Anything about astronomy.
I am personally not knowledgeable, but I frequently find articles about astronomy fascinating. I'll just post any interesting stuff I may find here.
Feel free to discuss, or even philosophize.
Just don't post about UFO sightings and alien conspiracy theories.
interesting thread... maghintay muna ko ng musings ng ibang tao. wala akong idea kung ano ipo-post e.. hehe
Has anyone ever seen one of our neighboring planets in real life? Ako hindi pa. :(
^Venus and Mercury are sometimes visible when the first light of sunset and sunrise hits the dark sky. :D
^ let me add Jupiter and Mars. :-)

di ko pa ito nakita doc.
pero i once spotted Saturn near the constellation Libra.
OT: iba pumasok sa isip ko when i read heavenly bodies. sorry medyo tinotopak hahaha
So how do you know na planet ang nakikita mo, not a star? And how do you locate them?
Remember the smiley sky last year (ata)? One of the eyes was Jupiter. :-)
Mars can be seen in the Philippine night sky around the month of August. It's your month Luc. :-)
^planets move. stars don't. no, you won't see them move right away, there are certain days (for fast planets like venus and mercury) and certain months (slower planets) that they are not in location. and in as much the same, we are supposedly able to view a certain sky on a certain season. this is more applicable to other hemispheres kc sa tropics, more or less magkaparehas lng sky natin the year round.
^^ not all the time. :-) they move because they have orbits. hehehe.
Hmm parang di pa ako nakakita ng Mars din. Madali lang ang Venus ma spot. It's that brightest "star" in the morning at a very small angle near the sun. Mercury is near venus. It's smaller and nearer to the sun. By daytime, di mo na sila ma-appreciate.
Planetary alignment is a phenomen. I'm not sure when that last happened, but people of different race and religion relate it to a great omen. I didn't really bother searching more on that.
hehehe.
when i was younger, gradeshool siguro ako nun, i have with me a sky map - constellation, stars and planets, na lagi kong ginagamit almost every night para mag observe sa night sky. mas visible kasi ang night sky sa province kesa dito sa manila.
^that is so true doc. if there's one thing i really love about the province, it's their night sky, where it's clearer and far from the bright lights of the city. you see more stars that way.
nung 1st yr college ako, muntik na akong sumali ng isang astronomy club dito sa cebu, parang sister club lang ng Ateneo Astronomy club sa manila. kaso di ako natuloy.

parang AstroSoc ng UP? cool. I joined that org in college. Nyahahaha.
Parang ganon nga doc. Wala kc ganyang club sa college na pinapasukan ko, pero yung friend ko sa Ateneo niyaya nya akong magjoin kc daw may real passion ako noon di tulad ng iba daw na sumasali lang para cool points.
Matagal na din yun, ngayon iniisip ko lang yan pag may pagkakataon ako makapag-stargazing.
One of the amazing events that I look forward to in the night sky ay yung mga meteor showers. :-) Kahit mahirap dito sa Manila, I really try and do my best na maka-witness. :-)
Mahirap dyan sa city doc! Sa province mo yan pinapanood napakaganda daw. Pero di ko pa nawitness ito sa province din. x10 showers ang difference daw.
At a clear night, I always find time to spot Betelgeuse and Rigel in Orion. :)
^^ yeah!!! Betelgeuse and Rigel in Orion!!! :-)
x10? Ganun kalaki ang difference?
yep! i hope i'll get the chance to see one someday too.
I find it cool that as one of the biggest stars out there, Betelgeuse and Rigel are in the same constellation. :)

Gusto ko makakita ng moon bow. :D
@fox: Thanks. I just think this will be a unique thread. Parang never pa ako nakakita ng thread about astronomy sa ibang forums.
@marvin: Sorry, meron na tayong Aliens (http://www.pinoyguyguide.com/forums/index.php?topic=1410.0) thread, dun nalang yung mga about aliens and conspiracy theories.
what bout ung solar explosion ng araw.. baka daw umabot d2 iyon at masira ung mga satelite natin..
Tsaka what about ung Barnard's star? Ung star na gumagalaw papunta sa direction natin?
^ never heard about Barnard's star
Yes our sun will probably become a red giant and swallow up the earth, but that's several billion years from now. By then humans should have migrated to other parts of the universe, that is assuming humans survive long enough without being wiped out by natural or self-induced cataclysmic events.

^^ Mt. Olympus vs. Mt. Everest vs Mauna Kea
Rising above the Red Planets frequent dust storms is the Olympus Mons -the tallest known volcano and mountain in our solar system. The central edifice of this shield volcano stands 27 kilometers ( 88,580 ft) high above the surface -or three times the elevation of Mount Everest above sea level and 2.6 times the height of Mauna Kea above its base. It is 550 km in width, flanked by steep cliffs, and has a caldera complex that is 85 km long, 60 km wide, and up to 3 km deep with six overlapping pit craters. Its outer edge is defined by an escarpment up to 6 km tall; unique among the shield volcanoes of the Red Planet.
Malapit na daw mag supernova ang Betelgeuse. They say within the next million years. Since it is hundreds of light years away, maybe the process has already begun.
Maybe not everyone knows this.
When you look at the night sky, you are looking at the stars as they were years ago, depending on how far they are. If a star is 1 million light years away, then you are looking at its appearance when it was 1 million years ago, because it takes its light that number of years to travel to earth.
In short, we are looking at very, very old snapshots of the stars, some of them may not exist anymore!
true.. time and space.
have u ever wonder if our asteroid belt is actually just shattered pieces of an old planet?

i think these are just refractions of light because of the atmosphere fin. but i heard that fog and a dominant color of light in our atmosphere also affect how we see our moon.

It was a red giant to begin with which is a later part of a star's life cycle. What's cool is, we will never see it in our lifetime dying, or even my great great grandchildren's.

there's a theory on that fin pero it's unsupported. i'd like to think it was a planet too!
moon... saan ba to galing?
1. The Fission Theory: The Moon was once part of the Earth and somehow separated from the Earth early in the history of the Solar System. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.
2. The Capture Theory: The Moon was formed somewhere else, and was later captured by the gravitational field of the Earth.
3. The Condensation Theory: The Moon and the Earth condensed together from the original nebula that formed the Solar System.
4. The Colliding Planetesimals Theory: The interaction of earth-orbiting and Sun-orbiting planetesimals (very large chunks of rocks like asteroids) early in the history of the Solar System led to their breakup. The Moon condensed from this debris.
5. The Ejected Ring Theory: A planetesimal the size of Mars struck the earth, ejecting large volumes of matter. A disk of orbiting material was formed, and this matter eventually condensed to form the Moon in orbit around the Earth.

kung papipiliin kayo ng thery dyan, ano pipiliin nyo?
I'm aware of the Theory 1,4, and 5.. Yeah.. laking butas nga nung sa Pacific Ocean..
pero kung totoo yung theory number 1, ang bizarre nun!
imagine, how did it happened? a chunk of the earth to rise up to the heavens and became the moon. ang weird XD
^^ napingas iyon ng isang malaking planeta na nakaumpog sa earth siguro dahil sa nawala xa sa orbit or something.
#3 ! :D para lang silang siblings ni earth ;D
medyo OT:
naalala ko yung isang dialogue sa family guy..
brian's stupid girlfriend: get this! Ever wonder why you never see the sun and the moon at the same time?
peter: oh my god! they're the same person
brian's stupid girlfriend: I know! right?
(paraphrasing)

An obligatory post, which I've also posted in "Interesting Reads on Philosophy" -
The Pale Blue Dot
(https://www.pinoyguyguide.com/forums/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FMH4u7.jpg&hash=ca1f2e4a9831bda814943074ad96f4087adaba4c)
Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.

^will try to catch it doc if i manage to wake up early.
Cosmologists say we are lucky to live in this era. If we were born later, we would not be able to observe and appreciate the celestial bodies, as they are rapidly accelerating away from us due to the expansion of the universe.

PAGASA: 2011's finest planetary alignments to occur in May
Five planets will align at least three more times this month in what state astronomers considered as the "finest planetary conjunctions" of this year.
The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said the planets will line up in the eastern horizon at 5 a.m. on May 9, 13, and 30.
"Mars, Jupiter, Mercury, Venus, Uranus and Neptune will be found lining-up above the eastern horizon ... (For) Uranus and Neptune (stargazers) will be needing a star map and a binocular or a modest-sized telescope for its proper viewing," PAGASA acting administrator Nathaniel Servando said in PAGASA's astronomical diary for May.
"Saturn will be visible in the evening sky throughout the month. The Ringed planet will be located among the background stars of the constellation Virgo," he added.
Also, he said the planets will lie among the background stars of the constellation Pisces, except for Neptune, which will be found at the constellation of Aquarius.
He said the first line-up already occurred last May 1.
Big Dipper
Servando also said that after sunset, the grouping of stars known as Big Dipper is well placed high in the northeastern sky.
"The North Star Polaris can easily be located under normal weather condition by using the reference or the pointing stars namely Dubhe and Merak. By using their distance, an imaginary line can be drawn downward passing to these two stars and counting five times," he said.
Polaris is the end point star of the handle of the Small Dipper while the curved handle of the Big Dipper is pointing towards a bright orange star Arcturus of the constellation Bootes. — LBG, GMA News

The Pale Red Dot: Most Distant Galaxy Ever Discovered
"Astronomers have used Hubble to spot what they think is the furthest and one of the very earliest galaxies ever seen in the Universe. Candidate galaxy UDFj-39546284 appears as a faint red blob in this ultra deep field exposure taken with the NASA/ESA Hubble Space Telescope. This is the deepest infrared image taken of the Universe. Based on the object's colour, astronomers believe that its light has taken 13.2 billion years to reach us. The current known age of the Universe is 13.7 billion years."

May bagong planet daw sa Gliese_581 constellation confirmed to have liquid in water form! :o
http://en.wikipedia.org/wiki/Gliese_581_d (ewan ko kung updated ba ang wiki nito, nabasa ko lang din sa newspaper eh)
And I found both of their projects cool: A Message From Earth (http://en.wikipedia.org/wiki/A_Message_From_Earth) and Hello From Earth (http://en.wikipedia.org/wiki/Hello_From_Earth). Para lang kahawig ng colonization era noon, only in space. Sent to the solar system (Gliese_581).
http://gizmodo.com/5802902/new-home-for-humans
Cosmos magazine reports that French researchers think they've found the first planet other than Earth capable of sustaining life, concluding that it probably has a dense carbon dioxide atmosphere and that "the climate of Gliese 581d is not only stable against collapse but warm enough to have oceans, clouds and rainfall." Yes! I just set some coal on fire to watch that shit burn.
It orbits the star Gliese 581 in the so-called Goldilocks zone (not too hot; not too cold), which means that water is likely to exist there in liquid form. Gliese 581d is about twice the size of Earth, if seven times its mass. It's a neighbor of Gliese 581g, or Zarmina's World, but unlike that planet, it is certain that this one exists. Sweet!

NASA to Abandon Mars Spirit Rover (http://www.nytimes.com/2011/05/25/science/space/25rover.html)
"NASA said on Tuesday that it was abandoning efforts to get back in touch with Spirit, one of the two rovers on Mars. Spirit, which has been stuck in a sand trap for two years, fell silent last year as winter arrived and its solar panels could no longer generate enough electricity. Engineers had hoped that the rover would revive when spring returned, but they never heard from it again."

Asteroid To Buzz Earth Monday, June 27th
Asteroid 2011 MD, a chunk of rock estimated to be 25 to 55 feet (8 to 18 m) across, is expected to pass less than 8,000 miles above Earth's surface around 1 p.m. EDT (17:00 UT) on Monday, June 27th. The actual event will be observable only from South Africa and parts of Antarctica, but the approach will be visible across Australia, New Zealand, southern and eastern Asia, and the western Pacific.
http://www.skyandtelescope.com/observing/highlights/124430479.html
8000 miles is approximately the diameter of the Earth
