Scientists have long wondered whether matter is falling into the massive black hole in the center of our Milky Way galaxy, or being ejected from it. Now, scientists are searching for an answer.
Where can you find the most methane emissions in the United States? Scientists may have found that out with the use of a new map. They've mapped satellite data in order to uncover the nation's largest methane signal seen from space.
Mars is going to get a spectacular show in the form of a comet. On Oct. 19, Comet Siding Spring will come within about 87,000 miles of Mars, which is about one-third of the distance of the moon from Earth.
Here on Earth, people are gearing up for Halloween by carving pumpkins into jack-o-lanterns and preparing their costumes. Now, it looks like the sun has also decided to show off just in time for the scariest night of the year.
Scientists have learned a bit more about how the universe evolved by studying leaky galaxies. They've taken a closer look at large star-forming galaxies to measure radiation leaks to see how the first stars were formed.
NASA's Hubble Space Telescope has helped a team of scientists to make the most detailed global map yet of the glow of a turbulent planet outside our solar system.
It turns out that there may not be nearly as much dark matter in the Milky Way as scientists thought. New measurements have shown that there is about half as much as this mysterious substance in the galaxy as previously estimated.
Astronomers have now seen right to the heart of an exploding star, thanks to a combination of data from telescopes. The findings reveal a highly-detailed look at exactly what happens when a star in a binary system hurls material into space.
Scientists have stumbled on a pulsating dead star shining with the energy of about 10 million stars. Called a pulsar, this dead star was previously thought to be a black hole because it was so powerful.
A certain black hole is more insatiable than expected. Astronomers have discovered a black hole that is consuming gas from a nearby star about 10 times faster than previously thought possible.
Scientists have discovered a snaking, extended filament of solar material that currently lies on the front of the sun and extends about one million miles across from end to end.
While researchers once believed that there must have been a small amount of oxygen in the Earth's atmosphere before life began, they weren't sure where this non-life oxygen came from. Now, they may have some answers..
