APOD: 2008 September 19 - Companion of a Young  Sun like Star

This is big news.  An actual photograph of a planet in another solar system.  Within the last few years, they’ve found scads of planets around other solar systems, but I’ve never heard of there being a direct photograph.

From APOD:


  this picture likely represents the first direct image of a planet belonging to a star similar to the Sun.


Does that mean there have been other direct images of planets around non sun-like stars?

In any case, this is incredibly cool.

APOD: 2008 August 9 - Aurora Persei

This looks like a Web 2.0 design.

APOD: 2008 July 28 - SDSSJ1430: A Galaxy Einstein Ring

This is some crazy, relativistic stuff right here—gravity bending light into a circle.  The computer generated images of the individual parts are especially cool.

APOD: 2008 July 23 - High Cliffs Surrounding Echus Chasma on Mars

This is the kind of APOD I like: nobody really knows what’s going on here.  This one is also great because I was sure it was an illustration.  Nope—it’s a photo from the Mars Express orbiter.  It really looks like an illustration in a science book from the 50s or 60s.

APOD: 2008 July 15 - Gas and Dust of the Lagoon Nebula

Pictures like this where they remove the stars are really striking.  If most of what was removed was foreground stars, I suppose this gives a more realistic view of what it would be like to be closer.

APOD: 2008 July 14 - Changes in Angular Mars

I had never thought of this—since Mars is further from the sun than we are, we never see Mars (or any other planet further out than we are) in a crescent phase.

APOD: 2008 June 25 - What is Hannys Voorwerp

I love this kind of thing. We have no idea what this is.  Here’s a green blob that some random person (not an astronomer) found by browsing images online.  Astronomers don’t know what it is!

I might have to come back to this and write more later.

 APOD: 2008 June 19 - The Star Streams of NGC 5907


  Grand tidal streams of stars seem to surround galaxy NGC 5907.


I wonder what life is like (if it’s possible) around those far-flung wisps of stars.  The victims of violence on a scale so grand, it’s undetectable on human timescales unless you’re millions of light-years away.

 APOD: 2004 March 9 - The Hubble Ultra Deep Field

It amazes me that this is one continuous view of deep space.  Everything is a galaxy.  Lots and lots of tiny (as seen by us) galaxies.
