How Do Astronomers Name Celestial Objects? There are thousands upon thousands of celestial objects, discovered by hundreds of different individuals over the course of centuries.

How Do Astronomers Name Celestial Objects?

While many of them have easy to remember names—like the Orion Nebula, the Lagoon Nebula, the Butterfly Nebula and the Hourglass Nebula—most have designations that are anything but. Moreover, the memorable names aren’t always recognized by the International Astronomical Union (IAU): the organization with the sole authority to give names to celestial bodies. Even they tend to go with names that are mixtures of seemingly random characters, which aren’t really random at all. In astronomy, names aren’t just for reference. Rather, each designation is meant to convey important information about the object itself, and more often than not, objects are appointed with more than one name.

What's a Planet? There's a Test (and Pluto Flunked it) Nine years ago, the International Astronomical Union established new criteria for determining what classifies as a “planet,” a controversial move that officially (but not in spirit) stripped Pluto’s status as the solar system’s ninth planet.

Left undecided was what to do about all the so-called planets being discovered outside the solar system, a number that now approaches 5,000.

What's shakin. An earthquake is a sudden release of stored energy.

what's shakin

Earthquakes occur when slow but powerful tectonic forces cause stress to build up in the Earth’s crust. When the stresses get large enough, slippage is triggered along fractures in the rock known as faults. The sudden slipping motion along a fault causes vibrations known as seismic waves to form and travel away from the zone of slippage. Measure Distance on a Map. The measure distance tool is a simple way of find the distance between two points on a map.

The Language of Maps Kids Should Know. Though in the age of iPhones and GPSs we seem to be losing paper maps, I still love exploring maps, and believe kids need to learn map skills, and develop their geography awareness. Because of this I have many activities on Kid World Citizen to help parents and teachers teach children about maps. Kids not only can learn to read them, but to recognize their components and build their own maps. I was recently asked for a list of vocabulary or concepts of maps kids should learn.
