Ghostly Ring of Dark Matter! will Milky Way have one?

A distant galaxy cluster has yielded tantalising evidence of dark matter in the form of a gigantic ring that surrounds the clusters.

Although dark matter canot be see directly with our naked eyes, its present can be detect because its gravity bends and magnifies the light coming from more distant objects - a phenomenon known as gravitational lensing. By measuring the amount by which the more distant lights has been "lensed" and distorted, the team os astronomers using the Hubble Space Telescope were able to infer how much dark matter were present. they found it was in a ring around the cluster ZwC10024+1652, five billion light years away.

Curious about the ring?
Well, the curious ring shape can be explained by the collision between this cluster and another smaller cluster which happened about 2 billion years ago. This is the second example of dark matter being found around galaxy clusters. The first instance was the Bullet Cluster, found in October 2006.

Our Milky Way galaxy also in future, as predicted by astronomers will collide with Andromeda, which located about 2 billion light years from us today. The Andromeda is move toward us, with average speed of 500,000 km/s. And, if its really happend, it will be the end of both galaxy, and soon, a new galaxy will slowly born from the collision.

The Sun Approaching Solar Maximum

Helium gas caught in the sun's atmosphere may be responsible for the enormous solar explosions known as Coronal Mass Ejections (CMEs). Scientist from the Loas Alamos National Lab, used NASA's Wind spacecraft to make over 2.5 million measurements of the Sun over a decade of observation. It is believe that heliumgas builds up in the solar atmosphere, the corona. yet the solar wind, a constant stream of charged particles emanating from the sun isn't strong enough to completely eject the helium into space so it gradually accumulates until it is violently thrown off in a spectacular CME.

The discovery of oscillations in the Sun provides a way to study the Sun's insides.

CMEs are some of the most violent and powerfull explosions on the Sun and, although they are not well understood, they seem to greatly affect solar wind speeds. Observations of these explosions show that the amounts of helium present in their ejections are around 5-10 times the abundances seen in the normal solar wind that is expelled continuously from the Sun.

But, scientist don't yet understand a most basic aspect of the solar wind: how exactly does material in the solar corona accelarate to the solar wind speeds of between 960,000 and 1.6 million kilometres per hour???

Scientists are also uncovering more about the very centre of the Sun after 30 years searching for elusive oscillations deep within the Sun. Now, new observations with the Global Oscillation at Low Frequency (GOLF) instrument in the Solar and Heliospheric Observatory (SOHO) may ahve detected the "telltale" ripples created by collisions between dense gas and gaseous material falling deeper into the Sun. These ripples, known as "g-modes", can tell us a great deal about the solar interior and the Sun's core. Also imprinted on these oscillations is information about the conditions in which the Sun formed and the rotation of the ancient cloud of gas that spawned it.

Below are  series pix of the Sun's, from the Solar and Heliospheric Observatory (SOHO), Extreme Ultraviolet Imaging Telescope. Thanks to my great buddy, Ezza from space agency, for sharing this superb pics with me...

The Sun's activities are so active...and will be more active within this few years. It is belive that the Sun will reach it solar activity in the year 2012, causing a huge magnetic storm in a history of mankind.



The World Health Organization (WHO) has raised the swine flu pandemic alert level to PHASE 5 - just one step below the highest level. The decision comes as the number of countries with confirmed cases rises to at least 10, with 1 death in the United States of America. 

The increase to level 5 indicates that there is sustained human-to-human transmission in communities in different geographical locations.

Star Trek...The Star Trek is a science fiction television series created by Gene Roddenberry that aired from September 8, 1966 to September 2, 1969. Though the original series was titled simply Star Trek, it has acquired the retronym Star Trek: The Original Series (ST:TOS or TOS) to distinguish it from the spinoffs that followed, and from the Star Trek universe or franchise they comprise. Set in the 23rd century, the original Star Trek follows the adventures of the starship Enterprise and its crew, led by Captain James T. Kirk (William Shatner), his First Officer Mr. Spock (Leonard Nimoy), and his Chief Medical Officer Leonard McCoy (DeForest Kelley). William Shatner's voice-over introduction during each episode's opening credits stated the starship's purpose...
John Cho - Hikaru Sulu
Ben Cross - Sarek
Bruce Greenwood - Capt. Christopher Pike
Simon Pegg - Scotty
Chris Pine - James T. Kirk
Zachary Quinto - Spock
Winona Ryder - Amanda Grayson
Zoe Saldana - Nyota Uhura
Karl Urban - Dr. Leonard "Bones" McCoy
Anton Yelchin - Pavel Chekov
Eric Bana - Nero
Leonard Nimoy - Old Spock

I wanna watch the movie because, I'M A DIE HARD FAN OF STAR TREK....i do have all 7 season of Star Trek series and fell in love with Capt Jonathan Archer, Capt. Katherine Janeway and lotta others...hahaha. its a must die movie for me, as i've spent most of my free time wathing all the 7 seasons again and again.....

so guys...what are you waiting for



Do alert that the swine flu (H1N1) virus are suspected to arrived in our neighbour countries, Singapore , Thailand and Indonesia. 

The World health organization (WHO) raised the worlwide pandemic alert level to PHASE 4. A Phase 4 alert is characterized by confirmed person-to-person spread of a new influenza virus able to cause “community-level” outbreaks.” The increase in the pandemic alert phase indicates that the likelihood of a pandemic has increased.

What you can do to stay healthy??


  1. Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
  2. Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hands cleaners are also effective.
  3. Avoid touching your eyes, nose or mouth. Germs spread that way.

Avoid close contact with sick people. Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.  If you get sick, MOH recommends that you stay home from work or school and limit contact with others to keep from infecting them.


Eta Aquarids Meteor Shower on May 5 & 6

The Eta Aquarids are a light shower, usually producing about 10 meteors per hour at their peak. The shower's peak will occur on May 5 & 6, however viewing should be good on any morning from May 4 - 7. This year, a waxing gibbous moon will hide all but the brightest meteors. The radiant point for this shower will be in the constellation Aquarius. Best viewing is usually to the east after midnight.

The eta Aquarids are flakes of dust from Halley's Comet, which last visited Earth in 1986. Although the comet is now far away, beyond the orbit of Uranus, it left behind a stream of dust. Earth passes through the stream twice a year in May and October. In May we have the eta Aquarid meteor shower, in October the Orionids. Both are caused by Halley's Comet.

The eta Aquarids are named after a 4th-magnitude star in the constellation Aquarius. The star has nothing to do with the meteor shower except that, coincidentally, meteors appear to emerge from a point nearby. Eta Aquarii is 156 light years from Earth and 44 times more luminous than the Sun. Eta Aquarid meteoroids hit Earth's atmosphere traveling 66 km/s.

So, dont forget to look east before sunrise on May 5 & 6 (><)


Tsunami Ketika Gerhana Matahari 22 Julai 2009??

Terdapat khabar angin yang tersebar luas ketika ini, mengatakan akan berlakunya satu tsunami yang dahsyat pada 22 Julai 2009, pada hari berlakunya gerhana matahari kedua bagi tahun 2009 ini. Dikatakan akan berlakunya 3 gempa bumi bawah laut yang melangkaui bacaan 7 pada skala Richter di perairan luar pantai Taiwan, barat Jepun dan di gugusan kepulauan Pasifik Selatan, yang masing-masing berada dalam lingkungan laluan gerhana.

Ramalan mengatakan kejadian ini akan berlaku sekitar 3pm-7pm (tempoh gerhana) bakal mengakibatkan bencana yang besar di negara-negara sekitar termasuk Sabah & Sarawak di Malaysia.

Walaubagaimanapun, kesahihan berita ini wajar diragui kerana sehingga kini tiada kenyataan rasmi dibuat oleh agensi-agensi meteorologi & kaji bumi dari mana-mana negara, kecuali sedikit kenyataan dari seorang professor fizik, Universiti Tokyo yang meramalkan kejadian ini tanpa apa-apa asas atau kajian lanjut.

Apapun, bumi kita ini sudah semakin lanjut usianya. Dan, gempa bumi yang semakin kerap dan silih berganti berlaku di Timur telah lama di ceritakan sebagai salah satu daripada tanda-tanda kiamat. Sebagai manusia, kita kene sentiasa bersedia untuk menghadapi apa jua ujian Allah dalam apa jua situasi dan bentuk. 


Lyrids Meteor Shower on april 21 & 22

Date: April 21 & 22
Constellation: Lyra
Rate: 20 meteors per hour
Time: just after midnite
The Lyrids are an average shower, usually producing about 20 meteors per hour at their peak. These meteors can produce bright dust trails that last for several seconds. The shower will peak this year on April 21 & 22, although some meteors are usually visible from April 16 - 25. This year, a waning crescent moon will create only a slight distraction, but most of the meteors should be easy to see. Look for meteors radiating from the constellation of Lyra after midnight.
how to find constellation of Lyra?
u guys must look north of nite sky and spot Vega, the brightest star in that constellation.
