The problem went away

Disputed island disappears into sea

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.

Happy Lady Ada Day!

Today is Ada Lovelace Day

In accordance with the Pledge, I would like to recognize the work of Margaret Geller . She and John Huchra discovered the Great Wall. This is one of the largest objects in the universe: Over 500 million light years long. That is 5,000 times the diameter of our entire galaxy.

My contribution last year is here.

Soviet Memorials on the Moon Honoring Women

From Universe Today:

Emily Lakdawalla from the Planetary Society uncovered an interesting tidbit about the Lunokhods which she generously passed on to me. After a little research, I found out more about an “extracurricular activity” the two Lunokhod rovers were commanded to do along their traverses on the lunar surface. They each created “memorials” to women on the Moon.
