    The dwarf planet Ceres keeps looking better and better as a possible home for alien life.

    NASA's Dawn spacecraft has spotted organic molecules — the carbon-containing building blocks of life as we know it — on Ceres for the first time, a study published today (Feb. 16) in the journal Science reports.

    And these organics appear to be native, likely forming on Ceres rather than arriving via asteroid or comet strikes, study team members said. [Photos: Dwarf Planet Ceres, the Solar System's Largest Asteroid]

    "Because Ceres is a dwarf planet that may still preserve internal heat from its formation period and may even contain a subsurface ocean, this opens the possibility that primitive life could have developed on Ceres itself," Michael Küppers, a planetary scientist based at the European Space Astronomy Centre just outside Madrid, said in an accompanying "News and Views" article in the same issue of Science.

    "It joins Mars and several satellites of the giant planets in the list of locations in the solar system that may harbor life," added Küppers, who was not involved in the organics discovery.

    Ceres finds keep rolling in
    The $467 million Dawn mission launched in September 2007 to study Vesta and Ceres, the two largest objects in the main asteroid belt between Mars and Jupiter.

    Dawn circled the 330-mile-wide (530 kilometers) Vesta from July 2011 through September 2012, when it departed for Ceres, which is 590 miles (950 km) across. Dawn arrived at the dwarf planet in March 2015, becoming the first spacecraft ever to orbit two different bodies beyond the Earth-moon system.

    During its time at Ceres, Dawn has found bizarre bright spots on crater floors, discovered a likely ice volcano 2.5 miles (4 km) tall and helped scientists determine that water ice is common just beneath the surface, especially near the dwarf planet's poles.

    The newly announced organics discovery adds to this list of achievements. The carbon-containing molecules — which Dawn spotted using its visible and infrared mapping spectrometer instrument — are concentrated in a 385-square-mile (1,000 square km) area near Ceres' 33-mile-wide (53 km) Ernutet crater, though there's also a much smaller patch about 250 miles (400 km) away, in a crater called Inamahari.

    And there could be more such areas; the team surveyed only Ceres' middle latitudes, between 60 degrees north and 60 degrees south.

    "We cannot exclude that there are other locations rich in organics not sampled by the survey, or below the detection limit," study lead author Maria Cristina De Sanctis, of the Institute for Space Astrophysics and Space Planetology in Rome, told Space.com via email.

    Dawn's measurements aren't precise enough to nail down exactly what the newfound organics are, but their signatures are consistent with tar-like substances such as kerite and asphaltite, study team members said.




    Organics probably native
    "The organic-rich areas include carbonate and ammoniated species, which are clearly Ceres' endogenous material, making it unlikely that the organics arrived via an external impactor," co-author Simone Marchi, a senior research scientist at the Southwest Research Institute in Boulder, Colorado, said in a statement.

    In addition, the intense heat generated by an asteroid or comet strike likely would have destroyed the organics, further suggesting that the molecules are native to Ceres, study team members said.

    The organics might have formed via reactions involving hot water, De Sanctis and her colleagues said. Indeed, "Ceres shows clear signatures of pervasive hydrothermal activity and aqueous alteration," they wrote in the new study.

    Such activity likely would have taken place underground. Dawn mission scientists aren't sure yet how organics generated in the interior could make it up to the surface and leave the signatures observed by the spacecraft.

    "The geological and morphological settings of Ernutet are still under investigation with the high-resolution data acquired in the last months, and we do not have a definitive answer for why Ernutet is so special," De Sanctis said.

    It's already clear, however, that Ceres is a complex and intriguing world — one that astrobiologists are getting more and more excited about.

    "In some ways, it is very similar to Europa and Enceladus," De Sanctis said, referring to ocean-harboring moons of Jupiter and Saturn, respectively.

    "We see compounds on the surface of Ceres like the ones detected in the plume of Enceladus," she added. "Ceres' surface can be considered warmer with respect to the Saturnian and Jovian satellites, due to [its] distance from the sun. However, we do not have evidence of a subsurface ocean now on Ceres, but there are hints of subsurface recent fluids."

    The life building blocks are common in the universe. The higher life forms are very rare and intelligent life forms could be one per galaxy.

    We will get more information in the near future there are a few interesting projects coming up in the next few years


    Private sector is involvement is going to be a big boost to space exploration.

    It's talking about the physical universe as being part of our dominion. Forgot what exactly it said but remember reading it somewhere. Space exploration is not forbidden by your religion.

    Edit: Found what you were quoting 2:22, that's just talking about not attributing any force of nature as equal to God, don't commit polytheism.

    This wasn't the verse I was talking about nor does it talk about space exploration. Just because I'm not affiliated with Islam or any other religion, don't think for second I'm a fool.

    Quran is also said that Allah made 7 sky and 7 earth like planet where intelligent life is flourishing, 1/4 of Quran is insisting humans to investigate on science matters

    And when thy Lord said unto the angels: Lo! I am about to place a viceroy in the earth, they said: Wilt thou place therein one who will do harm therein and will shed blood, while we, we hymn Thy praise and sanctify Thee? He said: Surely I know that which ye know not. (2:30)

    Pickthall
    But Satan caused them to deflect therefrom and expelled them from the (happy) state in which they were; and We said: Fall down, one of you a foe unto the other! There shall be for you on earth a habitation and provision for a time. (2:36)

    Pickthall
    And when Moses asked for water for his people, We said: Smite with thy staff the rock. And there gushed out therefrom twelve springs (so that) each tribe knew their drinking-place. Eat and drink of that which Allah hath provided, and do not act corruptly, making mischief in the earth. (2:60)

    Pickthall
    O mankind! Eat of that which is lawful and wholesome in the earth, and follow not the footsteps of the devil. Lo! he is an open enemy for you. (2:168)

    Pickthall
    The month of Ramadan in which was revealed the Qur'an, a guidance for mankind, and clear proofs of the guidance, and the Criterion (of right and wrong). And whosoever of you is present, let him fast the month, and whosoever of you is sick or on a journey, (let him fast the same) number of other days. Allah desireth for you ease; He desireth not hardship for you; and (He desireth) that ye should complete the period, and that ye should magnify Allah for having guided you, and that peradventure ye may be thankful. (2:185) (Ramadan possible on earth)


    These and many other verses show that we are bound to earth... not even moon was our territory.

    Quran 55:33, 15:14, and 15:15. Those were what I was talking about Space Exploration which is allowed if capable, some people will still just call it magic.
    No, I'm not even going to waste anymore time with your fundamentalist ignorant type. Putting it in bold, caps lock, italic, underlined, or any color of the rainbow. It will not work.

    I've defended the position your Religion takes on this matter and go no further. This religious matter is closed @WebMaster , @The Eagle do as you wish I'm done.

    Yes all universe is Allah's territory including earth but also in Quran Allah is also insisting that we should investigate and research on space frontiers and all science matters, you narrow minded kid:blah:

    There is some thing called being realistic. Being realistic is not narrow mindedness.

    science has reached its limits. Its stuck in understanding atoms. its stuck in going beyond earths limits. stuck in making life eternal.
    most scientists have been proven they are stuck. some have become humble and started working for betterment of humanity on this planet others have gone arrogant and keep on inventing such lies and propaganda.

    The only motivation i see behind this space activity is to prove to the people that Quran is not the governing book of this universe. Their false hope is that they live on moon for a week or so and start saying Quran does not describe life on moon and bla-bla.

    You guys please come out of fantasy world. wake up and know that Quran mentions Jews, Christians, Muslims, Polytheists, Masjidil Haram, Ramadan, Fish, Wolf, Earth, Islam. Do you want to make Allah sound stupid ? A star is a star "نجم" "نجوم" . For humans it WILL remain a star.
    And being realistic i expect dooms day within next 1000 years. I do not claim i know it. but i expect it.

    Ok you go to moon with a speed of 1000 km per hour in a rocket and spend 16 days in your small cabin and please come back. Americans already did that using 386 25 Mhz computers dacades ago.

    and please also know that strongest possible materials have already been discovered out of 110 basic elements and they are not capable enough for such missions.
