Mergers with other galaxies may have knocked the black hole in dwarf galaxies off-center, creating "wandering" black holes.
Researchers have observed the faint glow of "gas halos" around galaxies hosting supermassive black holes.
Intriguingly, the Neptune-like planet is is about four times bigger than the star itself.
The galaxy, spotted with ALMA, had been obscured by a huge cloud of dust, making it invisible to other telescopes.
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."
"In the search for life beyond our solar system, the most promising planets might not be Earth twins," says geochemist Stephanie Olson.
The snow contained substantial quantities of dust-enriched with iron-60—which isn't naturally produced on our planet.
The latest findings could help to explain some puzzling measurements collected by the Juno spacecraft, which is currently orbiting the planet.
The galaxies formed in the first two billion years after the Big Bang.
Our species has long grappled with the question of where consciousness originates. Is it an intrinsic part of the world around us?
These early stars may have blown up in a more violent and asymmetric fashion than previously thought.
Marvel's latest Avengers: Endgame posters have inspired a viral Avenge the Fallen meme that is taking over social media.
There may be way less dark matter out there than scientists think—and maybe even none at all.
The collision took place 10 billion years ago, when the universe was just three or four billion years old.
Fast radio bursts were recorded during a survey of the sky that began January 2017.
The search is on for an elusive particle that could shine a light on the "dark sector"—the vast majority of the universe that we cannot see.
Computer simulations will help scientists better understand the smallest and densest known stars.
Galaxy 12 billion light years away is spewing out stars 1,000 times faster than the Milky Way.
The Parker Solar Probe will zoom toward the sun at speeds of up to 430,000 miles per hour, making it the fastest spacecraft ever flown.
The finding shines new light on our understanding of the cosmos.
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.
