Most of us learned about the world's oceans in elementary school. There's the Pacific, the Atlantic, the Indian and the Arctic.

Now, there's a sea change ahead.

Thanks to National Geographic, you'll soon see a fifth ocean on your maps. It's now officially recognizing the Southern Ocean, the waters swirling around Antarctica, marking the first time the organization has made such a change since it started drawing up maps over a century ago.

The National Memorial Day Concert on Sunday night was less of a concert than it was a muted, broadcast tribute to the sacrifices and heroism of American veterans, fallen service members and their families.

The PBS event wove together vignettes spotlighting veterans, musical performances from noted artists and archival footage across decades of war. Celebrated actors lent their talents to tell first-person accounts of veteran trailblazers. The pre-taped concert, usually held at the West Lawn of the U.S. Capitol building, was semi-virtual this year because of COVID-19 protocols.

The first cruise set to sail from American ports in more than 15 months is headed to the Caribbean this summer.

Celebrity Cruises got approval from the Centers for Disease Control and Prevention to bring passengers aboard for the seven-night cruise on June 26, the company announced this week.

"CDC and the cruise industry agree that the industry has what it needs to move forward and no additional roadblocks exist for resuming sailing by mid-summer," CDC spokesperson Caitlin Shockey confirmed in an email.

Internet Explorer is nearing the end of a long and slow death, Microsoft announced this week.

At 25 years old, the much-reviled web browser that once dominated the Internet couldn't shake its reputation as the slow, buggy net-surfing option.

Microsoft has been stepping away from the product since at least 2015, when it introduced its successor, Microsoft Edge (previously known as Project Spartan). By mid-June of next year, the Internet Explorer desktop app will finally be put to rest.

After a long, dark year, social muscles have atrophied. In-person gatherings now call for weighty questions about COVID-19 safety. And many people, who during the pandemic found relief in empty calendars, don't want to go back to the world as they knew it.

Swaths of East Coasters who looked up at the night sky on Sunday were treated to a light show, courtesy of NASA's Black Brant XII rocket. And they've got the pictures to prove it.

The rocket launched at 8:44 p.m. ET from the Wallops Flight Facility in Virginia. But it was the "vapor tracers" that it released into the atmosphere that most spectators glimpsed shooting across the sky.

Tech billionaire Elon Musk hosted Saturday Night Live this weekend, in a debut performance that drummed up a lot of reaction before his big night even began.

As the night unfolded, Musk, CEO of electric carmaker Tesla and chief engineer of SpaceX, played a range of characters, including: a doctor at a Gen Z hospital, a priest and self-confessed murderer in a Mare of Easttown parody, an anti-social party guest in a post-pandemic world — and, naturally — himself.

Pfizer and its vaccine partner BioNTech have started an application to request the Food and Drug Administration's approval for its COVID-19 vaccine.

President Biden threw his support behind a World Trade Organization proposal on Wednesday to waive intellectual property protections for COVID-19 vaccines, clearing a hurdle for vaccine-strapped countries to manufacture their own vaccines even though the patents are privately held.

And so it goes: Burning Man 2021 is canceled. It's the second year in a row that the popular arts festival won't be held in Nevada's Black Rock Desert due to the pandemic.
