'The galaxies that host these relativistic jets give out large amounts of radiation at radio wavelengths,' explains Marco. The team inspected five categories of galaxies for visible signs of recent or ongoing mergers - two types of galaxies with jets, two types of galaxies that had luminous cores but no jets, and a set of regular inactive galaxies. It is these jets that Marco Chiaberge from the Space Telescope Science Institute, USA (also affiliated with Johns Hopkins University, USA and INAF-IRA, Italy) and his team hoped to confirm were the result of galactic mergers. The hot material within the jets is also the origin of radio waves. The two high-speed jets of plasma move almost with the speed of light and stream out in opposite directions at right angles to the disc of matter surrounding the black hole, extending thousands of light-years into space. Whilst most galaxies are thought to host a supermassive black hole, only a small percentage of them are this luminous and fewer still go one step further and form what are known as relativistic jets. The team studied a large selection of galaxies with extremely luminous centres - known as active galactic nuclei (AGNs) - thought to be the result of large quantities of heated matter circling around and being consumed by a supermassive black hole. The results lend significant weight to the case for jets being the result of merging black holes and will be presented in the Astrophysical Journal.ДЄ team of astronomers using the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3) have conducted a large survey to investigate the relationship between galaxies that have undergone mergers and the activity of the supermassive black holes at their cores. Silence saves you from looking like a fool - because if your silence is not enough for people to realize that something is wrong - will your words even matter? Rania Naim is a poet and author of the new book All The Words I Should Have Said, available here.In the most extensive survey of its kind ever conducted, a team of scientists have found an unambiguous link between the presence of supermassive black holes that power high-speed, radio-signal-emitting jets and the merger history of their host galaxies.ДЄlmost all of the galaxies hosting these jets were found to be merging with another galaxy, or to have done so recently. Sometimes itвЂ™s better than crying, better than yelling and better than screaming. Sometimes thereвЂ™s really nothing you can say or do. Silence is the worst, but sometimes it says it all. ItвЂ™s the only way to quiet the noise in your head. Sometimes silence is the only way to figure out whatвЂ™s going on inside you. When youвЂ™re going through something no one understands, when your heart is breaking over a relationship you were never in, when you want to give up but you have a life waiting for you to make things happen, when nothing makes you feel good but you have to be grateful for it all.

You donвЂ™t want to talk about them because you want to protect them from what people might say, you donвЂ™t want anyone to tell you that you should forget about it or itвЂ™s not worth your time. You say nothing when someone mentions their name, you say nothing when someone talks about their love life. So you watch them in silence, you miss them in silence, you think about them silently and you pretend like you donвЂ™t want them. Loving someone so much but you canвЂ™t say anything because you donвЂ™t want to lose them, you donвЂ™t want to push them away, you donвЂ™t want things to be awkward if they donвЂ™t feel the same way. Sometimes silence is better than knowing that there is no chance. Silence is tough but sometimes the truth is tougher.

Sometimes silence is the only answer to someone who is unaware of the pain they caused you, itвЂ™s the only answer to someone who doesnвЂ™t care to know if youвЂ™re okay. Not knowing what to say, not knowing if it will make a difference, not knowing if it will make matters worse. Silence is ignorance and sometimes ignorance is bliss. Silence sometimes saves you from further rejection or hearing things you donвЂ™t want to hear. Silence is better than sounding crazy, weak or irrational. ItвЂ™s painful to talk about what hurts, itвЂ™s painful to tell someone that they broke your heart and itвЂ™s painful to show someone how vulnerable you are and how much they mean to you when youвЂ™re not sure what kind of reaction youвЂ™ll get and when youвЂ™re not sure what you really mean to them.
