From, throw out, sharper

Webcast: Live from convention

I didn't get "from". Does it mean "The (GOP) convention makes our living better"?

Justice Department seeks to throw out major terror conviction

Does "throw out" mean "deny"?

Astronomers have discovered four new planets in a week's time, an exciting end-of-summer flurry that signals a sharper era in the hunt for new worlds.

What does "sharper' mean here?

Sounds like a newscast, and the reporter is on the scene at the convention - i.e., reporting live from the covention

The most likely scenario is as follows:
There was a trial. Sombody was convicted (found to be guilty) by a jury. JD wants a judge to overturn the verdict of the jury. JD seeks to have the conviction thrown out of court by the judge.

Sharper doesn't work well here unless there is a context of competition among astronomers looking for new planets, resulting in a sharper era of competition[/b][/i]

Thanks bigjohn.

Got them now, except "sharp era" remaining a bit confusion.
