By using the HARPS instrument, astronomers detected for the first time a double star where a pulsating Cepheid variable and another star pass in front of one another, which allows to measure the mass of the Cepheid. The study concluded that the mass prediction coming from the theory of stellar pulsation was correct while the value calculated was at odds with the theory of stellar evolution.<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> </p><p>The discovery of the extrasolar planet <a href="/wiki/Gliese_581_c" class="mw-redirect" title="Gliese 581 c">Gliese 581 c</a> by the team of <a href="/wiki/St%C3%A9phane_Udry" title="Stéphane Udry">Stéphane Udry</a> at <a href="/wiki/University_of_Geneva" title="University of Geneva">University of Geneva</a>'s Observatory in <a href="/wiki/Switzerland" title="Switzerland">Switzerland</a> was announced on April 24, 2007.<sup id="cite_ref-space.com_12-0" class="reference"><a href="#cite_note-space.com-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> The team used the telescope's <a href="/wiki/High_Accuracy_Radial_Velocity_Planet_Searcher" title="High Accuracy Radial Velocity Planet Searcher">HARPS</a> spectrograph, and employed the <a href="/wiki/Radial_velocity" title="Radial velocity">radial velocity</a> technique to identify the planet's influence on the star.<sup id="cite_ref-space.com_12-1" class="reference"><a href="#cite_note-space.com-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-13" class="reference"><a href="#cite_note-13"><span class="cite-bracket">[</span>13<span class="cite-bracket">]</span></a></sup> </p><p>By 2009, the telescope was used to discover 75 <a href="/wiki/Exoplanet" title="Exoplanet">exoplanet</a> candidates.<sup id="cite_ref-cnn.com_14-0" class="reference"><a href="#cite_note-cnn.com-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup> In 2011, another 50 exoplanet candidates were announced.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Contemporaries_on_commissioning">Contemporaries on commissioning</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ESO_3.6_m_Telescope&action=edit&section=3" title="Edit section: Contemporaries on commissioning"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <table class="wikitable" style="text-align: center;
