Volcano Eruptions Can Pause Global Warming

November 20, 2014 By Deborah Nielsen Leave a Comment

Volcanic eruptions from Iceland to Alaska play a vital role in the reduction of global warming.

A recent study demonstrated that small volcanic eruption expelled a large amount of sulfur dioxide gases into the top layer of Earth’s atmosphere. This particular action has decreased considerable amount of global warming in the last few decades.

Earlier, researchers proposed that minor outburst plays a less part in the global warming hiatus. The Global warming hiatus is a time period in which average surface temperatures experience a slight change. Generally, this phenomenon is known as global warming pause or global warming slow down.

However, latest ground, air and satellite measurements propose that the last volcanic eruption have averted almost twice the amount of solar radiation.

David Ridley, the lead author of the study informed that the impact of smaller volcanoes is a natural solution to the warming hiatus. Nowadays, these eruptions occur more regularly as compared to the previous decades.

The year 1998 is marked as the warmest year in the history. Nonetheless, current years are relatively warmer than the 1998 but still the unreasonable global warming descended to a great extent.

The decrease in temperature has really baffled climate scientists. A few researchers believed that the Atlantic and Southern Oceans absorbed the heat, which was responsible for global warming.

The Massachusetts Institute of Technology conducted this study. Later on, the report is printed in the American Geophysical Union

Meteor Shower Changed Martian Atmosphere

November 10, 2014 By Brian Galloway 4 Comments

Last month, Comet Siding Spring spawned several tons of dust and ice particles on the Red Plane. The incident produced an approximately thousands of shooting stars.

Recently, NASA accumulated data from two of its spacecrafts that revealed significant information which gave an insight about the structure of Comet Siding Spring and the atmosphere of Mars.

The data unveiled that the large amount of dust and other fragments changed the entire configuration and released a meteor shower. Later on, the meteor shower gave birth to several atmospheric alterations.

Jim Green, the director of NASA’s Planetary Science Division informed that the scientists were really surprised by the large quantity of particles comet produced.

The magnesium break down the electric charge present in the Martian atmosphere. On the other hand, sodium formed a yellowish shade in the night sky that people usually witness in their parking lots at night.

Moreover, scientist asserted that this is the first time they observed this kind of ionization in the atmosphere because of any comet. It increased the layer of ions in the top most level of atmosphere. Some of the most noteworthy ions were sodium, iron and magnesium.

Nick Schneider, the main instrument scientist of one of the NASA’s satellite stated that it was indeed an amazing sight for the human eye.

The best place to witness this meteor shower was the Martian Surface. However, it was certainly impossible for experts to view the incident from there. Therefore, NASA sent two of its rover over there in order to record this amazing meteor shower. Unfortunately, the rovers failed to document the meteor shower due to some technical fault.

Study Reveals; Connection Between Spaceweather and Geomagnetic Storms

Researchers of the United States unveil some really significant information related to the physics of space weather. The information will certainly help the scientist to foresee dangerous “solar wind”.

The exact prediction of such kind of disaster will allow the entire man kind to create some measures to deal with them.

The researchers worked on this particular topic in order to present it in the American Physical Society’s Division of Plasma Physics annual meeting.

Experts concentrated on the hot, charged plasma gas that the sun explods into the space. The plasma gas covers the entire magnetic field of the planet Earth. This kind of wind can generate geomagnetic storms which can disrupt the entire cellular, satellite system and block all the power stations of this world.

Moreover, experts gave some insight on the magnetic reconnection which is known as “explosive Phenomenon”. The theory deals with the incident that occurs when a solar blaze comes in contact with the magnetic field of Earth.

In the laboratory of University of California Los Angles, a group of scientists examine the relationship between the plasma magnetic waves. This interaction of solar wind provides more details regarding the behavior of hot plasma.

A professor of Swarthmore College utilized the “wind tunnel” to speed up the signatures of solar wind’s magnetic turbulence.

At last, students of Columbia University along with their advisor make use of a chamber packed with plasma and magnetic fields. The compartment is specially designed like the Earth’s atmosphere. The study reveals a strong relation between local space weather and ionosphere currents.

New Satellite Snapshots Exposed Thousands Of Underwater Volcanoes of Ocean

October 4, 2014 By Germaine Hicks Leave a Comment

According to the recent reports revealed, Scientists have developed a novel map of the entire world’s seafloor, displaying a brighter image of the compositions that actually formed the cordial, least explored parts of the ocean. The study was published in the ‘Science’ journal.

The achievement was based on accessing 2 intact streams of satellite data, researchers claimed.

Novel map shows hundreds of unexplored mountains that are growing from the seafloor, named as seamounts. These seamounts are eventually appeared in the map, along with the novel hints of continents formation. The scientists have merged the existing data with the enhanced remote sensing instruments, which helps them to explore ocean expanding centers and small studies remote ocean basins.

In the meantime, the researchers mapped the earthquakes too and found that the seamounts and the earthquakes are connected often. These seamounts are once volcanoes and that is why researchers generally discovered nearby tectonically active plate boundaries, mid-ocean ridges and sub-ducting zones.

The novel map is as authentic as the previous one developed 20 years ago, researchers from California’s Scripps Institution of Oceanography (SIO) stated.

Don Rice, program director in the National Science Foundation’s Division of Ocean Sciences, which funded the research, said that, “the team of researched have developed a powerful tool in order to explore the regional seafloor and geophysical processes.”

The map, which was developed by using a scientific model in order to capture the gravity measurements of the ocean seafloor, also extracts data from the European Space Agency’s (ESA) CryoSat-2 satellite.

David Sandwell, lead author of the paper and geophysicist at SIO stated that, “Things you could see very clearly are the most common landform on the planet, named as abyssal hills.”

Furthermore the researchers said that, the map offers a window within the tectonics of deep oceans. Alternatively, this map also offers a base for the upcoming Google’s ocean maps version. Researchers believed that it would cover large voids between shipboard depth profiles.

In earlier times, undetected features include newly exposed continental connections across South America and Africa and new evidence for seafloor spreading ridges in the Gulf of Mexico. The ridges were active 150 million years ago and are now buried by mile-thick layers of sediment.

As per the official reports, India conquered its first ever inter-planetary mission of putting the satellite in to orbit around Mars on Wednesday. After the successful accomplishment of the mission, India is projected as an elite club of deep-space explorers.

The Indian TV has showed the live broadcast of the event. Researchers have welcomed with the wild applause while the engines successfully completed its burn-time of 24-mins to contrive the spaceship into its specified place around the red-planet.

Prime Minister Narendra Modi stated, “With the successful completion of this mission, we have moved afar from the border-lines of human enterprise and innovation.” He further congratulated the researcher for the accomplished mission and said, “We have steered our spaceship via route that is known to few.”

However, the scientist also explained the further stages of the Mars Orbiter Mission. They nicknamed the mission as MOM. After the successful mission of the space program, the scientist called it as a milestone in revealing that they can conduct more complex missions and operate as a global-launch pad for commercial, navigational and research satellites.

This was considered to be the major achievement for an under develop country like India who have 1.2bn people from which most are poor. Meanwhile it has good scientific and technical education system, which produced so many engineers, doctors, and software programmers every year.

India portrays MOM to be the first successful mission on Mars attempted by any under-develop country. Though, the ESA (European Space Agency), which is considered as the conglomerate of several nations, did its first Mars mission back in 2003.

On the other hand, China, which is a biggest rival of India, also, expanding its space exploration programs along with a space-lab in the orbit before the establishment of the permanent space-station.

No doubt, putting a spacecraft in to an orbit around Mars is not an easy task to do. Half of the World countries already had attempted out of which 23 missions have failed from the entre 41 missions. Indian named this spaceship as ‘Mangalyaan’ in Hindi, which means ‘Mars Craft’. Furthermore, India is expecting this spaceship to be a universal promotion for its ability in designing, preparation and managing a difficult, deep-space mission.

Though, India have already completed some of the successful missions of satellite launches involving transferring the Chandrayaan-1 lunar orbiter, which revealed key facts of water on the moon in 2008. Moreover, they are planning to send the Rover on the moon.
