They are competing standards to be the successor to DVD. One is endorsed by Sony, the other by Toshiba. They both offer dramatic improvements over DVD in quality and the amount of data which can be stored, but they require very different hardware and manufacturing processes. This basics are described in these articles:

The major differences are MPEG2 and MPEG4 HD can utilize MPEG4 and MPEG2, where as BluRay only uses MPEG2, storage size HD - About 15GB single BD - About 25GB single. The drawback with BD (Blue Discs/BluRay) is that thanks to Sony's dragging their feet on development, and that HD DVD is actually got the upper hand since MPEG4 has also been pretty much adopted as the next step in formatting video for playback the BD's none support of it is a hindrance, then add in the fact that the HD Players are half the price (cheap about $200-300 high end $700-800) and more readily available in comparison to BD/BR players (Cheapest is the PS3 at $599.99 the most available one is just under $1k). BDs are still very sensitive to scratching, though Sony/Panasonic claim their techniques for protecting them have advanced. Who knows which will get more movies, Sony is being jerks about releasing their films to HD, but some are sneaking in, and many companies are distributing both just for a wider market.
Remember BD is from the people who brought you BetaMax, which was a better quality product than VHS, just to damb costly.

HD-DVD is a standard proposed by a consortium of companies that includes hollywood biggies and software giant microsoft. HD-DVDs can store 15GB data per layer. The discs look similar to standard DVD discs and Moser Baer in India has already started mass production.
Blue-Ray is a standard proposed chiefly by Sony and actively marketed. Blue-Ray discs can store 25GB per layer. Blue-ray is currently the most visible high capacity disc technology.
When launched, HD-DVD may become more ubuquitous under the industry push.

Here's an interesting technical editorial article on the subject:
