Frozen Steller Twins Discovered: Orbits in Binary Star System

Pooja Kashyap

Lately a binary star system has attracted attention of many space scientists. This binary system consists of twin stars, mutually orbiting around a common center of mass. Situated around 3,000 light years away from Earth, astronomers’ expecting that it could shed some information regarding similar Earth like bodies floating in space. The planet weighs twice that of the Earth and orbits, in binary system, one star. Distance between the two corresponds to the distance between the Earth and the Sun. However, unlike the Sun, the planet’s host star is dimmer…

Titan’s Ice Shell overlies Salty Ocean: As Salty as Earth’s Dead Sea

Pooja Kashyap

NASA’s Cassini mission has given strong confirmation regarding the saltiness of Titan, the largest moon of Saturn. Space scientists have even compared the salt content with Earth’s Dead Sea. The result corresponds to 10 years observation, where Cassini was busy accumulating the gravitational and topographical data. Researchers organized this information and developed a model based on Titan’s structure. This resulted in gaining better insights of the moon’s exterior ice shell.

Kepler-10c the mega-Earth Discovered: Godzilla of Earths

Pooja Kashyap

Space scientists have discovered a new planet to which they call as “Godzilla of Earths”, maybe because of its rocky exteriors. The exoplanet weighs more than 17 times that of Earth. Until now researchers believe that the planet is all solid and is much gigantic with respect to previous discoveries of super-Earth, hence it falls into the casket of mega-Earth. Sasselov, one of the astronomers believe that Kepler-10c, the newly found mega-Earth, is high on probability with respect to implications for life.

10 Easiest Internet Tricks: Simplest Googling Tips to Remember

So here we go, 1) Downloading music Type the following snippet into the google search bar. It’ll give you music downloads…

Bright Points in Solar Atmosphere: Gateway to Sun’s Roiling Interior

Pooja Kashyap

NASA’s Solar Dynamics Observatory (SDO) has been able to collect data regarding the depth of the shining star, bright spots in the solar atmosphere and the strings of magnetic signatures observed on the surface of Earth. With this data, space scientists will get a peek into the insights related to the real-time mapping of the sun’s roiling interior. These understandings will help them on converging the decade long investigations of its 22-year sunspot cycle and emission of solar flares. As per Scott McIntosh, one of the lead researchers, this data…

Planet X and Nemesis Myth Debunked: WISE Survey

Pooja Kashyap

In an attempt to find the reasons, which led to the wobbly effect of Uranus’s orbit, researchers discovered other planets like Neptune and Pluto but there was no Planet X anywhere. Similarly, the hunt for Sun like star, Nemesis, which they claim might have wiped out the age of dinosaurs completely, is still a far-fetched dream. It’s been an effort of more than two centuries and now the researchers want to draw line to reach a conclusion.  Kevin Luhman an astronomer at the University of Pennsylvania asserted that there are no such…

First Lunar Laser Communication Demonstration Goes Successful

Pooja Kashyap

Researchers from NASA and MIT have been trying to create a two-way laser link communication between the Moon and the Earth. The effort has been initiated last year in the month of Oct. First step concluded by beaming of laser light from a spacecraft orbiting the moon to the earth, at White Sands, New Mexico. And then the beam was sent to the spacecraft from the lab and this process went for about a month. Space scientists have dubbed it as Lunar Laser Communication Demonstration (LLCD). The entire mechanism went…

Satellite Servicing: Refueling Missions versus Resurrecting Satellites

Pooja Kashyap

Satellites do not know concepts like repairing or re-fueling. Once they are put into orbit, they last until the task is completed and then de-orbit. In case of malfunctioning, they are just forgotten about and are left to contribute to space junk. So what exactly would robots in manned cosmonautics do, although researchers envision that the bots would help in repairs and maintenance at the ISS along with other things including minimize human work. Interestingly, DARPA is trying to resurrect the ‘dead’ satellites by imparting the required skills to its…

Mars Once Had Pools Of Fresh Water

Neha Shukla

The red planet had fresh water puddle on its surface around 4 billion years ago, as revealed by NASA Mars Opportunity Rover upon analyzing some of the oldest minerals. The same facts have been confirmed by the Curiosity, the newcomer collecting data on the other side of the planet. Planetary scientist Ray Arvidson, with Washington University in St. Louis said,the pool of water was so fresh that could have sustained all life forms. 

Tardigrades Might Help Humans In Developing Space Ecosystem

Neha Shukla

Tardigrades (also known as waterbears) are the toughest organism capable of thriving in the most unfavorable conditions on earth and even in the outer space. Tardigrades have been found living in low temperatures (just above the absolute zero), high temperatures (above boiling point of water), can bear high pressure, high ionizing radiations and can even exist in the vacuum of the space. And because of this unique survival skill of the organism, the scientists have classified them as extremophiles i.e. an organism capable on living in the harshest of conditions,…

Europa, Jupiter’s Moon Is Spewing Off Water Vapour

Pooja Kashyap

Latest finding put forth by NASA’s Hubble Space Telescope has confirmed that Europa, Jupiter’s moon, is ejecting water vapour. Its surface consists of water ice and has one of the finest gradients in the Solar System. This has led to a conceivable notion that there might exist water ocean underneath. As per the space scientists, this sign might give rise to a possibility of habitability. The discovery that water vapour is ejected near the south pole strengthens Europa’s position as the top candidate for potential habitability. However, we do not…

Meet Valkyrie, Johnson Space Center’s New Super Hero

Pooja Kashyap

NASA’s Johnson Space Center (JSC) in association with the University of Texas and Texas A&M and with funding from the state of Texas itself have built a humanoid to which they call, Valkyrie, officially designated as “R5”. The bot is 6.2 feet tall, weighs around 125 kgs with 44 degree of freedom and is powered by battery. The machine is not built for any space mission or otherwise but for the DARPA Robotics Challenge (DRC), that’ll hold its first round of competition in the second half of this month.

Newly Discovered Sound-Producing Organ in Koalas

Wa'd Abuzurayk

“Cute” is a word usually associated with Koalas. However, these small sized bears have been recently discussed from an angle distant from that related to their scrumptious looks; one that uncovered the mystery of their deep voices. Koalas have always puzzled scientists with their low-pitched bellows, which are considered about 20 times lower than they should be considering their body sizes. This estimation was made considering that the size of the vocal cords of an animal determines the pitch of their voices. Accordingly, smaller-sized animals are known to produce higher-pitched…

Giant Convection Cells Observed Within Sun

Pooja Kashyap

We have known that convection currents are a part of the water cycle on earth. A conventional cell – density differences that results from rising and/or falling of currents – is the spark that ignites the formation of clouds with its release and transportation of energy. As air transcends along the surface of the earth, it carries heat, hence loses density (because of fluid dynamics) and moves higher into the atmosphere. Upon reaching there, it experiences low pressure due to which fluid retention becomes difficult and so it releases its…
