Ninety-six years ago today, the Titanic spent its last day above water. “Titanic and Today, An Evening Exploring the Arctic Then and Now” explores the sinking of the unsinkable ship and what, if anything, could have been done to prevent it. We might think today’s technology would mean the ship would have no trouble navigating the icy sea, but oceanographer Chris Linder spent the last year studying the Arctic’s ever-changing waterways and has a lot to say about that.

Following Linder will be historian Carolyn Sumners, who’ll discuss the latest Titanic discoveries and introduce the Burke Baker Planetarium’s newest film, Night of the Titanic, which will be timed so that the sinking of the ship occurs at the same time it did almost a century ago (which, we have to admit, kind of creeps us out). 7 p.m. Houston Museum of Natural Science, One Hermann Circle. Night of the Titanic runs through May 25. For tickets and information, call 713-639-4629 or visit www.hmns.org. $12 to $17.
