The JCMT and UKIRT telescopes on Mauna Kea are used by astronomers to help unlock the secrets of the universe. Below are a selection of images of the telescopes and instruments used by the astronomers. A selection of science images produced are also given. For more information on the latest science undertaken with the telescopes please see the press releases web page.

    The science - SCUBA

    Although retired in 2005 the SCUBA (Submillimetre Common User Bolometer Array) archive remains a powerful tool for astronomers with published papers still including results from this instrument (for further details read this article).

    The centre of our Galaxy, the Milky Way, lies 27,000 light years from Earth. SCUBA shows us an exotic region of gas clouds, bubbles, and threads, shaped by stars, supernovae, and magnetic fields. The view is blocked at optical wavelengths by the intervening dust. Credit: D. Pierce-Price et al. In galaxies far beyond our own, SCUBA sees dust heated from star formation from when the universe was about one tenth its current age - nine tenths of the way back to the start of time. Credit: D. Hughes et al.

    The science - WFCAM

    UKIRT_gps
    Ten years in the making this data is part of the UKIDSS/GPS sky survey. The data was acquired by both UKIRT in Hawaii and the Vista telescope in Chile. This data was included in an article written by the bbc, to see the full article click here.

    The science - UFIP

    Although the primary instrument on UKIRT is WFCAM, unless a visiting instrument is in use, UKIRT has had many other instruments in its time including UFTI (UKIRT Fast-Track Imager). For more information on this and other instruments click here.
    UKIRT_ngc2392 UKIRT_ic418
    This is an image of the planetary nebula NGC 2392, also known as the Eskimo nebula. Intricate rings surround the hot, ionised gas bubble. These result as the central, dying star 'balloons off' its outer layers. A fainter, more diffuse, though larger ring surrounds the whole system; this outer ring is presumably the result of an early outburst. This image was taken with the Fabry Perot Interferometer and UFTI on UKIRT. Credit: Sandy Leggett, Tim Carroll, Chris Davis (JAC) These images of the planetary nebula IC 418 reveal a bubble of hot gas surrounding the central white dwarf star. The gas is only observed in the left-hand image because the two images were obtained at different, discrete wavelengths, using the Fabry-Perot Interferometer (FP) with the UFTI camera. The FP was tuned to transmit emission from ionised hydrogen in the left-hand image, then tuned to a 'continuum' wavelength setting, that does not transmit emission from the hot gas in this source.

    UKIRT_galcenjhk UKIRT_chicken UKIRT_w51
    A 'true-colour' mosaic of the centre of our Galaxy taken in July 1999 through the near-infrared J, H, and K band filters (30 second exposures per filter). The image covers a region extending approximately 7.5'x4.5'. The figure clearly illustrates the vast number of stars visible towards the centre of the Milky Way. The dark patches scattered throughout the region represent areas of higher obscuration or 'extinction' due to clouds of gas and dust (rather than patches where there are no stars!). Credit: Antonio Chrysostomou. This is an image of the star forming region called ON2, also known as "the Chicken Nebula". The golden-colored cloud of gas and dust harbors numerous young, red stars. These were all formed inside the nebula, as gas and dust collapsed under its own weight to form dense, cold cores and, after the onset of nuclear burning, young stars. Credit: Chris Davis (JAC) This image shows the star forming region W51. W51 is similar to the well known Orion nebula, forming both low and high mass stars. The stars themselves form in a cluster, with the more numerous low-mass stars distributed around their larger, more massive siblings. The cluster itself is still surrounded by the parent cloud from which the stars were born. The angular size of the above field is only about 100 arcsec across. Credit: M.S. Nanda Kumar, Chris Davis.
