Amazing New Hubble Pics
Author: Anne Noonan
New Hubble pics - how exciting! The latest of the new Hubble pics is of a black hole, which they've captioned as being in need of a home.

To get these new Hubble pics a team of astronomers, all from Europe, combined the power of the Hubble Space Telescope with that of the VLT (Very Large Telescope at the European Southern Observatory (ESO) in Cerro Paranal.

The new Hubble telescope pics are of a bright quasar that has no discernible host galaxy. The new pics show several quasars, strong radiation sources. The astronomers honed in on these quasars to study them by way of the Hubble because they know that quasars are often associated with active black holes. Only one of the many quasars they found delivered a black hole without a galaxy. Thus the new Hubble telescope pics.

Other new pics show the other quasars that these European astronomers found. In one you can clearly see the black hole's host galaxy with its large spiraling tendrils.

In the past ten years the problem getting new Hubble telescope pics of black holes has been that the quasar shines so much more brilliantly than the host galaxy that observers can't always see, or get new pics of, the black hole and its galaxy. This problem has been resolved now so new Hubble telescope pics of host galaxies are possible.

With the recent observation of 20 quasars, 19 were found to have host galaxies. One did not. What this means is that if the host galaxy really does exist it has to be no more than one sixth the brightness of traditional host galaxies, or have a radius that is at least 20 times smaller than most host galaxies. New Hubble telescope pics of this find are being studied now.

Galileo Telescope
Author: George Royal -
One telescope maker that has been making a name for itself over the last few years is Galileo Telescope. This company, based in India, prides itself on offering excellent telescopes and one-on-one service with knowledgeable people who use the telescopes themselves. This allows Galileo Telescope to not only offer excellent optical equipment, but also excellent customer service.

Begun in India in 1989, Galileo Telescope began its life by offering telescopes for Indian amateur astronomers who need a quality telescope for their stargazing needs. Determined to set themselves apart from the rest of the market, Galileo Telescope came out with an 8-inch telescope, which is rather large by Indian standards. And, even more, Galileo's first telescope was easy to use, allowing even novice astronomers to learn it quickly.

With this success under their belts, Galileo Telescope continued to innovate. First, they developed a reliable, easy to operate mount that allowed amateurs to have a stable platform for their telescopes. Then they stretched out to create larger telescopes for deeper explorations of space, while also creating portable models that made for easier carrying and transportation.

Additionally, Galileo Telescope is the only Indian company to offer its customers Dobsonian telescopes. This large, rugged and reliable design is well known and familiar to amateur astronomers, as it makes large-aperture telescopes an affordable option for the backyard skywatcher. While made from a simple, Newtonian design, its simplicity allows it to be a very reliable and very powerful option for people who want to peer into the vastness of space.

For those who want the challenge of building their own telescopes, Galileo Telescope also offers an excellent selection of lenses, mirrors, eyepieces that will allow amateurs to create a telescope to their own specifications and give themselves the view that they uniquely desire. And, for the nervous novices who want a little more help with their telescope building adventures, Galileo also offers telescope kits that will allow them to build their own telescope and learn the inner workings of optical instruments in a less risky situation.

In addition to their standard line of Dobsonian telescopes, Galileo Telescope also offers a wide range of equipment for a variety of needs. Whether it might be a spotting scope, binoculars, a tripod or a refracting telescope, the people at Galileo Telescope are always eager to use their expertise to stretch themselves into new areas. And, as Galileo expands their reach into new realms, rest assured that they are just as committed to crafting some of the finest optics available.

For people who want a telescope that has been created, tried and tested by people who use the optics they offer, Galileo Telescope is an excellent name to trust. They pride themselves on designing and creating excellent telescopes that they are willing to stand behind and support. And with their one-on-one support, they will be able to help anyone who has questions or needs assistance with their products. All of which makes Galileo Telescope a company that amateur astronomers can turn to when they want to turn their eyes to the heavens.

What Are Telescopes?
Author: Jason Adams -
Telescopes act as windows to the universe. It is with the help of telescopes that we can study the solar system and view the conjunctions of stars. Not just that, the various planets, galaxies, satellites and asteroids that we get to see only in the books and magazines are made more familiar to us via the telescopes. They act as barrier- breaking instruments between the human beings and the outer space. The universe is no more a mystery to us that exists beyond our reach and we owe it all to the telescopes.

The modern day telescopes bring with them a wide array of accessories and it is with the aid of these accessories that it becomes much more easier to successfully put the telescopes into proper use. Let us see what are the important accessories that go well and are a "must-have" for most telescope users: -

Filters- These are very essential for telescope users because they reduce the glare on the eyepiece and scatter the light thereby making it less strenuous for us to view distant objects.

Eyepiece- this is a very important piece of equipment and its absence can render a telescope useless. Eyepieces come in a variety of sizes and if you add more than one eyepiece to your telescopes then you can have the pleasure of viewing even the tiniest and distant objects with clarity.

Mounts- Mounts are the stands for telescopes. It is a mount on which the telescope rests. Since a telescope wont function favorably in vibrations therefore you should ensure that it is placed on a stable mount.

Barlow lens- A Barlow lens helps in the magnification of telescopes. These lenses are available in different sizes and we must be careful in choosing the size that best fits the eyepiece.

There are two main types of telescopes, the refractor (Galileo) telescopes and the reflector (Newton) telescopes. The refractor telescope uses an objective lens that bends the light towards the eyepiece. While the reflector telescope uses a mirror, which collects the light and then directs it towards the eyepiece.

Though both the refractors as well as the reflector telescopes are easily available in the market we should take the following points into consideration before buying a telescope.

Do not get impressed by the magnification of the telescopes. This is because magnification alone is of no use if it just produces large but hazy images.

Aperture- This is the most important factor while deciding on a telescope. Aperture is the opening that collects light so its important to choose a telescope with a larger aperture that will ensure a clearer and a more detailed image quality.

Resolution- This enables the telescopes to produce a more detailed image. So always opt for a telescope, which has a higher resolution. Moreover since resolution is also determined by the aperture, therefore the larger the aperture the better the resolution.

Focal length- The distance between the optical center of the lens or the mirror and the optical center of the eyepiece is known as the focal length. The focal length is what determines the magnification in telescopes. Larger focal lengths imply more magnification.

If we are careful about remembering the above points then it wont take us long to choose a telescope the next time we want to buy one for ourselves.
