Mercury’s major volcanic activity ended 3.5 billion years ago

It has been about 3.5 billion years ago Mecury had its major volcanic activity
A research paper published in the Geophysical Research Letters journal has unveiled that the last volcanic activity on Mercury ended around 3.5 million years back. The findings could help researchers to explore more about the geological evolution of the planet.

Thousands gather to see smiley face in erupting Kilauea volcano

Thousands gather to see smiley face in erupting Kilauea volcano

Thousands are coming to see the cheerful Kilauea volcano, which has been erupting since 1983. ‘Cheerful’ because a smiley face has been formed in an erupting Hawaiian volcano's crater. The smiley was captured in a video by a helicopter tour company.

Mick Kalber from Paradise Helicopters has captured the moment. Also, the lava flow from the Kilauea volcano is reaching at the Pacific shore of the Big Island, also known as Hawaii. It seems that the lava will make the Big Island even bigger.

Lava breakout from Kilauea volcano flows into Pacific Ocean

Lava breakout from Kilauea volcano flows into Pacific Ocean

Lava flow is originating from Kilauea volcano’s Pu ‘u ‘Ō ‘ō vent. The lava breakout in Hawaii has flowing to the Pacific Ocean last after slowing moving towards the coast for weeks. As per the USGS Hawaiian Volcano Observatory, the flow entered into the water at 1:12 am HST on Tuesday.

From the videos and photos shared, it has been found that the bright red lava produced massive amount of steam as it entered in the water. The breakout started to take place in late May and since then it has moving slow towards the coastline.

Scientists find evidence of facial tumor after jaw analysis of dwarf dinosaur

Scientists find evidence of facial tumor after jaw analysis of dwarf dinosaur

For the first time, researchers have discovered a type of non-cancerous facial tumor, found in humans, mammals and some reptiles, in fossil animals. An international team of researchers has found timorous facial swelling in the fossil of the jaw of the dwarf dinosaur Telmatosaurus transsylvanicus in Transylvania.

Monumental platform uncovered in ancient city of Petra in Jordan

Monumental platform uncovered in ancient city of Petra in Jordan

Using Google Earth, satellite imagery, ground work and photography, researchers have uncovered a large new monumental platform in the Petra World Heritage site in Jordan. The large rectangular platform measures around184 feet by 160 feet.

The researchers said that within this platform, there is another, smaller platform. The site is present just half a mile from the center of the 2,500-year-old city. The study researchers Sarah Parcak and Christopher Tuttle said that the platforms also have a small building.

Ancient underwater structures off Greece built by bacteria

Ancient underwater structures off Greece built by bacteria

Mysterious structures spotted around 20 feet under the sea near the Greek isle of Zakynthos were first thought to be a lost city made by humans. In reality, it is the work done by bacteria, finds a new research paper published in the Marine and Petroleum Geology.

When archaeologists saw and assessed it properly, they suspected that it is not a city. There were no coins, pottery fragments or any other sign of life. They then evaluated the mineral content of the structures and found them to be a perfectly natural origin.

Geologists discover lava rocks on Baffin Island bearing traces of over 4.5 billion years old molten material

Geologists discover lava rocks on Baffin Island bearing traces of over 4.5 billion years old molten material

Geologists have found lava rocks on Baffin Island of Canada bearing traces of over 4.5 billion years old molten material. Led by Dr. Hanika Rizo from the Université de Montréal, the research team was astonished to discover the material that dates back to the days of formation of Earth into an iron-rich core, a silicate covering and an outer rocky crust.

Scientists estimate that the Earth’s crust has been created 4.5 billion years back, from the upward rise of melted mantle after the downward sinking of its denser elements back towards the core of Earth.

Geophysicists give possibility of Pavlof Volcanic eruption for second time this year

Scientists at the Alaska Volcano Observatory claimed that Alaskan volcano is all set to blow again after March 27 eruption when it released a volcanic ash cloud 37,000 feet into the air. The ash was so thick that it covered tiny coastal village of Nelson Lagoon.

Research: 2.7 billion years ago, Earth's air weighed less than half what it does today

Research: 2.7 billion years ago, Earth's air weighed less than half what it does today

As per new research appeared on Monday in the journal Nature Geoscience, around 2.7 billion years back, the air of Earth weighed less than half what it does presently. If confirmed, this finding would prompt a shift from the main perspective that ancient atmosphere was double as thick as today's, which therefore can possibly alter the answer to a very old scientific mystery called the ‘faint young sun paradox’.

That time, our sun was nearly 20% dimmer as compared to it is now, which means the rays of the sun wouldn’t have warmed the surface of Earth as readily.

Half of UNESCO World Heritage sites in danger Due to human activity

Half of UNESCO World Heritage sites in danger Due to human activity

According to a report commissioned by the World Wildlife Fund (WWF), half of the UNESCO World Heritage sites around the world are in danger due to human activities, predominately industrial development over exploitation of resources that include mining and logging. The WWF asks companies to leave such sites untouched for their safety and sustenance.
