Pluto's icy surface conceals vast ocean?

PLUTO may have a vast ocean beneath its frozen crust, according to researchers studying a heart-shaped feature on the dwarf planet’s surface.

Captured in high resolution by the New Horizon’s spacecraft in 2015, the bright, heart-shaped expanse is known as Tombaugh Regio, the left lobe of which is formed by the 1,000-kilometer wide Sputnik Planitia. 

This plain is thought to have arisen after a meteorite slammed into Pluto’s surface billions of years ago, producing a crater that later filled with nitrogen ice.

But scientists have been puzzled as to why Sputnik Planitia lies near Pluto’s equator and faces almost…

Life on Mars could be 'far beneath the surface'

MARS is almost devoid of surface water with areas that are drier than the driest deserts on Earth – so any life would have to be “far below the surface” to survive, scientists have said.

An international team of researchers looked for evidence of rust on metals in meteorites that have hit the Red Planet as a way to gauge the level of moisture.

A previous study found evidence that very salty water might be able to condense on the Martian surface.

But the new research, led by Sterling University academics, suggests only a tiny amount of liquid is being…

 Mystery of Bermuda Triangle finally cracked?

FOR OVER a century, theories have abounded over the mystery behind the Bermuda Triangle where more than 75 planes and hundreds of ships are said to have disappeared. Scientists may now have an answer.

It’s thought that hexagonal clouds over the 1.3 million sq km (500,000 square miles) of ocean between Bermuda, Florida and Puerto Rico, could be creating huge 106 kph (170mph) wind “air bombs” and these deadly blasts of air can tear down trees, topple over ships and bring planes crashing down.

Researchers analyzed imagery from a NASA satellite and found the hexagon-shaped clouds 240 km off…

Scientists baffled by recurring cases of two-headed sharks

Two-headed sharks may sound like a figment of the big screen, but they exist—and more are turning up worldwide, scientists say.

A few years ago off Florida, fishermen hauled in a bull shark whose uterus contained a two-headed fetus. In 2008, another fisherman discovered a two-headed blue shark embryo in the Indian Ocean.

And a 2011 study described conjoined twins discovered in blue sharks caught in the Gulf of California and northwestern Mexico. Blue sharks have produced the most recorded two-headed embryos because they carry so many babies—up to 50 at at time, says study leader Felipe Galván-Magaña, of the…

The Universe Has 10 Times More Galaxies


MORE than a trillion galaxies are lurking in the depths of space, a new census of galaxies in the observable universe has found — 10 times more galaxies than were previously thought to exist.

An international team of astronomers used deep-space images and other data from the Hubble Space Telescope to create a 3D map of the known universe, which contains about 100 to 200 billion galaxies. 

In particular, they relied on Hubble's Deep Field images, which revealed the most distant galaxies ever seen with a telescope. 

Then, the researchers incorporated new mathematical models to calculate where…
