Title: LISA Mission Update: The Future of Gravitational Wave Astronomy

Organization:  Deep Astronomy

Twitter @DeepAstronomy,



Have you been wondering, as I have, what the latest news is on the amazing space telescope known as LISA? Well wonder no longer as members of the Laser Interferometer Space Antenna (LISA) team will be on hand to give us an update and answer your questions.

LISA will be the first space-based gravitational wave observatory. Selected to be ESA’s third large-class mission, it will address the science theme of the Gravitational Universe. LISA will consist of three spacecraft separated by 2.5 million km in a triangular formation, following Earth in its orbit around the Sun. Launch is expected in 2034.

LISA will aim to tackle a number of key themes under the Cosmic Vision science theme of ‘The Gravitational Universe’. As part of its core science objectives, it will:

  • Study the formation and evolution of compact binary stars in the Milky Way galaxy;
  • Trace the origin, growth and merger history of massive black holes across cosmic ages;
  • Probe the dynamics of dense nuclear clusters using extreme mass-ratio inspirals (EMRIs);
  • Understand the astrophysics of stellar-origin black holes;
  • Explore the fundamental nature of gravity and black holes;
  • Probe the rate of expansion of the Universe;
  • Understand stochastic gravitational wave backgrounds and their implications for the early Universe and TeV-scale particle physics;
  • Search for gravitational wave bursts and unforeseen sources. #LiveAstronomy#DeepAstronomy

Bio: Tony Darnell is the owner of Deep Astronomy website and a host for the same hangout channel in Youtube. He has worked in the field of astronomy all my life, his first job was at a school district planetarium in Boulder, Colorado. With the exception of a stint in the Army in the 1980’s he heas worked in many aspects of astronomical research.

Most of his time has been spent writing software to retrieve, process and analyze data taken from telescopes. He has worked with data from some of the world’s largest ground-based and space-based telescopes: from the four meter Blanco telescope in Chile to the Hubble Space Telescope.

Astronomy education has always been his passion and he has written articles for website and produce astronomy videos for YouTube on the DeepAstronomy channel.
