Weird Glowing Jellyfish Spotted Near Mariana Trench

A unique glowing jellyfish has been found in the depths of Mariana Trench, which looks like an alien spacecraft coming straight out of a science fiction movie.

Researchers from National Oceanic and Atmospheric Administration (NOAA) were looking for so-called Enigma Seamount during the fourth dive of their expedition when they came across the weird creature floating 3,700 meters beneath the surface.

The thing which makes the jellyfish looks like an alien spaceship is its unusual bell. Inside the bell, red canals can be seen connecting to the bright yellow points, which are giving the creature a beautiful glowing look.

Three Earth-like Planets Discovered Orbiting Dwarf Star

Scientists have discovered three planets orbiting a cool dwarf star just 40 light years away from the Earth. The size and temperature of these planets is similar to our planet and provides the best chances to search for life beyond the Earth.

The planets were spotted by using a 60-centimeter telescope TRAPPIST, whose job is to observe nearby cool and small stars. The newfound star, called 2MASS J23062928-0502285, is one-eighth size of our Sun and is extremely cold while the three objects around it are indeed planets. The new discovery reinforces the idea of existence of life beyond our solar system.

New Analysis Reveal Genetic Secrets of Ice Age Europeans

Researchers have recently sequenced the DNA of 51 prehistoric individuals that lived in Europe from 45,000 to 7,000 years ago. They not only found the details about the biology of early inhabitants like their skin and eye color but it was also revealed that these populations had gone through two complex migrations at the end of the last Ice Age.

Researchers suggest that glaciers were covering areas from Scandinavia to northern Europe to northern France at the height of the last Ice Age. But around 19,000 years ago when the ice sheet started melting, Europe was populated by prehistoric humans from southwest Europe. Then, around 14,000 years ago, population from now Turkey and Greece ventured into the Europe and displaced the first group of humans.

Astronomers Measure the Mass of a Black Hole with Extreme Precision

Astronomers have been able to gauge the mass of a distant black hole with unprecedented precision. The massive black holes lies in the center of an enormous elliptical galaxy called NGC 1332 located 73 million light years away from the Earth.

To measure the exact mass of black hole, researchers turned to ALMA and looked at its observational data regarding the orbiting speed of the dense clouds of interstellar gas and dust that surrounds the black hole. Researchers found that the black hole is 660 million times greater than the mass of the Sun.

Streaky Slopes on Mars may be Created by Boiling Water

Mars has hundreds of unique dark colored streaky slopes on its surface. These streaks appear in warm season and fade as the planet cools.

Now, researchers have figured out what cause those streaky slopes on Martian surface. In a groundbreaking experiment, researchers used a special chamber and replicated the conditions of Mars warm day. Then, they placed a block of ice on a plastic slope covered with fine sand at a temperature of 30 degrees Fahrenheit and allowed it to melt under the mimicked Mars pressure and summer temperature. The resulting shape was remarkably similar to the streaks seen on Martian surface. Researchers found that the boiling caused grains of sand to blast into the air and made them appear like bubbles popping across the hills.
