Radar imaging of asteroid 2005 YU55 showed that the asteroid is about 1,300 feet (400 meters) in size and about twice as large as previously estimated.
On May 18, the Japan Aerospace Exploration Agency (JAXA) says, it will launch into space a “solar yacht” called Ikaros—the Interplanetary Kite-craft Accelerated by Radiation of the Sun (named, of course, in honor of Icarus in Greek mythology). JAXA plans to control the path of Ikaros by changing the angle at which sunlight particles bounce [...]
If you’re in LA this weekend, and you love SciFi and mad scientists — and c’mon, who doesn’t? — then you’ll want to attend the screening of "Monsters from the Id", a documentary on mad scientists, 1950s movies, and the future of science in the US. Seriously, check this video out and tell me you [...]
There are millions of asteroids in the asteroid belt between Mars and Jupiter, but yesterday attention focused on just one. According to a couple of studies in Nature, a large asteroid called 24 Themis is rife with water ice and organic molecules, and the researchers say that it could be more evidence that the water [...]

It’s part of a new segment on Skepchick called Keep your day job: Amy is a cool chick: artistic, skeptical, tattooed, photographically inclined, and loves astronomy. I got to hang with her and other skepchicks last week in Pasadena, and [...]
I used to write for the Huffington Post, before it became overrun with antiscience alt-med antivax garbage so thick I could smell it through my monitor.
Case in point would be a somewhat targetless essay by Dr. Larry Dossey, who seems to be trying to say that because science is portrayed as an individual effort, but [...]
Wow — this looks HUGE from orbit — can you imagine standing out in the Sahara Desert and seeing this gigantic wall of dust heading right towards you? The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite observed this wall of dust on April 22, 2010 which spans hundreds of kilometers. See [...]
Our series "13 Things That Saved Apollo 13" has raised a few questions for some of our readers about spacecraft design, decisions made during the Apollo program, and general questions about spaceflight. Some of you have already left questions as comments on the articles or sent in emails. NASA engineer Jerry Woodfill, who [...]
We usually think of asteroids as dark, dry, lifeless chunks of rock, just like the image of Asteroid Itokawa, above. But some asteroids may be more like "minor planets" after all. Researchers have found evidence on one asteroid – 24 Themis – of water ice and organic materials. This discovery is exciting [...]
I’m on the road today, so I don’t have time to explain the fascinating science behind this freaky new picture of feathered dinosaurs young and old. So let me just direct your attention to fellow D-blogger, Ed Yong, and Nature’s Janet Fang for more.

The Hubble Space Telescope is one of the greatest technological achievements in our history, and for two decades has astonished us with dynamic images of our solar system and the world beyond. To celebrate this important twenty-year milestone, NASA looks back at the contributions of this extraordinary scientific tool, and the scientists who created it, [...]
Apollo 11 Saturn V Launch (HD) Camera E-8 from Mark Gray on Vimeo.
This is so cool – and impressive, most impressive! A 16mm camera located near the base of the Saturn V rocket captured incredible detail about the ignition and lift off of the Apollo 11 mission to the Moon. The high-quality video [...]
The most prominent of the galaxy formation models predicts that galaxies are built up from the merging and accretion of many smaller galaxies that orbit within their gravitational sphere of influence.
A switch-out of the magnet for a much anticipated particle physics experiment on the International Space Station will force NASA to delay the final flight of the space shuttle until at least November, and change which orbiter and crew will fly the final space shuttle mission. The $2 billion Alpha Magnetic Spectrometer was scheduled [...]
While most newborn stars are hidden beneath a blanket of gas and dust, the Planck space observatory – with its microwave eyes – can peer beneath that shroud to provide new insights into star formation. The latest images released by the Planck team bring to light two different star forming regions in the Milky [...]

Happy 20th Birthday to the Hubble Space Telescope! While we should be showering HST with gifts, instead the telescope provides this present to us: an amazing view of what has been nicknamed "Mystic Mountain. " It is just a small portion of one of the largest known star-birth regions in the galaxy, [...]
Everything in the Universe is spinning. In fact, without this rotation, life on Earth wouldn't exist. We need the conservation of angular momentum to flatten out galaxies and solar systems, to make planets possible. Let's find out about the physics involved with everything that spins, and finally figure out the difference between centripetal and centrifugal [...]
