News: <\/strong>Scientists are developing the Laser Interferometer Lunar Antenna (LILA) on the Moon to overcome the seismic noise, atmospheric interference, and frequency constraints that limit Earth-based detectors such as LIGO.<\/p>\n

About\u00a0<\/strong><\/td>\n\n
    \n
  • It is a proposed next-generation gravitational-wave detector<\/strong> on the surface of the Moon.<\/strong><\/li>\n
  • It detects gravitational waves in the mid-frequency range (0.1\u201310 Hz)<\/strong>.<\/li>\n
  • This range cannot<\/strong> be observed with earth-based detectors<\/strong> or with space missions planned so far.<\/li>\n
  • It is a first-of-its-kind interdisciplinary project<\/strong> between the astrophysics, geoscience, and lunar exploration communities.<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
Why moon is best location\u00a0<\/strong><\/td>\n\n
    \n
  • The Moon is the best location for this because:\n
      \n
    • The Moon has no atmosphere,<\/strong> so there is no pressure or wind noise.<\/li>\n
    • The Moon is much quieter than Earth in terms of seismic vibrations<\/strong> (2\u20133 times quieter).<\/li>\n
    • The Moon does not have oceans or weather,<\/strong> so it avoids \u201cNewtonian noise.\u201d<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
Goals<\/strong><\/td>\n\n
    \n
  • Detect and precisely locate merging black holes and neutron stars<\/strong> before they collide.<\/li>\n
  • Study the inside of the Moon and create a 3D picture<\/strong> of its internal structure.<\/li>\n
  • Test theories of gravity<\/strong> and look for new physics<\/strong>, such as dark matter<\/strong>.<\/li>\n
  • Work together with other observatories to support multi-messenger astronomy.<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
Two phases of development <\/strong><\/td>\n\n
    \n
  • LILA-Pioneer:<\/strong> Deploys a 3\u20135 km interferometer<\/strong> to achieve mid-band GW sensitivity and test lunar normal mode detection using current robotic landers.<\/li>\n
  • LILA-Horizon:<\/strong> Expands to a 40 km triangular array<\/strong> with advanced sensors and seismic isolation, designed for astronaut-assisted assembly and maintenance.<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
