Hubble Telescope Captures Penguin Guarding its Egg



The Hubble Space Telescope has captured a pair of giant galaxies that bear a striking resemblance to a penguin guarding its egg.

This cosmic  find—known as Arp 142—is in reality the blue spiral galaxy, NGC 2936, twisted by the gravitational pull of the smaller elliptical galaxy NGC 2937 below it.

Hubble captures exquisite details within the tortured “penguin” galaxy. 

  • Its bright core, represents “eye” of this celestial penguin , is filled with millions of stars huddled together. 
  • The red streak slashing across the penguin’s face just above its eye is the warped remains of what was once a spiral arm.
  • The bird’s celestial body is composed of the pinwheeling spiral arms of former galaxies which now only show up as bright, feathery blue and red streaks stretching out for thousands of light years.

The galactic pair is 400 million light-years away from Earth in the southern constellation Hydra. They are in the midst of a slow motion collision—violently exchanging material and  disrupting their original structures.

The tiny, elongated red and blue smudges in the background—which look like pesky flies—are in reality much more distant galaxies.

How marine mammals hold their breath?

How marine mammals hold their breath

The sperm whale can dive for up to an hour and to depths of a kilometre

Scientists say they have solved the mystery of one of the most extreme adaptations in the animal kingdom: how marine mammals store enough oxygen to hold their breath for up to an hour.

The team studied myoglobin, an oxygen-storing protein in mammals' muscles and found that, in whales and seals, it has special "non-stick" properties.

This allowed the animals to pack huge amounts of oxygen into their muscles without "clogging them up".

The findings are published in ScienceMag.org.

Dr Michael Berenbrink from the Institute of Integrative Biology at the University of Liverpool took part in the study.
He said that scientists had long wondered how marine mammals managed to pack so much of this vital protein into their bodies.At high enough concentrations, [proteins] tend to stick together, so we tried to understand how seals and whales evolved higher and higher concentrations of this protein in their muscles without a loss of function
The team extracted pure myoglobin from the muscles of mammals - from the land-based cow, to the semi-aquatic otter, all the way up elite divers like the sperm whale.

Led by researcher Scott Mirceta, this painstaking examination traced the changes in myoglobin in deep-diving mammals through 200 million years of evolutionary history.

And it revealed that the best mammalian breath-holding divers had evolved a non-stick variety of myoglobin.

Dr Berenbrink explained
The secret was a subtle but crucial piece of chemical trickery; marine mammal myoglobin is positively charged.This has important physical consequences. Like the similar poles of a magnet; the proteins repel one another.In this way we think the animals are able to pack really high concentrations of these proteins into their muscles and avoid them sticking together and clogging up the muscles.
I was excited by the discovery because it helped make sense of the incredible changes that took place in mammals' bodies as they evolved from land-based animals to the aquatic, air-breathing creatures that inhabit the oceans today.It showed the physiological change that accompanied the land to water transition of mammals.It also allows us to estimate the dive times of the ancient ancestors of whales.
We can look the fossils and predict the dive times they had.
Understanding exactly how mammals' bodies store oxygen so efficiently could also aid medical research.
Copying this bit of natural chemistry could aid the development of oxygen-carrying liquids that would deliver emergency supplies of oxygen to a person's tissues when a blood transfusion is not possible.

But its biggest impact will be in the realm of evolutionary biology.

Harbour seals routinely hold their breath for 30 minutes and even sleep underwater
Nicholas Pyenson, curator of fossil marine mammals at the Smithsonian Institution in Washington DC, said 
The study was an exciting advancement for understanding the evolution of deep-diving.The idea that we can estimate maximal dive times for early diverging relatives of today's marine mammals will have a profound impact on how we think about their ancient ecology and biology.

Professor Michael Fedak from the University of St Andrews' Sea Mammal Research Unit pointed out that myoglobin was only "part of the story" of how marine mammals were able to dive.

"But it's an important part," he said.

The scientist, who was not involved in this study, explained that a great deal of research at the moment was looking into how marine mammals manage to survive repeatedly cutting off and re-establishing the blood supply to their body tissues, something he likened to repeatedly suffering a crush injury.

"But being able to pick up a few [fossilised] bones of an extinct marine mammal and estimate its dive time from that - that's miraculous."

5 Sky Events This Week: You don't want to miss!

This week skywatchers get a chance to watch the  most elusive of naked-eye  sky show of the year.


Moon with Venus
About 30 minutes after sunset on Monday, June 10, skywatchers around the world had looked towards the very low northwest for the razor-thin crescent moon to the left of Venus.

Surprise meteor shower? 

The gamma Delphinids are coming to Earth tonight, NASA says, as it predicts that the early hours of Tuesday, June 11, will bring the best visibility of the meteors since they were first observed in 1930. People in North and South America may be able to spot them in areas with dark skies, the agency says.
Because no viewing of the gamma Delphinids has been strongly confirmed since a group of Maryland sky watchers reported seeing them in 1930, the meteor shower has retained an air of mystery.
While there is no guarantee, the best bet to observe any activity will be to find a dark location away from city lights and face the southern sky where the meteors will appear to radiate out from their namesake constellation, Delphinius (the dolphin) before local dawn. 


Mercury at its best

On Wednesday, June 12, Mercury will be at its farthest possible separation from the sun in our evening sky for the entire year, positioned at its very best for mid-northern latitude observers. Mercury will be easy to find even for a novice because Venus acts as a convenient guide, appearing less than 5 degrees below (equal to the width of your three middle fingers at arm’s length).
Even a small telescope adjusted with high power will reveal that Mercury disk is about 40% illuminated and looks like a miniature version of the crescent moon.


Moon joins lion’s Heart  

Thursday, June 13, for the crescent moon will be hanging below the brightest star of constellation Leo, the lion.
Regulus marks the heart of the lion and lies 78 light years away. A hot blue-white star, it is about 3.5 times larger than our Sun and, at 300 million years old, is an adolescent when it comes to star lifetimes.
By the next evening, June 14,  the moon will slid to the lower left of Regulus. Meanwhile southern hemisphere observers will see the crescent moon to the immediate left of the brilliant blue-white star.


Mars meets Aldebaran 

Saturday, June 15, try to spot down the Red Planet  in the very low eastern sky near Aldebaran, the red eye of Taurus, the bull constellation.
Start spotting  about an hour before your local sunrise and look for Aldebaran to the lower right of Mars (upper right in southern hemisphere). The planet-star pair will appear higher in the sky–and therefore brighter and easier to spot–the more southerly your observing location. Binoculars will help in tracking down both objects.
While both morning stars shine with similar brightness and orange tinges, they lie at very different distances. Mars is currently stationed 369 million kilometers (229 million miles) from Earth, while the dying red giant star is a respectable 65 light years off.

The Top 10 New Species List of 2013

The top 10 new species list was announced May 23 by the International Institute for Species Exploration at Arizona State University.



A global committee of taxonomists—scientists responsible for species exploration and classification—announced its list of top 10 species from 2012 today, May 23.

The 2013 list includes an amazing glow-in-the-dark cockroach, a harp-shaped carnivorous sponge, the smallest vertebrate on Earth, a snail-eating false coral snake, flowering bushes, a green lacewing, a hangingfly fossil, a monkey with a blue-colored behind and human-like eyes, a tiny violet and a black staining fungus. 

In this only glow-in-the-dark cockroach, a harp-shaped carnivorous sponge and the smallest vertebrate on Earth are just three of the newly discovered species.

Members of the international committee made their top 10 selection from more than 140 nominated species. Species  have been described in compliance with the appropriate code of nomenclature, whether botanical, zoological or microbiological, and have been officially named during 2012.


The top 10 come from Peru; NE Pacific Ocean, USA: California; Democratic Republic of the Congo; Panama; France; New Guinea; Madagascar; Ecuador; Malaysia; and China.

Top 10 New Species, 2013



Viola liliputana 
Country: Peru

Tiny violet: Lilliputian violet is among the smallest violets in the world and one of the most diminutive terrestrial dicots.
 Known only from a single locality in an Intermontane Plateau of the high Andes of Peru, Viola lilliputana lives in the dry puna grassland eco-region.
Specimens were first collected in the 1960s, but the species was not described as a new until 2012.
The entire above ground portion of the plant is barely 1 centimeter tall. Named for the race of little people on the island of Lilliput in Jonathan Swift's Gulliver's Travels.

Chondrocladia lyra 
Country: NE Pacific Ocean; USA: California

Carnivorous sponge: A spectacular, large, harp- or lyre-shaped carnivorous sponge discovered in deep water (averaging 3,399 meters) from the northeast Pacific Ocean off the coast of California. 

The harp-shaped structures or vanes number from two to six and each has more than 20 parallel vertical branches, often capped by an expanded, balloon-like, terminal ball. 
This unusual form maximizes the surface area of the sponge for contact and capture of planktonic prey.

Cercopithecus lomamiensis 
Country: Democratic Republic of the Congo

Old World monkey: Discovered in the Lomami Basin of the Democratic Republic of the Congo, the lesula is an Old World monkey well known to locals but newly known to science. 

This is only the second species of monkey discovered in Africa in the past 28 years.
Scientists first saw the monkey as a captive juvenile in 2007. 

Researchers describe the shy lesula as having human-like eyes. More easily heard than seen, the monkeys perform a booming dawn chorus.

 Adult males have a large, bare patch of skin on the buttocks, testicles and perineum that is colored a brilliant blue.

 Although the forests where the monkeys live are remote, the species is hunted for bush meat and its status is vulnerable.
Sibon noalamina 
Country: Panama

Snail-eating snake: Discovered in the highland rainforests of western Panama.

The snake is nocturnal and hunts soft-bodied prey including earthworms and amphibian eggs, in addition to snails and slugs. 

This harmless snake defends itself by mimicking the alternating dark and light rings of venomous coral snakes. 

The species is found in the SerranĂ­a de TabasarĂ¡ mountain range where ore mining is degrading and diminishing its habitat. The species name is derived from the Spanish phrase "No a la mina" or "No to the mine."

Ochroconis anomala 
Country: France

Fungus: In 2001, black stains began to appear on the walls of Lascaux Cave in France. By 2007, the stains were so prevalent they became a major concern for the conservation of precious rock art at the site that dates back to the Upper Paleolithic. 

An outbreak of a white fungus, Fusarium solani, had been successfully treated when just a few months later, black staining fungi appeared. 

The genus primarily includes fungi that occur in the soil and are associated with the decomposition of plant matter. 

As far as scientists know, this fungus, one of two new species of the genus from Lascaux, is harmless. However, at least one species of the group, O. gallopava, causes disease in humans who have compromised immune systems.

Paedophryne amanuensis 
Country: New Guinea

Tiny frog:  The new frog, as small as 7 millimeters, was discovered near Amau village in Papua, New Guinea. 

It captures the title of 'smallest living vertebrate' from a tiny Southeast Asian cyprinid fish that claimed the record in 2006. 

The adult frog size, determined by averaging the lengths of both males and females, is only 7.7 millimeters. 

With few exceptions, this and other ultra-small frogs are associated with moist leaf litter in tropical wet forests—suggesting a unique ecological guild that could not exist under drier circumstances.

Eugenia petrikensis 
Country: Madagascar

Endangered shrub: Eugenia is a large, worldwide genus of woody evergreen trees and shrubs of the myrtle family that is particularly diverse in South America, New Caledonia and Madagascar. 

The new species E. petrikensis is a shrub growing to two meters with emerald green, slightly glossy foliage and beautiful, dense clusters of small magenta flowers. 

It is one of seven new species described from the littoral forest of eastern Madagascar and is considered to be an endangered species. 

It is the latest evidence of the unique and numerous species found in this specialized, humid forest that grows on sandy substrate within kilometers of the shoreline. 

Once forming a continuous band 1,600 kilometers long, the littoral forest has been reduced to isolated, vestigial fragments under pressure from human populations.

Lucihormetica luckae 
Country: Ecuador

Glow-in-the-dark cockroach: 
Since the first discovery of a luminescent cockroach in 1999, more than a dozen species have "come to light."
All are rare, and interestingly, so far found only in remote areas far from light pollution. 

The latest addition to this growing list  of luminescent cockroach is L. luckae that may be endangered or possibly already extinct. 

This cockroach is known from a single specimen collected 70 years ago from an area heavily impacted by the eruption of the Tungurahua volcano. 

The species may be most remarkable because the size and placement of its lamps suggest that it is using light to mimic toxic luminescent click beetles.

Semachrysa jade 
Country: Malaysia

Social media lacewing: Hock Ping Guek photographed a beautiful green lacewing with dark markings at the base of its wings in a park near Kuala Lumpur and shared his photo on Flickr.

 Shaun Winterton, an entomologist with the California Department of Food and Agriculture, serendipitously saw the image and recognized the insect as unusual. 

When Guek was able to collect a specimen, it was sent to Stephen Brooks at London's Natural History Museum who confirmed its new species status. 

The three joined forces and prepared a description using Google Docs. In this triumph for citizen science, talents from around the globe collaborated by using new media in making the discovery. 

The lacewing is not named for its color—rather for Winterton's daughter, Jade.

Juracimbrophlebia ginkgo folium 
Country: China

Hangingfly fossil: Living species of hangingflies can be found hanging beneath foliage where they capture other insects as food. 

They are a lineage of scorpionflies characterized by their skinny bodies, two pairs of narrow wings, and long threadlike legs. 

A new fossil species, Juracimbrophlebia ginkgo folium  has been found along with preserved leaves of a gingko-like tree, Yimaia capituliformis, in Middle Jurassic deposits in the Jiulongshan Formation in China's Inner Mongolia. 

The two look so similar that they are easily confused in the field and represent a rare example of an insect mimicking a gymnosperm 165 million years ago, before an explosive radiation of flowering plants.

Monster radiation burst from Sun


The Sun has unleashed its most powerful eruption of 2013 so far.


The solar flare - a sudden release of radiation - peaked at 1705 BST on Monday, and was associated with a huge eruption of matter.



When these eruptions reach Earth, they can interfere with electronic systems in satellites and those on the ground.

Nasa said this solar explosion - known as a coronal mass ejection (CME) - was not directed at Earth, but it could pass several US spacecraft.

The event on Monday was classified as an "X-class" flare - the most intense type - with a designation of X2.8 (higher numbers denote a stronger flare). It surpassed an X1.7-class flare that occurred 14 hours earlier.


They are the first X-class events to occur this year.
When intense enough, a flare can disturb the Earth's atmosphere in the layer where GPS and communications signals travel.

This disrupts the radio signals for as long as the flare is ongoing - the radio blackout associated with this flare has since subsided.

The short film, 'A Boy and His Atom', was made using thousands of these precisely placed tiny molecules.

  ‘A Boy and His Atom’ This is the name of the world shortest movie made by the scientists from IBM, a Guinness World Record.The film was made using thousands of precisely placed atoms. It consist of almost 250 frames of stop-motion action.

        And the story of the movie goes like this......

    -> There was boy named Atom.
  ->Atom  befriends a single atom and  they goes on a journey.
 -> There were lot of difficulties in their journey.
 -> They had to dance, they were playing catch, and the deadliest part, they were bouncing on a trampoline.
