Pinky the rare albino dolphin has been spotted in Lake Calcasieu in Louisiana, USA Photo: CATERS NEWS

Charter boat captain Erik Rue, 42, photographed the animal, which is actually an albino, when he began studying it after the mammal first surfaced in Lake Calcasieu, an inland saltwater estuary, north of the Gulf of Mexico in southwestern USA.

Capt Rue originally saw the dolphin, which also has reddish eyes, swimming with a pod of four other dolphins, with one appearing to be its mother which never left its side.

He said: “I just happened to see a little pod of dolphins, and I noticed one that was a little lighter.

“It was absolutely stunningly pink.

“I had never seen anything like it. It’s the same color throughout the whole body and it looks like it just came out of a paint booth. Read more »

LONG BEACH, Calif. — Space is typically thought of as a very quiet place. But one team of astronomers has found a strange cosmic noise that booms six times louder than expected.

The roar is from the distant cosmos. Nobody knows what causes it.

Of course, sound waves can’t travel in a vacuum (which is what most of space is), or at least they  can’t very efficiently. But radio waves can.

Radio waves are not sound waves, but they are still electromagnetic waves, situated on the low-frequency end of the light spectrum.

Many objects in the universe, including stars and quasars, emit radio waves. Even our home galaxy, the Milky Way, emits a static hiss (first detected in 1931 by physicist Karl Jansky). Other galaxies also send out a background radio hiss.

But the newly detected signal, described here today at the 213th meeting of the American Astronomical Society, is far louder than astronomers expected.

There is “something new and interesting going on in the universe,” said Alan Kogut of NASA’s Goddard Space Flight Center in Greenbelt, Md.

Research shows at least some areas of planet was less hostile to life.

Evidence of a key mineral on Mars has been found at several locations on the planet’s surface, suggesting that any microbial life that might have been there back when the planet was wetter could have lived comfortably.

The findings offer up intriguing new sites for future missions to probe, researchers said.

Observations NASA’s Mars Reconnaissance Orbiter (MRO), which just completed its primary mission and started a second two-year shift, found evidence of carbonates, which don’t survive in conditions hostile to life, indicating that not all of the planet’s ancient watery environments were as harsh as previously thought.

WASHINGTON – Astronomers have stumbled upon a tremendous hole in the universe. That has got them scratching their heads about what is just not there.

The cosmic blank spot has no stray stars, no galaxies, no sucking black holes, not even mysterious dark matter. It is 1 billion light years across of nothing.

That is an expanse of nearly six billion trillion miles of emptiness, a University of Minnesota team announced today.

Astronomers have known for many years that there are patches in the universe where nobody is home.

In fact, one such place is practically a neighbour, a mere two million light years away.

But what the Minnesota team discovered, using two different types of astronomical observations, is a void that’s far bigger than scientists ever imagined.

“This is 1,000 times the volume of what we sort of expected to see in terms of a typical void,” said Minnesota astronomy professor Lawrence Rudnick, author of the paper that will be published in Astrophysical Journal.

“It’s not clear that we have the right word yet … This is too much of a surprise.”
