What If other planets replaced our Moon : Or Different Stars : Incredible Roscosmos video

[Cidersomerset]

Have you wondered what it would be like to look at a distant star from a planet
in its solar system or if we had a different satellite orbiting our own Earth.

Well so has someone else ....LOL....some lovely vids.....

would look in the sky.

You would maybe love the video game GOlden Sun and also the book Cradle of Saturn :)

A visit from Saturn: What if Saturn flew past the Earth

Trivia:

Saturn's rings were created using Voyager data and Cassini Data, and tables
from the IAU, and nasa Interestingly enough, the voyager data and Cassini
data did Not completely match each other, More interestingly the differences
between the two data sets were not consistent along the ring, specifically the
small Gaps along the rings are inconsistent between voyager and cassini.
there are 3 conclusions i can reach from this,
1, the data is simply not perfectly accurate,
2, I interpreted the data incorrectly,
3, the Rings have actually changed a bit between voyager and cassini.

Distant exoplanet hosts giant ring systemPaul Rincon

Ring system - artist's impression How the ring system might look up close

Astronomers say they have discovered a planet with a gigantic ring system
that is 200 times larger than that around Saturn.

It is the first such structure detected around a planet beyond our Solar System.

The researchers say there are probably more than 30 rings, each measuring
tens of millions of kilometres in diameter.

The findings by a Dutch-US team are to be published in the Astrophysical Journal.

Gaps detected in the ring system also suggest that some of the material may
already have coalesced to form moons. This phenomenon can be seen at
work in Saturn's rings today.

"You could think of it as kind of a super Saturn," said Prof Eric Mamajek, from the
University of Rochester in the US.

The rings were found in data gathered by the SuperWASP observatory, which
can detect exoplanets as they cross in front of their parent stars, causing the
light from them to dim.In this case, the astronomers saw a complex series of
deep eclipses lasting for 56 days. They think this is caused by a planet with a
giant ring system blocking out light as it passes in front of the star J1407.

"The light curve from end-to-end took about two months, but we could see
very rapid changes in the space of one night," lead author Dr Matthew
Kenworthy, from the University of Leiden, the Netherlands, told BBC News.

"Over a time of half an hour, the star can dim by 30 or 40%."

If Saturn's rings were the same size as those around J1407b, they would be
easily visible from Earth at night and would be many times larger than a full Moon.

Artist impression of rings in sky This artist's impression shows how the ring
system might look in our night sky if they were put around Saturn
Other possibilities, such as a planet-forming disc (the swirling mass of dust
and gas from which planets form around a star) can be ruled out. A disc,
says Dr Kenworthy, would produce much smoother changes in the light
curve of J1407.Last year, the astronomers tried to find the planet itself,
but were not able to observe it.

"We threw the kitchen sink at this, we tried every single technique that
we could think of," said Dr Kenworthy.

"But the lack of a detection means it has to be substellar, and the only
thing that could hold these rings in place is a planet."

The team thinks that the planet itself is most likely a gas giant like Jupiter,
but between 10 and 40 times as massive as that planet.

The distant ringworld, named J1407b, might also offer a glimpse - on a
much larger scale - of the process that led to the formation of moons
around gas giants in our own Solar System.

"The planetary science community has theorised for decades that planets
like Jupiter and Saturn would have had, at an early stage, disks around
them that then led to the formation of satellites," said Prof Mamajek.

The astronomers found at least one clean gap in the ring structure.

"One obvious explanation is that a satellite formed and carved out this
gap," said Dr Kenworthy. "The mass of the satellite could be between
that of Earth and Mars."

The researchers are encouraging amateur astronomers to help monitor
J1407, which would help detect the next eclipse of the rings. Observations
of J1407 can be reported to the American Association of Variable Star Observers (AAVSO).
