Map of the Universe from Johns Hopkins University and others.....

Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.

Researchers Develop a new Framework for Searching for Biosignatures

Planning ahead is something astronomy and space exploration excels at. Decadal surveys and years of engineering effort for missions give the field a much longer time horizon than many others. In the near future, scientists know there will be plenty of opportunities to search for biosignatures everywhere from nearby ocean worlds (i.e. Titan) to far away potentially habitable exoplanets. But it’s not clear what those biosignatures would look like. After all, currently there is only Earth’s biosphere to study, and it would be unfortunate to miss hints of another just because it didn’t look like those found on Earth. Now a team led by researchers at the Santa Fe Institute (SFI) have come up with a framework that could help scientists look for biosignatures that might be completely different from those found on Earth.

What'll It Take to Find Life? Searching the Universe for Biosignatures

The supertelescopes are coming, enormous ground and space-based observatories that’ll let us directly observe the atmospheres of distant worlds. We know there’s life on Earth, and our atmosphere tells the tale, so can we do the same thing with extrasolar planets? It turns out, coming up with a single biosignature, a chemical in the atmosphere that tells you that yes, absolutely, there’s life on that world, is really tough.

In old episodes of Astronomy Cast and the Weekly Space Hangout, even here in the Guide to Space, I’ve said that if we could just sample the atmosphere of a distant world, we could say with conviction if there’s life there. Just detect ozone in the atmosphere, or methane, or even pollution and you could say, “there’s life there.” Well, future Fraser is here to correct past Fraser. While I admire his naive enthusiasm for the search for aliens, it turns out, as always, things are going to be more difficult than we previously thought. Astrobiologists are actually struggling to figure out a single smoking gun biosignature that could be used to say there’s life out there. And that’s because natural processes seem to have clever ways of fooling us. What are some potential biosignatures, why are they problematic, and what will it take to get that confirmation?

How Habitable Is Titan? NASA Is Sending The Titan Dragonfly Helicopter To Find Out

There are few places in the Solar System which are as fascinating as Saturn’s moon Titan. It’s a world with a thicker atmosphere than Earth. Where it’s so cold that it rains ammonia, forming lakes, rivers and seas. Where water ice forms mountains. Like Europa and Encleadus, Titan could have an interior ocean of liquid water too, a place where there might be life. Titan’s got layers, and fortunately, there’s an awesome new mission in the works to explore it: the Titan Dragonfly mission.

A New Search for Evidence of Technological Civilizations in the Milky Way

To date, astronomers have discovered 4,164 extrasolar planets in 3,085 star systems, with another 5,347 awaiting confirmation. With this many planets available for study, researchers have been able to apply new constraints on how likely habitable planets are. In fact, the latest estimates say there could be 6 billion in the Milky Way alone! Understandably, these discoveries have renewed interest in the Search for Extraterrestrial Intelligence (SETI). But whereas the search for habitable planets is focused on finding evidence of biological processes (aka. “biosignatures”), SETI has historically been focused on evidence of technological activity – aka. “technosignatures.” With a grant from NASA, researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) and the University of Rochester are gearing up for a new study that will look for different kinds of potential technosignatures.

What are the Best Ways to Search for Technosignatures?

Midwestern sky at night Credit: : NASA’s Earth Observatory The search for extraterrestrial intelligence (SETI) has long roots in human history. With the advent of modern technologies, scientists were finally able to start scanning the skies for any sign of life. When the search first started back in the 1960s, it focused almost exclusively on trying to detect radio signals. Over the decades, no irrefutable evidence of any artificial radio signals was ever found. Financial support started to drift away from the discipline, and where the money goes so do many scientists.

Should We Reply? AI Detects Radio Signals Coming from Alien Civilizations

Should We Reply? AI Detects Radio Signals Coming from Alien Civilizations. The biggest challenge in looking for SETI signals is not at this point getting the data, but differentiating signals from human, or Earth technology, from the kind of signals we’d be looking for from technology somewhere else out in the Galaxy. And, going through millions of observations manually isn’t practical. The solution? Artificial Intelligence. And, a new machine learning method has found eight previously undetected “signals of interest” and they are very, very interesting. Look up!

The Far Side Of The Moon Is The Perfect Place For a Radio Telescope

In fact, the far side of the Moon might make one of the best platforms we have for radio telescopes. One side of the Moon is completely blocked from Earth’s constantly increasing radio traffic, giving it the perfect view to the most sensitive radio signals in the Universe. Our Book is out!

The History And Future Of The James Webb Space Telescope

Is Humanity Prepared To Discover Alien Life?

People always ask me how I think humanity will react if we discover life somewhere out there in the Universe, whether it’s bacteria under the surface of Mars, a biosignature of alien life in the atmosphere of another world, or a radio signal from another civilization. Will our civilization lose its collective mind and have a temper tantrum on a global scale? Will we become one of those purge planets from Rick and Morty? Will the discovery suddenly end all religion, as we wait for guidance from our new alien overlords? Will we gather together as a species to present a common front to whatever cosmic horrors await us beyond the Solar System? In my opinion, if I could sum up the collective response in a single word, it would be: meh. Our Book is out!

Should We Fly to Another Star Soon? Or Wait for Better Technology to Come Along?

It’s hard to really wrap your mind around the vast distances between stars. The fastest spacecraft ever launched into an interstellar trajectory right now is Voyager 1. If it was directed at the nearest star, it would take tens of thousands of years to make the journey across the interstellar gulf. Even so, groups like Breakthrough Starshot and Icarus Interstellar are working on plans right now to try and send spacecraft to other stars, ideally within our lifetimes. But we can see how quickly technology is advancing all around us, from materials science to high energy physics, not to mention reusable rockets. It seems reasonable to ask, should we invest in an interstellar mission now, or wait a few decades or even centuries for better technology to come along which could make the trip much shorter?

Catching Interstellar Objects. What If We Could Explore Oumuamua Or 2I/Borisov?

The distances to other stars are depressingly enormous. Sure, it’s incredibly far to get to Mars, Jupiter, and even Pluto, but at least you can design a robotic spacecraft to make the journey and see the science results in your own lifetime. But in the case of other stars, interstellar flight times will take thousands and even tens of thousands of years to send just a robotic mission. Fortunately, the Milky Way has got our back. Other star systems have been hurling comets and asteroids towards the Solar System. All we’ve got to do… is catch them. Our Book is out!

Searching for Technosignatures. Evidence of Intelligent Alien Civilizations

Are we alone in the Universe? It’s one of the most difficult and important questions that humanity can ask. As Arthur C. Clarke noted, it’s equally terrifying whether the answer is yes or no. So if you’re going to find evidence of extraterrestrial civilizations, you want to be absolutely certain about your evidence.

Construction Begins on the Square Kilometer Array

At twin ground-breaking ceremonies today in South Africa and Australia, project leaders formally marked the start of construction on what will be the largest radio telescope ever built. Dubbed the Square Kilometer Array Observatory (SKAO) – referring to the total area the antennas and dishes will cover when complete – the telescope is not a single detector but rather a collection of them, connected across two continents using a technique known as interferometry (the same technique used by the Event Horizon Telescope, which took the first ever photograph of a black hole in 2019).

A Lack of Alien Signals Actually Tells Us a Lot

In a recent study published in The Astronomical Journal, a researcher from the École Polytechnique Fédérale de Lausanne (EPFL) discusses the potential reasons why we haven’t received technoemission, also called technosignatures, from an extraterrestrial intelligence during the 60 years that SETI has been searching, along with recommending additional methods as to how we can continue to search for such emissions.

Astronomers scanned 12 planets for alien signals. Results were surprising!

Recently, an international team of researchers from the SETI Institute, Breakthrough Listen, and multiple universities scanned twelve exoplanets for signs of technological activity (aka "technosignatures"). Their observations were timed to coincide with the planets passing in front of their sun relative to the observer (i.e., making a transit). While the survey did not detect any definitive evidence of technosignatures, they did identify two radio signals of interest that warrant follow-up observation. This new technique could vastly expand the field of SETI and create all kinds of opportunities for future research. The team was led by Sofia Z. Sheikh, a graduate student with the SETI Institute and Berkeley SETI Research Center (UC Berkeley), and other members of a graduate SETI program run by the Penn State Extraterrestrial Intelligence Center (PSETIC). They were joined by teams from Breakthrough Listen, the Center for Exoplanets and Habitable Worlds (CEHW), the International Center for Radio Astronomy Research (ICRAR), and multiple universities and research institutes . The paper that details their research is scheduled to be published in The Astronomical Journal. The search for radio signals has been an established SETI convention since the first survey was conducted in 1961 . This was Project Ozma, led by the late and legendary Cornell astrophysicist Frank Drake, for whom the Drake Equation is named. In recent years, the field of SETI has expanded considerably, with next-generation radio telescopes and new data analysis techniques (many of which incorporate machine learning) have become available. The kinds of technosignatures researchers could look for are also expanding, with proposals ranging from directed energy and neutrinos to gravitational waves.
