Sending a satellite into a black hole
“ESA and ASI put the satellite into its orbit with a precision of just 400 metres.” This precise positioning will help improve the quality of the researchers’ measurements, Ciufolini adds. The rocket’s performance was “spectacular”, says mission leader Ignazio Ciufolini, a physicist at the University of Salento in Lecce, Italy. It was built by the Italian Space Agency (ASI) at a cost of around €10 million (US$10.2 million), and lifted off on the maiden flight of an upgraded version of the European Vega rocket, called Vega C. The Laser Relativity Satellite 2 (LARES-2) launched from the European Space Agency (ESA) spaceport in Kourou, French Guiana, on 13 July. BaudonĪ newly launched satellite aims to measure how Earth’s rotation drags the fabric of space-time around itself - an effect of Einstein’s general theory of relativity - ten times more accurately than ever before.

The new study, which also incorporates data from the Sloan Digital Sky Survey and NASA's Chandra X-ray Observatory, will be published next week in the journal Astronomy & Astrophysics. "If our theory is correct, the observations provide strong evidence that supermassive black holes can actually merge," Bianchi said in the same statement. "There is already evidence of black hole collisions for stellar-mass black holes, but the process regulating supermassive black holes is more complex and not yet completely understood." When the two central black holes finally merged, this emission stopped, and the newly created leviathan rocketed off in the opposite direction.

This gravitational-wave emission occurred preferentially in one direction, the idea goes. As this happened, the black holes emitted gravitational waves-the ripples in space-time first proposed by Albert Einstein a century ago, and first detected directly last year by the Laser Interferometer Gravitational-Wave Observatory (LIGO) project. The two galaxies' central black holes circled closer and closer to each other during the collision. Based on this observation and theoretical work, the study team thinks everything started with the collision of two galaxies 1 to 2 billion years ago. Why did this strange object go rogue? Hubble data also revealed that 3C186 has arc-like features called tidal tails, which are generated by gravitational forces during galaxy mergers. Indeed, it's farther away from the center than any such black hole ever observed, researchers said. But 3C186's quasar is not at its galaxy's core. That's not surprising most if not all galaxies harbor supermassive black holes at their cores. Hubble images revealed a quasar-the incredibly bright energetic signature of a supermassive black hole-within the galaxy. The study team used NASA's Hubble Space Telescope to study the galaxy 3C186, which lies about 8 billion light-years from Earth.

“We estimate that it took the equivalent energy of 100 million supernovae exploding simultaneously to jettison the black hole,” study co-author Stefano Bianchi, from Roma Tre University in Italy, said in a statement. And the behemoth is currently traveling outward at 4.7 million mph (7.6 million km/h)-fast enough for the black hole to escape its galaxy completely in 20 million years, researchers said. The monster black hole has already zoomed 35,000 light-years away from its galaxy's center, farther than Earth and its sun are from the core of our own Milky Way. A supermassive black hole heftier than 1 billion suns has been ejected from the core of its galaxy by gravitational waves, a new study suggests.
