Goldilocks "Earth-Like" Planet Found?

Artist's impression of the extrasolar planet O...Image via Wikipedia
Astronomers recently found a planet outside the solar system with conditions they termed as "Goldilocks", neither too hot nor too cold. This they said was the perfect condition for a great possibility of extra terrestrial life. The planet is named Gliese 581g is found to be circling a red dwarf star located 120 trillion miles from the Earth.

The planet is a few times larger than the earth and scientists estimate that the mass and gravity of the planet is just comparable to the earth. the planet is also tidally locked to its parent star which means that only one side faces the star. This condition will lead to a very hot condition on the portion directly facing the star and an icy condition on the other side. The interesting part though is somewhere in the middle of the two faces of the planet where the temperature may be just right for a habitable zone.

SCAM: My First Scam Text This Year; 850000 Pesos from GMA Kapuso Foundation

It's a brand new year for everyone, including local scammers. And despite all the efforts by PLDT and Globe Telecom to curb text message scammers, from time to time, they still creep out and show up in our inboxes.

How Much Does a MRI Scan Costs in the Philippines?

My dad recently needs to have a Magnetic Resonance Imaging (MRI) scan for his prostate problem. So I made a little research on how much does it cost to have one. Well, turns out, it depends on many factors such as which part of the body is to be scanned. There's also this technique called "MRI with contrast" wherein the patient will be injected with a chemical to make the scan clearer. For your information this technique of adding contrast is know as Gadolinium Contrast Medium . It adds cost to the procedure but with more clarity, the more you can trust the diagnosis.

We got it in i-Scan Healthcare Inc here in Quezon City. The cost is 13000 Pesos . Please take not that the amount was just for the scan and the result will be read by a separate professional. Some la
