Scientists are increasingly linking Antarctic ice sheet to the level of carbon dioxide in the atmosphere. Supporting the idea, a new research published in the Journal Science claimed that during the time when ice sheet first started appearing, a fall in CO2 in atmosphere may have let ice sheet to form.

According to the research, the period known as the Eocene-Oligocene boundary, which prevailed some 34 million years ago, is believed to have been an era that led to periods of glaciations. The research has found that falling level of carbon dioxide back then has initiated ice sheet growth.

In an initiative to make future missions to the red planet successful, NASA recently launched an experimental rocket engine, which would be used to power future spacecraft to Mars and to other regions that are far off in our galaxy. The success of the launch was announced on Friday by the American space agency.

As an integral part of the Space Launch System (SLS) program, NASA had developed RS-25 rocket engine that was tested on Thursday, the high-powered device blast continuously for 500 seconds. Another rocket would be tested by NASA in near future.

The team members of Jeff Bezos’ space venture Blue Origin were aware that there would be queries when the company called up media to its Kent, Washington office this week. It was the first time ever that the press got the chance to enter Blue Origin, which has worked under the wraps till date. The rocket company floated by Jeff Bezos has been working on interesting space travel projects.

During a tour and roundtable, reporters threw lot of questions at Bezos. The conversation went on for four hours.

Some of the key questions asked during the meeting were:

Durable plastic sold under commercial name PET is considered as a massive environmental hazard because it is resistant to breakdown. However, researchers have discovered a potential new match for this tough plastic. During a research project a research team from Japan has come across a microbe that is amazingly good at eating PET plastic sheets.

According to the World Economic Forum, production of an estimated 342 million tons of plastic is recorded each year across the world, and just nearly 14% is collected for recycling.

Almost all plastic degrades at an extremely slow pace, but PET, which stands for polyethylene terephthalate, is among the most durable. In year 2013 alone, nearly 61 million tons of the colorless plastic was produced across the world.

The total solar eclipse witnessed this week was not seen in the United States. NASA has released an interesting video of the solar eclipse which was visible in most parts of Indonesia and many countries in Asia. The Internet is overflowing with pictures and videos of total solar eclipse, the only one of 2016, but it’s difficult to beat the composite footage released by NASA.

The brief clip released by NASA showcases the eclipse not from Earth’s surface, as done by most of the sky gazers, but from deep space, focused at our wonderful blue marble.

NASA officials made an announcement on March 11 that astronaut Scott Kelly, who has lately completed an extraordinary yearlong mission aboard the International Space Station (ISS), and is holder of the American record of spending most number of days out of Earth, will retire on April 1.

Post retirement, Scott Kelly will keep on taking part in the research linked to his one-year space mission, which was planned to assist in clearing the way for crewed missions to the Red Planet by highlighting the ways long-duration spaceflight affects the body of a human being both psychologically and physiologically.
