Messier 87 Galaxy

The massive galaxy M87 is the most spectacular example of an elliptical galaxy we can see from Earth. The most fascinating feature of this galaxy is its jet,which is visible in optical light as well as x-rays and radio emissions.

The jet extends from the central supermassive black hole of the galaxy and reaches out about 5,000 light-years. As a true elliptical galaxy, M87 has no obvious dust lanes and very little evidence of star formation. It likely formed from a recent merger between two other galaxies.

 FACTS ABOUT MESSIER 87

•   The interstellar medium in M87 is filled with gas that has been enriched somewhat by materials from stars that died long ago. There is dust in the galaxy, but far less than the Milky way contains.
• The black hole at M87's heart has the mass of about 3.5 billion Suns. It is surrounded by a diskmaterial that is slowly funneling into the black hole, heated by the action of a jet that is moving at very high speed out from the black hole.
• It is possible that the core of M87 has more than one supermassive black hole.
• The nuclear region of M87 is known as an "active galactic nucleus" due to its brightness in visible, x-ray, radio, and other wavelengths of light.
• M87 is surrounded by a corona of hot gas.
• Not far from M87 is a collection of galaxies arrayed in a pair of "chain-like" structures called "Markarian's chain". These are visible to amateur observers with good-sized telescopes.
• The first ever image captured of a black hole was of the one at the heart of M87:

Five Simple Tips to Increase the Life of Your Phone's Battery    Properly charging your smartphone is essential for maintaining the health of your battery, and ensuring better battery life and increased safety in the long run. Simply plugging your phone in as soon as you get home and leaving the charger on until you leave in the morning is not the right solution. Since there is a lot of different advice floating around on how to charge your phone, we decided to get you tips to get the most out of your smartphone's battery from the guys who built. Here's what they told us: 1. Don't let your phone overheat Heat is perhaps the worst enemy of lithium-ion batteries, the kind most smartphones use. "You should take basic precautions like not keeping your phone on the dash board of the car where it will get a lot of direct sunlight," You should also avoid charging your phone while playing graphically intensive games, because that will also raise the temperatur...

BLACK HOLE MYSTERY DATING BACK 40 YEARS SOLVED BY "BEST EVER" SIMULATION  A team of astrophysicists from Northwestern University, Oxford University, and the University of Amsterdam, used graphical processing units to crunch large sets of data and simulate how black holes interact with their accretion disks. The first photo of a black hole was captured in APRIL this YEAR PARIS: Scientists on Thursday unveiled the most detailed simulation of a black hole yet, solving a mystery dating back more than four decades over how the star-devouring monsters consume matter Coming fresh on the heels of the first ever photo of one of the giant objects, which are scattered across the Universe, astrophysicists are now several steps closer to understanding how they form and develop. A black hole is born when a large star collapses in on itself. Far from being a "hole", they are instead incredibly dense objects with a gravitational pull so strong that nothing, not even lig...

Small Parts / Electronic Components of Mobile Phone and Their  Function                               The PCB of a mobile cell phone has several small parts or electronic components. When LEARNING MOBILE REPAIRING , it is important to learn and understand how to identity these small parts or electronic components and understand their function. Identification of these small parts on the PCB OF MOBILE PHONE is easy if you know and understand some of the basic rules. It is also important to understand what to do if any of these small components is faulty. Most of these electronic components are SMD  ( SURFACE MOUNT DEVICES) They don’t have any leads like thru-hole ELECTRONIC COMPONENTS .                                                            ...
