The Cosmos - Celestial Objects
Our universe contains an amazing array of celestial objects, sometimes referred to as celestial bodies or astronomical objects.
Mars Science Laboratory
With its rover named Curiosity, Mars Science Laboratory mission is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet. Curiosity was designed to assess whether Mars ever had an environment able to support small life forms called microbes.
Mars Greeley Haven 360 Panorama
This is the latest panorama released by NASA July 2012. It was assembled from 817 images taken between Dec. 21, 2011, and May 8, 2012, while Opportunity was stationed on an outcrop informally named 'Greeley Haven'. on a segment of the rim of ancient Endeavour Crater.
If one could know whether among that glittering host there were here and there other spirit-inhabited grains of rock and metal, whether man’s blundering search for wisdom and for love was a sole and insignificant tremor, or part of a universal movement!
Monster Saturn Hurricane
Monster Saturn Hurricane Recorded by NASA - NASA's Cassini spacecraft captured high-resolution pictures of a large, mysterious hurricane over Saturn's North Pole. The eye of this huge storm is 1,250 miles across with cloud speeds as fast as 330 miles per hour.
The fury of our sun captured in ...
The fury of our sun captured in never-before-seen detail - Normally it's harmful to stare at the sun, but for researchers at the NJIT’s Big Bear Solar Observatory, that's their job. Stripping away the danger with its New Solar Telescope (NST), the team used its newly-equipped spectrometer to help capture the clearest images of the sun's atmosphere to date, discovering never-before-seen features within the star at the center of our solar system.
Big Bang to Now in 10 Easy Steps
The broadly accepted theory for the origin and evolution of our universe is the Big Bang model, which states that the universe began as an incredibly hot, dense point roughly 13.7 billion years ago. So, how did the universe go from being fractions of an inch (a few millimeters) across to what it is today?
Weird, Out-Of-Whack Exoplanetary ...
Weird, Out-Of-Whack Exoplanetary System Discovered - Scientists have been using data collected by NASA’s now-defunct Kepler space telescope not only to look for planets beyond the solar system but also to probe their parent stars, which pulsate as they spin, causing variations in brightness.
What's the weather like on Titan?
What's the weather like on Titan? 'Salt flats' provide new clues - Fresh images of the hydrocarbon lakes on Titan reveal what appears to be the extraterrestrial equivalent of salt flats — a discovery that adds yet another layer of mystery to Saturn's largest moon.
What space jellyfish tell us ...
What space jellyfish tell us about interplanetary travel - Back in the 1990s, when we had the space shuttles available for ferrying stuff into orbit, we sent jellyfish into space. Then, it seemed almost comically simple to come up with a science experiment. Pick an object or living thing, launch it into orbit, see what happens. But it wasn’t as easy as it seemed. For NASA to accept your proposal, you had to have a good reason for it—you couldn’t just send anything up there.

In 200 million years days will be 25 hours long - Wish you had another hour in the day to get everything done? Just wait 200 million years, when days here on Earth will stretch to 25 hours.
Water found in stardust suggests...
Water found in stardust suggests life is universal - A sprinkling of stardust is as magical as it sounds. The dust grains that float through our solar system contain tiny pockets of water, which form when they are zapped by a blast of charged wind from the sun.
Is Distant Galaxy Milky Way 'Baby'?
When searching for galaxies to study, it is easiest to pick out the biggest and brightest. This is especially true if you want to look at very distant galaxies; ones that were around when the Universe was very young. It is quite a challenge to pick out a faint, normal, almost “boring” galaxy from a time long ago, but when astronomers used the 10-meter Keck telescope to do just that, it was pretty exciting.
Ancient Mars Was Habitable For ...
Ancient Mars Was Habitable For Hundreds Of Millions Of Years, Old Rocks Suggest - Mars may have once been capable of supporting microbial life for hundreds of millions of years in the distant past, new findings from a long-lived Red Planet rover suggest.
Are We Really All Made of Stars?
"We are a way for the universe to know itself. Some part of our being knows this is where we came from. We long to return. And we can, because the cosmos is also within us. We're made of star stuff," Sagan famously stated.
12 Diagrams That Changed How We ...
These days, we are treated to glorious images of the cosmos through astrophotography and sophisticated three-dimensional visualizations of the universe. In the early centuries of astronomy, however, our visions of the cosmos often took the shape of diagrams—representing what we believed about our solar system.
Beyond Energy, Matter, Time & Space
Though he probably didn’t intend anything so jarring, Nicolaus Copernicus, in a 16th-century treatise, gave rise to the idea that human beings do not occupy a special place in the heavens. Nearly 500 years after replacing the Earth with the sun as the center of the cosmic swirl, we’ve come to see ourselves as just another species on a planet orbiting a star in the boondocks of a galaxy in the universe we call home ...
Rotating Moon Video and Images
The video, a patchwork of images of the moon's various surfaces at their peak of solar illumination, ‘shows that there is no dark side of the moon — there's a far side,’ scientist Noah Petro says.
