Observing Asteroids

Although many asteroids are visible with amateur equipment, and at least one can be seen with the unaided eye, the size of the companion moons make them too small for amateur observers to spot.

The first asteroid moon was not discovered until 1993, and this was by the spacecraft Galileo that flew past the asteroid belt. It was not until images taken in 2004 that the asteroid Sylvia was discovered to have two moons, followed by Eugenia and its two moons. This discovery required the use of the telescope at the European Southern Observatory in Chile.

An asteroid with three or more moons has yet to be discovered.

Main Belt Asteroids with Moons

Of the many asteroids that have satellites, few are given proper names. Most minor planet moons are classified by the year they were found. Some of the better known asteroid and moon pairs with names are

Ida and its moon Dactyl
Kalliope and its moon Linus
Sylvia and its moons Remus and Romulus
Kleopatra and its moons Alexhelios and Cleoselene
Eugenia and its moons Petit-Prince and the less charmingly named S/2004 (45) 1

Naming a supernova

The naming of supernovas is determined by the International Astronomical Union (IAU). Once a supernova is discovered it is reported to the IAU which then sends out a circular with the name it assigns it. Naming is done by the year of the discovery, immediately followed by a one or two-letter designation.The discovery of the recent supernova was soon verified by astronomers in Canada and the U.S. Once verified it was reported to the IAU's Central Bureau for Astronomical Telegrams. As far as discoveries go this is Kathryn's first. However, her father has seven under his belt while their friend David Lane has four.

What is a Supernova?

Supernovae are stellar explosions in which a dieing star ends its life in a colossal explosion. Stars that are only several times more massive than the Sun end up as supernovae. The amount of radiation released in a supernova explosion briefly outshines an entire galaxy.

Supernovae were observed as early as 185 AD by Chinese astronomers. SN 1006 was the brightest recorded supernova observed in the 10th century by Chinese and Islamic astronomers. It was so bright that for a brief period it was visible during the day. Supernovae are somewhat rare events and occur only about once every 50 years in our Milky Way galaxy. Many galaxies are therefore constantly monitored to look for any signs of new supernovae. Supernovae form the "stuff of life" as all the known chemical elements present on a planet are initially formed within the dense hot core of the star.

What you Should Wear

When it comes to actually picking out the jewelry, you have a lot of different options. What you should wear is going to depend on what your dress looks like. Not only is the color going to make a difference, but also the style. So, you will want to look at certain jewelry styles with strapless dresses, other styles with cocktail dresses, and you may need something completely different for short dresses that have straps. Trying on the jewelry will tell you what styles you want for the particular dresses that you are looking at.

Styles of Jewelry Depending on what your dresses look like will depend on the style of jewelry that you wear. For people that are wearing strapless dresses, they may want to have some jewelry that stands out a little bit more. For cocktail dresses with sleeves or straps, you may not need to have quite as much that stands out. Other people really like to go over the top and get lots of fancy, shiny jewelry that looks great. With all kinds of styles out there, don’t settle on the first piece of jewelry that you find, be sure that you are shopping for all your options and looking for ones that truly fit you and your dress.
