#Earth's Water Is Older Than The Sun Since water is one of the vital ingredients for life On earth scientists want to know how it got here.
One theory is that the water in our solar system was created in the chemical afterbirth of the Sun
. If that were the case it would suggest that water might only be common around certain stars that form in certain ways.#
#But a new study published today in Science suggests that at least some of Earth s water actually existed before the Sun was born
#If water in the early Solar system was inherited primarily as ice from interstellar space then it is likely that similar ices

#Solar activity is linked NOT to global warming: Sunspot theory of climate change is the result of an ancient error in the data The theory that solar activity is linked to rising global temperatures has been cast into doubt after scientists corrected an ancient error in the calculations.
Until now, the general consensus was that solar activity-in particular sunspots -and temperatures have been trending upwards since the harsh winters of the 17th century when the spots were thought to have been at a low.
But when the error was corrected, the records show there was no such culmination in solar activity in the late 20th century,
suggesting climate change cannot be plotted using this sunspots method. Scroll down for video In fact, solar activity appears to have remained relatively stable
since the 1700s while global temperatures have fluctuated. According to the previous calculations, harsh winters in the 17th and 18th centuries corresponded with low numbers of sunspots,
which suggested a link between climate and solar activity. This period is known as the Maunder Minimum,
and solar activity is said to have peaked in the late 20th century, sometimes called the Modern Grand Maximum, around the time of the Industrial revolution.
known as the Wolf Sunset Number and the Group Sunspot Number, showed different levels of solar activity before 1885,
The Group Sunspot Number had a major error that showed a gradual increase in solar activity for the past 300 years.
we then consider the implications on our knowledge of solar activity over the last 400 years.''
''The newly corrected series clearly indicates a progressive decline of solar activity before the onset of the Maunder Minimum,
solar activity had returned already to levels equivalent to those observed in recent solar cycles in the 20th century.'
'And the trends recorded are over much longer periods than the well known 11-year cycle of the sun,

Exospheres are the most common type of atmosphere in our solar system, so scientists are keen to learn more about them. t's critical to learn about the lunar exosphere before sustained human exploration substantially alters it,
Most of the moon's exosphere comes from the solar wind, which is a thin stream of electrically conducting gas blown from the surface of the sun into space at around a million miles per hour.
Most of the solar wind is hydrogen and helium but it contains many other elements in small quantities,
including neon. All these elements impact the moon, but only helium, neon, and argon are volatile enough to be returned back to space.
While most of the lunar exosphere comes from the solar wind, the readings showed that some gas comes from lunar rocks.

trackers can be used to allow the panels to follow the sun throughout daylight hours. The advantages of trackers are dramatic,
