NASA Astronomers: "Does Life Exist?"

Tate is the research director of NASA's Search for Extraterrestrial Intelligence (SETI) project. He devoted most of his career to the search for extraterrestrial life, including helping to establish "Ai". "Allan Telescope Array" searches for signs of extraterrestrial life.

Speaking at the meeting on Saturday, Tate said, "I think we will find life outside the earth in this century."

She claims that despite the current massive investment in the search for signs of extraterrestrial life, humans have only searched for a small part of the vast universe. “The sun is just one of the 400 billion stars in the Milky Way, and the Milky Way is just a vast universe. One of the 200 billion galaxies."

Tate said that searching for extraterrestrial life can be achieved by looking for biomarkers of extraterrestrial life left on planets and satellites. “We can find extraterrestrial life like this: we find biomarkers on the planets and satellites of the solar system, which we explored. Artificial products are found in the solar system, and biological features are found in the atmosphere of distant exoplanets. We may also be able to detect the products of technological civilization: the characteristics of science and technology. We may answer the question of whether or not there is life outside the Earth in the 21st century. It is very long. For a long time, we have always had questions about this."

She explained that only in her lifetime, technology has greatly improved, and astronomical data has grown rapidly. She jokingly said, "When I was studying, we knew that there were 9 planets in the solar system, but then there was one less."

Her SETI plan is to raise enough funds to upgrade the Allen telescope array - helped by her construction, in order to search for aliens' clues.

The Allen telescope array was completed in 2007 and observed 20,000 stars near the Earth.

Tate is also raising funds for the Laser SETI project, which will build a prototype system at the Lick Observatory in San Jose, California.

She hopes to build a series of cameras around the world to observe the universe and search for clues to extraterrestrial life. She said, “We can deploy cameras working in visible and infrared light at 12 locations around the world, covering the entire sky, observing all-weather observations, observing whether there are bright flashes, and other phenomena such as rapid radio storms. A project is excited."
