NASA Discovered 7 Earth-Like Planets Around A Star In Habitable Zone, But…
Joe MartinoFebruary 22, 2017




Just a few minutes ago, NASA revealed they have found seven Earth-like planets just 40 light years away in a habitable zone. Some might even be water-rich and habitable for life.

But there is a big problem with this announcement: We already know much more than this, including that life exists outside of Earth.
“It’s the first time that so many planets of this kind are found around a same star,” Michaël Gillon, the lead author of the Nature paper announcing the discovery, said in a press conference. “The seven planets … could have some liquid water and maybe life on the surface.”
The seven exoplanets orbit a star in the constellation Aquarius called Trappist-1. And it’s a solar system said to differ greatly from our own.
Their sun, or ‘star’, has scientists fascinated because it is much smaller than our own, with an estimated one-tenth the mass of our sun and about one-thousandth its brightness. The good news for potential life on those planets is that the star’s low mass allows its planets to orbit it very closely and remain in the habitable zone.

The Challenge?




NASA seems to be holding back. Why? Information is obviously controlled and let out very slowly for specific reasons, and that could be a good thing. But at the same time, they have been hiding the truth from the public for a very long time.
This has been proven through the bevy of military, intelligence community, and even NASA whistleblowers who have come forth talking about this secrecy, as well as the known fact of life beyond Earth.
You can find out more about this in the Exopolitics section of CE. 

What We’re Doing Now




We are going to head over to NASA’s AMA on Reddit and are going to ask questions about extraterrestrial life in an attempt to get answers and raise awareness. Please join us and ask away. Please be kind, respectful and use facts. Scan this section of our site to grab some great facts. Here is an example of a high ranking testimony about known ET races.

Major Discovery! 7 Earth-Size Alien Planets Circle Nearby Star

Astronomers have never seen anything like this before: Seven Earth-size alien worlds orbit the same tiny, dim star, and all of them may be capable of supporting life as we know it, a new study reports. 
"Looking for life elsewhere, this system is probably our best bet as of today," study co-author Brice-Olivier Demory, a professor at the Center for Space and Habitability at the University of Bern in Switzerland, said in a statement. 
The exoplanets circle the star TRAPPIST-1, which lies just 39 light-years from Earth — a mere stone's throw in the cosmic scheme of things. So speculation about the alien worlds' life-hosting potential should soon be informed by hard data, study team members said. [Images: The 7 Earth-Size Worlds of TRAPPIST-1]
"We can expect that, within a few years, we will know a lot more about these planets, and with hope, if there is life there, [we will know] within a decade," co-author Amaury Triaud, of the Institute of Astronomy at the University of Cambridge in England, told reporters on Tuesday (Feb. 21).

A bizarre alien system

TRAPPIST-1 is an ultracool dwarf star that's only slightly larger than the planet Jupiter and about 2,000 times dimmer than the sun.  
The research team, led by Michaël Gillon of the University of Liège in Belgium, originally studied the star using the TRAnsiting Planets and PlanetesImals Small Telescope (TRAPPIST), an instrument at the La Silla Observatory in Chile. (This explains the star's common name; the object is also known as 2MASS J23062928-0502285.)
TRAPPIST spotted regular dimming events, which the team interpreted as evidence of three different planets crossing the face of, or transiting, the star. In May 2016, Gillon and his colleagues announced the existence of these three alien worlds, called TRAPPIST-1b, TRAPPIST-1c and TRAPPIST-1d. All three, the team reported, are roughly the size of Earth and may be capable of supporting life.

The astronomers kept studying the system, using TRAPPIST and a number of other telescopes on the ground. This follow-up work suggested that the supposed TRAPPIST-1d transits were actually caused by more than one planet, and also revealed evidence of additional possible worlds in the system. 
A three-week observation campaign by NASA's Spitzer Space Telescope in September and October 2016 helped clear all of this up. Spitzer's transit data confirmed the existence of planets b and c, but revealed that three worlds are responsible for the originally detected "TRAPPIST-1d" signal. And Spitzer also spotted two more exoplanets in the system, for a total of seven.
These seven worlds — which Gillon and his colleagues announced in the new study, published online today (Feb. 22) in the journal Nature — are all roughly Earth-size. The smallest is about 75 percent as massive as Earth, while the largest is just 10 percent heftier than our planet, the researchers said.
"This is the first time that so many planets of this kind are found around the same star," Gillon said in Tuesday's news conference. [Gallery: The Strangest Alien Planets]
All seven alien worlds occupy tight orbits, lying closer to TRAPPIST-1 than Mercury does to the sun. The orbital periods of the innermost six worlds range from 1.5 days to 12.4 days; the outermost planet, known as TRAPPIST-1h, is thought to complete one lap in about 20 days. (Spitzer spotted just one transit by TRAPPIST-1h, so its orbital path is not well-known.)
The six inner planets are in near-resonance, meaning their orbital periods are related to each other by a ratio of two small integers. This arrangement suggests that the worlds formed farther out in the system, where water was likely plentiful, and then migrated in to their current positions, study team members said.  
Data gathered by the various telescopes suggest that all six inner planets are rocky, like the Earth; not enough is known about planet h to determine its composition.

Habitable worlds?

Because the seven alien worlds orbit so tightly, they're probably all tidally locked, Gillon said. That is, they likely always show the same face to their host star, just as Earth's moon only shows the "near side" to us. 
And powerful gravitational tugs, both from TRAPPIST-1 and neighboring planets, could heat up the worlds' insides considerably, leading to lots of volcanism, especially on the innermost two worlds, the researchers added.
Despite these characteristics — extreme closeness to their star and tidal locking — the TRAPPIST-1 system is a promising place to search for E.T., study team members said.
TRAPPIST-1 is so dim and cool that its "habitable zone" — that just-right range of distances where liquid water could exist — is quite close to the star. And even tidally locked planets are thought to be potentially habitable, as long as they have atmospheres that can transport heat from the day side to the night side, Gillon said.
"You'd have just a [temperature] gradient, but it's not catastrophic for life," he said.
Indeed, modeling work performed by the team suggests that three of the seven TRAPPIST-1 planets (e, f and g) are in the habitable zone. And it's possible that, given the right atmospheric conditions, water — and, by extension, life as we know it — could exist on all seven, Gillon said.
Such speculation is preliminary, he and other team members stressed; more data will be needed before the TRAPPIST-1 planets' habitability can be gauged with confidence. Such work is already underway. The team has been studying the worlds' atmospheres with NASA's Hubble Space Telescope, for example. 
Detailed characterization — and the search for signs of possible life, such as oxygen and methane — will have to wait until more powerful instruments come online, Triaud said. But that wait shouldn't be long: NASA's $8.8 billion James Webb Space Telescope is slated to launch in late 2018, and huge, capable ground-based scopes such as the European Extremely Large Telescope and the Giant Magellan Telescope are scheduled to come online in the early to mid-2020s.
"I think that we've made a crucial step toward finding [out] if there is life out there," Triaud said. "Here, if life managed to thrive, and releases gases similar to that that we have on Earth, then we will know."
The TRAPPIST-1 system is at least 500 million years old, but its age cannot be constrained more precisely than that, Gillon said. Ultracool dwarfs such as TRAPPIST-1 generally live for 4 to 5 trillion years — about 1,000 times longer than sun-like stars.

Alien skywatching

If there were life-forms on one or more of the TRAPPIST-1 worlds, what would they see? Because of the star's dimness, even daytime skies would never get brighter than Earth's are just after sunset, Triaud said. (Still, the air would be warm, because most of TRAPPIST-1's light is radiated in infrared, not visible, wavelengths.) And everything would be suffused in a sort of salmon-colored glow.
"The spectacle would be beautiful, because every now and then you would see another planet, maybe about as big as twice [Earth's] moon in the sky, depending on which planet you were on," Triaud said.
Future work may help determine just how common such seemingly exotic vistas are in the sun's neck of the cosmic woods.
"About 15 percent of the stars in our neighborhood are very cool stars like TRAPPIST-1," Demory said in the same statement. "We have a list of about 600 targets that we will observe in the future."

NASA Announces Breakthrough in Search for Alien Life


 
It’s not a matter of if, but when.
Those words were spoken by Thomas Zurbuchen, associate administrator of the Science Mission Directorate at NASA, at today’s highly-anticipated NASA press conference. NASA held the conference today to announce the discovery of a surprising set of exoplanets in a nearby system potentially capable of sustaining life. Seven Earth-sized exoplanets orbiting the ultracool dwarf star Trappist-1, found roughly 40 light-years away in the constellation Aquarius. 

Trappist-1 is relatively close to Earth, and is found in the constellation Aquarius.
The seven newly discovered exoplanets are so close together that anyone standing on the surface of one of the planets would have a “wonderful view” of the other six planets akin to our own view of the Moon.

These planets might be our best bet for discovering life on other worlds.
The discovery of these exoplanets was made with the space-based Spitzer telescope, which can measure the brightness and composition of objects at much higher level of precision than other telescopes. The researchers stated this is the most exciting discovery made with the Spitzer telescope to date. According to Zurbuchen, this is because these planets are the best leads so far in the search for life outside of our own solar system:
This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life. Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.
Three of these new exoplanets are in the “Goldilocks Zone” around their stars, which means they are neither too cold nor too hot to support life and/or liquid water. The three planets are: Trappist-1F, which could possibly host an aqueous environment and receives the same amount of sunlight as Mars; Trappist-1E rocky, same size as Earth and receiving a similar amount of sunlight as Earth; and Trappist-1G – largest planet in the system, with a radius roughly 13% larger than Earth and which receives the same amount of sunlight as the asteroid belt between Mars and Jupiter.

The researchers described this new system as a “laboratory” for studying exoplanets surrounding relatively cool stars. Going forward, the team hopes to use the James Webb telescope to further study the chemical composition of these new exoplanets in an attempt to identify elements which might support known forms of life. According to Sara Seager, professor of planetary science and physics at MIT, this discovery gives the researchers hope that “many more life-bearing worlds out there waiting to be found.” Fingers crossed.

Keep up the good work, Spitzer.
