In unexpected discovery, comet contains alcohol, sugar - Yahoo News India

Scientists on Friday identified two complex organic molecules, or building blocks of life, on a comet for the first time, shedding new light on the cosmic origins of planets like Earth.

Ethyl alcohol and a simple sugar known as glycolaldehyde were detected in Comet Lovejoy, said the study in the journal Science Advances.

"These complex organic molecules may be part of the rocky material from which planets are formed," said the study.

Other organic molecules have previously been discovered in comets, most recently in comet 67P/Churyumov-Gerasimenko, on which the European space agency's Philae found several organic molecules -- including four never detected before on a comet.

Since comets contain some of the oldest and most primitive material in the solar system, scientists regard them as time capsules, offering a peek and how it all started 4.6 billion years ago.

But while the latest study does not end the debate over whether falling comets indeed seeded Earth with the components necessary for life, it does add something to our knowledge, said study co-author Dominique Bockelée-Morvan, an astrophysicist at the French National Center for Scientific Research.

"The presence of a major complex organic molecule in comet material is an essential step toward better understanding the conditions that prevailed at the moment when life emerged on our planet," she told AFP.

"These observations show a possible explanation for its (life's) origin on our planet," she added.

Other hypotheses exist too, including the gas from volcanic eruptions.

Comet Lovejoy is of particular interest to scientists because "it is one of the most active comets in Earth's orbital neighborhood," said the study.

The research was done using a 30-meter (yard) long telescope at the Institut de Radioastronomie Millimetrique in Sierra Nevada, Spain in January of 2015, when the comet was brightest and most productive.

In lighter vein.

I read the title and saw a comet that contains alcohol - this attracted my non scientific minded attention .

Someday they just might find a comet that has alcohol & soda too . That's the comet I'd like to be on.

I am not sure why this discovery is so unexpected. Sagittarius B2 is a giant cloud of gas and dust in Milky way which is full of Alcohol and that discovery was made almost a decade ago.

:o: Heck !! I wasn't aware .

With so many anomalies in Space .
Can we expect ;

1 Frozen Sun
2 Alive Rouge Planets
3 Planets with internal heating or energy systems for planets far far way from parent star .

Can Living beings of deep ocean on Earth , live without Sun in space .
Can such beings exist on Moons of Jupiter and Saturn .

1. Frozen Sun/Star - Don't know about frozen but pretty cool brown dwarfs exists, some with a surface temperature similar to summers on Earth.
The answer to point 2,3, and about life on Moons of Jupiter and Saturn is related.
- All celestial bodies generate heat in their core. But life cannot exist near the core, it has to be close to surface, and the heat radiated to surface from core would be too little and lost too soon, unless the planet/satellite has a thick layer of atmosphere or better still a thick layer of ice to keep the heat inside. So a Rouge planet or one far from its parent star can have reasonable warm surface under a thick atmosphere and support life. Titan of Saturn has a thick atmosphere and a warm surface despite its distance from Sun and is considered a possible place where life could exist.

By thick do we mean bigger atmosphere than Earth ???
Does Bigger and thicker atmosphere mean high atmospheric pressure ???

Well thicker can be either bigger and/or more denser. and yes it will have an effect on atmospheric pressure too. Titan's atmosphere is a lot denser than Earth's and atmospheric pressure is 1.5 times that of Earth..

Oooo !

Tell me one thing ,
People spending time in ISS , are they affected by the absence of Gravity ?
Like changes in body at micro level .

Similarly , Can human body resist that kind of pressure ( the one at Titan )?
