Astronomers Call to Continue the Search for Extraterrestrial Life and Other 'Earth-Like Worlds'
A U.S. survey of astronomers puts the search for extraterrestrial life at the top of their to-do list for the next 10 years.
In a report issued Thursday by the National Academy of Sciences, Engineering and Medicine, astronomers stressed the need to continue the hunt for potentially habitable planets circling other stars, building on what they called the “extraordinary progress” already made.
The ultimate goal, they said, is to capture pictures of any Earth-like worlds that might be out there.
“Life on Earth may be the result of a common process, or it may require such an unusual set of circumstances that we are the only living beings within our part of the galaxy, or even in the universe. Either answer is profound,” the report said.
“The coming decades will set humanity down a path to determine whether we are alone.”
Also ranked high: exploring the origins and evolution of black holes, neutron stars, galaxies and the entire universe.
The survey is done every 10 years and draws input from scores of mostly U.S.-based scientists.
The latest report recommends that NASA create a new office to oversee space observatories and overlapping missions in the coming decades.
First up should be a telescope that’s significantly bigger than the Hubble Space Telescope, one that would be capable of spotting planets that are 10 billion times fainter than their stars, the report said.
Once the necessary technologies are ready, this telescope could be ready to launch in the 2040s for around $11 billion, followed by other mega observatories in the billions of dollars.
The long-awaited astrophysics decadal survey, Astro2020, is now here. It calls on NASA to start on a large space telescope for launch in the 2040s, as part of bigger multi-decade program that will later include far-IR and X-ray telescopes. https://t.co/ysnBtGfNGK

But the report emphasized the need for smaller, more modest missions as well.
Launching one spacecraft per decade with a cost cap of $1.5 billion, it said, balances science with timeliness.
The report noted the threat in years past of cost overruns and delays in major projects.
Due to finally blast off next month, the NASA-led James Webb Space Telescope — designed to scan the early universe and explore the atmospheres of other worlds — is a prime example of that.
Yet its launch promises to be “a momentous occasion that will shape the course of astronomy and astrophysics in the coming decades,” the report said.
