This breakthrough \u2014 announced in a paper published today in the journal <em>Nature<\/em> \u2014 is a result of the <a href=\"https:\/\/reddots.space\/\">Red Dots<\/a> and <a href=\"https:\/\/carmenes.caha.es\/\">CARMENES<\/a> projects, whose search for local rocky planets has already <a href=\"https:\/\/www.eso.org\/public\/news\/eso1629\/\">uncovered a new world orbiting our nearest neighbour, Proxima Centauri<\/a>.<\/p>\n<p>The planet, designated Barnard&#8217;s Star b, now steps in as the second-closest known exoplanet to Earth <a href=\"#1\">[1]<\/a>. The gathered data indicate that the planet could be a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Super-Earth\">super-Earth<\/a>, having a mass at least 3.2 times that of the Earth, which orbits its host star in roughly 233 days. Barnard\u2019s Star, the planet\u2019s host star, is a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Red_dwarf\">red dwarf<\/a>, a cool, low-mass star, which only dimly illuminates this newly-discovered world.

Super-Earths are the most common type of planet to form around low-mass stars such as Barnard\u2019s Star, lending credibility to this newly discovered planetary candidate. Furthermore, current theories of planetary formation predict that the snow line is the ideal location for such planets to form.<\/p>\n<p>Previous searches for a planet around Barnard\u2019s Star have had disappointing results \u2014 this recent breakthrough was possible only by combining measurements from several high-precision instruments mounted on telescopes all over the world <a href=\"https:\/\/www.eso.org\/public\/news\/eso1837\/?lang#3\">[3]<\/a>.<\/p>\n<p style=\"padding-left: 30px;\"><em>\u201cAfter a very careful analysis, we are 99% confident that the planet is there,\u201d<\/em> stated the team\u2019s lead scientist, Ignasi Ribas (Institute of Space Studies of Catalonia and the Institute of Space Sciences, CSIC in Spain). <em>\u201cHowever, we\u2019ll continue to observe this fast-moving star to exclude possible, but improbable, natural variations of the stellar brightness which could masquerade as a planet.\u201d<\/em><\/p>\n<p>Among the instruments used were ESO\u2019s famous planet-hunting <a href=\"https:\/\/www.eso.org\/public\/teles-instr\/lasilla\/36\/harps\/\">HARPS<\/a> and <a href=\"https:\/\/www.eso.org\/public\/teles-instr\/paranal-observatory\/vlt\/vlt-instr\/uves\/\">UVES<\/a> spectrographs.<\/p>\n<p style=\"padding-left: 30px;\"><em>\u201cHARPS played a vital part in this project.

While the planet orbits the star, its gravitational pull causes the star to wobble. When the star moves away from the Earth, its spectrum <a href=\"https:\/\/en.wikipedia.org\/wiki\/Redshift\">redshifts<\/a>; that is, it moves towards longer wavelengths. Similarly, starlight is shifted towards shorter, bluer, wavelengths when the star moves towards Earth.<\/p>\n<p>Astronomers take advantage of this effect to measure the changes in a star\u2019s velocity due to an orbiting exoplanet \u2014 with astounding accuracy. HARPS can detect changes in the star\u2019s velocity as small as 3.5 km\/h \u2014 about walking pace. This approach to exoplanet hunting is known as the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Doppler_spectroscopy\">radial velocity method<\/a>, and has never before been used to detect a similar super-Earth type exoplanet in such a large orbit around its star.<\/p>\n<p style=\"padding-left: 30px;\"><em>\u201cWe used observations from seven different instruments, spanning 20 years of measurements, making this one of the largest and most extensive datasets ever used for precise radial velocity studies.\u201d<\/em> explained Ribas. <em>\u201dThe combination of all data led to a total of 771 measurements \u2014 a huge amount of information!\u201d<\/em><\/p>\n<p style=\"padding-left: 30px;\"><em>\u201cWe have all worked very hard on this breakthrough,\u201d<\/em> concluded Anglada-Escud\u00e9. <em>\u201cThis discovery is the result of a large collaboration organised in the context of the Red Dots project, that included contributions from teams all over the world.

It will be one of the few outreach campaigns allowing the general public to witness the scientific process of data acquisition in modern observatories. The public will see how teams of astronomers with different specialities work together to collect, analyse \u00a0and interpret data, which may or may not be able to confirm the presence of an Earth-like planet orbiting our nearest neighbour . The outreach campaign consists of blog posts and social media updates on the Pale Red Dot Twitter account and using the hashtag #PaleRedDot.
