And then, there is Earth. When we think about space, we rarely consider our own planet, a “blue marble” against the dark void. Apollo 11 astronaut Michael Collins, who we lost this week, reminded us what a marvel it truly is.
“Strangely enough, it looks fragile somehow,” he said. “You want to be good to it. All the beauty, it was wonderful.”
But Collins never felt that way. He referred to Columbia as a “happy home” that reminded him of a cathedral and the entire mission as a “long and very fragile daisy chain.” Every link in that daisy chain worked. The three men made history that still inspires the spirit of space exploration more than 50 years later.
Fossils and fireballs
When meteorites land on Earth, scientists often wonder exactly where they came from in our solar system.
Scientists uncovered a total of 23 fragments after the fireball lit up the skies over the Central Kalahari Game Reserve in Botswana on June 2, 2018.
Scientists first thought it belonged to an existing species when they found it in the Mantiqueira mountain range in 2016.
A long time ago…
Insights into the struggle between an ice age predator and its prey have been revealed by the latest research of fossils found at Friesenhahn Cave outside of San Antonio.
Saber-toothed cats stalked 2-year-old mammoths — and likely brought the kills back to their cave to eat, the study has suggested.
But these fearsome feline hunters didn’t mess around with the larger mammoths. Even saber-toothed cats had a limit.
Across the universe
What looks like a cotton candy explosion in space is actually a portrait of the elements — including ones we use on Earth like iron and titanium — that remain after a star exploded. The first of its kind, the photo depicts the moment following the creation of stable titanium.
Glaciers are melting even faster than expected.
Satellite data collected by NASA helped researchers determine that glacier melt has doubled over the past two decades.
