Claim of Alien Life on Comet Blows Up

Claim of Alien Life on Comet Blows Up

Scientists Shoot Down Claim That Alien Life May Be on Comet

The findings did not hold up to scientific scrutiny

      Scientists have picked holes in a widely-reported presentation by researchers claiming microbial life may exist on the comet now home to the Philae lander.

The claim originated in a presentation before the Royal Astronomical Society, in which researchers said the makeup of the comet, 67/P Churyumov-Gerasimenko, suggested the presence of living organisms. The scientists argued that data from Rosetta, the European Space Agency probe orbiting the comet, showed the capacity for micro-organisms to eke out life beneath the comet’s black crust.

But the findings did not hold up to scientific scrutiny. . . .

Philae Comet Could Be Home to Microbial Alien Life

Philae Comet Could Be Home to Microbial Alien Life

Astronomers say features of comet landed on by spacecraft in November, such as black crust and icy lakes, suggest living micro-organisms beneath surface
     The comet landed on by the spacecraft Philae could well be home to an abundance of alien microbial life, according to leading astronomers.

Features of the comet, named 67P/Churyumov-Gerasimenko, such as its organic-rich black crust, are most likely explained by the presence of living organisms beneath an icy surface, the scientists have said.

Rosetta, the European spacecraft orbiting the comet, is also said to have picked up strange clusters of organic material that resemble viral particles. . . .

It's Alive! Comet Lander Philae Phones Home After Months of Silence
The European Space Agency's Philae comet lander is seen by the Rosetta spacecraft in this image captured on Nov. 12, 2014 as Philae headed for its landing on Comet 67P/Churyumov-Gerasimenko. The probe went silent 60 hours later and reawakened on June 13, 2015.

     A European probe that made a bouncy landing on a comet last year, and then slipped into a silent hibernation, is alive again and phoning home.

The European Space Agency's Philae comet lander, which dropped onto Comet 67P/Churyumov-Gerasimenko from the Rosetta spacecraft last November, beamed an 85-second wake-up message to Earth via Rosetta yesterday (June 13), ESA officials announced today. It was the first signal from Philae in seven months since the probe fell silent on Nov. 15 after its historic comet landing. . . .

Are Organic Molecules Found on Philae Comet Ingredients for Life?

Philae Lander 'Sniffed' Organic Molecules on Comet's Surface

     BERLIN — The European Space Agency's Philae comet lander "sniffed" organic molecules before its primary battery ran out and it shut down, German scientists said. They said it was not yet clear whether the molecules included the complex compounds that make up proteins. One of the key aims of the mission is to discover whether carbon-based compounds, the basis of life as we know it, were brought to early Earth by comets.

Philae landed on Comet 67P/Churyumov–Gerasimenko after a 10-year journey through space aboard the Rosetta spacecraft, on a mission to unlock details about how planets and perhaps even how life evolved. It wrapped up a 57-hour marathon of scientific experiments on the comet's surface on Saturday as its batteries ran out. Philae's COSAC gas-analyzing instrument was able to sniff the comet's ultra-thin atmosphere and detect the first organic molecules after landing, the DLR German Aerospace Center said. The lander also drilled into the comet's surface, although it is still unclear whether Philae managed to deliver a sample to COSAC for analysis. . . .
