A strong signal detected by Russian radio telescope last year stirred excitement among scientific community. Scientists thought that the signal came from HD164595, a star system located 95 light years away from Earth and is probably an indication of extraterrestrial life out there.
Now, SETI Institute has conducted a followed up investigation and swung their Allen Telescope Array in the direction of the patch of the sky where the signal was supposedly came from but failed to catch anything.
After futher processing, researchers believe that the unusual signal more likely originated from Earth, not from space, putting an end to the speculations about the existence of alien life.
The discovery of the fossil of close human relative dubbed Lucy is one of the most famous discoveries in the field of paleontology. Lucy was a three feet tall female who lived 3.2 million years and whose fossil bones were recovered from Ethiopia in 1974. For more than 40 years, ever since the discovery of fossil, researchers have been trying to unlock the mystery of Lucy’s death.
Now, researchers have finally figured out how our most famous human ancestor died. The fossil and scanning of the fractures on her skeleton paint a more clear picture of what happened in here final moments and researchers conclude that Lucy died from a long fall out of a tree.
Scientists have discovered the oldest physical evidence of life on earth in Greenland. They are strange microbes that lived on seafloor 3.7 billion years ago and are 220 million years older than any previously confirmed fossil evidence.
The microbes came into existence just half a billion years after the Earth formed and indicate that life may have burst onto the scene more quickly than previously thought. The fossils are basically stromatolites which are layered structures produced by microbial communities. The stromatolites are about .4 to 1.6 inches high and emerged from the newly melted part of Greenland.
Dwarf planet Ceres continues to baffle scientists with its diversity. For the first time, NASA‘s Dawn spacecraft has found direct evidence of icy volcanism on dwarf planet and it is in the form of giant icy volcano called Ahuna Mons.
Ahuna Mons is a huge mountain which stands 13, 000 feet tall and 11 miles wide at its base – almost half the height of Everest. Finding an ice volcano in outer space is strange but not beyond the imagination. The freezing cold celestial bodies could have harbor these kinds of icy features on their surface. However, scientists are not sure how such a giant, isolated mountain was formed on the dwarf planet Ceres.
NASA’s Juno spacecraft has sent back the first-ever images of Jupiter’s north pole as it got close to the planet with its instruments switched on. The images show unusual storm systems and cloud tops over the giant planet which are hardly recognizable even for the astronomers themselves and they believe these images are unlike anything previously seen on any of our solar system’s gas-giant planets.

The Images reveal that the north pole of Jupiter is more bluer in color and a lot more active than other parts of the planet.
