The Most Detailed Catalogue Ever Made of the Visible Milky Way
| Full record: 2004Description: A density map of part of the Milky Way disk, constructed from IPHAS data. The scales show galactic latitude and longitude, coordinates that relate to the position of the centre of the galaxy. The mapped data are the counts of stars brighter than 20th magnitude detected in Sloan i, the longer (redder) wavelength broad band of the survey. Although this is just a small section of the full map, it portrays in exquisite detail the complex patterns of obscuration due to interstellar dust. This image contains 600 x 2400 independent data points, each of which represents the star count within 1 x 1 square arcminute cells (1 arcminute is 1/60th of a degree). At the level of the original exposed images, each cell is itself made up of 32,000 pixels. The typical effective angular resolution of the data is close to 1 arcsecond (1/3600th of a degree or about 10 original image pixels). The section shown features the edge of the Sagittarius spiral arm (near longitude 60 degrees) and the Cygnus-X molecular cloud complex (at around 80 degrees longitude). Both of these appear as regions of reduced star counts due to the obscuring effect of higher dust concentrations. |

Hanny's Voorerp
| Full record: 2002Description: What is that green thing? A volunteer sky enthusiast surfing through online Galaxy Zoo images has discovered something really strange. The mystery object is unusually green, not of any clear galaxy type, and situated below relatively normal looking spiral galaxy IC 2497. Dutch schoolteacher Hanny van Arkel, discovered the strange green voorwerp (Dutch for object) last year. The Galaxy Zoo project encourages sky enthusiasts to browse through SDSS images and classify galaxy types. Now known popularly as Hannys Voorwerp, subsequent observations have shown that the mysterious green blob has the same distance as neighboring galaxy IC 2497. Research is ongoing, but one leading hypothesis holds that Hannys Voorwerp is a small galaxy that acts like a large reflection nebula, showing the reflected light of a bright quasar event that was visible in the center of IC 2497 about 100,000 years ago. Pictured above, Hannys Voorwerp was imaged recently by the 2.5-meter Isaac Newton Telescope in the Canary Islands by Dan Smith, Peter Herbert and Chris Lintott (Univ. Hertfordshire).

Sh2-200
| Full record: 1852Description: Image of the planetary nebula Sharpless 2-200. This is a very evolved planetary nebula, whose central star has already faded to a low luminosity after exhausting all circumnuclear fuel. Around the filamentary inner nebula, a large faint halo is observed. This halo might be interstellar gas ionized by the central star of the planetary nebula, or alternatively ancient material ejected by the star itself when it was a red giant some 50 to 100 thousand years ago. These haloes provide very precious information about the various events of strong mass loss at the end of life of solar type stars. These mass loss events are the ultimate cause leading to the death of these stars. Image obtained using the Wide Field Camera at the 2.5m INT telescope.

The galaxy is a member of the 30 or so galaxies of the Local Group and is close enough - about 2.5 million light years - for us to study the anatomy of a galaxy in great detail. Many individual bright stars pepper the delicate spiral arms which are in turn sprinkled with pink star-forming regions. Several of the clumps of bright stars and their associated nebulae are bright enough to have been catalogued as separate objects. This image was obtained with the mosaic CCDs of the Wide Field Camera at the INT. The image is a composition of frames taken in three narrow bands: the green colour represents the galaxian emission in [OIII] nebular line, red is the H-alpha hydrogen emission and blue is mainly stellar light taken through a continuum filter centred at 555.0 nm (Stromgren Y). In only one observing night, and with two positionings of the telescope, it was possible to cover the whole galaxy which has a size of approximately one degree in the sky.

A high-redshift supernova
| Full record: 1820Description: Studies based on observations of supernovae in the farthest reaches of deep space indicate that the universe will expand forever because there isn enough mass in the universe for its gravity to slow the expansion, which started with the Big Bang. Image 1 was taken using the INT and it corresponds to a high-redshift type Ia supernova thousands of millions of light years away. When a star explodes as a type Ia supernova its brightness is similar to the host galaxy. This latter feature along with the possibility of calibrating their maximum brightness, make type Ia supernovae the best known standard candles to investigate the geometry and the dynamics of our universe. This is a CCD image obtained with the Wide Field Camera on the Isaac Newton Telescope.

M101 galaxy
| Full record: 1933Description: M101 galaxy, the Pinwheel galaxy. M101 is one of the most prominent Grand Design spirals in the sky. While quite symmetric visually, it is of remarkable unsymmetry, its core being considerably displaced from the center of the disk. Halton Arp has included M101 as No. 26 in his Catalogue of Peculiar Galaxies as a Spiral with One Heavy Arm. The picture was produced by composing three, two-minute, exposures taken through R, V and B Harris photometric filters, approximating the normal red, green and blue passbands. The area shown is approximately 30x30 arc minutes, i.e. the full field of the Wide-Field Camera CCD mosaic at the prime-focus of the Isaac Newton Telescope.

Horse Head Nebula
| Full record: 1845Description: The Horse Head Nebula. This dark dust nebula, in the shape of a horses head, protrudes into a bright emission nebula, IC 434, in the constellation Orion. A nearby naked-eye star illuminates the surface of an otherwise invisible dusty cloud, exciting the distinctive red emission from hydrogen. From this dark cloud projects yet more dust, which has the shape of the head of a horse, seen in silhouette against the glowing background. |

M51
| Full record: 1922Description: M51 galaxy, known as The Whirlpool Galaxy, is a bright spiral galaxy fairly close to us (7.5 Megaparsecs = 25 million light years). To the north of M51, at the bottom of the picture, is a companion galaxy which is being disrupted by the gravitational tidal forces of the main galaxy. Shown here is a true-colour picture using BVR imaging on the INT wide field camera. This picture was generated from three two-minute exposures. The field size of this single Loral CCD image is 12.6 arcminutes. Telescope: INT Instrument: WFC Credit: Peter Bunclark (IoA). Date: 1 January 1997 |

NGC 6822 or Barnards galaxy
| Full record: 1931Description: NGC 6822 is one of the nearest galaxies and is thus a member of the Local Group. The galaxy seems to be without symmetry and is classified as an irregular. At one end of a prominent bar a few clouds of glowing gas can be seen; at the other, bright bluish stars are scattered out into what appears to be the first signs of a straggling spiral arm. The fact that this galaxy is near enough for us to be able to resolve a large number of its individual stars makes it possible to study the star formation history based on colour-magnitude diagrams. This image was obtained using CCD imaging on the Isaac Newton Telescope. Exposure times were 900s in I, 900s in R, 1000s in V and 1200s in B.

NGC 1300 Galaxy.
| Full record: 1944Description: NGC 1300 is a classic barred spiral galaxy. It is 17 Mpc away and relatively face-on, with an inclination of about 35 degrees. Because of its size and inclination it is well-suited for a number of studies. True-colour CCD images from B, V and I imaging on the Isaac Newton Telescope. Telescope: INT Instrument: WFC Credit: J. A. Lopez Aguerri, M. Prieto, C. Munoz-Tunon, and A. M. Varela (IAC). Date: 1 January 1996 |

M96 Galaxy.
| Full record: 1943Description: M 96 or NGC 3368 Galaxy. M96 is the brightest member of the Leo I group of galaxies, which is therefore also called the M96 group. Its distance was determined to be about 41 million light years (after corrections for the distance scale which are implied by the results of ESAs Hipparcos satellite) by Nial R. Tanvir with the Hubble Space Telescope by observing Cepheid variables. Interpolated with the HST result of 35.5 million light years for its neighbor M95, a value of 38 million light years can be adopted for the group. True-colour CCD image obtained with the Isaac Newton Telescope. Telescope: INT Instrument: WFC Credit: Nial Tanvir (IoA). Date: 1 January 1995 |

he galaxy Dwingeloo 1
| Full record: 1927Description: The galaxy Dwingeloo 1. This is a barred spiral galaxy, probably one of the largest and nearest galaxies, but undiscovered until 1994. This is because it is hidden behind the disk of our own galaxy, the Milky Way - as a result more than 99% of its light is absorbed by dust in our galaxy before it reaches us. The galaxy was discovered using a combination of radio observations and INT CCD imaging. Shown here is a true colour picture using VRI CCD imaging on the INT.
