the constellation Ursa Major. This composite color image was created from CCD observations made at the Kitt Peak National Observatory's 0.9-meter telescope in late December 1994.
M74
M74, NGC 628
None A face-on type Sc spiral galaxy in the constellation Pisces, M74 is about 30 million light-years away and about 80000 light-years across. KPNO 4-meter Mayall telescope, 1975.
M49
M49, NGC 4472
None An elliptical galaxy of type E4 in the constellation Virgo, M49 is one of the many members of the Virgo Cluster. This short exposure picture shows the smooth mostly featureless structure typical of elliptical galaxies. This picture was taken in December 1996 at the KPNO 0.9-meter telescope:...
M60
M60, NGC 4649
M60 is a large elliptical galaxy in the constellation Virgo, being about 120000 light-years across. It stands out in even small telescopes due to the proximity of the late-type spiral NGC4647 (to the NW), but such apertures may only see the central brighter regions, making M60 look considerably...
M61
M61, NGC 4303
The SABbc spiral galaxy M61 is one of the larger galaxies in the Virgo cluster, with a core dimension some 100000 light-years (6 arc minutes) across, comparable to the size of our own Galaxy. This picture was taken in February 1996 at the KPNO 0.9-meter telescope. The Virgo cluster also...
NGC 598
M33, NGC 598
The Triangulum Galaxy, M33, a type Sc spiral, was imaged by the KPNO 4-meter Mayall telescope in 1975. A member of our Local Group of galaxies, it is just visible with the naked eye.
M31
A piece of M31
Part of the Andromeda Galaxy, M31, seen through a narrow filter near, but not at, the H-alpha emission line of ionized hydrogen.
LMC
The Large Magellanic Cloud
A nearby irregular galaxy, the LMC is visible to the naked eye from the Southern Hemisphere and is a satellite to our own Galaxy. The large gaseous nebula is 30 Doradus, the Tarantula Nebula. From the CTIO Curtis Schmidt telescope, 1975.
Abell 2151
Cluster of galaxies in Hercules
None Abell 2151, the Hercules cluster, is a small, irregular cluster, with a core membership of fewer than 100 galaxies, and no strongly dominant central galaxy. It is more than 360 million light-years away and probably contains 1000 billion solar masses of sundry materials. It contains the two...
NGC 536
NGC 536: Hickson 10
This group of four galaxies is around 220 million light years away. The collection of spiral galaxies on the left side of the image include: (from top to bottom) NGC 542, NGC 536 and NGC 531. The warped arms of the latter two galaxies strongly suggests they are interacting with one another. NGC...
Abel 370
SAM images gravitational arcs in the Abel 370 cluster of galaxies
Nearly every "star" in this image is actually a galaxy. The SOAR Adaptive Module (SAM), built by CTIO/NOAO-S, is mounted on the SOAR 4.1 meter telescope: it creates an artificial laser guide star which enables the exquisite resolution seen here. The dark shadow on the left ( as seen in the full...
NGC 3842
NGC 3842
This collection of galaxies is part of a much larger cluster of galaxies (Abell 1367). From bottom left to top right the diagonal of galaxies includes NGC 3837, NGC 3842 (the large elliptical), NGC 3841, NGC 3845, NGC 3844, and NGC 3840 (the spiral at the very top right). All of these galaxies...
NGC 4088
NGC 4088
This spiral galaxy is located about 50 million lightyears away in the constellation Ursa Major. It had the third brightest supernova to be detected in 2009. It is part of a group of up to 50 other galaxies. This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak...
Milky Way
Galactic Center at 4 microns
This image shows the center of our own Milky Way Galaxy in the infrared at 4.05 microns, centered around the Brackett Alpha emission line. Despite being a combination of 42 separate frames, each separately calibrated for sky emission, the final picture still has a mean FWHM averaged over 24...
