NASA"s New Horizons image of Jupiter 1
These are Jupiter's massive storms,the Great Red Spot(GRS) and thedot just below it is the recently discovered Red Spot.Jr(RSJr)
NASA"s New Horizons image of Jupiter 2
This is an image of Jupiter's rings
NASA"s New Horizons image of Jupiter 3
This is an image of Jupiter's 4th largest moon,Europa,which has smooth icy surface and its diameter is slightly smaller than our Moon's
NASA"s New Horizons image of Jupiter 4
This is an image of Jupiter's 3rd largest moon,Io,which is the most active volcanic body in our Solar System due to the gravities of Jupiter and its other moons.It has a diameter slightly larger than our Moon's
NASA"s New Horizons image of Jupiter 5
This is an image of Jupiter's largest moon and the largest moonin our Solar System.Its diameter is about 470km more than Planet Mercury!
My issue in Astronomy
This the June issue
Pluto-Bound Spacecraft
Finally in 29 years!!NASA has launched a spacecraft to Pluto.

Featured image:Telescopic view of the crescent Moon(Can you see a crater or 2 of the Moon?)
Astrophotography Gallery:
Featured image:Telescopic view of Venus(Can you see a dim shadow of Venus's phrase?Because Venus is not at full phrase)
Astrophotography Gallery:
Featured Image:Telescopic view of Saturn(Can you see the gap between the planet and its rings?)
Astrophotography Gallery:
Featured image:Telescopic view of Jupiter(Can you see a dim dot just below the planet?Thats Ganymede,the largest Galilean satelite of Jupiter,largest moon of our solar system and larger than Mercury)
Astrophotography Gallery:
Featured Image:Gibbous Moon near dusk(evening)(Its Gibbous for sure,look carefully,is the Moon exactly round?)

Featured Image:Gibbous Moon(Can you see a small bright dot southwest of the Moon?Thats Jupiter)

Q:Why some astronomers think Jupiter is a failed star?
A:Because it is enormous,heavy and has a huge amount of gravitional force.
Q:Why did the IAU demoted Pluto as a dwarf planet?
A:It is because it did not cleared out parts of its orbit,which is now known as the Kuiper Belt,where larger icy objects are found.It was named after Dutch-born american astronomer Gerard Kuiper.However,this decision of the IAU will most probably reversed in 2009.I will tell you more if you ask me.
Q:Why does Neptune has the fastest winds in our Solar System than any other celestial object?
A:Scientists think its because Neptune probably has a very hot core.Neptune's average temperature is slightly lower than Uranus's average temperature,although it is 1.024 billion miles farther from the Sun than Uranus.If Earth did not have hot core,we probably wont have much storms and wont live in a warm environment!
Q:What created Saturn's rings?
A:Many theorists think that a great impact of a large comet or moon on another moon of Saturn were responsible in creating Saturn's very-visible-spectacular rings.But no one knows,unless NASA's Cassini,launched 1997,reached Saturn 2004,and still within Saturn's orbit,gets more with info on its rings.However,this is still consider one of the greatest mysteries in the Universe.
Q:Is there any celestial object in the Kuiper Belt that is larger than Pluto?
A:Yes.Eris(a.k.a Xena and 2003UB313).Discovered 2005 by astronomer Mike Brown,it is almost 10% larger than Pluto.It has a satelite,Dysnomia.It comes no closer than 38AU and goes no farther then 97AU.Eris takes 557 Earth years to orbit the Sun,more than twice as long Pluto's 247 Earth years.At the time of its discovery,it reached its aphelion.
