... Properties of Dust Grains in Planetary Nebulae - I. The Ionized Region of NGC 6445 . ... Based on this model, we show from depletions in the gas phase elements that little grain destruction can have occurred in the ionized region of NGC 6445. ... The most likely conclusion is that grains are residing inside the ionized region of NGC 6445 and that the low temperature and flux of the grain emission are caused by the low luminosity of the central star and the low optical depth of the grains. ...

. Two neighboring stars did not pass each other without incident early in their lives. More than 4 billion years ago, our Sun got into a property battle with a wandering star. Each star ran off with some of the other's dust and debris. A mixture of indigenous and captured material resulted from the stellar squabble.

... Planets . ... Exoplanets . ... After the discovery of powerful telescopes we were able to see further into our Solar System and discover many distant objects and dwarf planets.€а However within the last 16 years astronomers have started to dedicate much more time to the search of other worlds in orbit around other stars beyond the realm of our Solar System. ... However the closest star with a known exoplanet is the star Epsilon Eridani which is a mere 10.4 light years away from planet Earth. ...

... Bad Astronomy . ... The Nine Planets . ... That means that for a short time you can actually see the tiny planet in silhouette against the disk of the Sun. ... As little as ten years ago, we didn't know if there were any planets orbiting other stars or not. ... They have been detected by their gravitational tugging of their star; as they orbit, the star moves in a little circle as the planet makes a bigger one. ... And it comes the same week we see one of our own planets pass in front of our own...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...
