Astronomers have uncovered new information about the swirling clouds of gas that form stars and galaxies. By studying brilliant quasars, the scientists have found that the clouds can shift and change much more quickly than previously thought.
How big is the universe? That's a good question, and scientists may have found out. They've measured the scale of the universe to an accuracy of one percent, a finding that could be key to determining the nature of dark energy.
Massive planets called "super-Earths" are common in our galaxy, the Milky Way. Now, though, scientists have found that these planets are far more likely to have an Earth-like climate than previously thought.
A celestial object may challenge traditional understandings about how planets and stars form. Astrophysicists have discovered an object that defies traditional categories of what is and is not a planet, showing that defining something isn't as easy as you might think.
The Sun is kicking off the new year with a bit of solar activity. It's unleashed the first X-class solar flare of 2014. Peaking at 1:32 p.m. EST on Jan. 7, the solar flare is significant and followed right on the heels of a mid-level flare earlier that day.
Astronomers have made a new discovery using NASA's Hubble Space Telescope and Spitzer Space Telescope. They've found and characterized four unusually bright galaxies as they appeared more than 13 billion years ago--just 500 million years after the Big Bang.
Could there be storms on stars? New research shows that there is. Using NASA's Spitzer Space Telescope, astronomers have uncovered swirling, stormy clouds on cool celestial orbs called brown dwarfs.
In the last nine years, one of the massive sunspot was seen this January and was captured by NASA's Solar Dynamics Observatory.
The first of a set of unprecedented, super-deep views of the universe from an ambitious collaborative program called The Frontier Fields was released at the 223rd meeting of the American Astronomical Society
An international team of astronomers has discovered the first Earth-mass planet that transits, or crosses in front of, its host star. KOI-314c is the lightest planet to have both its mass and physical size measured.
A Space Exploration Technologies' Falcon 9 rocket blasted off from Cape Canaveral Air Force Station in Florida on Monday to put a commercial communications spacecraft into orbit for Thai satellite operator Thaicom.
Using NASA's Fermi observatory, a team of astronomers have made the first-ever gamma-ray measurements of a gravitational lens. The findings open new avenues for future research, including a novel way to probe emission regions near supermassive black holes.
