An international team
of astronomers, led by researchers at Japan’s Tohoku University, has just
reported finding the faintest satellite galaxy ever seen orbiting our home
galaxy, the Milky Way. All stars are
born in great islands or groupings of stars called galaxies.
Big galaxies like the
Milky Way are surrounded by smaller “baby galaxies” (or satellite galaxies),
some of which collide with it over cosmic times. About 50 such galaxies are currently known to
orbit our Milky Way – with the two “Magellanic Clouds” (discovered by Ferdinand
Magellan’s crew) being the most famous of them.
Because many of the
smallest galaxies are very faint, they are hard for us to make out. Remember, we are inside the Milky Way, and so
(as we try to look outwards) we always have to observe through the stars and
star clusters of our own galaxy. The
faint baby galaxies can be hard to tell apart from clusters or groups of stars
in the Milky Way itself. (This is why it’s hard to get a good photo of the
Milky Way; we are inside it and so it’s
like trying to take a selfie from inside your kidney. The view is not so clear.)
Still, using the giant
Subaru telescope (whose mirror is more than 24 feet wide), the team was able to
find the faintest baby galaxy ever found, which is being called Virgo I (since
we see it in the constellation of Virgo.)
At an estimated distance of 280,000 lightyears from us, Virgo I was much
fainter than earlier surveys for our neighbor galaxies were able to reveal.
The whole Virgo I “dwarf
galaxy” is only about 248 lightyears wide.
Compare that to the 100,000 lightyear diameter of the Milky Way! The
Magellanic Clouds are estimated to be 7,000 and 14,000 light across. So you can see that Virgo I really is just a
baby. See the tiny smudge it makes on our accompanying image.
But if one such baby
galaxy has escaped our notice until now, chances are many others like it may
also be out there. Some of our theories
predict that major galaxies like the Milky Way should be surrounded by many
more dwarf galaxies that we have seen so far.
Virgo I leads astronomers to think that more may be out there -- just
waiting for bigger telescopes and more observations before they are discovered.
I just lost my man about three months ago though he is back again full of love and passion with the help of great man Dr. IKHIDE. I NORAH PEDRO from Norway, have been into a relationship with daniel mark since I was 22 years old and I am 28 now. I so much love him but I could not show the love, it was very difficult for me to prove my realness to him because I thought to prove my love to him might make him look down on me and go after other girls. for over six years Daniel has given me all that I ask of him. I always threatened him with break up each time I want to see his level of love for me because I was told if I threaten him, he will propose to me and then will get married to him before I can show my love despite his complains of him not sure of my love I was responding to him with negative words. though I was suspecting he has another girl in his life, I did not border to ask him about that because I was so sure of his love despite my attitude. on the 8th of September a day to my birthday he came and gave me so many lovely gifts like never before claiming to wish me a happy birthday in advance with his words and behavior I expected him to propose to me on my birthday night then I will also tell him of my pregnant for him. I wait for him on my birthday he did not show up not even a call, I tried his number and it was not going through I refuse to go check on him because the anger in me six days later I went to his house and I found nothing not even a sign of my Daniel once live there. I was disappointed, frustrated, confused with so many thoughts on my mind like hanging my self if I did not see him again because I can not my parent about the pregnancy when the man responsible for it had disappeared. our religion's against that, my family will be disappointed in me, I have brought them shame. I look for daniel everywhere till I could chat with him on social network, he warned me never to disturb him again because he already had found another girl that he wants to live his life with, after a while, he blocked me from all access then I could not tell him of my pregnancy for him. so, I needed help from all corners of life, I decide to check to google my self or read some write up on-site on how to coup with my pain because I could not tell anybody about it not even my friends were aware of my pregnancy. I keep reading to cancel my self till I find how Dr. IKHIDE helps so many persons from different walks of life with their testimonies. then I decide to also contact him with dr.ikhide@gmail.com. Because I do not know much about contacting a spell caster, I was not sure he can bring my Dan back but I decide to give him a try though his requirement was another problem I meet with a friend for help because I could not the items that he needed I have to plead with Dr. IKHIDE to help me get the items because really need my man back to take away my shame. just two days after I send him the requirement Daniel calls me, plead for forgiveness. just yesterday he propose to me and I am so happy. you can also contact him with dr.ikhide@gmail.com
