We want to share our excitement about the first-ever direct detection of gravitational waves! The event happened right before the beginning of the first observing run of the advanced LIGO detectors, on 14 September 2015. The waves were generated as two black holes merged into a single black hole about 1.3 billion light years from Earth. In astronomy units this is 410 Mpc, approximately 10% of the way across the visible Universe!
Just as exciting: this is also the first-ever observation of binary black holes. In fact, since black holes are black, and emit no light or electromagnetic radiation, this is the only way we can see them.
Did Einstein@Home play any role in this? No, it didn’t. The signal in the instrument lasted only about 1/4 of a second. It’s not a continuous-wave signal like the type that Einstein@Home has been searching for. But since the observing run ended in mid January, we have been preparing the data to start a new low-frequency all-sky search for continuous gravitational waves. We are now starting to run this on Einstein@Home, so please sign up your computers and disable their sleep mode! In the next months we will extend the frequency range of the continuous waves all-sky searches, target interesting point sources and we are also gearing up to perform broader surveys for binary black hole mergers.

When will our hosts start receiving work units with derived from the measurements made that (now) include the low-frequency readings?
I’ve just looked up in the sky above my house toward where the wave came from. What has seemed some pretty neat concepts for so long are now so real. Awesome ! The amazing ambition has been fulfilled and this means so much more besides, including the future here at our project. Congratulations to all of the scientists around the world that have strived so long for this result, many of whom were young women & men when this enterprise began.
Now E@H will really rock n’ roll with the rhythms of the universe ! ~~~~~~~~~~ 🙂 😉
Cheers, Mike.

Just finished to watch press-conference of MSU part of team.
Marvelous results!
Congratulations to all involved!

Congratulations to everyone involved! I’m looking forward to confirmation of the results by future measurements and to a whole new way of doing astronomy 🙂
Fun fact: The signal was detected on my birthday ^^
Congratulations to everyone involved! Congrats also to all volunteers as a little part of the project.
Прочитал статьи в СМИ нигде нет упоминания Einstein@home почему так?

Congratulations! Feels exciteda and pround to be part of it

Открытие все же не этим проектом сделано непосредственно. Тут другие временнЫе характеристики сигналов совсем смотрят. Хоть и с того же прибора.

And for us just waking up……
Update on LIGO and the search for gravitational waves video
It just a new era in the search is beginning! Keep on crunching!
OMG!!! YESS, the best new in Radio-astronomy in this century…The general relavity theory has been confirmed!!!
This discovery provides us to know better where we are and what,how,who and why happend ,I´m sure.
This is for you Albert Einstein!!
Huges greetings from Spain!

My computer is signed up, but gives Einstein very low priority. Why? Because your units are very large and have very short times to deadline. Too greedy, not allowing other projects to run. I have commented on this before, but my comments were, naturally, ignored. This state of affairs will continue, allowing Einstein to get new work only when other projects have no tasks available. I am not alone in this observation; you should take note.

Einstein is one of the lightest resource usage projects I know, both for my GPUs and my CPU. I hope they make it more difficult to better utilize my i7-4771.

Hello Bob. The nature of the work units themselves are dictated by science requirements ie. in order that results returned will have genuine physical meaning and that our search strategy for the entire set of hosts can proceed efficiently. They cannot take account of an individual’s choice of project mix on a given host. In fact you have answered this question for yourself before :
My PC is capable, my philosophy is the limiting factor!
Cheers, Mike.

Amazing engineering and science.
It’s the first of many new starry messages like Sidereus Nuncius was
This is one of the most important astronomy discoveries ever! Looking forward to participating in continuous gravitational wave searches here. Expecting many more discoveries to come!
The PR on the BBC in Britain was good but sadly there was no mention of Boinc or the great contribution made by so many people who have freely given valuable computing cycles. This in my mind is a missed opertunity to recrute new people who would contribute.
I have created a new team challenge in boincStats that starts this sunday to sunday next week, to celebrate this huge new…
