There are several different classes of supernovae. For example, Type II supernovae are associated with larger mass stars. The Sun will not terminate as a supernova, but may potentially evolve into a standard (or not) planetary nebula (see the Universe Today post “Astronomers Hint that our...
I eventually ended up with three classes: ConjunctionPair, for a single conjunction observed between two bodies on a single date; Conjunction, a collection of ConjunctionPairs covering as many bodies and dates as needed; and ConjunctionList, the list of all Conjunctions currently active. That let...

Being a very lazy student, he seldom takes ___ in all his classes. A. notices B. notes C. papers D. sights 8. ___ I could copy down the words on the blackboard, the teacher had wiped them off it. A. When B. Until C. Before D. Unless 9. The doctor said that she...
but looking to get into EAA. I have no clue how to understand what I need in terms of focal length and cameras to observe classes of DSOs like galaxies versus nebulae or clusters. If I choose to use my 10" dob on an equatorial platform, is that limiting me to image planets or other...
(high school and college) come to NRAO for an intense course in radio astronomy. The staff turn on the knowledge firehose and “really pour it on them”, as Mr. Sizemore puts it. They have classes during the day and then do research at night with the telescopes. He says it’s not ...
The SkySafari 5 app can display circles around classes of objects, including all the Messiers. This image shows the evening sky at 8 p.m. on March 27, 2017, the last evening of Messier Marathon season, when all 110 objects can be viewed in a single night. To do the marathon, you wi...
Several classes were developed in order to incorporate the methods defined in the application (Figure 2). Each button and menu was developed with its own graphic interface composed of inputs, parameters and output fields. The input and output field allows one to access the file through a ...
The separating hyperplane is obtained by seeking a projection which maximizes the distance between means of the two classes, and minimizes the inter-class variance. In the case of an N-class problem (N>2), several hyperplanes are used [477]. The LDA technique is very suitable for online ...
