"This is why we're sending space probes to Mars and studying the outer moons of our own solar system.". Astronomers have discovered an Earth-like planet, named Proxima b, orbiting the red dwarf star Proxima Centauri, the closest star to the solar system, as seen in this artist’s impression. A planet that could be Earth's cousin is circling the nearest star beyond our sun. If Proxima b is confirmed in orbit around our nearest star, conditions on the planet are certain to be very different from conditions here on Earth, said planetary scientist Athena Coustenis, director of research for the National Centre for Scientific Research (CNRS) of France at the Meudon Paris Observatory, and chair of the European Science Foundation's space exploration committee. 8 Ways Aliens Could Contact Us, These could be the funniest animal pictures ever, 10,000-year-old footprints show journey of squirmy toddler and caregiver, Meet the zeptosecond, the shortest unit of time ever measured, Weird venomous caterpillars that look like walking toupées are invading Virginia, Physicists keep trying to break the rules of gravity but this supermassive black hole just said 'no'. Could humans ever send a probe to the planet?

"Whether life is found in the solar system or outside it, to me it's the same thing. Those are the questions that everyone wants to know," said Seth Shostak, a senior astronomer at the SETI Institute, which is dedicated to the search for life in the universe. likely to be illuminated by light with a more crimson hue, Found in space: Planet Proxima b could be Earth's closest cousin, What life would be like on an Earth-like planet around Proxima Centauri, Discovery of 'another Earth' revs plan for fly-by of laser-propelled spacecraft. Thank you for signing up to Space. "I think people will undoubtedly make an effort, but it's going to be very, very hard," Shostak said. "The big questions are, how much is it like our Earth, and does it have life? She thinks the best chances for life in the Proxima system may be on the moons of Proxima b, if there are any, because these moons would not be tidally locked to the star. Any planet with a decent ocean and atmosphere has a means to redistribute energy," he said via email. Crawford told Live Science there could be some possibilities for space travel at higher speeds, at least for robotic spacecraft; although he is an advocate of human space exploration, Crawford concedes that the distances and durations involved with interstellar travel make a human voyage unfeasible. "The biggest question now, and the one my team has been trying to solve, is does it transit?"

For me, the discovery of incontrovertible evidence of past or present life on Mars would prove my theory on alien life, without having to send probes to other star systems. The possibility of alien life has fascinated humans since our own awareness that such a thing could exist. In fact, it would take thousands of years with our current rocket technology. Our image of the day, Orionid meteor shower 2020: When, where & how to see it, The 2020 Nobel Prize in physics awarded for work on black holes. Even if the newly discovered exoplanet around Proxima Centauri is tidally locked, it could still be prime real estate for life.". "It's not the same kind of star as we have in our own solar system, so that has a few implications — and most of them are negative [for life], although there are some positive implications," Coustenis told Live Science. The Breakthrough Starshot initiative has already proposed sending a tiny nanocraft to Proxima Centauri at 20 percent of the speed of light. Just because a planet lies in the habitable zone of its star doesn't mean it's actually habitable. We don't know about each other, simply because the distances are so vast. Live Science is part of Future US Inc, an international media group and leading digital publisher. This artist's impression shows a view of the surface of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the solar system. "Chances are good...there are models (for the evolution of Proxima b) that lead to a viable Earth-like planet today," he said. "And the question is: Can it maintain an atmosphere? One such concept design, known as Project Daedalus, would emit a stream of small hydrogen bombs that detonate behind the ship, propelling it forward.

The double star Alpha Centauri AB is also visible in the image. "One side of the planet would be scorched, while the other side would be perpetually frozen. It had a thick atmosphere with a magnetosphere to protect it and potential life from the sun's radiation. [Warped Physics: 10 Effects of Faster-Than-Light Travel]. "Characterizing this planet will be very difficult if Proxima b does not transit.". This likely means that Proxima b is tidally locked, with one side always facing the star, Coustenis said. Such a mission might be possible over a time scale of around 100 years, he said. I believe that there is life all over our universe, since it would be the height of arrogance to think that we are alone. It certainly doesn't endear me to some religious organizations, but so what? Visit our corporate site. Shostak said it would take a conventional spacecraft traveling at around 36,000 miles per hour (58,000 km/h) — the speed of the New Horizons probe that launched in 2006 on a mission to Pluto and the Kuiper Belt — around 75,000 years to reach the Proxima Centauri system. "Last night when the sun set in Boston, the temperature did not fall to absolute zero. She said the main problem is that Proxima Centauri is a red dwarf star, which means it is much smaller and dimmer than our sun.

NASA's Kepler mission has thus far found thousands of exoplanets, of which approximately 40 are believed to be in or near the "Goldilocks Zone" — a just-right spot in orbit around a star where it's neither too hot nor too cold to support life as we know it. Like many big-deal discoveries, this one leads to more questions than answers.

"And by that point, your funding is gone, I think," he added.

And with the recent discovery of a possible Earth-like planet around a star in our cosmic backyard, tantalizing new questions are being raised about the possibility of finding life elsewhere in the universe. "Is there anybody there? "The discovery is inspiring," said Lisa Kaltenegger, Cornell astronomy professor and director of the Carl Sagan Institute.

And finding proof of life elsewhere in the universe would have ripple effects that reach far beyond the scientific community, he added. Editor's Note: This article has been updated to reflect that Proxima Centauri is a red dwarf, which is a small, cool type of star with an extremely long lifetime.
My view on alien life may be surprising to most. Please deactivate your ad blocker in order to see our subscription offer. Measurements indicate that Proxima b is a rocky planet, just slightly larger than Earth, orbiting the star at the right distance to be able to support liquid water on its surface, and thus perhaps life. ", Shostak told Live Science that the first indications of even a potential for life on the newly discovered planet, dubbed Proxima b, would likely come from spectroscopic analysis of the alien world — that is, if astronomers can ever directly observe Proxima b.

The early consensus seems to be that despite some potentially fundamental challenges to the development of life on Proxima b, it's still feasible and definitely worth investigating. There was a problem. The planet's orbital period is only 11 days, and it does not rotate on its axis (meaning the same side always faces the star). While this may seem like an unthinkable distance, it may not be entirely out of reach, said Ian Crawford, a professor of Earth and Planetary Science at Birkbeck College in London in the United Kingdom. But he added that the technological capacity required for such a spacecraft is far beyond anything available today, and the cost of development would be immense. Now, scientists have found such a planet orbiting a star down our own cosmic "block" — a possible rocky planet around Proxima Centauri, our closest star. Another possibility could be to use solar sails, such as the tiny laser-powered LightSail spacecraft proposed earlier this year by the Breakthrough Starshot project. ", Red dwarf stars also go through periods with strong solar flares and magnetic storm activity that could scorch any planets in close orbits and make the evolution of life very difficult, she said. In this century, it is much more likely that we could find evidence of at least past, or even current, microbial life under the surface of Mars. And either a positive or negative result would have huge implications for what we understand about the emergence of life.". [Alien World 'Proxima b' Around Nearest Star Could Be Earth-Like (Video)]. Join our Space Forums to keep talking space on the latest missions, night sky and more! The discovery of Proxima b raises renewed interest in this question. [Video: Proxima Centauri's Alien Planet Closer Than You Think — With Right Spacecraft]. It is a red dwarf, a small, cool star whose lifetime is much longer than the sun's.

"So far, no one has seen it — they've measured a very slight wobble, about the speed at which you walk ... that tells you there's a planet there, and tells you something about its mass, but it doesn't tell you anything about the conditions on the planet," Shostak said. As such, the "habitable zone" around Proxima Centauri, the just-right area around a star where liquid water could exist on a planet's surface, is much closer to the star than Earth is to the sun. But if signs of life are discovered in the Proxima system, what could we do about it? Around our sun, this would be a baking hot world.

It is a red dwarf, a small, cool star whose lifetime is much longer than the sun's. "So on one side, you will have high temperatures, and on the other side it is very cold," she added. "Beyond the merely scientific implications, there are a lot of social implications from the new perspective that the discovery of life around another star would give to our place in the universe," Crawford said. You might assume this is a deal breaker for life, but Anglada-Escudé says that's not the case. 8 Ways Aliens Could Contact Us], "I think the implications of finding an independent origin of life anywhere in the universe would be very important," Crawford said. "I think that from the philosophical point of view — set aside all the biology and other scientific implications — the philosophical import would be very substantial: sort of like being in Europe in 1492 and learning of the existence of a New World," Shostak said.

He's referring to the method of observing an exoplanet as it passes in front of, or "transits," its star and then analyzing the way the transiting planet affects the spectrum of the starlight to determine what elements are present in its atmosphere, if it has one.
