Presence of water on Mars has been always a topic of discussion for the researchers. Even though it is still not confirmed, whether the Red planet ever possessed water. Since 2011, peculiar strips (possibly water) have been noticed to appear and then disappear from the planet’s surface. Lujendra Ojha, the then scholar at the University of Arizona, first discovered these mysterious strips.

After several years of consistent hard work, researchers from Brown University were able to complete the first global gelological map of Ganymede, Jupiter’s largest moon, which is also largest in the solar system. Geologists envision that the map might assist in future exploration since they expects habitable environment upon Ganymede. The moon’s terrain and the possibility of underground waters have made it a subject of curiosity and investigation by the researchers. Voyager and Galileo spacecraft were used to take images for constructing the map. In 1979, Voyager made its first…

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.

Travelling to space can have an adverse effect on the immune system. Researchers at University of California Davis College of Biological Sciences and lead by Deborah Kimbrell, found that the fruit flies (Drosophila flies) born and raised in a spacecraft has weak immune system in fighting commonly occurring fungus. The researchers choose Drosophila flies for the fact that they share many basic features of their defense mechanism with those of mice and humans.

Recent research claims that planet Mars might act as an enormous gas pump with its low atmospheric pressure and porous soil making the assertion strong enough to prove the hypothesis. Space scientists have already advocated the constant activity that is going on the surface like dust storms and drifting dunes. And now, the new study holds the certainty of having a similar kind of motion underneath the surface as well. With this assertion, the planet becomes the solar system’s first such body in which continuous pumping on a massive scale…

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…

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…

Recent discovery of planet HD 106906 b has exploded the underlying hypotheses of planet formation so far. A team of space scientists led by a University of Arizona graduate student has pioneered the discovery. The exoplanet weighs around 20.9x 1027 kg, which is eleven times more than that of Jupiter. It’s also found revolving around its star at 650 times the average distance between the Earth and the Sun. As per one theory of planet formation, planets that are in proximity with their stars band together with the help of…

Two teams of space scientists have discovered the presence of atmospheric water across the five distant planets. NASA’s Hubble Space Telescope was the tool employed by the teams for the exploration mission. WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b were the planets that were under observation. WASP-17b and HD209458b gave the strongest signal of water content present in their atmosphere while the others showed consistency.

Researchers and scientists are always curious to find life on other planets and tries to find whether other planets could ever sustain life. NASA is trying to find an answer to one such question and is planning to grow plants on moon, with the assistance of a robot, few cameras and thousands of schoolchildren. In 2015, a group of NASA scientist named as The Lunar Plant Growth Habitat Team, along with volunteers, contractors and students will be trying to bring life on other planet, which has been never attempted so…

After travelling for over a million years, Comet ISON or Comet Nevski–Novichonok, a sungrazing comet discovered on 21 September 2012 by Vitali Nevski and Artyom Novichonok will be completing its inward journey through the solar system by the Thanksgiving Day, that is, Nov. 28, 2013. Researchers feel that either it will shatter due to the extreme heat of the sun or speeds back, never to return. Space scientists were intrigued since the time they had discovered the Comet ISON (in Sept 2012) because they believe that the comet consists of…

Interplanetary dust or the Cosmic dust has occupied space in the solar system. Studies are still being conducted in order to understand the nature, origin and its relationship to larger bodies in space. However, one thing is confirmed that a planet’s gravity is acting on the cosmic dust by pulling it into its orbit forming a ring of dust around itself. Earth too has been travelling in the ring of dust, a discovery that was made twenty years ago. Since then space scientists have been working upon gathering the information…

Every time one reads a philosophical novel, one finds a new motif running parallelly across the main theme and the numbers of motifs keep on increasing with the number of times the book is re-read. Expedition on Mars is quite similar to such an experience or a discovery at least I think so. Until now, researchers advocated that Mars is much simpler geologically with respect to Earth and that the planet’s surface consists of only basalt, dark-colored volcanic rocks. However, a recent discovery by the Curiosity rover has surfaced more…

It’s been quite a sometime since scientists were working towards obtaining insights and control over the occurrences and patterns of global wildfire. As per a research reported by Clark University geographers, carbon emissions from fires have escalated tremendously, between 1996 and 2008 is 2.4 times as much as what burned between 1984 and 1995. So in order to resolve the problem, scientists thought of having a dedicated geostationary satellite. Such technology would also help in averting catastrophes like Arizona’s Yarnell Fire, which killed nearly 19 Firefighters in US this summer.…

Planets scientists’ have discovered carbonation in a meteorite that landed on earth, US to be more specific, in late back 1931. Meteorite study suggests that it must be 3,000 years old and is carried off from the surface of Mars. This asserts that the surface on Mars must be loaded with carbon dioxide, which had happened not more than 3 to 4 billion years ago. Researchers still have no argument which supports the reason for its current absence. However, they have postulated several reasons that might have lead to the…
