Goldilocks "Earth-Like" Planet Found?

Artist's impression of the extrasolar planet O...Image via WikipediaAstronomers 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.

Astronomy History: 400 years ago

Yesterday, August 25, marks the 400th years from the time that an Italian mateghematician in the name of Galileo Galilei focused the telecope into the heavens. This momentous event opened the way to new understanding of man's position in the universe.

Galileo observed many fascinating sights. One is the geography and topography of the moon,

 its mountains , valleys and craters. He also saw the phases of Venus, which proved to be an evidence of Corpernicus' heiocentric universe model. He saw the giant planet Jupiter along with it's four large moons-Ganymede, Io, Callisto, and Europa.

Galileo immediately announced this newly found truth about the sun being the center of the universe, but the Catholic Church's support of Geo-centric universe never changed. Instead,

If Galileo was still alive today, he would have been very happy about the dramatic increase of knowledge and understanding of the universe compared to his days. But even today's knowledge about the universe is only a scratch of the things yet to be discovered.

Pluto-Failed Planet?

Pluto still failed to be recognized as a planet after this week's international astronomical meeting held by the International Astronomical Union (IAU) in Rio Janeiro. We can still recall the controversial move made by the IAU to demote Pluto as a "dwarf planet" three years ago in the same meeting held in Prague. The world witnessed table bangings and walk outs of some astronomers after the decision has been laid down.

The decision was based on the fact that it failed to pass the criteria to be major body on it's orbit. Pluto's mass only accounts for 0.07 of the entire mass of all objects in its orbit (which includes gas giant Neptune because their obits intersect). In contrast, earth is more than a million times heavier than all the objects on its orbit (which includes the moon).

Pluto joined the group of the dwarf planets that includes Ceres, Haumea, Makemake, and Eris.

Astronomy in the Philippines

Astronomy is one of the basic sciences that were still unexplored here in the

Philippines. Some may not agree with this statement especially those who are “knowledgeable” about astronomy. But I was actually pertaining to its popularity or awareness of Filipinos about this body of knowledge. For example, the difference between information technology and astronomy is quite big.

Granted, the importance of astronomy in the Philippine setting is quite low. I think that it was the reason why no one (or maybe few) in the government ever focus its attention in improving the awareness of the people. And I definitely agree that the government faces even more important problems that need their full focus.

PAG-ASA

The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAG-ASA) is the sole government entity who is commissioned to provide awareness to the people about astronomy. Sadly, due to more important priorities like weather and other natural disasters occurring in the country, it only focuses its limited budget to weather forecasting. Again, I totally agree with them. It’s the right thing to do.

Though astronomy in the Philippines is generally poor, there are still reasons to rejoice. Though lacking unity, there are a lot of scattered private organizations in the country that promote awareness about the science of heavenly bodies. These groups consist of professional and amateur astronomers, students, and other astronomy enthusiasts. It’s very nice to know that the interest of the Filipinos on astronomy is not absolutely empty.
Also, the Rizal Technological University of the Philippines (RTU) became the first educational institution to offer the first ever astronomy college course in the country. Though the initial enrollees on the Bachelor of Science (BS) in Astronomy Technology are just few, it is a signal that the celestial science in the country is off to a good start. They also offer Masters of Science in Astronomy for those who want to take up Masters Degree.

Authors Note

It seems like astronomy in the Philippines is getting the right push. This year 2009 was declared as the International Year of Astronomy (IYA2009). Its mission is to help the citizen in the world (including us, Filipinos) rediscover its place in the universe through day and night time sky and thereby engage a personal sense of wonder and discovery. It’s very nice to know that the Philippines is one of the active nations on the program 100 Hours of Astronomy (100HA).
Yes, though it may not have direct effects as other sciences have on Filipino lives, no one could dispute the fact that astronomy has an impact on the world we live in.
This blog is dedicated to provide some ideas on astronomy not only in the Philippines but on the entire globe.

2009-International Year of Astronomy

2009 is the International Year of Astronomy. This is also the year I decided to come back to who I am ten years ago.

The heavens is calling me back...I cannot refuse...



Please join me in rediscovering the fantastic world of astronomy. Let's explore the universe and be drowned with awe and reverence to its Creator.
