Think of what you notice on Earth each day: the shapes of clouds, how hot the sun feels on your skin, the colors of the sky when the sun sets.
Our corner of the cosmos remains filled with discoveries just waiting to be made.
Across the universe
Mars has a thin, dry atmosphere. That means clouds tend to appear in the skies over its equator when the planet is farthest from the sun and at its coldest.
The iridescent clouds form at a higher altitude, so they are essentially made of dry ice (frozen carbon dioxide). Scientists are still studying them to figure out why this happens.
A long time ago…
Archaeologists have made a grisly discovery at three Roman cemeteries in eastern England.
The rural settlements these people belonged to across Cambridgeshire helped provide the Roman army with food between 250 A.D. and 325 A.D.
It’s unclear why they were beheaded, but researchers believe tensions with the Roman army came into play.
They call it puppy love for a reason. It turns out that puppies have excellent social skills because they are born ready to love and interact with people.
Researchers evaluated these skills in 375 8-week-old retrievers for a new study (dream job alert).
This involved making eye contact with the pups and having them follow hand and eye gestures toward hidden treats.
The planet may have been the first habitable world in our solar system, including an ocean and climate similar to Earth — but something happened to turn it into a crucible with temperatures hot enough to melt lead.
Only two prior NASA missions have visited Venus — Pioneer in 1978 and Magellan in the early ’90s.
The Southern Ocean around Antarctica is a wild place, with such terrifying waves and wicked winds that few humans have dared cross it. Home to unique marine life, the body of water also plays another vital role: absorbing 12% of the carbon dioxide we create each year.
For the last 10 years, French explorer and environmentalist Dr. Jean-Louis Étienne has worked on designing a vessel that could withstand these brutal conditions while gathering scientific data.
The result: a floating laboratory called the Polar Pod. An engineless vessel designed to flip on its side, the pod will be driven by the Antarctic Circumpolar Current.
The crew will remain in the top portion during the journey. Scientists will be able to listen to sea creatures beneath the water and understand how much carbon dioxide is in the ocean.
