Yes. Scientists have observed a number of star
systems in the process of forming, and they have
also seen the disks of matter that will one day be
planets. The NASA has a telescope named Spitzer
Space Telescope which has spotted the very
beginnings of what might become planets.
Another astronomer from the
Harvard-Smithsonian Center for Astrophysics in
Cambridge has discovered hot extra solar (outside
our Solar System) planets. He things that these
gassy giants could even represent a new breed of
There are several new discoveries
constantly going on that reflect the evolution of
the Universe. Not only new planets are being
formed, but also stars and galaxies.
That is a question scientists are still trying to
answer!As you know, there are nine planets in our
solar system now. The planet that is farthest
from the Sun is Pluto. Beyond Pluto, there are
many objects smaller than Pluto that also revolves
around the Sun. However, in 2003, scientists
discovered a new object further away from the Sun,
which is bigger than Pluto. Scientists have not
decided if this object is actually a planet. A
final decision is expected by the end of this
year. This new planet may be named Xena; however,
this has also not been decided yet.
