In 2012, astronomers reported a planet orbiting Alpha Centauri B, an orange star that belongs to the closest star system to the sun, located a mere 4.3 light-years from Earth (artist’s conception shown). But this detection, which must still be confirmed, left open a major question: Just how massive is this newfound neighbor of ours? The planet’s gravity tugged its sun toward and away from us, inducing a tiny Doppler shift in the star, but deriving the planet’s mass requires knowing whether we view its orbit around the star edge-on, face-on, or somewhere in between. If the orbit is edge-on, then the small Doppler shift means the planet has as little mass as Earth; but if the orbit is nearly face-on, then the planet could be as massive as Jupiter and still pull the star toward and away from us only slightly. Now, as other astronomers report in work submitted to The Astrophysical Journal, computer simulations of the planet’s history indicate that the orbit isn’t face-on, which in turn means the world is only one to three times as massive as Earth. This implies that the planet may have a terrestrial composition. Before you snap up any real estate here, though, be forewarned that the planet’s day side is hot enough to melt lead.
Swire Properties announced its fifth partnership with Art Basel in Hong Kong, which will see the company host a specially designed lounge by acclaimed architect Hugh Dutton, as well as a curated programme of high profile talks at the show.Supporting Art Basel in Hong Kong since its 2013 inaugural edition, Swire Properties and has a track record of creating and transforming places into vibrant sustainable communities, through a process that integrates arts and culture throughout. Building on a history of creating and hosting an array of arts and cultural events in its portfolios, Swire Properties will be bringing art to the public in Hong Kong with its programme this March.Guy Bradley, Chief Executive of Swire Properties, said: “Swire Properties believes that art plays a key role in enriching lives and creating sustainable communities. We are delighted to once again partner with Art Basel in Hong Kong, and are thrilled to be bringing high-calibre programmes of international standing to Taikoo Place and Pacific Place at the same time. In particular, our event space ArtisTree at Taikoo Place has over the years emerged as a serious venue for the arts, and we hope that the exhibition of the late architect Zaha Hadid’s work will inspire and engage art lovers during this exciting month of culture and creativity in Hong Kong.”
