Richest planetary system found

Scientists have discovered a planetary system containing at least five planets, orbiting the Sun-like star HD 10180 using ESO’s world-leading HARPS instrument
There’s evidence of two more planets in the same system, which would make it similar to our Solar System in terms of the number of planets.

“We have found what is most likely the system with the most planets yet discovered,” said Christophe Lovis as saying.

“Studies of planetary motions in the new system reveal complex gravitational interactions between the planets and give us insights into the long-term evolution of the system,” he added. The five strongest signals correspond to planets with Neptune-like masses — between 13 and 25 earth masses — which orbit the star with periods ranging from about 6 to 600 days. These planets are located between 0.06 and 1.4 times the earth-sun distance from their central star.

Amongst the other two planets that could exist, one would be a Saturn-like planet (with a minimum mass of 65 earth masses) orbiting in 2200 days.

So far, astronomers know of fifteen systems with at least three planets. The last record-holder was 55 Cancri, which contains five planets, two of them being giant planets.

Odysseus’ palace discovered

Greek archaeologists have claimed that they have found the palace of Odysseus after 16 years of excavation.

The discovery was reportedly made on the Ithaca Island in the Ionian Sea. “We found the ruins of a three-level palace with a staircase carved into the rock,” Noinvite.com quoted Thanasis Papadopulos as saying.

 He added that they also found a well, dating back to 13th century BC, when the Trojan War is believed to have taken place.

According to the archaeologist, the discoveries are identical to the ones described in Homer’s Odyssey, presumably written about 8th century BC.

Picture of Darwin’s family tree has been found

A photograph of the Charles Darwin’s family tree — the Galton-Darwin-Wedgwood pedigree — first exhibited in 1932, has been found in the archives of Truman State University.

A poster of the pedigree was prepared by Harry Hamilton Laughlin, Director of the Eugenics Record Office of the Carnegie Institute, and exhibited at the Third International Congress of Eugenics in 1932 at the American Museum of Natural History.

And now, a photograph of this poster has been discovered in the archives of Truman State University in Kirksville, Missouri alongside a photograph of a poster of a collection of rare Darwin family photographs, assembled by Leonard Darwin.
The original posters have not been located.

Professor Tim Berra FLS, The Ohio State University, has made this information and associated images available to Darwin scholars world-wide in a new study.

“The newly available pedigree and photographs open a window into the family life of Charles Darwin, the man. He was a husband, brother, father and grandfather, and, along the way, he also had the greatest idea ever had by the human mind,” said Berra.
