This ability to survive in extreme conditions «might be important when we consider the habitability
of other bodies in our solar system or beyond,» says astrobiologist Gerda Horneck of the German Aerospace Center.

Exploding stars have shaped every part
of our world: They created the iron and
other heavy elements
in our
bodies, and one
of them may have provided the shove that initiated the formation
of our
solar system.
Though that remains to be determined, Batygin suggests that the planet may have been ejected from the neighborhood
of the gas giants by Jupiter, or perhaps may have been influenced by the gravitational pull
of other stellar
bodies in the
solar system's extreme past.
Titan, the largest
of Saturn's more than 60 moons, is the
other body in our
solar system with a nitrogen - rich atmosphere that resembles ours.
Poor Pluto is crowded by thousands
of other icy
bodies in the outer
solar system, some bigger than Pluto itself, so it fails the test.
For decades Pluto, later joined by its moon Charon, had a wide swath to itself on astronomers» plots
of the
solar system — no
other bodies were known to dwell beyond Neptune
in the long - hypothesized debris field known as the Kuiper Belt.
The work suggests that frigid Titan actually resembles Earth
in some key ways, such as seasonal weather, and it also hints at the possibility that the moon holds vast underground reservoirs
of liquid hydrocarbons — a first for any
other body in the
solar system.
So, he says, is Europa, commonly known as a moon
of Jupiter, and so is the Earth's moon, and so are more than 100
other celestial
bodies in our
solar system that are denied this status under the prevailing definition
of «planet.»
Titan is the only
other body in the
solar system to show evidence
of an active weather cycle, where liquid evaporates from lakes to form clouds, and rains back down to the surface, forming rivers and channels.
Understanding the origin and fate
of methane on these
bodies will provide crucial clues to the processes that shape the formation, evolution and habitability
of terrestrial worlds
in this
solar system and possibly
in others.
Outside
of Earth, Titan is the only
other planetary
body in the
solar system with actively flowing rivers, though they're fed by liquid methane instead
of water.
As impact glass is a ubiquitous substrate on rocky
bodies throughout the
Solar System and likely common on the early Earth, the preservation
of biological activity
in impact glass has significant astrobiological implications for life on early Earth as well as for the search for life on
other planets.
Observations
of the planets, satellites, and small
bodies in the
Solar system provide indispensable information about planet formation and evolution processes that remain unattainable for
other planetary
systems.
Titan is the second largest moon
in the
solar system, after Jupiter's moon Ganymede, and it's sometimes called a planet - like moon: It's the only
other world
in our neighborhood to feature stable
bodies of liquid on its surface, and it has a thick atmosphere made mostly
of nitrogen.
These attributes all have to be understood
in the context
of what we know about the Earth, Moon and
other bodies of our
solar system.
Meanwhile, protoplanets that have avoided collisions may become natural satellites
of planets through a process
of gravitational capture, or remain
in belts
of other objects to become either dwarf planets or small
solar system bodies.
It speaks to the very heart
of trying to understand how life may have evolved not just on earth but on
other terrestrial
bodies both
in our own
solar system and indeed around
other stars that have planets that lie
in the so - called «habitable zone» (where liquid water can exist on the surface).
The scope
of COSPAR comprises space studies
of the Earth's surface, meteorology and climate; space studies
of the Earth - Moon
system and
other bodies of the
solar system, including the search for evidence
of life
in the
solar system; study
of planetary atmospheres including those
of the ever - expanding inventory
of exoplanets; space plasmas
in the
solar system; research
in astrophysics from space; life sciences as related to space; materials sciences
in space; and fundamental physics
in space.
Other solar system bodies have stratospheres, too; methane is responsible for heating
in the stratospheres
of Jupiter and Saturn's moon Titan, for example.
This works at every level: our atoms working
in harmony to create and keep our cells whole, our cells coming into harmony to create our
bodies, our
body's ability to come into harmony with
other bodies to create communities and cultures, our culture's ability to get along and stop fighting
in order to create a world
of people living
in harmony as one planet, the plants creating the harmony that hold our
solar system together, and on and on.
It contains comprehensive sections on: - The Sun, Planets, and Dwarf Planets; - Information about their moons; -

of Discovery; The resource is designed to be printed onto A3, and is provided as both a PDF and a Word version (so that you can edit if you want to).
The
other is that you are building on top
of the common pool, which has provided you with a kick start - nowadays people learn
in school about Pythagoras, the
solar system, the human
body, chemistry etc, all
of which have been «exceptional» or even cabal secrets once, but have flown back to the common pool for
others and more people to build on than ever.

The shift is believed to result from a complex interplay with the gravitational influences
of Venus and Jupiter, along with
other bodies in the
Solar System as they all whirl around the Sun like a set
of gyrating hula - hoops, sometimes closer to one another, sometimes further.
But as for the tilt, Batygin suggests that the planet may have been kicked out
of the gas giants» neighborhood by Jupiter, or may have been pulled by
other stellar
bodies in the
solar system's distant past.
