#NASA Finds Building Blocks Of Life On Frozen Asteroid
Scientists have found evidence that #aminoacids, the chemical building blocks of life (specifically proteins), formed on the asteroid #Bennu when it was so far from the Sun as to be frozen. This directly contradicts previous belief that amino acids required liquid #water to form, through a process called Strecker synthesis. The scientists studied samples from Bennu retrieved by NASA's #OSIRISREx, published last week.

'This changes everything'. Scientists find ingredients for life on Earth in asteroid sample returned from space

Ribose and glucose detected in pristine dust samples from the asteroid Bennu

".. milestone: offering strong support to the idea that Earth’s early chemistry may have had cosmic origins."

A microscopic particle of asteroid Bennu, brought to Earth by NASA’s OSIRIS-REx mission, is manipulated under a transmission electron microscope. Researchers first reinforced it with thin strips of platinum (the “L” shape) then welded a tungsten microneedle to it.

Several bio-essential #sugars, including ribose (RNA sugar) and #glucose (metabolism substrate) were identified on #asteroid (101955) #Bennu, collected by the OSIRIS-REx #spacecraft. These sugars complete the inventory of ingredients crucial to #life.

It's now looking much more likely we'll find life elsewhere in our solar system, like on Mars, Europa, Enceladus and/or Titan.

The samples returned from asteroid Bennu contained ribose and glucose.

Finally here! Two years after #NASA 's #OSIRIS-REx mission returned samples of #asteroid #Bennu to Earth, we have now received 319 mg to study in our labs. We are hoping to determine Bennu’s isotopic composition and learn more about its “birthplace” in the Solar System.

Bouwstenen voor leven gevonden in materiaal van asteroïde Bennu

Er wordt aangenomen dat asteroïde Bennu bestaat uit puinfragmenten van een 4,5 miljard jaar oud moederlichaam, met materialen die afkomstig zijn van voorbij Saturnus, dat lang geleden werd vernietigd bij een botsing met een ander object.

Je zou het niet zeggen, maar dit is een *kleuren*foto van het materiaal dat #NASA onlangs gehaald heeft van #planetoïde Bennu (met de #OSIRISREx ruimtesonde, die met de omgekeerde stofzuiger). Uit eerste analyses blijkt dat er veel koolstof in zit. https://nasa.gov/news-release/nasas-bennu-asteroid-sample-contains-carbon-water/

Ecco come arriverà sulla #Terra il campione dell’#asteroide #Bennu, il #24settembre.
