Three-year coral reef airborne lab mission to solve problems related to coral’s health

A project head by NASA is underway that aims to find out mysteries regarding what factors drive coral reef health. The data from the study could help experts have better information to tackle the problem efficiently.

Alaska can be seen like never before in new most accurate digital elevation maps

Alaska can be seen like never before in new most accurate digital elevation maps

Alaska is among the most poorly mapped places on the planet. In reality, until now the topographic maps of the Red Planet and the moon were typically more detailed in comparison to those of the Arctic state. The White House, National Science Foundation and National Geospatial Intelligence Agency (NGA) have this week shared the most precise digital elevation maps of Alaska ever made.

Over 400 years old Petroglyphs may help shed light on lineal descendants of island of Oahu

Over 400 years old Petroglyphs may help shed light on lineal descendants of island of Oahu

Hawaii's Department of Land and Natural Resources has announced about finding petroglyphs considered to be dating back to over 400 years. The petroglyphs, images carved into rock, were found while shifting sands on Hawaii's Waianae coast on the island of Oahu.

The department officials are quite happy with the find as the petroglyphs are considered to be a rarity. The engravings were found by a Texas couple in July while they were walking along the beach. Not one, but the couple has found up to 10 carvings along 60 feet of beach.

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.
