Nearest star Fomalhaut
has a massive exoplanet, reported NASA scientists after the second study using
space telescope "Hubble".
Back in 2008,
astronomers announced that they had discovered a planet called Fomalhaut B and
shrouded in dust orbiting star Fomalhaut at a distance of 25 light years from
Earth.
More recent research,
however, has shown that this interpretation is incorrect. Based on the apparent
motion of the object and the data that were found by NASA's infrared space
telescope, "Spitzer" they argue that the object is a common cloud of
dust.
Now, however, NASA said
that the original theory was correct. Scientists to completely rethink all data
received from the telescope "Hubble" in the observations of the stars
in the period from 2004 to 2006. They found the planet because of its visible
wavelength of about 600-800 nm. They also found emanating from her violet light
of about 400 nanometers. And, in contrast to earlier studies, the scientists
found that a mysterious planet has a constant brightness.
According to the
researchers, given what is known about the behavior of dust, they discovered a
planetary object that is completely immersed in the dust, not just
free-floating clouds of dust.
