Our planet has a space junk problem

Our planet has a space junk problem

Earth has a space junk problem. Russian scientists launched the small satellite Sputnik in 1957. The satellite’s beeping signal is likely to mark the beginning of the Space Race. Such a thing would provoke Americans to launch Explorer I soon after.

The metal sphere was only the first of a number of satellites, rocket parts and spacecraft debris that constitute the over 500,000 bits of miscellany bigger than a marble that is presently orbiting our planet.

Newly-discovered species of shark appropriately given common name ‘Ninja Lanternshark’

Newly-discovered species of shark appropriately given common name ‘Ninja Lanternshark’

A newly-found species of shark has jet black skin and a dim glow, and it is a master of stealth. It has been given a common appropriate name ‘Ninja Lanternshark’. It lives in waters from 2,742 feet to 4,734 feet, or 836 to 1443 meters, deep, in the Pacific Ocean, off the coast of Central America.

A team of scientists have detailed the new found shark in a study carried by the Journal of the Ocean Science Foundation. One of the scientists in the team said that the animal owes its different name to Vicky Vásquez’s young cousins.

Coastguard warns public to stay away from decomposed carcass of whale washed ashore on Whales beach on Christmas Day

Coastguard warns public to stay away from decomposed carcass of whale washed ashore on Whales beach on Christmas Day

On Christmas day, a whale was washed ashore on a Wales beach. Its body could pose a health risk, and the Coastguard has cautioned people to stay away from it. Thought to be a Minke whale, the dead animal was washed ashore at Dyfi Ynyslas National Nature Reserve.

The animal was discovered on the sands at Ynyslas, nearby Aberdyfi and 8 miles north of Aberystwyth, in Ceredigion.

NASA temporarily suspends Insight Mission to Mars due to seismometer leakage issue

NASA temporarily suspends Insight Mission to Mars due to seismometer leakage issue

NASA has announced that its Insight mission to Mars has been delayed due to leakage issue in the seismometer developed by French space agency CNES. The technical team at CNES had noticed a leakage in the seismometer few weeks back and it was first confirmed by NASA on December 3. NASA was expecting CNES to deliver seismometer by January 2016.

Florida wildlife agency may tighten rules for owning venomous reptiles

Florida wildlife agency may tighten rules for owning venomous reptiles

Following a couple of escapes of venomous reptiles in the recent past, Florida wildlife officials are considering stricter rules for owning venomous reptiles like cobras and anaconda.

Authorities confirmed that the Florida Fish & Wildlife Conservation Commission is considering new rules and indicated that ownership of such reptiles could be banned altogether.

New Horizons’ LEISA instrument records movie for edge of our solar system

New Horizons’ LEISA instrument records movie for edge of our solar system

Using its infrared imaging spectrometer called LEISA, American space agency NASA’s New Horizons spacecraft recorded a movie for the first time from the edge of our solar system.

LEISA recorded the movie with a 256 x 256 pixel camera at a speed of two frames per second. The clever instrument takes 2-D images in a manner as a normal camera takes, but it took the images through a linearly-varying filter. One side of the camera can see only light of one specific wavelength of infrared light, and each row of pixels can see a dissimilar wavelength.

UCLA Researchers Create Strong Lightweight Metal with High Stiffness to Weight Ratio

UCLA Researchers Create Strong Lightweight Metal with High Stiffness to Weight Ratio

Nanoparticles are very small particles with extrinsic properties; one amongst them is the tendency to enhance the strength of metals without damaging their plasticity, especially light metals like magnesium. Nanoparticles tend to clump together due to the tendency of small particles to attract each other, rather than disperse evenly. Till now, none of the scientists have been able to disperse ceramic nanoparticles in molten metals.

Mother Nature Celebrated Christmas This Year with Full Moon after 40 Years

Mother Nature Celebrated Christmas This Year with Full Moon after 40 Years

On the eve of Christmas season, when the whole world was busy in welcoming the God father, our mother nature too was busy in making the day even more special. Santa’s sleigh was not the only object seen in the sky on Christmas Day instead the Friday’s lunar show was the first full moon on Christmas in past 38 years. The full moon illuminated Christmas this week gained attraction from people all over the world. The full moon was covered by clouds with in a big chunk of the United States, but in places with clear skies it was quite the holiday treat.

Researchers create new metal with superior stiffness-to-weight ratio

Researchers create new metal with superior stiffness-to-weight ratio

A team of researchers at the UCLA Henry Samueli School of Engineering & Applied Sciences has created a highly strong but lightweight metal that could lead to development of advanced aircraft, spacecraft and cars.

The new metal “nanocomposite,” which contains nearly 86 per cent magnesium and 14 per cent silicon carbide by weight, is capable of absorbing and withstanding very high levels of heat without having its integrity changed. In others words, the new silicon carbide-infused magnesium demonstrates record levels of specific strength & specific modulus.

Oso, Washington might have witnessed major landslides in the past as well: UW Research

Oso, Washington might have witnessed major landslides in the past as well

The landslide that caused a major mudslide in Oso, Washington in March 2014 has been termed as the deadliest landslide in the history of United States. However, a new research has indicated that the landslides in the region could be a recurring phenomenon. The study published in the journal Geology has suggested that the region might have witnessed a massive landslide nearly 500 years ago.
