Scientists Suggest They May Have Captured The Very First Image Of A Black Hole Within The Milky Way
Scientists working with the Event Horizon Telescope project may have have captured an image of a black hole in the Milky Way, which could be ‘the most iconic ever’.
Scientists have suggested that for the first time, they may have finally captured what could end up being the first image of a black hole within the Milky Way. A team of international astronomers have been hard at work analyzing two specific areas of space located in Sagittarius A and M87 through the Event Horizon Telescope project (EHT), and have reported that they have discovered what amounts to “spectacular” data during their research, which in this case, would be the faint image of the silhouette of a black hole.
According to the Daily Mail, this image may very well prove to be “one of the most iconic ever.” The scientists involved with the EHT collaboration are currently analyzing tremendous amounts of data from 2017, and this data is set to be made public later on this year.
Hungry Black Hole Shines Light on Astronomical Phenomenon
Astronomers have been watching a very hungry black hole devour the gases of a nearby star for almost a year.
A specialized instrument aboard the International Space Station in March detected an enormous explosion of X-ray light nearly 10,000 light years from Earth.
The source: a black hole called MAXI J1820+070, caught in an outburst, spewing surges of X-ray energy as it devours inhales celestial dust and gas.
Japan’s pioneering detector set to join hunt for gravitational waves
The ¥16.4-billion (US$148-million) observatory — Japan’s Kamioka Gravitational Wave Detector (KAGRA) — will work on the same principle as the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States and the Virgo solo machine in Italy. In the past few years, these machines have begun to detect gravitational waves — long-sought ripples in the fabric of space-time created by cataclysmic cosmic events such as the merging of two black holes or the collision of two neutron stars.
LIGO’s Asian cousin will this year deploy ambitious technology to improve sensitivity in the search for these faint, cosmic ripples — but its biggest enemy could be snowmelt.
NASA telescope spots black hole shrinking after devouring a star
About 10,000 light years away from Earth, a black hole is engaged in a stellar feast, devouring the gases of a nearby star.
A stellar meal provides tantalizing new evidence about black hole evolution.

Dark matter can be heated and moved say scientists
Scientists have been researching dark matter for years in an attempt to better understand the universe. Researchers have now found evidence that dark matter can be heated up and moved around as a result of star formation in galaxies. These findings are the first observational evidence for the effect called “dark matter heating.”
