Recent astronomy articles appear all over the Internet and in magazines dedicated to the science and the hobby.  When new images are taken, people write about it.  New space missions result in articles.  There is a constant stream of conversation.  Here’s just some of the most recent astronomy articles.

Bumpy space dust, of all things, generated many recent astronomy articles.  Why so much interest?  Scientists know that hydrogen is the universe’s basic building block.  But hydrogen has to bond to form the larger molecules observed in the universe.  Because of the cold in space, hydrogen needs a little push.  It could be the bumpy surface of dust that helps in that process.  Imagine that.

One of Saturn’s moons is called the “Death Star.”  It’s a huge crater that makes it look like the movie menace.  Cassini passed near this moon, news of which prompted many recent astronomy articles.  Some stunning images and a lot of new data resulted.  It was a popular story.  One hope scientists have is that this new data will reveal information about the number of crater creating objects fly through the Saturn system.  This can give new insight into how busy our solar system is as far as impact capable objects, as well as reveal the true extent of how other planets, like Saturn, serve as object scrubbers in our solar system.

It’s long been known that dark matter exists in the universe.  It helps the universe expand, but it’s not clear how it does this.  In 2008 a number of the recent astronomy articles were dedicated to the search for and analysis of dark matter.  SNAP, the SuperNova/Acceleration Probe, was planned to help solve dark matter by examining many distant supernovae.  70% of the universe’s matter is dark matter so this is important work.

Before becoming a sun, our little yellow sun was just a proto-sun.  Emissions of heat and light as well as solar winds from this proto-sun have long been a matter of contention.  Recent astronomy articles answer this question with a resounding yes.  New techniques have revealed that the proto-sun had a particle rich solar wind along with light and heat.  These emissions helped form life on Earth even before the sun was a sun.

The Internet is a great source for learning about recent astronomy articles.

When looking to purchase web hosting for the first time there are a few things you need to weigh out. Free hosting is going to be pushed out of the way for now.  Free hosting can be a good option for many but paid hosting is much better overall-Using free hosting can be okay but with the small costs paid hosting is a better option.

Looking at web hosting you need to know what your web site will be providing.  Such as if you are going to work with proxies you must back sure the host will allow them.  With proxies you need to get a hosting company specifically for them.  With most other sites you will be good with any type of hosts. It is important to have an idea on how much traffic you will bring in at first. Many times you will not bring in a lot of traffic at first but some can so that is a big issue with web hosting.  Next how much space do you need from your web hosting.  Is your site going to be a blog?  Uploading plenty of pictures or providing software to download?  After you figure out traffic and space then you can estimate the website you are going need-Once you have decided on these amounts space and traffic you can figure out your bandwidth.  If you are not sure you will probably get by with a minimum account. 

When these questions are answered you will have one more question to ask. How many domains do you believe you will host at the same place.  Most web hosting companies will allow you to have unlimited domains but some lower accounts will put a limit on the amount.  After you have figured this all out you can find the best web hosting for your needs.

It is a day written in gold for all Indians. An Indian shooter has reached the finals of an Olympic. Every Indian is eagerly awaiting the finals to begin, to encourage, to share, the joy of watching an Indian winning Olympic gold medal for the first time in history. His success will be the headline news in India. It will probably make the front-page of all Indian new papers both regional and national. The editors have a choice on how to cover the match. They can rely on various new-agencies and/or they can send their own sports reporter and a staff photographer to cover the event live. The editors decide to fly out their own team. The reporters and photographers arrive in Beijing well ahead of the event. This enables them to prepare reports on the finalists to build-up interest in the competition. The match is due to start. The results will be out soon. The reporters and photographers have to send their reports and photographs within the deadline prescribed. The press box is busy. The reporters can type their copy into their portable word processor. Their laptop is a remote terminal of their papers main computer. When their stories are complete, the reporters simply attaches the audio coupler or adapter to the telephones, key the number of their newspaper, and the text is sent along the wires directly into their computers thousands of kilometers away. A 2000-word article is sent in less than a minute. The final of the shooting competition ends in a brilliant and sensational victory for the Indian. In addition to their reports already sent, the reporters will now interview the winner. The photographers request other international news agencies for picture-transmission equipment. The photographers processes their films and then feeds the best negative into a transmitter. This dispatches the image along a telephone line which emerges as high-quality duplicate negatives back in their respective newspaper computers. After interviewing the shooter, the reporters prepare their final copy, rearranging and correcting the text on the laptop VDU (visual display unit) screen and transmits their follow-up article. This gives more details and visuals than is found in the news-breaking television, radio, and print reports. This final report contains additional information on the champion’s future prospects, his family background, his other interests, and an account of his lifestyle. Front-page Article The respective sports editors at various newspaper offices access the report on their desktop screen. As per their discussions earlier at an editorial meeting, the report will be the sports page lead. There will also be a front-page news item adapted from the main article which also the editor can access on his own screen. The subeditor then checks, corrects, and adjusts it to fit the space allocated on the page by the sports editor. The subeditor can access on his screen an image of the whole page showing all the other stories, headlines, and pictures plus advertisements that have already been set. The subeditor knows exactly what space there is, as the editor has already chosen the picture that will illustrate the article. The draft is now finally edited on screen to fit the space and an apt headline written to fit the picture and article. If needed, a picture caption is also written by the subeditor. Now all copy for the first edition must be set in type to meet the deadline. This is done up with all the other copy for conversion into type by a high-speed phototypesetting machine. A 2000-word article is typeset in less than a minute. The typesetter produces a ‘bromide’ (a print of the type on photographic paper) for positioning on the page according to the approved layout. This can be done by using the computer. There are many newspapers that still prefer to physically cut up the bromides and paste them into position on a page-size card. The subeditor rechecks the article and picture and makes sure that no mistakes have happened before or during typesetting. When all is set and ready (text, headlines, pictures, layout, and design) the complete page is photographed and a film negative (a large black and white film) generated from which the printing plates (plastic-coated zinc or aluminium printing plates) for the presses are made. The drafts are circulated by the sports editor and the editor. Once the pages have been approved, and checked by the proofreaders, they are taken to the printing department. Now, the final reports are ready to be photographically transferred to plastic-coated zinc or aluminium printing plates. The plates pickup the images in ink and transfer them to the paper. The papers are now ready for distribution. The papers should reach the customers well in time. The success here is determined by the speed at which the newspapers distribute their copies to their readers. To help them achieve this, they first distribute the first edition to the far-flung areas and then to the nearer areas. These latter editions may look a bit different from the earlier editions as a result of fresh news breaking out which may in turn claim space on the front page. All the newspapers in India are sold out the next morning. As Indians are enjoying and discussing their country’s first Olympic gold medal, quoting from various newspaper articles and pictures, the sports reporters and photographers are awaiting their next assignment from their editors. For these reporters and photographers their day is yet to begin.

A lot of people like Astronomy.  Many of these are men of science studied by train who study it by trade.  Others are regular people who enjoy it as a hobby.  Some of these hobbyists have even made important discoveries at times.  In the old days it was the job of telescopes.  Today however, computers make it possible to practice astronomy without them thanks to astronomy software.  This is a discussion of just some of the available software.

SETI@Home home is very popular.  The idea behind this software was to create supercomputer made up of many small computers connected via the Internet.  SETI, the search for extraterrestrial intelligence, scanned through space with a radio telescope seeking intelligent patterns.  Supercomputers on site were used to analyze the data.  But now all that computing power is distributed online.  People at home won’t be having discussions with aliens when they’re found.  But people can take pride in being involved in the search for intelligence outside our home planet.

A 3-D screen saver is another type of astronomy software.  These programs kick in when a PC is idle, and show various space objects rendered in spectacular 3D computer graphics.  This can include simple views as well as navigable planets, solar systems or other objects that the user can explore from any angle and distance.  Search “3D Space Tour” on Google or Yahoo to find some of these fun programs.

Most people don’t know about F.I.T.S.  It’s Flexible Image Transport System, which is a NASA and IAU endorsed format to store and deliver not only images but spacial data and multi-dimensional arrays such as 2-D and 3-D images.  It’s used in a lot of software.  These include freeware and software for sale.  A web search will find many more.  Duke’s physics website lists many more.

Software such as Aberrator allows an amateur astronomer to view images of stars through various telescopes with aberrations in the lens.  The software displays images that help the hobbyist adjust the telescope.

Astronomy software is as varied as the universe.  Web search for it, you’ll be pleasantly surprised.
