planets outside the solar system

For a century, astronomers have devoted their energies to studying Barnard's Star in the hope of finding planets around it. First discovered by EE Barnard at Yerkes Laboratory in 1916, this star is the closest single star system to Earth. Now, astronomers have discovered four sub-Earth-mass planets orbiting this star. One of the planets represents the discovery of the lowest-mass planet ever detected using the angular velocity technique, marking a turning point in the search for small planets in close proximity to stars.

Artistic interpretation of the system IRAS 04125+2902 (TIDYE-1). Young stars like this are covered in starspots - cooler regions of the surface of the star around them. The inner disk is emptied, leaving an intact outer disk that forms a donut-like structure around the host star. The outer disk is almost in front of the face, compared to the orbit of the planet around the star which is in front of the rim. This allows an unobstructed view of the system. If the disk was also in front of the rim, it would block the planet and host star, preventing the discovery. Credit: NASA/JPL-Caltech/R. Hurt, K. Miller (Caltech/IPAC)

This artistic concept shows what the extrasolar planet 55 Cancri e might look like. The star, also called Janssen, is a super-Earth, a rocky planet significantly larger than Earth but smaller than Neptune, orbiting its star at a distance of only 1.4 million miles (0.015 AU), completing a full orbit in less than 18 hours. (The planet Mercury is 25 times farther from the Sun compared to 55 Cancri e from its star). The system, which also includes four large gaseous planets, is located about 41 light-years from Earth, in the constellation Cancer. Credit: NASA, ESA, CSA, Ralph Crawford (STScI)

This image, taken by the SPHERE instrument on ESO's Very Large Telescope, shows the star TYC 8998-760-1 accompanied by two giant exoplanets, TYC 8998-760-1b and TYC 8998-760-1c. This is the first time that astronomers have directly observed more than one planet orbiting a Sun-like star. Both planets are visible as two bright spots in the center of the image (TYC 8998-760-1b) and lower right (TYC 8998-760-1c), indicated by arrows. Other bright spots, which are background stars, are also visible in the image. By taking different images at different times, the team was able to differentiate between the planets and the background stars. The image was taken by blocking the light from the young Sun-like star (top left of center) using a coronagraph, which allows the detection of fainter planets. The light and dark rings that you see on the image of the star are optical devices. Credit: ESO/Bohn et al
