The dust cloud, called X7 and about as massive as 50 Earths, is orbiting our galaxy's supermassive black hole Sagittarius A*. Over the past 20 years, astronomers have observed the cloud's journey ...

A new study suggests that the object, called X7, could be a cloud of dust and gas that was created when two stars collided. The researchers believe it will eventually be drawn toward the black ...

Following two decades of monitoring a dusty gas filament (known as X7) from W. M. Keck Observatory, astronomers believe the cloud will eventually get pulled toward Sagittarius A* (Sgr A*) and ...

In more recent observations, the strange object — dubbed X7 and believed to be a cloud of dust and gas about 50 times the mass of Earth — has become immensely elongated by the powerful forces ...

Returning to our intriguing cloud of dust and gas, this object is named X7, has a mass equivalent to about 50 Earths and appears to have been swirling around Sgr A* for decades at ungodly speeds ...

The dust mass, which forms in the Sahara Desert in northern Africa and blows thousands of miles across the Atlantic Ocean, is ...

SAN JUAN, Puerto Rico — A massive cloud of dust from the Sahara Desert blanketed most of the Caribbean on Monday in the biggest event of its kind this year as it heads toward the United States.

Scientists now believe that it could be a cloud of gas and dust that was thrown out when two stars collided. In the time since, the object known as X7 has been stretched out, and is gradually ...

“This is a very messy process: The stars circle each other, get closer, merge, and the new star is hidden within a cloud of dust and gas,” she said. “X7 could be the dust and gas ejected fro ...

Now, having examined the evolution of X7 using 20 years of data gathered by the Galactic Center Orbit Inintiative, astronomers from the UCLA Galactic Center Group and the Keck Observatory propose that ...
