Search for alien life is the top priority of astronomers over the next ten years, major Nasa-sponsored report says
The search for alien life is the top priority of astronomers in the next ten years, according to a major Nasa-sponsored report.
Humanity must keep hunting for worlds that could be home to other kinds of life, the survey of mostly US astronomers found, as catalogued in a report issued today by the National Academy of Sciences, Engineering and Medicine.
It noted that we have already made “extraordinary progress” in finding exoplanets and surveying them. The eventual goal would be to take photographs of other worlds that might be like Earth.“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 stated. “The coming decades will set humanity down a path to determine whether we are alone.”
The survey also called for more work to look into black holes, neutron stars, galaxies and the universe.
And it noted the glaring lack of diversity among those who work on astronomy projects, suggesting that Nasa should look at the demographic makeup of teams when deciding what research goes ahead.
The survey is done every 10 years and draws input from scores of mostly US-based scientists.
It helps establish the priorities and recommendations that will guide astronomy and planetary research in the years that follow.
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 that would be capable of spotting planets that are 10 billion times fainter than their stars, the report stated. 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.
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 stated, 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 noted.
The report — sponsored by Nasa, National Science Foundation, Energy Department and Air Force — noted that the survey was conducted during a health crisis. While the pandemic has underscored the importance of science, “the ultimate economic and social impacts of the pandemic remain unclear, adding to the uncertainty of the future landscape.”
The report urged Nasa, the National Science Foundation and Energy Department to treat harassment and discrimination “as forms of scientific misconduct,” add more diversity to its upper levels, and consider diversity when funding a project.
