NEW PLANET IS LARGEST DISCOVERED ORBITING TWO SUNS
If you cast your eyes toward the constellation Cygnus
the Swan, you’ll be looking in the direction of the
largest planet yet discovered around a double-star
system. It’s too faint to see with the naked eye, but
a team led by astronomers from NASA’s Goddard
Space Flight Center and San Diego State University
used the Kepler Space Telescope to identify the new
planet, Kepler-1647b.
Planets that orbit two stars are called
circumbinary planets, or “Tatooine” planets,
after Luke Skywalker’s homeland in “Star Wars.”
To detect planets, the Kepler telescope looks for
slight dips in brightness that hint a planet might
be transiting in front of a star, blocking some of
the star’s light.
“But finding circumbinary planets is much
harder than finding planets around single stars,”
said SDSU astronomer William Welsh, one of the
paper’s coauthors. “The transits are not regularly
spaced in time and they can vary in duration and
even depth.”
Once a candidate planet is found, researchers
employ advanced computer programs to determine
if it really is a planet. It can be a grueling process.
Laurance Doyle, a coauthor on the paper and
astronomer at the Carl Sagan Center, SETI Institute,
noticed a transit back in 2011, but more data and
several years of analysis were needed to confirm that
the transit was indeed caused by a circumbinary
planet. A network of amateur astronomers in the
KELT Follow-Up Network provided additional
observations that helped the researchers estimate
the planet’s mass.
Kepler-1647b is 3,700 light-years away and
approximately 4.4 billion years old, roughly the
same age as the Earth. The stars are similar to the
Sun, with one slightly larger than our home star and
the other slightly smaller. The planet has a mass and
radius nearly identical to that of Jupiter, making it
the largest transiting circumbinary planet ever
found.
“It’s a bit curious that this biggest planet took
so long to confirm, since it is easier to find big
planets than small ones,” said SDSU astronomer
Jerome Orosz, another coauthor on the study. “It
took so long to confirm because its orbital period
is so long.”
` The planet takes 1,107 days (just over 3 years)
to orbit its host stars, the longest period of any
confirmed transiting exoplanet found so far. The
planet is also much further away from its stars
than any other circumbinary planet, breaking
with the tendency for circumbinary planets to
have close-in orbits. Interestingly, its orbit puts
the planet within the so-called habitable zone.
Like Jupiter, however, Kepler-1647b is a gas giant,
making the planet unlikely to host life. Yet if the
planet has large moons, they could potentially be
suitable for life.
“Habitability aside, Kepler-1647b is important
because it is the tip of the iceberg of a theoretically
predicted population of large, long-period
circumbinary planets,” Welsh said.
“It looks like more than 40% of circumbinary
planets are in the habitable zones of their stars,” said
Doyle. “It seems that the scene from Star Wars where
Luke Skywalker is watching the double sunset may
not be so rare after all. But physics might be more
difficult—everything from shadows to rainbows
would come in pairs!”

A Weekly Religion Column by Rev. James Snyder
GO AHEAD - MAKE DAD’S DAY
Throughout the year, many days of celebration are
tucked capriciously into the calendar. So much
so, it is hard to find any day of the year where
something or someone is not being observed,
which has benefited the greeting card company,
you can be sure. I am not positive, but I think they
have had a great deal to do with designating these
days.
Some days are celebrated a little more
enthusiastically than others. The Fourth of July
has firecrackers; Halloween has funny and scary
costumes, not to mention bags of candy; and
Christmas boasts the Christmas tree and jolly
old St. Nick with all his presents, and it is hard to
compete with Christmas parties when it comes to
celebrations.
And we come to Mother’s Day. According
to experts, more telephone calls are placed on
Mother’s Day than any other day of the year. Also,
try to walk into a restaurant and get a seat on that
certain Sunday.
There is a theory, which I subscribe to personally,
stating the reason Father’s Day is so lame is
because so much has been spent on Mother’s Day,
there is nothing left.
I think there should be a rule that says, whatever
Mother’s Day costs fathers, mothers should spend
on Father’s Day. This would do one of two things;
decrease Mother’s Day or puff Father’s Day
spending. Personally, I am in favor of puffing.
Perhaps with some effort, Father’s Day could be
a little more exciting. I am not saying this just
because I am a father. Well, maybe I am, but if I
don’t who will?
Fathers in general are rather humble and
hesitant to speak about themselves. Contrary
to popular opinion, every father knows talk is
not cheap, and because he has spent so much
on Mother’s Day, he simply is practicing good
manners and shuts up.
However, every father needs to know he is truly
appreciated by his family. Although you cannot
buy a father, it is possible to rent him on occasion.
I am in favor of celebrating Father’s Day “any
which way you can.” It really does not matter to
the father involved. Any father would consider
his child a “million dollar baby” if he or she
would just give a Father’s Day card to him, along
with a nice hot cup of coffee while sitting in his
favorite chair reading the newspaper. Nothing the
children did throughout the year would remain
“unforgiven” if something this simple were done
on Father’s Day.
As it stands, Father’s Day is celebrated “every
which way but loose,” and I believe it is time this
has stopped. Too many loose ends concerning
Father’s Day. It is a “true crime” the way certain
things are left hanging concerning fathers. Some
fathers have felt like “the dead pool” around
Father’s Day, not knowing exactly what to expect.
Mother’s Day is rather simple. Every mother
knows that she will get certain things; flowers,
a Mother’s Day card and dinner at her favorite
restaurant.
By the time Father’s Day comes around
everybody is so exhausted from Mother’s Day, not
to mention most fathers are broke, nobody knows
exactly how to make dad’s day special or, more
importantly, who will finance it.
Too many people are uptight about Father’s
Day and feel like they are running “the gauntlet.”
When I say people, I am referring primarily to
Yours Truly. Nobody seems to know what to do
about good ole dad on his special day.
Fortunately, I have some ideas along this line.
With some of the presents I have received over
the years, I am beginning to think my children
imagine me as a “space cowboy,” or maybe a “high
plains drifter” driving around in a “pink Cadillac”
heading for “the bridges of Madison County.”
When it comes to being a father, I assure you
I am not “the rookie” walking on a “tightrope,”
directly “in the line of fire” running toward
“heartbreak ridge.” I have quite a bit of experience
being a father, going back more than 40 years.
As a father, I have three children notched on my
belt. At times, I have felt like “the enforcer” and
the only way to deal with those children was to
use “magnum force” and “hang ‘em high.”
I must confess at times I felt like a “pale rider”
sweating it out in the “city heat,” realizing no
matter how hard I try it is not “a perfect world”
we live in. What would make my day, and other
fathers’ day, would be a present I could really use,
or at least understand without spending an entire
day reading the directions.
In spite of all this, I have discovered one thing;
being a father is its own reward. The Bible puts
fatherhood high on the list of important positions
in life.
David, the Psalmist, put his feelings about
being a father into familiar words to all who have
read the Bible. “Lo, children are an heritage of the
Lord: and the fruit of the womb is his reward. As
arrows are in the hand of a mighty man; so are
children of the youth. Happy is the man that hath
his quiver full of them: they shall not be ashamed,
but they shall speak with the enemies in the gate.”
(Psalm 127:3-5 KJV.)
This year, my advice is, whatever it costs, go
ahead and make dad’s day. He deserves it.
