Visit SOHO Explore! to learn more about the Sun and how it works. This allows us to see streamers and radial bands in the corona that would otherwise be invisible. The Large Angle Spectrometric Coronagraph captures activity in the solar corona by blocking out the overwhelming light from the Sun itself so the delicate corona can be seen. The Michelson Doppler Imager (MDI) captures data that provides us with a view of current sunspot activity, such as this magnetogram image. The hotter the temperature, the higher in the solar atmosphere we see. These wavelengths correspond to different surface temperatures on the Sun, from 60,000 degrees Kelvin to over 2 million degrees Kelvin. Images from the Extreme ultraviolet Imaging Telescope (EIT) are taken in several different wavelengths of ultraviolet light (304, 171, 284, and 195 angstroms). All of these images are taken every few minutes, so you can follow activity on the Sun in near-real time. The Solar and Heliospheric Observatory web site provides images of the Sun in many different forms. In the dark and gloomy days of winter, is there still a way to engage in observational astronomy? Did you know you can observe the Sun when it’s cloudy? Did you know you can observe the entire night sky in the daytime? What about observing the Moon when it’s not visible in the night sky? These are all possible with some help from your computer and the Internet. Images from EIT at 195 and 304 angstroms, MDI Magnetogram, and LASCO C3. New ones are added from one day to the next. These are just a few of the Astronomy Apps that are available at the Apple iTune Store. NASA App: This App takes data from NASA's Internet Website via a WIFI Connection and gives you instant access to the latest NASA News, Photos and Videos. Mars Globe: Very similar to Moon Globe, this App is for Mars, based on NASA spacecraft photos, with a “3D Photo Quality” map. Moon Globe: Very similar to “The Virtual Moon Globe”, this App will help you identify or locate lunar features with a “3D Photo Quality” map. Iridium Flares: This free App will predict when, where, and how bright Iridium Flares will occur. How many times have you been out at night, and wondered what that bright, moving light was. This App will let you know when a Satellite such as the International Space Station will appear overhead up to a year in advance. The orbits are projected on a image of the constellations in the night sky in real time. Pocket Sat 3: This is a free App that will predict the passage, or identify artificial satellites as the pass overhead. This App will also show the brighter comets and asteroids and identify and plot passing artificial satellites. Sky Voyager: This is a very good Planetarium program that very accurately shows the locations of Deep Sky Objects, planets, the moon, stars and constellations, very similar to “Stellarium” or other planetarium software programs for computers. The following are a few Astronomy Apps that I have found in the Apple iTunes Store that are very useful and of very high quality: If you can think of something that you want your Apple device to do, most likely, “There Is An App For That”, including Astronomy. These Apps are usually very cheap, not more that a couple of bucks, or free to download. Other devices, such as the Ipod Touch are not cell phones, but can access the internet through a WIFI network connection, just like a desktop or a laptop computer in your home, a coffee shop or an airport.Īpple developed the iTunes Store website to sell music, movies and software to iPhone and iPod owners.Īpple and independent computer programmers write software applications (Apps) that will do about anything imaginable. Smart Phones, such as the Apple iPhone or the Motorola Droid can access the Internet via a 3G network, which works the same way as making a Cell Phone call, i.e., the internet data is sent and received via a cell phone signal to the nearest cell tower. Most use a Flash Hard Drive for storage and have rechargeable lithium batteries. The original intent was to use it to listen to Music (MP3s), watch movies, and access the internet on the go.īasically, an iPod Touch and most of the other “Smart Phones” are miniature computers. I recently purchased a 3rd Generation 64 Gigabyte Apple iPod Touch.
