Dilithium, Li 2, is a strongly electrophilic, diatomic molecule comprising two lithium atoms covalently bonded together. Li 2 has been observed in the gas phase.It has a bond order of 1, an internuclear separation of 267.3 pm and a bond energy of 102 kJ/mol or 1.06 eV in each bond. [1]
The smaller black hole orbits the larger one, which remains stationary in the animation and is surrounded by a disk of gas. When the smaller black hole crashes through the disk, it produces a flare brighter than 1 trillion stars. But the smaller black hole's orbit is elongated and moving relative to the disk, causing the flares to occur ...
In this image of M87* taken on 11 April 2017 (a representative example of the images collected in a global 2017 EHT campaign), the shadow of a black hole is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape.
At the center of the Milky Way galaxy resides a supermassive black hole four million times the mass of our sun called Sagittarius A* that some scientists have called a gentle giant because of its ...
NASA researchers combined years of data and new imaging techniques to learn more about a "tipped over" black hole that is moving in an unexpected way. The black hole is located in a galaxy called ...

A black hole's event horizon is the point of no return beyond which anything - stars, planets, gas, dust and all forms of electromagnetic radiation - gets swallowed into oblivion. Scientists ...
The LIGO Scientific Collaboration announces the first detection of a black hole merger via gravitational wave observations on February 11, 2016. The Event Horizon Telescope observes the supermassive black hole in Messier 87's galactic center in 2017, leading to the first direct image of a black hole being published on April 10, 2019.
