Astronomers Discover ‘Super-Earth’ around Barnard’s Star

November 15, 2018

Interesting little snippet in the I today. According to the paper, scientists have discovered a ‘super-Earth’ orbiting Barnard’s Star. The planet’s frozen, but they speculate there may nevertheless be water under its ice cap. The article runs

A frozen “super-Earth” has been discovered orbiting Barnard’s Star, the closest single star to the Sun. Despite temperatures of -150 degrees C, scientists believe there could be pockets of liquid water beneath the i8ce capable of harbouring life. Barnard’s Star is six light years from Earth and three times bigger. (p. 2).

Barnard’s Star is a red dwarf, a small, cool star smaller than the Sun. As a result, the ‘goldilocks’ zone around it, in which the temperatures are right for organic life as we know it, is also smaller and closer to the star. Way back in the 1960s one astronomer also believed he had detected two planets, about the size of Jupiter or bigger, orbiting it, but his findings were not confirmed by other astronomers.

Nevertheless, Barnard’s Star was selected as the destination for an interstellar mission by the BIS in the 1970s. Their Project Daedalus was the design for a two-stage, robotic starship using Helium-3 as fuel, mined from the atmosphere of Jupiter. They considered that the ship would be built in the 15th century, and would be able to make the trip in 50 years. This would mean that scientists, who started work on the programme in their twenties would still be alive when the ship finally reached its destination.

In the realm of Science Fiction, the Russian SF author Valentina Zhuravlyova chose it as the setting for her story, ‘The Astronaut’. This is the tale of Captain Alexei Zarubin, the captain of a doomed mission to a planet orbiting the star. In order to combat the terrible boredom experienced by space crews during long, largely automated voyages, each crewmember is required to have a hobby. Zarubin’s is painting. There’s an accident, so that the ship is unable to return to Earth unless one of them stays behind. Zarubin volunteers. Years later, another mission arrives at the Star in order to investigate what happened to him. They don’t find him, but he has left behind his paintings, showing the red-lit frozen wastes of the planet on which he was marooned. The story was included in the anthology Science Fiction Stories (London: Octopus Books 1979), Tom Boardman Jr., ed., pp. 267-84.

Of course, to fans of The Hitch-Hiker’s Guide to the Galaxy, Barnard’s Star is where the Galactic Hyperspace Development Council but the plans for the construction of a new hyperspace bypass going through the solar system, which would require the demolition of Earth. Just like the terrestrial council put the plans for the demolition of Arthur Dent’s house in a locked filing cabinet in a disused basement marked ‘Beware of the Leopard’.

While future centuries may see the construction of real spaceships heading to Barnard’s Star and its world, fortunately there seems very little likelihood of the Vogon Constructor Fleets appearing in our skies to demolish our world.
