New Graphene-based Light Detector sees what Human Eyes can’t

New Graphene-based Light Detector sees what Human Eyes can’t

A new graphene-based light detector could see things that human eyes can't. The detector is able to measure the light's wavelength.

Terahertz radiation, also known as submillimeter radiation, consists of electromagnetic waves. The radiation is located between infrared and microwave frequencies on electromagnetic spectrum, range of frequencies of electromagnetic radiation.

The detector would help scientists in making more sensor devices with much greater sensitivity than current technology.

Astronauts from NASA’s NEEMO 18 Program Spending Time at Aquarius

Aquarius is the only underwater laboratory present 19 meters below the surface of earth. It is located around five kilometres away from Key Largo Island.

Researchers who are part of NASA's Extreme Environment Missions Operations (NEEMO) 18 program are present at the lab. Four astronauts are in the lab and are training themselves for a mission that would take them on the surface of an asteroid.

Tetrad of Lunar Eclipse to come on April 14

Tetrad of Lunar Eclipse to come on April 14

Beautiful scene of biggest lunar eclipse will be clearly visible on the night of April 14 and in the morning of April 15 from North and South America. During the lunar event, moon will be turned completely dark-copper red, which scientists have dubbed as an event of 'Blood Moon'.

'Blood Moon', an event popular in certain religious faiths, has served as a sign of ominous events like the apocalypse in historic life. 'Blood Moon' is described as the onset of the world's end and the second coming of Jesus Christ in Christianity.

Higgs Left behind because of an Early Night

Higgs Left behind because of an Early Night

Nobel laureate Peter Higgs said he failed to make a key connection between his work and that of others during a science meeting in 1960, otherwise he could have been one of the architects of physics biggest theory.

MIT Engineers Find a Way to Find Out Mass of Particles at Attogram Scale

MIT Engineers Find a Way to Find Out Mass of Particles at Attogram Scale

A new method to gauge the weight of particles has been found by MIT engineers. The resolution of the method is better than an attogram, which is one millionth of a trillionth of a gram. Mass of both synthetic nanoparticles and biological components of cells can be measured with this method.

Finding the mass of these particles could assist researchers in understanding their compositions and functionalities.

Metamaterials Can be Used to Perform Analog Computing

Metamaterials Can be Used to Perform Analog Computing

A research has been carried out by a group of researchers from the University of Pennsylvania. Generally, meta-materials, which often makes an object visible, have been found to be having another use and that to a significant one.

The study researchers have found that these meta-materials can be used in order to do advanced mathematical calculations done by computer. It shall however, be noted that for now they have not come up with a device that works with the help of the same.

Time Travel into the Past is Nearly Impossible

Time Travel into the Past is Nearly Impossible

A number of physicists have tried to see whether travel into the past is possible or not. As predicted, they have concluded that for now, time travel into the past is almost impossible.

In 2005, an MIT graduate student hosted a convention with regard to time travel, but not many attended the same. Stephen Hawking even sent invitations for a summer soiree, but then also there were not many participants.

Triple Star System Could be Used to Resolve Problems of Fundamental Physics

Triple Star System Could be Used to Resolve Problems of Fundamental Physics

According to a new report, astronomers have discovered a unique stellar system comprising two white dwarf stars and a super dense neutron star. It has been reported that all the three stars are packed within size smaller than the size of Earth's orbit around the Sun.

The best thing that helped scientists in concluding their research is the closeness of the stars because of which they have been successful in calculating accurate measurements of the system's complex gravitational interactions.

Scientists using Sound Waves to Suspend Objects in Mid-Air

Scientists using Sound Waves to Suspend Objects in Mid-Air

It has been reported that scientists have been successful in performing various experiments with the application of ultrasonic sound waves. According to a new report, scientists are making use of sound waves to suspend materials in mid-air.

In a recent experiment, Tokyo researchers used four panels of speakers facing each other, which combines to create 'ultrasonic focal point'. These focal points are adjustable by adjusting the output from each speaker array that is placed in about 21 inches wide area.

Jupiter-Bound Juno Spacecraft Recorded Video of Earth-Moon System during High-Speed Flyby

Jupiter-Bound-Juno-Spacecraft

A video of the Earth-moon system has been recorded by NASA's Jupiter-bound Juno spacecraft at the time of high-speed flyby in October. The video reveals about an extraordinary view of the two worlds that are bounded in a cosmic dance against the dark chasm of space.

These images were taken by a low-resolution camera that is mounted at the end of one of three solar array wings of the Juno spacecraft.
