The crater isn’t confirmed as a meteor impact yet – that takes further research – but it looks very likely that it is one. This discovery shows how @NASA ’s ongoing study of our home planet helps us understand how it interacts with the space around us. https://t.co/lGL9yMPHx1

The verdict? It’s possible that two craters 🕳🕳 formed at different times ⏰ in Earth’s history. All it took were data from NASA satellites 🛰 and airborne missions ✈️ like Operation #IceBridge to reveal where the craters were hiding.
impacts this large are rare occurring once every 2 million years how likely is it for two large craters to be
Impacts this large are rare, occurring once every 2 million years. How likely is it for two large craters to be so close together? To answer that question, @NASAEarth scientists looked to a body with almost no erosion, where impact craters are much better preserved: the Moon 🌕.
the two greenland craters are only about 114 miles apart but at first glance they dont seem to have formed at
The two Greenland craters are only about 114 miles 📏 apart, but at first glance they don’t seem to have formed at the same time. The newly discovered crater is more eroded and the ice ❄️ above it is thicker and older than over the Hiawatha crater.

Finding new impact craters on Earth can be hard. Water 💧 and weather 🌨 erode the landscape relatively quickly, geologically speaking. Scientists were surprised to find evidence of craters under ice sheets, which generally grind the land down faster than we can locate craters.
this isnt the first time scientists have used data to identify an impact crater under earths ice sheets this p
This isn’t the first time scientists have used @NASA data 📈 to identify an impact crater 🕳 under Earth’s ice sheets. This past November, a team announced discovery of a different crater under Greenland’s Hiawatha Glacier. https://t.co/S9aReB81bP

A possible crater 🕳 caused by a meteor impact ☄️ lies buried beneath more than a mile of ice ❄️ in Greenland. It’s more than 22 miles 📏 wide, which would make it the 22nd largest impact crater ever found on Earth. https://t.co/5F2uZbEPl1
from yesterday s flight a tabular iceberg can be seen on the right floating among sea ice just off of the lars
From yesterday's #IceBridge flight: A tabular iceberg can be seen on the right, floating among sea ice just off of the Larsen C ice shelf. The iceberg's sharp angles and flat surface indicate that it probably recently calved from the ice shelf.
wow its been amazing to see what a splash our photo of a tabular antarctic iceberg by s jeremy harbeck has mad
Wow, it’s been amazing to see what a splash our photo of a tabular Antarctic iceberg, by #IceBridge ’s Jeremy Harbeck, has made. Fly toward the berg with 's DC-8 forward camera. More: https://t.co/kADuUL455F
