Study: 'Curtain eruptions’ of water vapor noticed on Enceladus’ surface

According to a new study published in the journal Nature, 'curtain eruptions' of water vapor have been noticed on the surface of Saturn's sixth-biggest moon, Enceladus. The study claims that water-vapor eruptions on Enceladus are seemingly in the form of curtain-like sheets, instead of distinct jets.

CO2 atmospheric levels reached new heights in March: NASA

CO2 atmospheric levels reached new heights in March: NASA

Dangerous global warming is going to be a really big trouble soon as the atmospheric levels of the gas reached new levels in the month of March this year, the National Aeronautics & Space Administration (NASA) warned. While providing information on the issue, Michael Gunson, the head of NASA's global change and energy program, said, the 400 mark has suggested that life on earth is moving towards the mark of 450 ppm. The world is speeding up the rate of accumulation of carbon dioxide. There is no indication that the rate is slowing down.

Cosmic ‘halo’ around Andromeda Galaxy is more massive than previously thought

Cosmic ‘halo’ around Andromeda Galaxy is more massive than previously thought

The giant halo of cosmic gas that surrounds the Andromeda Galaxy is much more massive than previously estimated, scientists concluded after analyzing data gathered by NASA's Hubble Space Telescope. The astronomers found that the gas enveloping our nearest massive galactic neighbor is about six times larger and 1,000 times more massive than previously measured. This recent finding promises would reveal more clues about the evolution and structure of majestic giant spirals, one of the most common types of galaxies in the universe.

SpaceX tests Dragon crew capsule for first time

SpaceX tests Dragon crew capsule for first time

Private-sector space firm SpaceX tested its Dragon crew capsule for the first time at Cape Canaveral on Wednesday this week. However, the Dragon capsule didn't go into the space. The 99-second test flight was conducted to check the capsule's crucial safety mechanism.

The test flight was conducted for almost 99 seconds to check the crucial safety mechanism that would save astronauts in case of a catastrophic rocket failure.

Scientists detect curtain vapor eruptions on Saturn’s moon Encedalus

Scientists detect curtain vapor eruptions on Saturn’s moon Encedalus

Vaporous eruptions on the surface of Saturn's moon Encedalus may be taking the form of elongated curtains of vapors rather than discreet spurts, NASA scientists said. The scientists reached the conclusion after analyzing data collected by the American space agency's Cassini spacecraft.

Data sent by NASA's Cassini spacecraft helped the researchers understand that there are higher chances for creations of phantoms by an optical illusion. Until now, they appeared to be individual jets of vapor along the length of fissures on the moon's surface.

Russia’s unmanned cargo ship burns up as it re-enters Earth’s atmosphere

Russia’s unmanned cargo ship burns up as it re-enters Earth’s atmosphere

Russian space agency Roscosmos confirmed that the unmanned cargo ship that was launched from Kazakhstan on April 28 went out-of-control and burnt up as it re-entered Earth's atmosphere. The spacecraft re-entered over the Pacific, but only a few pieces were expected to enter into the sea. The Progress M-27M was loaded with more than three tonnes of supplies to the International Space Station. It was carrying food, water, fuel, oxygen and clothing for the crew of six people on the ISS.

Erratic Temperature Changes Hint at Volcanic Activity on Super-Earth

Erratic Temperature Changes Hint at Volcanic Activity on Super-Earth

First detected in 2004, the super-Earth, 55 Cancri-e as it is called, has taken astronomers by surprise owing to the wild temperature changes ranging from 1,000 to 2,700 degrees celsius. The reason cited for these dramatic changes is intense volcanic activity on the planet’s surface.

NASA’s Messenger Spacecraft crashes into Mercury’s Surface; End of 11-year Journey

NASA’s Messenger Spacecraft crashes into Mercury’s Surface; End of 11-year Journey

NASA’s Mercury-orbiting spacecraft, Messenger, crashed into the surface of the planet as scientists had planned the end of its historic 11-year mission on Thursday. When Messenger hit the Mercury’s surface at 3:26 pm ET, it was traveling at the speed of about 8,750 mph, said NASA. The impact was so strong that it created a new crater on the planet’s surface.

The end of operations was confirmed by mission control at 3:40pm ET. No signal was detected by NASA’s Deep Space Network (DSN) station in Goldstone, Calif., after Messenger crashed into the little planet closest to the sun.
