Question by Stefan: Could you tell me some things about Solar and/or lunar ECLIPSE ? Thank you?
I need some interesting facts about these two, if you know only about one of those, please answer, also if you know where to download videos of SOLAR ECLIPSE, LUNAR ECLIPSE and universe, especially if it's about the sun or about the moon.
Oh and if you know anything about what people used to believe in when they didn't know what happened and are there any drawings ( like in caves ) that are showing them being scared or something ?

NASA's Hubble harvests distant solar system objects

NASA's Hubble harvests distant solar system objects
Beyond the orbit of Neptune reside countless icy rocks known as trans-Neptunian objects (TNOs). One of the biggest, Pluto, is classified as a dwarf planet. The region also supplies us with comets such as famous Comet Halley. Most TNOs are small and receive little sunlight, making them faint and difficult to spot.
Now, astronomers using clever techniques to cull the data archives of NASA's Hubble Space Telescope have added 14 new TNOs to the catalog. Their method promises to turn up hundreds more.
"Trans-Neptunian objects interest us because they are building blocks left over from the formation of the solar system," explained lead author Cesar Fuentes, formerly with the Harvard-Smithsonian Center for Astrophysics and now at Northern Arizona University.
As TNOs slowly orbit the sun, they move against the starry background, appearing as streaks of light in time exposure photographs. The team developed software to analyze hundreds of Hubble images hunting for such streaks. After promising candidates were flagged, the images were visually examined to confirm or refute each discovery.
Most TNOs are located near the ecliptic -- a line in the sky marking the plane of the solar system manufacturer (since the solar system formed from a disk of material). Therefore, the team searched within 5 degrees of the ecliptic to increase their chance of success.
They found 14 objects, including one binary (two TNOs orbiting each other like a miniature Pluto-Charon solar system supplier). All were very faint, with most measuring magnitude 25-27 (more than 100 million times fainter than objects visible to the unaided eye).
By measuring their motion across the sky, astronomers calculated an orbit and distance for each object. Combining the distance and brightness (plus an assumed albedo or reflectivity), they then estimated the size. The newfound TNOs range from 25 to 60 miles (40-100 km) across.
Unlike planets, which tend to have very flat orbits (known as low inclination), some TNOs have orbits significantly tilted from the ecliptic (high inclination). The team examined the size distribution of TNOs with low- versus high-inclination orbits to gain clues about how the population has evolved over the past 4.5 billion years.
Generally, smaller trans-Neptunian objects are the shattered remains of bigger TNOs. Over billions of years, these objects solar system supplier smack together, grinding each other down. The team found that the size distribution of TNOs with low- versus high-inclination orbits is about the same as objects get fainter and smaller. Therefore, both populations (low and high inclination) have similar collisional histories.
This initial study examined only one-third of a square degree of the sky, meaning that there is much more area to survey. Hundreds of additional TNOs may lurk in the Hubble archives at higher ecliptic latitudes. Fuentes and his colleagues intend to continue their search.
"We have proven our ability to detect and characterize TNOs even with data intended for completely different purposes," Fuentes said.

Free astronomy software that lets me create my own theoretical solar system?
by Velo Steve
Question by : Free astronomy software that lets me create my own theoretical solar system?
And then calculate events such as solar eclipses and moon phases? Would anyone know of a program like that or at least a way to try and find a program like that?
Additional Details
I need something that will allow for the formulation of a calender for the various planets, which includes the lunar phases of various moons for each planet and will allow me to view them in orbit at any set date on the solar calender created for the system. I also need one that does most of the advanced physics and mathematics for me as I am not skilled or talented in those areas. Think something for the education of an average high school student or general layperson.

Answer by Dr WhoI am the only one in my high school to take an independent study in astronomy. At college, I took the basic astronomy class and was a lab assistant at the same time which had plenty of students doing a double take. Also had to give a lecture because the professor was ill and had a physics professor assisting me. It turned out that he was hiding nearby. I have not heard of a program for a make believe planetary system. Google Earth has extras like zooming in on the Moon/Mars/etc. Go surfing.

I would just call up astronomy departments at universities and ask this question to the professors. Track down an observatory. They would love to talk your ear off on it.
