For the first time, astronomers have mapped clouds around a planet 
beyond our solar system - a giant sizzling, Jupiter-like world. The 
planet, known as Kepler-7b, is marked by high clouds in the west and 
clear skies in the east, astronomers, using data from NASA's Kepler and 
Spitzer space telescopes, found.
<br />
Previous studies from Spitzer have resulted in temperature maps 
of planets orbiting other stars, but this is the first look at cloud 
structures on a distant world. 
<br />
"By observing this planet with Spitzer and Kepler for more than 
three years, we were able to produce a very low-resolution 'map' of this
 giant, gaseous planet," said lead author of the study Brice-Olivier 
Demory of Massachusetts Institute of Technology in Cambridge.
<br />
"We wouldn't expect to see oceans or continents on this type of 
world, but we detected a clear, reflective signature that we interpreted
 as clouds," said Demory.
<br />
Kepler has discovered more than 150 exoplanets, which are planets outside our solar system, and Kepler-7b was one of the first.
<br />
Kepler's visible-light observations of Kepler-7b's moon-like 
phases led to a rough map of the planet that showed a bright spot on its
 western hemisphere. But these data were not enough on their own to 
decipher whether the bright spot was coming from clouds or heat. The 
Spitzer Space Telescope played a crucial role in answering this 
question.
<br />
Spitzer's ability to detect infrared light means it was able to 
measure Kepler-7b's temperature, estimating it between 815 and 982 
degrees Celsius.
<br />
This is relatively cool for a planet that orbits so close to its 
star - within 0.6 astronomical units - and, according to astronomers, 
too cool to be the source of light Kepler observed.
<br />
Instead, they determined, light from the planet's star is bouncing off cloud tops located on the west side of the planet.

New Delhi, Oct 1: In a serious case of security concerns in 
prisons, the Intelligence Bureau (IB) on Tuesday issued an alert that 
the home-grown terror-outfit Indian Mujahideen (IM) may try to free 
jailed operatives.

<br /><br />According to reports, the IB has issued alert to six jails across India.

It has said that national capital's Tihar jail and jails in Mumbai, Pune
 an Jaipur are on IM's target.

Today, in a major security lapse, seven convicts including six SIMI 
activists managed to escape from the Khandwa jail in Madhya Pradesh.

<br /><br />The seven prisoners reached the jail bathroom and stabbed the two 
security guards as they snatched their rifles. They then broke the wall 
of the bathroom and escaped.

Last month in a similar incident, an IM operative Afzal Usmani escaped 
while he was being taken to MCOCA court from Taloja Jail along with 22 
others by the Mumbai police.
<br /><br />
Although, a massive manhunt was launched to nab Usmani, but he still 
remains at large.

On one hand, the intelligence agencies, after a long hunt, caught two 
top IM operatives - Yasin Bhatkal and Abdul Karim Tunda and at the same 
time, the lack of security measures in prisons has raised a question 
mark over handling of terror suspects.<br /><br /> </div>
