Water Clouds Tentatively Detected Just 7 Light Years From Earth

by Ken Crosswell

Astronomers have found signs of water ice clouds on an object just 7.3 light-years from Earth—less than twice the distance of Alpha Centauri, the nearest star system to the sun. If confirmed, the discovery is the first sighting of water clouds beyond our solar system. The clouds shroud a Jupiter-sized object known as a brown dwarf and should yield insight into the nature of cool giant planets orbiting other suns.

Kevin Luhman, an astronomer at Pennsylvania State University, University Park, recently discovered the nearby object by using images from NASA’s WISE infrared space telescope, which scanned the sky from 2010 to 2011. A brown dwarf is a failed star and has so little mass that it can’t sustain nuclear reactions, so after its birth it fades and cools. This brown dwarf, named WISE J0855-0714, is the coldest known. Its temperature is slightly below the freezing point of water, so it’s colder than Earth’s mean temperature but warmer than Jupiter’s…

HOW THE MOKIN CHILDREN ARE ABLE TO SEE WITH AMAZING CLARITY UNDERWATER

The Mokin are a group in Thailand that are nomadic and have a sea-based culture. 

In the sea there is less light, so usually one’s iris will dilate. But the Mokin have an adaption where instead of dilating, they constrict as much as possible. 

This allows them to see with much better clarity. Recent studies suggest that any child can quickly learn this trick. It exemplifies how well our brain adapts to our environment.

Like all living things, humans are bio­luminescent (meaning we glow) – We glow brightest during the afternoon. weirdinteresting & funny facts

what

i’ve been staring at this for like 5 minutes. so.. what. i don’t think people glow. but this is telling me that we actually emit visible light.. especially in the afternoon?? am i reading this right or what

"all living things" plants. when do the plants glow

science side of tumblr pls

I’m not from the science side of tumblr, but here’s the answer anyways:

 Basically, all living things are bioluminescent because every living thing has chemical reactions occurring in their cells. The energy created from these chemical reactions physically manifests as light, thus… all living things naturally glow.

 However, this glow cannot be seen by the human eye. In fact, the only way they’ve ever captured this light is through special cameras. Using these ultra special cameras, they’ve imaged subjects’ bodies over 24 hour periods. It has been found out that humans emit the most of this glow during the afternoon (about 4 PM), it is the weakest in the morning (about 10 AM), and the brightest light is emitted from the cheeks, neck, and forehead.

The light is about a thousand times weaker than what humans can perceive.

 Basically, it’s a side effect of metabolic reactions. It’s been suspected that humans are bioluminescent for years, but they weren’t able to confirm it until recently thanks to technology and a man named Masaki Kobayashi from the Tohoku Institute of Technology.

A Sunda flying lemur hangs from a tree branch by holding on with its arms and legs as he enjoys a rest. It uses its body like a hammock and relaxes by resting its head on the edge of its back. The bat-like creature - pictured snoozing in Sekura in Indonesia - slept for 15 minutes before it woke up to manoeuvre along the branch.

GOOD NEWS:

New population of Critically Endangered parakeets found in Brazil

Researchers supported by the Conservation Leadership Programme have uncovered a small population of grey-breasted parakeets nesting on a mountain in north-east Brazil.

by Sarah Rakowski

A team of scientists searching for remnant populations of the Critically Endangered grey-breasted parakeet has found a small group nesting in a small crevice on the top of a rugged mountain ridge in north-east Brazil.

Only around 300 of these birds are thought to remain in the wild, all of which are found in the Brazilian state of Ceará.

As part of a national action plan for the species, researchers from local organisation Aquasis have searched more than 20 sites for signs of the parakeet, focusing their efforts on areas identified as having high habitat potential or historical sightings.

This new discovery brings the total number of known groups up to three. By comparison, historical data show that at least 15 separate populations once existed…

For more than three billion years, the Earth harbored only single-celled organisms. At some point, multi-cellular life appeared, in the form of jellyfish, worms, and sponges. But these early animals, being soft-bodied, left few fossil traces. About 560 million years ago, animals with shells formed, and their skeletal remains left markers in the sediments. Within tens of millions of years, most groups of organisms that we recognize today had appeared, in what is known as the Cambrian explosion.
