Supermassive black holes

The first-ever photo of a black hole, taken using a global network of telescopes conducted by the Event Horizon Telescope (EHT) project, to gain insight into celestial objects with gravitational fields so strong no matter or light can escape, is shown in this handout photo released April 10, 2019.

The collision of two black holes - a tremendously powerful event detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO - is seen in this still image from a computer simulation released in Washington February 11, 2016. Scientists have for the first time detected gravitational waves, ripples in space and time hypothesized by Albert Einstein a century ago, in a landmark discovery announced on Thursday that opens a new window for studying the cosmos.

Giant plumes of radiation seen in X-rays from Chandra (purple) and radio data from the Very Large Array (orange) from radio galaxy 3C353, a wide, double-lobed active galaxy that is very luminous at radio wavelengths, where the galaxy is the tiny point in the center in this image released on November 1, 2013. Jets generated by supermassive black holes at the centers of galaxies can transport huge amounts of energy across great distances.

A ring of stars circling Sagittarius A*, the Milky Way's central black hole, shows a combination of infrared and X-ray observations indicating that a surplus of massive stars has formed from a large disk of gas around the black hole. Dozens of massive stars, destined for a short but brilliant life, were born less than a light-year away from the Milky Way's central black hole, one of the most hostile environments in our galaxy, astronomers reported October 13, 2005.

A composite image shows the jet from a black hole at the center of a galaxy striking the edge of another galaxy, the first time such an interaction has been found. In the image, data from several wavelengths have been combined. X-rays from Chandra (colored purple), optical and ultraviolet (UV) data from Hubble (red and orange), and radio emission from the Very Large Array (VLA) and MERLIN (blue) show how the jet from the main galaxy on the lower left is striking its companion galaxy to the upper right. The jet impacts the companion galaxy at its edge and is then disrupted and deflected, much like how a stream of water from a hose will splay out after hitting a wall at an angle.

A composite image of a galaxy illustrating how the intense gravity of a supermassive black hole can be tapped to generate immense power released by NASA May 15, 2013. The image contains X-ray data from NASA's Chandra X-ray Observatory (blue), optical light obtained with the Hubble Space Telescope (gold) and radio waves from the NSF s Very Large Array (pink). This multi-wavelength view shows 4C+29.30, a galaxy located some 850 million light years from Earth. The estimated mass of the black hole is about 100 million times the mass of our Sun.

The galaxy cluster PKS 0745-19 is shown in this NASA composite image containing X-rays from Chandra (purple) and optical date from the Hubble Telescope (yellow) released December 19, 2012. The black hole at the center of this galaxy is part of a 2012 survey of 18 of the biggest known black holes in the universe. Researchers found that the black holes in the survey may be about ten times more massive than previously thought.

The supermassive black hole at the center of the Galaxy is located inside the bright white patch in the center of the image. A panoramic X-ray image of the Milky Way galaxy reveals a turbulent heart teeming with 1,000 sources of high energy that might be dying stars or black holes, astronomers reported.

Hong Kong in turmoil

Ten weeks of confrontations between police and protesters have plunged Hong Kong into turmoil, and presented the biggest popular challenge to Chinese President Xi Jinping since he came to power in 2012. Demonstrators say they are fighting the erosion of the "one country, two systems" arrangement that has enshrined some autonomy for Hong Kong since China took it back from Britain in 1997.
