Sunset Planet Alert
March 31, 2010: The solar system's innermost planets are about to put on a beautiful show.
This week, Mercury is emerging from the glare of the sun and making a beeline for Venus. By week's end, the two planets will be just 3o apart, an eye-catching pair in the deep-blue twilight of sunset.
The best nights to look are April 3rd and 4th. Go outside at the end of the day and face west. Venus pops out of the twilight first, so bright it actually shines through thin clouds. Mercury follows, just below and to the right: sky map.
Right: Venus and Mercury converging over Saitama, Japan, on March 30th.

Why is there a debate...AP Article

NEW DELHI – For nearly 30 years, India and Bangladesh have argued
over control of a tiny rock island in the Bay
of Bengal. Now rising sea levels have resolved the dispute for
them: the island's gone.
New
Moore Island in the Sunderbans has been completely submerged,
said oceanographer Sugata Hazra, a professor at Jadavpur University in Calcutta. Its
disappearance has been confirmed by satellite imagery and sea patrols, he said.
"What these two countries could not achieve from
years of talking, has been resolved by global
warming," said Hazra.
Scientists at the School of Oceanographic Studies at
the university have noted an alarming increase in the rate at which sea
levels have risen over the past decade in the Bay of Bengal.
Until 2000, the sea levels rose about 3 millimeters
(0.12 inches) a year, but over the last decade they have been rising
about 5 millimeters (0.2 inches) annually, he said.
Another nearby island, Lohachara, was submerged in
1996, forcing its inhabitants to move to the mainland, while almost half
the land of Ghoramara island was underwater, he said. At least 10 other
islands in the area were at risk as well, Hazra said.
"We will have ever larger numbers of people displaced
from the Sunderbans as more island areas come under water," he said.
Bangladesh, a low-lying delta nation of 150 million
people, is one of the countries worst-affected by global warming.
Officials estimate 18 percent of Bangladesh's coastal area will be
underwater and 20 million people will be displaced if sea levels rise 1
meter (3.3 feet) by 2050 as projected by some climate models.
India
and Bangladesh both claimed the empty New Moore Island, which is about
3.5 kilometers (2 miles) long and 3 kilometers (1.5 miles) wide.
Bangladesh referred to the island as South Talpatti.
There were no permanent structures on New Moore, but
India sent some paramilitary soldiers to its rocky shores in 1981 to
hoist its national flag.The demarcation of the maritime boundary — and who
controls the remaining islands — remains an open issue between the two
South Asian neighbors, despite the disappearance of New Moore, said an
official in India's foreign ministry, who spoke on condition of
anonymity because he was not authorized to speak on international
disputes.
Bangladesh officials were not available for comment Wednesday.
