Hubble Spots Most Distant Galaxy Ever Seen

NASA’s Hubble Space Telescope gazed at the farthest galaxy ever seen in the universe. The galaxy, called GN-z1, is 13.4 billion light years in the past and was formed just 400 million years after the Big Bang. With the discovery, Hubble has shattered all the previous distance record set by other powerful telescopes for years.

The newfound galaxy is 25 times smaller than our galaxy Milky Way. However, it is forming stars at a startling rate, about 20 times greater than our galaxy produces today.

NASA’s Astronaut Scott Kelly Returns to Earth after a Year Long Mission

Astronaut Scott Kelly has returned to Earth after spending 340 days aboard International Space Station. 

The 52 year old astronaut’s one-year mission started in March 2015. He alongside other astronauts had to stay in orbiting laboratory for a long time and had to cope up with hostile conditions in outer space. During his stay on board ISS, veteran astronaut conducted several experiments in microgravity conditions which could pave the way for future NASA’s missions to deep space.

Astronomers Detect Repeating Fast Radio Burst for the First Time

Astronomers have long thought that fast radio bursts appear occasionally and in the form of a single flash but a team of international researchers have detected a new kind of radio bursts which explode over and over again. The discovery was made possible by radio telescope Arecibo. 

Researchers suspect that these flashes are originated from an extremely powerful object that has a capacity of producing multiple intense burst of radio waves per minute.

Next, researchers are aiming to expand their research and will look for the source of these mysterious repeating fast radio bursts by using a telescope with more resolving power than Arecibo 

Fossilized Fungus May be the Oldest Land Fossil Ever

Researchers from University of Cambridge claim that the 440 million year old fungus fossil is the oldest land fossil yet found.

The threads of prehistoric fungus were discovered in Sweden and Scotland almost 30 years ago but previously they were not identified. The threads are shorter than a human hair is wide and looks similar to their modern relatives. 

Scientists are hesitant to claim that this fossil fungus was the oldest organism to live on Earth but it is the oldest fossil of a land creature ever known. 

Oldest and Most Detailed Nervous System Discovered in China

Researchers have discovered probably the oldest and most detailed nerves system in southern China. The nervous system belongs to a crustacean like animal that lived more than 500 million years ago. The fossil is so well preserved that its individual nerve fibers are still visible and has not decomposed over time which usually happens to soft tissues.

Each nerve strand is 10 times thinner than a human hair but its neurological details are amazing. The fossil can help scientists to find out the evolution of nerves system in modern-day animals.
