<p>Astronomers have a love-hate relationship with the atmosphere: it&#x27;s great for, you know, not dying, but it blurs astronomical images. In the latest episode of Chasing Starlight we tell you the inner workings of adaptive optics, a technique where we use powerful lasers and fast shape-shifting mirrors to measure and correct atmospheric turbulence:</p><p><a href="https://www.youtube.com/watch?v=g_QC2cLroDc" rel="nofollow" class="ellipsis" title="www.youtube.com/watch?v=g_QC2cLroDc"><span class="invisible">https://</span><span class="ellipsis">www.youtube.com/watch?v=g_QC2c</span><span class="invisible">LroDc</span></a></p><p><a href="/tags/astronomy/" rel="tag">#astronomy</a> <a href="/tags/astrophysics/" rel="tag">#astrophysics</a> <a href="/tags/astrodon/" rel="tag">#astrodon</a> <a href="/tags/science/" rel="tag">#science</a> <a href="/tags/space/" rel="tag">#space</a></p>
