The unusual image blew up online and now NASA is back with more photos of weirdly angular icebergs from the same Operation IceBridge trip.
We usually think of icebergs as craggy chunks like the one from Titanic, but IceBridge senior support scientist Jeremy Harbeck caused a stir after he captured photos of the flat, sharp-cornered specimens.
"I thought it was pretty interesting; I often see icebergs with relatively straight edges, but I've not really seen one before with two corners at such right angles like this one had," Harbeck said in a NASA post.

These nature-made frozen slabs have an official name: "tabular icebergs." Because of its smooth surface and clean edges, the rectangular berg likely only recently broke off the Larsen C ice shelf, which famously released a Delaware-sized chunk of ice last year, now dubbed A68.
"The iceberg's sharp angles and flat surface indicate that it probably recently calved from the ice shelf," NASA tweeted.
In the new photo (at the top of this article), Harbeck captured a slightly less rectangular iceberg around the same area. Look closely and you can see a corner of the now-classic rectangular iceberg as well as A68 in the distance.
"I was actually more interested in capturing the A68 iceberg that we were about to fly over, but I thought this rectangular iceberg was visually interesting and fairly photogenic, so on a lark, I just took a couple photos," Harbeck added in the NASA post.
These calving events are like a long fingernail that eventually snaps off at the end, University of Maryland Earth scientist Kelly Brunt explained to LiveScience.
Such a break can create nearly perfect geometric edges, similar to when a glass plate shatters and creates straight edges, sea ice specialist Alek Petty told NPR.

Tropical forests globally are being lost at a rate of 61,000 square miles a year. And despite conservation efforts, the global rate of loss is accelerating. In 2016 it reached a 15-year high, with 114,000 square miles cleared.
At the same time, many countries are pledging to restore large swaths of forests. The Bonn Challenge, a global initiative launched in 2011, calls for national commitments to restore 580,000 square miles of the world's deforested and degraded land by 2020. In 2014 the New York Declaration on Forests increased this goal to 1.35 million square miles, an area about twice the size of Alaska, by 2030.

Do you think almond milk comes from a cow named Almond? Or that almonds lactate? The dairy industry thinks you do, and that's what it's telling the Food and Drug Administration (FDA).
For years, the dairy industry has been flexing its lobbying muscle, pressuring states and the federal government to restrict plant-based companies from using terms like "milk" on their labels, citing consumer confusion.

A driver planning to make the trek from Denver to Salt Lake City can look forward to an eight-hour trip across some of the most beautiful parts of the country, long stretches with nary a town in sight. The fastest route would take her along I-80 through southern Wyoming. For 300 miles between Laramie and Evanston, she would see, according to a rough estimate, no fewer than 40 gas stations where she could fuel up her car. But if she were driving an electric vehicle, she would see just four charging stations where she could recharge her battery.
Fire Continues at Texas Petrochemical Plant as Company's History of Violations Gets Renewed Scrutiny
By Andrea Germanos
A petrochemical plant near Houston continued to burn for a second day on Monday, raising questions about the quality and safety of the air.
The Deer Park facility is owned by Intercontinental Terminals Company (ITC), which said the fire broke out at roughly 10:30 a.m. Sunday. Seven tanks are involved, the company said, and they contain naptha, xylene, "gas blend stocks" and "base oil."
"It's going to have to burn out at the tank," Ray Russell, communications officer for Channel Industries Mutual Aid, which is aiding the response effort, said at a news conference. It could take "probably two days" for that to happen, he added.
The hillsides dyed orange with poppies may look like something out of a dream, but for the Southern California town of Lake Elsinore, that dream quickly turned into a nightmare.
The town of 66,000 people was inundated with around 50,000 tourists coming to snap pictures of the golden poppies growing in Walker Canyon as part of a superbloom of wildfires caused by an unusually wet winter, BBC News reported. The visitors trampled flowers and caused hours of traffic, The Guardian reported.
A controversial pesticide test that would have resulted in the deaths of 36 beagles has been stopped, the Humane Society of the United States (HSUS) and the company behind the test announced Monday. The announcement comes less than a week after HSUS made the test public when it released the results of an investigation into animal testing at Charles River Laboratories in Michigan.
"We have immediately ended the study that was the subject of attention last week and will make every effort to rehome the animals that were part of the study," Corteva Agriscience, the agriculture division of DowDupont, said in a statement announcing its decision.
