Awesome Astronomy!

This is a great way to stay on top of all of the latest astronomy news. Portal to the Universe collects together all of the key astronomy press releases as they appear from all of the major institutions across the world. These are the authoritative sources so it's a great way to get the real story. The newspaper-style layout on iPads is an excellent addition!

Just what I was looking for, but the text is too small! Please fix!

Portal to the Universe

This has a good interface--with a good set of science new stories. However, the set of headlines, photos, etc. take up too much of the screen. As a result, one has to scroll through page after page (each with only about 4 or 5 photos/headlines on it) to find what one wants. There should be a text only mode for headlines, perhaps with mini photos, that could show a dozen or so stories.

Yet, the real problem is that the text in the stories
, especially on many of the pages one goes to, is far too small to read comfortably! There is no way of resizing the text with reflow! The opening headline, short paragraph view text is OK, though we could still use a font size control for it. But the real problem is that many, if not most, of the stories, blogs, etc., that one goes to have far too small text, and the pinch-zooming biz puts most of the text off the screen, so that you are forever scrolling back and forth!

I realize that's partly due to the web site one goes to, but there needs to be a way of making the text bigger and having it reflow within the visible screen! Various browsers now can do it. But there's no excuse not to have font resize-reflow within the app itself!

As it stands, alas, it's unreadable and unusable! 2 stars and deleted. Hope the developers fix this!
