“We have a strong indication that the uppermost 2,480 meters contain a climate record that goes back to 1.2 million years in a high-resolution record where up to 13,000 years are compressed into one meter of ice,” Julien Westhoff from Copenhagen University said in a press statement.

This week, uncover some of the oldest ice on Earth, follow a dinosaur highway, learn how Pluto sealed the capture of its moon Charon with a “kiss,” and more.

China has announced plans to build a giant solar power space station, which will be lifted into orbit piece by piece using the nation's brand-new heavy lift rockets.

Three-million-year-old tools found in Kenya reveal early humans' ability to cut food, butcher meat, and adapt to new diets.

Tony Stark's Iron Man was the beginning of something bigger in Marvel town. Nick Fury said in The Avengers that, "The idea was to bring together a group of remarkable people to see if they could become something more.
