3:02 PM | Of space capsules and Cookie Monsters
On Friday, NASA performed its latest test of the Orion capsule, the next-generation spaceship that will carry human crews. Since the long-overdue retirement of the Space Shuttle, the United States space program has relied on Russia to get astronauts into orbit. But Orion is more than a Space Shuttle replacement: it’s intended to travel beyond […]

12:00 PM | Soaring: Lights Over Norway
For years, I thought that aurorae—the northern and southern lights—were pretty stately phenomena. Sure, there were sheets and ribbons colored green and red and pink and purple, so it was clearly a flamboyant and amazing display. But having seen so many static pictures, and then time-lapse videos, I got the impression that aurorae didn’t change rapidly. The motion was there, but slow. Then, earlier this year, I saw a video that showed the aurorae moving in real time, and I was […]

12:15 PM | Dawn Sees Ceres!
That picture may not look like much at first glance, but it’s actually very exciting: That is Ceres, the largest asteroid in the solar system, as seen by the Dawn spacecraft, currently on its way there for a rendezvous next spring! This picture was taken by Dawn’s framing camera when it was 1.2 million km (about 740,000 miles) from Ceres on Dec. 1, 2014. It’s a calibration image; a long exposure was used so stars could be seen, and Ceres was overexposed. A close-up is shown in […]

5:00 AM | La materia scura e i neutrini fossili ‘visti’ da Planck
Dal 2009 al 2013, il satellite Planck ha osservato la radiazione fossile, detta anche radiazione cosmica di fondo, che rappresenta la luce più antica che siamo in grado di osservare. Per la prima volta, la radiazione fossile è stata misurata in maniera accurata su tutto l’intero cielo, sia in intensità che polarizzazione, fornendo l’immagine più … Continue reading La materia scura e i neutrini fossili ‘visti’ da Planck →

“Nothing is too wonderful to be true, if it be consistent with the laws of nature.” -Michael Faraday And yet, it’s often incredibly difficult to use those laws of nature — even if they’re as simple as can be — to actually measure and quantitatively understand the Universe around us. Perhaps one of the most glaring…

11:30 AM | OK, Let’s Try This Again
Yesterday, a multitude of problems prevented the launch of NASA's Orion crew capsule on a Delta IV Heavy rocket, including a boat in the red zone (in the area downrange of the launch), high winds, and finally a problem with stuck valves in the fuel tanks. The second launch attempt will be at 12:05 UTC (07:05 Eastern time) Friday morning, Dec. 5. As before, the launch window is well over two hours long.  Update, Dec. 5, 2014, at 14:50 UTC: LIFTOFF! The Delta IV Heavy carrying Orion launched […]
