      <description>This is the TESS 2yr sky map. The Transiting Exoplanet Survey Satellite (TESS) is the next 
    step in the search for planets outside of our solar system, including those that could support life. 
    The mission will find exoplanets that periodically block part of the light from their host stars, 
    events called transits. TESS will survey 200,000 of the brightest stars near the sun to search for 
    transiting exoplanets. TESS aims for 50 ppm photometric precision on stars with TESS magnitude 9-15.  
    TESS launched on April 18, 2018, aboard a SpaceX Falcon 9 rocket. This dataset 
    is made of observations made during the first 2 years of the mission.  See 
    &lt;a href="https://ui.adsabs.harvard.edu/abs/2015JATIS...1a4003R/abstract"&gt;
    https://ui.adsabs.harvard.edu/abs/2015JATIS...1a4003R/abstract&lt;/a&gt; 
    for more information on the mission.
    Funding for the TESS mission is provided by NASA's Science Mission directorate.  Provenance:  TESS Data were obtained by using the code provided by Ethan Kruse at https://github.com/ethankruse/tess_fullsky.  HiPS generated by CDS. This is a service of NASA HEASARC.
