- 4251 - SIX PLANET SOLAR SYSTEM - Astronomers have discovered six planets orbiting a bright nearby star in perfect rhythmic harmony. This rare, frozen-in-time cosmic wonder that can help explain how solar systems across the galaxy came to be. This is a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago.
-------------------------- 4251 - SIX PLANET SOLAR SYSTEM
- A six planet solar
system in perfect synchrony has been found in the Milkyway Galasxy. Astronomers have discovered six planets
orbiting a bright nearby star in perfect rhythmic harmony. This cosmic wonder
may help explain how solar systems across the galaxy came to be.
-
- This solar system
is 100 light-years away in the constellation Coma Berenices. A light-year is
5.8 trillion miles. None of the
planets in perfect synchrony are within the star's so-called habitable zone,
which means little if any likelihood of life, at least as we know it.
-
- This star, “HD 110067”, may have even more planets. The
six found so far are roughly two to three times the size of Earth, but with
densities closer to the gas giants in our own solar system. Their orbits range
from nine to 54 days, putting them closer to their star than Venus is to the
sun and making them exceedingly hot.
-
- As gas planets,
they're believed to have solid cores made of rock, metal or ice, enveloped by
thick layers of hydrogen.
-
- This rare,
frozen-in-time cosmic wonder can help explain how solar systems across the
galaxy came to be. The innermost
planet completes three orbits for every two by its closest neighbor. It's the
same for the second- and third-closest planets, and the third- and
fourth-closest planets.
-
- The two outermost
planets complete an orbit in 41 and 54.7 days, resulting in four orbits for
every three. The innermost planet, meanwhile, completes six orbits in exactly
the time the outermost completes one.
-
- All solar systems,
including our own, are thought to have started out like this one. But it's
estimated only 1-in-100 systems have retained that synchrony, and ours isn't
one of them. Giant planets can throw things off-kilter. So can meteor
bombardments, close encounters with neighboring stars and other disturbances.
-
-While astronomers know of 40 to 50 in-sync solar systems,
none have as many planets in such perfect step or as bright a star as this one.
-
- What does it take
for the building blocks of life to have formed in one of these systems? While life on Earth is relatively new,
geologically speaking, the ingredients that combined to form it might be much
older than once thought.
-
- The simplest amino
acid, carbamic acid, could have formed alongside stars or planets within
interstellar ices. The findings could be used to train deep space instruments
like the James Webb Space Telescope to search for prebiotic molecules in
distant, star-forming regions of the universe.
-
- It has long been
hypothesized that one of the building blocks for life, amino acids, could have
formed during reactions in the "primordial soup" of the early,
prebiotic Earth. However, another theory suggests that amino acids could have
been carried to the Earth's surface by meteorites.
-
- These space rocks
might have picked up the molecules from dust or interstellar ices which are
water and other gases frozen solid by the cold temperatures of outer space. But
because meteorites came from far away in the universe. Where did these molecules form, and when?
-
- To recreate this
environment they created a model interstellar ices containing ammonia and
carbon dioxide, deposited onto a silver substrate and slowly heated. Using
Fourier transform infrared spectroscopy, they found that carbamic acid and
ammonium carbamate started to form at -348° Fahrenheit and -389°. These low temperatures demonstrate that
these molecules, which can turn into more complex amino acids, could have formed
during the earliest, coldest stages of star formation.
-
- They found that at
warmer temperatures, similar to those produced by a newly formed star, two
carbamic acid molecules could link together, making a stable gas. They
hypothesized that these molecules could have been incorporated into the raw
materials of solar systems including our own and then delivered to the early
Earth by comets or meteorites once the planet formed.
-
- While life on
Earth is relatively new, geologically speaking, the ingredients that combined
to form it might be much older than once thought.
