Die ETH Zürich treibt Innovationen in der Raumfahrtforschung voran, wie beispielsweise die Entwicklung des Large Interferometer for Exoplanets (LIFE). Ihre Beiträge zu bahnbrechenden Instrumenten, insbesondere dem MIRI-Instrument des James Webb Space Telescopes, sowie robotischen Plattformen wie Spacebok und SpaceHopper erweitern die Grenzen der Exploration.
[Tagesanzieger] Der ETH-Professor Sascha Quanz sucht hauptberuflich nach ausserirdischem Leben. Dafür bereitet er von Zürich aus eine Weltraummission vor. Ist das genial oder verrückt?
[phys.org] The odds are good that we are not alone in the universe. We have found thousands of exoplanets so far, and there are likely billions of potentially habitable planets in our galaxy alone. But finding evidence of extraterrestrial life is challenging, and even the most powerful telescopes we currently have may not produce definitive proof.
[Der Standard] Im Gastblog beleuchtet der Physiker Manuel Scherf die komplexen Bedingungen für die Entstehung von Leben und zeigt, welche Rolle Rote Zwergsterne dabei spielen könnten – und welche Hindernisse überwunden werden müssen. Dabei werden auch zukünftige Missionen vorgestellt, die helfen könnten, Antworten auf die uralte Frage zu finden: Sind wir allein im Universum?
[Universe Today] With LIFE, the GHGs would be easier to see than other standard biosignatures like O2, O3, CH4, and N2O. “In contrast to biosignatures, many technosignatures may provide greater specificity (less “false positive” potential), as many putative technosignatures have more limited abiotic formation channels when compared to biosignatures,” the authors explain in their research. […] This is not a futuristic scenario awaiting the development of new technology. We have the capability to do this soon, according to Daniel Angerhausen: “Our thought experiment shows how powerful our next-generation telescopes will be. We are the first generation in history that has the technology to systematically look for life and intelligence in our galactic neighborhood.”
[Space.com] After conducting a fair bit of research, scientists have come to a conclusion that may sound redundant: Life could exist on Earth.
Of course, you’re probably thinking “Well, duh.” In fact, it may feel more accurate to say that life does exist on Earth — not simply that it could. But here’s the thing. The team’s conclusion isn’t the focus of the research. It’s merely a means to an end. The plot of this story, rather, lies in precisely why these scientists reached the result.

[Phys.org] Physicists at ETH Zurich and the University of Zurich wanted to know whether the planned LIFE space mission could really detect traces of life on other planets. Yes, it can, say the researchers, with the help of observations of our own planet.
[Universe Today]We know that there are thousands of exoplanets out there, with many millions more waiting to be discovered. But the vast majority of exoplanets are simply uninhabitable. For the few that may be habitable, we can only determine if they are by examining their atmospheres. LIFE, the Large Interferometer for Exoplanets, can help.
[The Universe] Scientists have great news: there really is life on Earth. This is not a joke, but the result of an important study for the search for life in the universe. The American-European scientific team has confirmed the suitability of the Earth for life experimentally, using a model of a future space telescope, which they plan to launch into space to search for exoplanets like ours. The project was named LIFE (Large Interferometer For Exoplanets).
[The Debrief] A team of researchers from ETH Zurich and the University of Zurich has recently published a study that could significantly advance our ability to detect extraterrestrial life on exoplanets, with Earth serving as the guinea pig.
Published in The Astrophysical Journal, their work focuses on the Large Interferometer for Exoplanets (LIFE) space mission and its potential to characterize the habitability of exoplanets by observing Earth as a test object.
[Futurism] We have some truly epic news. There is indeed life on Earth.
A team of American and European scientists have confirmed this not-so-surprising observation after they simulated the workings of a proposed space telescope, and then focused the telescope on Earth, treating it like a distant exoplanet to see if the instrument could pick up evidence of life.
[India.com] According to recent study, planed LIFE mission would be able to find signs of on Exoplanets by using by using Earth as a test subject. Details here.
[NZZ] Um die lichtschwachen Planeten dennoch aufnehmen zu können, muss man tricksen. Die ETH-Forscher um Sascha Quanz möchten es mit einem sogenannten Interferometer versuchen. Die Grundidee ist, das Licht von mehreren Teleskopen zu kombinieren. Die Lichtsignale werden so überlagert, dass das Licht des Sterns sich gegenseitig auslöscht, das Licht des Planeten aber nicht. Ihre Mission nennen die Astrophysiker Life, das steht für Large Interferometer for Exoplanets und gleichzeitig für das Hauptziel der Mission: Leben entdecken.
[BBC] Future telescopes, like the Habitable Worlds Observatory and a European proposal called Life, will then try to perform this same analysis for true Earth-analogue planets around stars like our Sun. “The driving planetary class will be rocky planets in the habitable zone,” says Sascha Quanz, an astrophysicist at ETH Zürich in Switzerland who leads the Life program.
[BBC Science Focus] The next generation of space observatories have life on other planets firmly in their sights.
[Tagesanzeiger] Der Genfer Nobelpreisträger Didier Queloz sucht das Weltall mit anderen Schweizer Forschenden nach Lebenszeichen ab. Nicht alle Astronomen sind so zuversichtlich wie er.
[ETH press release] With a constellation of five satellites, the international LIFE initiative led by ETH Zurich hopes to one day detect traces of life on exoplanets. A laboratory experiment in the Department of Physics is now set to demonstrate the planned measurement method.
[earthsky.org]The two new planets – GJ 1002b and GJ 1002c – orbit the red dwarf star GJ 1002, less than 16 light-years from Earth. That is very close in terms of stellar distances. Both planets have masses similar to Earth and orbit within the star’s habitable zone. That is the region around a star where temperatures could allow liquid water to exist on rocky planets. […] In the future, the LIFE (Large Interferometer For Exoplanets) mission should also be able to study these planets more closely. LIFE is currently in a first-study phase.
[Forbes] These days almost every other week, there’s a new media flap about some newly discovered potentially habitable planet orbiting a nearby star. Trouble is, most of these exoplanet detections are indirect and researchers end up speculating about their mass, their makeup, their atmospheric compositions and whether they could ever harbor life.
But a group of planetary scientists and astrophysicists, led by a professor at ETH Zurich, has largely resurrected an idea for a flotilla of optically linked, free-flying mid-infrared telescopes that could find heretofore undiscovered earth mass planets in their star’s habitable zone.
