8 Tau Ceti system (Media INAF) because the stellar activity may create signals that mimic the presence of planets. Attempts at direct imaging of potential extra solar planets have proven unsuccessful to date. Infrared observation has shown there are no bodies of three or more Jupiter masses in this system. Tau Ceti is a star in the constellation Cetus that is spectrally similar to the Sun, although it has only about 78 % of the Sun’s mass. At a distance of just under 12 light-years from the Solar System, it is a relatively nearby star.

However, the method 3 Where to Go: The Search for Habitable Planets 27 employed by Herschel to measure the distances between stars was relative to Sirius, the brightest star in the night sky, which he assumed as a reference. Since he was not able to calculate the distance between Sirius and the Sun, he was not able to calculate the size of the universe. In 1838, the German astronomer F. W. Bessel became the first person to measure the distance to a star. Bessel used the parallax method. He observed the star Cigny 61 at a certain position of the Earth in her movement around the Sun and he did so along a particular line of sight.

At present, astronomers have detected planets orbiting their suns in the habitable zone, where liquid water may be present. The presence of liquid water depends on the size of the star, and the conditions on the surface, such as the amount of greenhouse effect. In the near future, advancement in observation techniques will allow whether these conditions are present in the planets situated in the habitable zone. Two scientists4 have recently written a paper on this subject. They base their projection on math and trends from the past 15 years of extra solar discoveries.
