After more than four years in space, restlessly searching for planets orbiting other stars, NASA's Kepler space telescope may have met its demise. The Kepler project is typically described in terms of raw numbers. As of the last official announcem...

In news that’s sure to delight young boys everywhere, scientists now have a better grasp on the impressive winds of Uranus. Neptune too. In a Nature study published today astronomers find that the most obvious weather patterns on the two ice giants...

The sun really seems to be ramping up its activity. At 9:45 EDT on Tuesday night, it unleashed its fourth flare in as many days. You can see it toward the left side of the sun in the image above from the Earth-orbiting Solar Dynamics Observatory sp...

Last night the sun unleashed its latest tirade: the third flare in as many days, and the most powerful one in 2013 so far. Exploding from the Sun's surface with energy equivalent to millions of 100-megaton hydrogen bombs, the flare spewed intense ...

Dark energy is the single most important element in the universe. It influenced how the cosmos was born, how it is evolving today, and how it all will end trillions of years in the future. Right now, this energy is causing the universe to expand fast...

What's up with that brown splotch sprawling across a broad swath of the South Pacific in the upper right corner of this satellite image? Nope, it's not some black hole that has just materialized in the middle of the ocean, threatening to suck New ...

Pollution is a growing concern here on Earth, but in a nearby star cluster pollution is actually proving pretty useful. Astronomers analyzing Hubble data have found that a pair of white dwarfs — the tiny, final form most of the universe’s stars wil...

If you visit this blog with any regularity, you might have guessed that I'm fascinated — some might even say obsessed — with images of the sun. The mind-blowing image above should show why. Captured by NASA's Solar Dynamics Observatory, it shows a...

Fifteen years ago, a small cabal of researchers took some of the most firmly held notions about how the universe works and turned them on their head. Until then, everyone was sure that the expanding universe was born in an explosive Big Bang and had ...

The Cassini spacecraft has provided NASA with the first visible-light glimpse of a massive weather system circling Saturn’s north pole. The spinning storm is 20 times larger than the average hurricane on Earth. Cassini detected a vortex-like weath...

At any given moment, the sun features material leaping off the surface in arcs, flares and ejections. That's dynamic enough, as previous posts here at ImaGeo have illustrated. (Check out this this one, for  example.) But what would a composite of ...

Astronomers are expecting a lot out of Comet ISON. Due to pass incredibly close to the sun on November 28 of this year (700,000 miles from the star's surface), the frozen rock will make for a stunning sight, potentially outshining even the full moo...
