Season 3.0 of "Battlestar Galactica" ends tonight, and when season 3.5 begins next month it will be on a new night.

The show moves to Sundays on Jan. 21.

As has become common operating procedure for "Galactica," it's taking a midseason break after tonight's episode (7 and 9 p.m., Sci Fi Channel). So ... we're going to get a big cliffhanger!

There is, of course, continuing conflict between the humans and the Cylons. On the algae planet, the humans have found the Temple of Five. And, according to legend, that's the home of the Eye of Jupiter. And, according to legend, the Eye of Jupiter contains the key to finding the lost planet Earth.

But the Cylons have found out that the humans have found the Temple of Five. And they want the key to Earth themselves. Which sets up a cliffhanging conflict between humans and Cylons.

And that's not all. Baltar (James Callis) and D'Anna (Lucy Lawless) are stirring up trouble inside the Cylon fleet. And — gasp! — Sharon (Grace Park ) has discovered that the half-Cylon, half-human baby she gave birth to didn't die, as she was told.

It's great stuff.

"Battlestar Galactica" remains one of the best shows on TV. And — stop me if you've heard this before — it's not just for sci-fi geeks. This is great drama set against a sci-fi background, but it's by no means a special-effects show.

It's not unusual for TV critics to get review copies of episodes that aren't quite completed — that don't have the special effects yet. And that affects, oh, maybe a couple of minutes of a "Galactica" episode.

The unfortunate thing is that the ratings haven't been really good this season. Which is prompting the move to Sundays.

Hopefully, the move will work. There are few shows on any network that deserve an audience more than "Battlestar Galactica."

IN THE WAKE OF my most recent column gushing over the wonderful-ness of "Heroes," a bunch of readers want to know how they can catch up with the series.

OK, if you've never watched an episode, the Sci Fi Channel is repeating the pilot today at 5 p.m. (Sci Fi airs repeats every Friday at 5 p.m. On Dec. 22, it will air Episode 9, "Homecoming.")

And next month NBC will repeat five of the 11 episodes that have aired to date.

On Monday, Jan. 1, on Ch. 5, you can see Episode 5 ("Hiros") at 7 p.m.; Episode 6 ("Better Halves") at 8 p.m.; and Episode 7 ("Nothing to Hide") at 9 p.m.

On Monday, Jan. 8, on Ch. 5, you can see Episode 9 ("Homecoming") at 8 p.m.; and Episode 11 ("Fallout") at 9 p.m.

Or you can go on the Internet and see any or all of the 11 episodes at nbc.com.

If you haven't gotten hooked on "Heroes" yet, it's not too late!
