Five years ago scientists proposed the hypothetical existence of a large world tens of millions of miles from the Sun, which has come to be known as "Planet Nine."
Scientists spotted the X-ray flash using NASA's NuSTAR satellite.
Scientists are now trying to work out what caused the mystery burst .
Japanese researchers propose new plan to hunt down our galaxy's "isolated black holes."
Without female STEM role models, we risk acquiescing to a world where even brilliant minds like Bouman are dragged into discriminatory devolutions.
His general theory of relativity has passed two serious tests from the universe's most extreme conditions in the last few years.
Bouman, a computer scientist with the Event Horizon Telescope project, talks about seeing the first-ever image of a black hole.
"Space Hobbits are our new frontier."
In 2017 scientists created an Earth-sized virtual telescope and used it to take a "picture" of a black hole.
On June 16, 201, the discovery of a strange flare in the sky was reported in an astronomical telegram.
The observations offer "a resounding confirmation" of the supermassive black hole long-believed to be lurking at the heart of our galaxy.
If correct, the new theory would mean these black holes would all have about the same mass.
"The reality is that global economic growth is closely linked to trade, and raising tariffs will inevitably reduce the volume of trade and drive down business confidence," the article argued.
The incredible discovery will help astronomers unlock the secrets of the universe's very first galaxies.
This is the first time astronomers have directly imaged the brutal phenomenon.
The broadcast will "create a link" between Hawking's presence on Earth, his desire to visit space and his scientific explorations of the universe, his daughter said.
Last year's collision was the first in which scientists could actually see what was happening during and after the collision.
Black holes are voracious eaters, but they don't have the nicest table manners.
Light from the jets can outshine entire galaxies.
The planets face supernovas, gamma-ray bursts and gravity-disrupting stars in the crowded center of the Milky Way.
Infrared images can help scientists peek behind the veil of enormous dusty clouds.
