A perfect example of how science works.
New evidence denounces a hypothesis? Cool that makes the null hypothesis correct, mankind learned something about a body in our galaxy thanks to science. Peer review questioned the method, new research improved the mechanism of collecting data and we learned something new whilst removing something now unlikely to be true....Welcome to the scientific method.
I prefer this constructive comment.....
"Since their discovery, numerous investigations have disputed the existence of controversial planets. Their discoverers – Steve Vogt of the University of California Santa Cruz and Paul Butler of the Carnegie Institution for Science in Washington, DC – even had to publish another paper in 2012 to reaffirm the existence of Gliese 581g. They measured the colors on the violet end of the colour spectrum emitted by calcium in a star to do their corrections.
But in the new research Robertson instead measured hydrogen-emitted red color while analyzing data in Vogt and Butler's 2012 paper. He says for a cooler, low mass stars like Gliese 581 it works better, as they do not emit much blue light. In case of Gliese 581 the new measurement has shown that the system has 3 planets – a, b, and c, all of which appeared sharper – while d and g disappeared.
“I hope this research points the way toward finding exciting new planets hidden beneath stellar signals,” Robertson said."
These people are introducing data and information for mankind that will last forever, what was your last contribution to mankind and how long will it last for?
