NASA spacecraft's close call with Martian moon Phobos

NASA spacecraft's close call with Martian moon Phobos

NASA's Mars Atmosphere and Volatile Evolution Mission (MAVEN), which is in its second year of studying the Red Planet's atmosphere, was recently forced to perform unscheduled maneuver to avert a space-wreck.

In its first collision avoidance maneuver, MAVEN spacecraft carried out a rocket motor burn that boosted its velocity by 0.4 meters per second (less than 1 mile per hour) to steer clear of Mars' moon Phobos, NASA reported.

The correction was small, but it was enough for the spacecraft to avoid the crater-filled moon by about 2.5 minutes.

Gang warfare not unique to humans - banded mongooses do it too

Gang warfare not unique to humans - banded mongooses do it too

Researchers from the University of Exeter have shed light on the causes of the fights - and found they are most common when females are receptive to breeding and when there is competition over food and territory.

The study has been published in the journal Animal Behaviour. The scientists, who studied a population of banded mongooses in Uganda, observed ferocious fighting between groups that often led to serious injury and even death.

Egg-free surrogate chickens can save rare poultry breeds

Egg-free surrogate chickens can save rare poultry breeds

To boost breeding of endangered poultry breeds, Briton researchers have come up with gene-editing techniques for the rare breeds to use them as surrogates that cannot produce their own chicks.

The advance -- using gene-editing techniques -- could help to boost breeding of endangered birds, as well as improving production of commercial hens, researchers say.

Meet 'Bernardbowen'- the new minor planet

Meet 'Bernardbowen'- the new minor planet

In a major development, a team of scientists have officially named a minor planet as 'Bernardbowen' that sits in the asteroid belt between Mars and Jupiter.

The minor planet was discovered on October 28, 1991, and until now has been known as (6196) 1991 UO4, but the name has been given by an Australian citizen science project 'theSkyNet', who won a competition to name the celestial body.

The planet was named by the International Centre for Radio Astronomy Research (ICRAR) in honour of their founding chairman Dr. Bernard Bowen.

NASA needs your help in finding new ninth planet

NASA needs your help in finding new ninth planet

New York [USA], Feb. 17 : NASA has called on the world to help it in the search for the new ninth planet, as anyone from a kindergartener to a 95-year-old, can participate in their new project to find the not-yet-discovered celestial body.

To let anyone participate in this search project of ninth planet, the Zooniverse space projects site has launched a NASA-funded venture, Backyard Worlds: Planet 9, reports CNN.

"There are really low barriers to entry," Dr. Laura Trouille of Zooniverse.

Two largest satellite galaxies Magellanic Clouds bridged by stars

Two largest satellite galaxies Magellanic Clouds bridged by stars

According to an international team of astronomers led by researchers from University Of Cambridge, the Magellanic Clouds, the two largest satellite galaxies of the Milky Way, appear to be connected by a bridge stretching across 43,000 light years.

The discovery is based on the Galactic Stellar census being conducted by the European Space Observatory, Gaia and reported in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).

Universe could be a vast, complex hologram: Study

A study has provided, what researchers believe is the first observational evidence, that our universe could be a vast and complex hologram.

The researchers, from the University of Southampton (UK), University of Waterloo, Canada, Perimeter Institute (Canada), INFN, Lecce (Italy) and the University of Salento (Italy), have published findings in the journal Physical Review Letters.

Scientists discover giant otter fossils in China

Scientists discover giant otter fossils in China

A team of researchers have discovered prehistoric wolf-sized otter fossils with a large head and a powerful jaw, weighing around 100 pounds, in China's Yunnan province.

The study, published in journal of Systematic Paleontology, claims it to be the largest otter, Siamogale melilutra, almost twice as large as the largest living otters.

It had a large and powerful jaw with enlarged bunodont (rounded cusped) cheek teeth.
