We Are the World Music Video - Haiti Tribute

The song ‘We are the World’ was originally written to raise awareness for famine victims of Africa. Composed 25 years ago by Lionel Richie and Michael Jackson, this song topped the music charts across the world. The last recording date of the song was held on February 28, 1985 and on March 7, 1985, the song was released worldwide.

This year, ‘We are the World’ was revived to initiate a fundraising activity for Haiti earthquake victims. This time, the song was sung by over 70 stars and singers which include Celine Dion, Barbara Streisand, and Justin Bieber. Justin sang the opening of the song with a very cute voice quality. There were also parts of the music video wherein Michael Jackson’s original rendition was incorporated.

Some famous stars I know who were in the music video are Josh Groban, Carlos Santana, The Jonas Brothers, Nicole Scherzinger, Mary J. Blidge, Miley Cyrus, Enrique Iglesias, Jamie Foxx, Pink, and Jennifer Hudson. For me, the revival of the song was a great masterpiece by the producers and the artists who took part in making the music video.

To know more and help Haiti earthquake victims, just visit ‘We are the World Foundation’ website. To donate $ 10, text ‘WORLD’ to 50555 or buy this song at the iTunes store.

Gliese 581 c, d, and e - Possible Habitable Planets

Just 20.3 light years away from earth lay a red dwarf star as old as our own sun named Gliese 581. This star has planets of its own and is the 87th closest star system next to our sun. The Gliese 581 star system is believed to have four planets; Gliese 581 b, c, d, and e.

Most extra solar planets found by astronomers are closely the size of Jupiter or a lot bigger but Gliese 581c is just one third of the earth's size which means that the planets' gravitational force is just similar to that of our own. Gliese 581c lies in a belt called the habitable zone, an area around a certain star which enables water to be in its liquid form.

Gliese 581c is believed to have a runaway greenhouse effect and is more similar to Venus rather than earth. Just within the border of the habitable zone is the Gliese 581d which is roughly 7 to 14 times the size of the earth. Because it is in the habitable zone, water in this planet could be in liquid form and therefore, life could possibly exist.

In April 2009, astronomers found out that a planet which they named Gliese 581e in the same star system exists and has the size roughly close to earth. So far, this planet has the size closest to that of the earth than any of the extrasolar planets discovered.
