In another method, astronomers watch for small dips in the amount of light from a star
as a planet passes in front of it.
Many astronomical bodies
such as planets, stars, and — in principle — black holes have magnetic fields.
Full planetary systems with up to 7 planets have been found as
well as planets in binary stars systems, making science fiction become a reality.
If that hypothesis is true, we could actually experience more extreme cold snaps, even
as the planet continues to warm.
The problem is that the proposal would mean defining all round objects smaller than
stars as planets.
This involves watching a star for dips in its
light as a planet passes between the star and the telescope.
Just as every planet has a gravity field, it is believed that every planet with an atmosphere is also surrounded by a weak electric field.
This supported orbital forcing of the ice ages and led to speculation that another ice age was inevitable
as the planet moved toward the corresponding configuration.
The telescope would examine each star to see how its light
changes as a planet passes in front of and behind it.
Just about every type of extreme weather event is becoming less frequent and less severe in recent
years as our planet continues its modest warming in the wake of the Little Ice Age.
Interestingly its target's
status as a planet changed while the spacecraft was already on its five billion mile journey.
By studying the dips in the star's light
as the planets transit, scientists were able to figure out the system's architecture.
They also independently verified more than 700 additional planet signals that had already been
confirmed as planets by other methods.
As our planet spins, the sun appears to move across the sky — but really we're the ones who are moving!
Both telescopes are designed to spot the tiny dips in a star's
brightness as a planet passes between the telescope and the star.
Global ice cover
acts as the planet's thermostat, regulating temperature by reflecting sunlight back into space.
The amount of rain that tropical storms bring is also expected to
increase as the planet warms, because of increasing water vapour.
The warming oceans could start to return more carbon dioxide to the
atmosphere as the planet warms, according to new research.
The eruptions were powerful enough to affect the global
climate as the planet was recovering from an ice age.
And this is a serious security problem that we as a community and also
as a planet need to address going forward.
Seeing as our planet's fossil resources are limited, researchers are looking for new methods for the production of certain substances, which are not dependent on mineral oil.
During 24 Hours of Reality, you heard 24 presenters say we expect more floods and droughts around the
world as the planet warms.
After all, we spend over 3 billion hours a
week as a planet playing video games.
The nature and scope of the problems we're likely to face over the next few years will require us to work
together as a planet otherwise we'll face ruin.
The simulations also suggest that the removal of excess carbon dioxide from the atmosphere by natural processes on land and in the ocean will become less
efficient as the planet warms.
For example, soil is second only to
oceans as the planet's largest carbon sink, while agriculture and land use changes represent the second largest source of greenhouse gas emissions.
In the absence of giant planets, water delivery could happen
naturally as planets pull in debris from different parts of the solar system.
