Professor Michel Mayor, the scientist who led the team that identified the first extrasolar planet in 1995, believes a planet similar in size and composition to Earth will soon be found.

Prof Mayor, of Geneva University, said that the prospect of finding a planet habitable for humans had come a step closer through rapid technological advances allowing observation of planets outside the solar system.

Addressing a Royal Society conference to mark the 50th anniversary of the Search for Extra-Terrestrial Intelligence (SETI) programme, he said: “The search for twins of Earth is motivated by the ultimate prospect of finding sites with favourable conditions for the development of life.

The mammoth chunk of ice, which measures 12 miles long and five miles wide, was spotted floating close to the mainland by scientists at the Australian Antarctic Division (ADD).

Known as B17B, it is currently drifting 1,000 miles from Australia’s west coast and is moving gradually north with the ocean current and prevailing wind.

Planets circle the stars that dot the heavens.

Before 1995, we couldn’t have said that with any certainty. Now we know of more than 300 planets orbiting distant stars, and we have a fleet of telescopes looking for them. The ultimate goal is to find another Earth orbiting a star like the Sun, but the quest on the way to that Holy Grail has yielded some strange benchmarks.

Meet the planet COROT-exo-3b. It orbits a star slightly larger, hotter, and brighter than the Sun. The star is not an unusual one in any way, but the planet is definitely weird: it orbits the star in just over 4 days, which is pretty close in, though not a record breaker in and of itself. What’s bizarre is that it has about the same diameter of Jupiter, but has 21.6 times Jupiter’s mass. That makes it denser than lead.

If I could stand on the surface of this planet, I’d weigh 4200 kilograms*. That’s over 9000 pounds! Read the full story

BANGALORE: After water, it’s magnet . Chandrayaan-1 has discovered and confirmed for the first time the presence of magnetic spheres on the side of the moon—the side we cannot see from the earth. This could theoretically mean a longer and secure stay for astronauts on moon.

There had been speculation for long but the confirmation was made by Sara, the instrument jointly made by Isro, European Space Agency and Sweden. The findings by Sara, not yet published, were made known by top scientists on the sidelines of the platinum jubilee celebrations of the Indian Academy of Sciences at IISC. The discovery of magnetic forces comes after the discovery of water molecules by M3—the Nasa instrument on Chandrayaan-1. Read the full story
