Comet didn't bring water to Earth, according to early Rosetta results

<p>Early results from Europe’s Rosetta spacecraft challenge the theory that comets delivered water to our planet.</p> <p>On analysis of water coming from comet 67P on which the European Space Agency made history by landing a probe, it seems Earth’s water molecules contain less hydrogen than those on the comet.</p> <p>However scientists are not deterred, suggesting that comets originate from different parts of space and some may well have different types of water.</p> <p><blockquote class="twitter-tweet" lang="en" align="center"><p>My first results of <a href="https://twitter.com/hashtag/67P?src=hash">#67P</a>’s water composition find it different to Earth’s oceans.
