Space Telescope Imaging Spectrograph
open-in-new
<h2 id="design">Design</h2> <p>STIS is both a spectrograph and an imaging camera, and is focused on ultraviolet light.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p><p>The STIS has three 1024×1024 detector arrays. The first is a <a href="/facts/Charge-coupled_device/l6xffIcz">charge-coupled device</a> with a 52×52 arc-second field of view, covering the visible and near-infrared spectrum from 200 nm to 1030 nm. </p><p>The other two detectors are Multi-Anode Multichannel Arrays, each with a 25×25 arc-second field of view. One is Cs2Te, and covers the near-UV between 160 nm and 310 nm. The other is CsI and covers the far-UV between 115 nm and 170 nm.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> </p> <h2 id="timeline">Timeline</h2> <ul><li>February 14, 1997- STIS installed<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a><a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> (<a href="/facts/STS-82/5TKSly8H">STS-82</a>)</li> <li>2001, Switches to Side-2 electronics after a failure in side-1.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a></li> <li>August 3, 2004- STIS goes offline due to side-2 power-failure<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a><a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a></li> <li>2009- STIS repaired<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> (<a href="/facts/STS-125/epWDLLKH">STS-125</a>)</li> <li>As of 2022<a href="https://en.wikipedia.org/w/index.php?title=Space_Telescope_Imaging_Spectrograph&action=edit">[update]</a> Operating on side-2 electronics with all optical and UV channels.<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a></li></ul> <h2 id="selected-discoveries-and-observations">Selected discoveries and observations</h2> <p>On its 20th anniversary (1997-2017) NASA noted a selection of discoveries and/or observations conducted with STIS:<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> </p> <ul><li>Survey of 20 galaxies to look for black holes</li> <li>Study of the Intergalactic Medium</li> <li>Study of the <a href="/facts/Galactic_Halo/A6jsautY">Galactic Halo</a></li> <li>Study of <a href="/facts/Interstellar_Medium/mokU0WEz">Interstellar Medium</a></li> <li>Chemical analysis of an atmosphere of an exoplanet</li> <li>Observations of a Dust Disk around <a href="/facts/Beta_Pictoris/QyTtCCHu">Beta Pictoris</a></li> <li>Study of massive stars in R136 (in the <a href="/facts/Tarantula_Nebula/nkrNzh6I">Tarantula Nebula</a>)</li> <li>Study of the star <a href="/facts/Eta_Carinae/zsrmE2Lo">Eta Carinae</a></li> <li>Study of <a href="/facts/Supernova_1987A/zHyoUpBC">Supernova 1987A</a></li> <li>Study of flows from an <a href="/facts/Active_Galaxy/qT1owvXz">Active Galaxy</a></li></ul> <h2 id="see-also">See also</h2> <p>Other Hubble instruments : </p> <ul><li><a href="/facts/Advanced_Camera_for_Surveys/bGSJsjyK">Advanced Camera for Surveys</a></li> <li><a href="/facts/Cosmic_Origins_Spectrograph/nmDJqaFE">Cosmic Origins Spectrograph</a></li> <li><a href="/facts/Faint_Object_Camera/Peu8C49N">Faint Object Camera</a></li> <li><a href="/facts/Faint_Object_Spectrograph/aRp3Euxu">Faint Object Spectrograph</a></li> <li><a href="/facts/Goddard_High_Resolution_Spectrograph/xtAH1sR5">Goddard High Resolution Spectrograph</a></li> <li><a href="/facts/Near_Infrared_Camera_and_Multi-Object_Spectrometer/hnP3GmkQ">Near Infrared Camera and Multi-Object Spectrometer</a></li> <li><a href="/facts/Wide_Field_and_Planetary_Camera/ge5UnpnD">Wide Field and Planetary Camera</a></li> <li><a href="/facts/Wide_Field_and_Planetary_Camera_2/MpGQJG8q">Wide Field and Planetary Camera 2</a></li> <li><a href="/facts/Wide_Field_Camera_3/XPTKFGBx">Wide Field Camera 3</a></li></ul> <h2 id="external-links">External links</h2> Wikimedia Commons has media related to Space Telescope Imaging Spectrograph. <ul><li><a href="http://www.spacetelescope.org/about/general/instruments/stis.html">ESA/Hubble</a></li> <li><a href="http://www.stsci.edu/hst/instrumentation/stis">The Space Telescope Imaging Spectrograph</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Tanglao, Leezel (2014-05-01).
