NASA has released very detail night images of Earth. The images is a composite of cloud-free photos captured with the help of a sensor on the NASA-NOAA Suomi National Polar-orbiting Partnership (NPP) satellite that launched last October. The NPP orbits the Earth 14 times each day at an altitude of about 500 miles.
This is a new single shot image of Earth taken 22,369 miles away by the Russian weather satellite Elektro-L No.1. This Earth photo is very different to any you have seen before as the satellite uses visible and infrared wavelengths of light to gather the colours.
Researchers have discovered an extrasolar planet Gliese 581g that could harbour life, found within the constellation of Libra. The researchers are Steven Vogt of the University of California and Paul Butler of the Carnegie Institution in Washington.
Astronomers said they had discovered a planet GJ 1214b composed mostly of water and it is the most Earth-like planet ever found outside our solar system.
David Charbonneau of the Harvard-Smithsonian Center for Astrophysics said, It’s basically one big ocean. This is a next-door neighbor. For perspective, our own TV signals have already passed beyond the distance of this star.
The large asteroid Apophis was discovered in 2004 with the size of 2 football fields is said to hit earth on April 13 2036. But recent research from NASA indicated that it has only a very slim chance of impacting into Earth.
Earth can now relax. Scientists have recalculated the asteroids path and it is slated to come within 18,300 miles above Earth’s surface in 2029.
Scientist has found Gliese 581d, 1.9 times size of Earth, has a lot more in common with our planet than astronomers first thought. Michel Mayor, an astrophysicist at Geneva University in Switzerland said, The Holy Grail of current exoplanet research is the detection of a rocky, Earth-like planet in the ‘habitable zone,’
It is said that Gliese 581d could even be covered by a large and deep ocean and it is the first serious ‘water world’ candidate.
