7:00 PM | Astronomy Video of the Week: Watch the March 20th Total Solar Eclipse Live!
A partial solar eclipse as seen from space. (Credit: NASA/SDO). It is now almost upon us. The first eclipse of 2015 and the only total solar eclipse of the year is coming right up this Friday on March 20th, as the shadow of the Moon crosses the North Atlantic. And although the path of totality [...]

6:59 PM | U.S. hurricanes begin in western Africa’s atmosphere
Hurricanes require moisture, the rotation of the Earth, and warm ocean temperatures to grow from mere atmospheric disturbances into tropical storms. But where do these storm cells originate, and exactly what makes an atmospheric disturbance amp up full throttle? A new study accepted for publication in Geophysical Research Letters finds most hurricanes over the Atlantic Ocean that eventually make landfall in North America actually start as intense thunderstorms in western Africa.

3:30 PM | Does Astrology Work? I’m Gonna Go With “No.”
Of all the pseudoscience still pervading the human brain, astrology is probably the oldest. As I point out in an episode of Crash Course Astronomy, millennia ago it kinda made sense; there were cycles to the stars and the seasons, and with our lives so tied to agriculture and weather, it was natural to suppose the stars affected us in other ways. But now, after centuries of scientific investigation, we know better. Or we should. Apparently, we still don’t. Astrology still gets a lot of […]

2:22 PM | "Mini Supernova" Explosion Could Have Big Impact
In Hollywood blockbusters, explosions are often among the stars of the show. In space, explosions of actual stars are a focus for scientists who hope to better understand their births, lives, and deaths and how they interact with their surroundings. Using NASA's Chandra X-ray Observatory, astronomers have studied one particular explosion that may provide clues to the dynamics of other, much larger stellar eruptions. A team of researchers pointed the telescope at GK Persei, an object that […]

2:21 PM | L’oceano sotterraneo di Ganimede
Il telescopio spaziale Hubble ha permesso di avere la miglior evidenza indiretta che riguarda l’esistenza di un oceano di acqua salata sotto la superficie di Ganimede, la luna più grande di Giove. Secondo gli scienziati, l’oceano sotterraneo conterrebbe una quantità d’acqua superiore a quella presente in tutti gli oceani della Terra. In generale, sappiamo che trovare l’acqua allo stato liquido … Continue reading […]

1:44 PM | Mostly Mute Monday: A final view from the Moon (Synopsis)
“Curiosity is the essence of human existence. ‘Who are we? Where are we? Where do we come from? Where are we going?’… I don’t know. I don’t have any answers to those questions. I don’t know what’s over there around the corner. But I want to find out.” -Eugene Cernan, last human on the Moon…

11:00 AM | Politics Is Poisoning NASA's Ability to Do What It Needs to Do
Well, I told you so. When Ted Cruz (R-Texas) was made head of Senate committee in charge of NASA’s funding, I (and many others) were appalled. Cruz is a science denier, flatly claiming global warming isn’t happening. This is an issue, since many of NASA’s missions are directly focused on examining the amount, extent, and impact of that warming. And rightly so. While Cruz may not be able to directly impact NASA’s budget, he can certainly make things difficult on the […]

This was originally published 8/23/2011.  More should have changed by now.  This is a sort of permanent redux.Today is my birthday, a good time to reflect. And one of the things I have found myself brooding over lately is my love of Baltimore. As fans of The Wire know, the city has more than its […]

4:00 AM | La deflessione ‘quantistica’ della luce
La luce che passa in prossimità di un oggetto astrofisico viene deviata dalla sua traiettoria rettilinea a causa del campo gravitazionale che esso esercita. Per un corpo celeste massivo come il Sole è possibile misurare questa deflessione: ad oggi, le migliori osservazioni indicano un valore di 0,00049°, in accordo con la relatività generale. Oggi, Niels Bjerrum-Bohr … Continue reading La deflessione ‘quantistica’ della luce →

9:01 PM | Weekend Diversion: The Ultimate Science in your Science Fiction (Synopsis)
“The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.” -Isaac Asimov Yet it’s that intersection — of science with our day-to-day lives, our imaginations, our hopes, fears and dreams — that’s going to be the thing that drives us towards a scientifically literate future. Have a listen…

7:56 PM | Looking for Life in All the Wrong Places?
The past couple weeks have seen a brain-sparking series of discoveries that advance the search for life beyond Earth. Enceladus is emitting burps of methane, which strongly indicate the presence of a warm ocean under its ice (and which could, just possibly, hint at biological activity down there). Ganymede seems to have its own buried ocean, one that may contain more water than all of Earth’s oceans combined. A new study shows that organisms could potentially evolve in the frigid methane […]

11:30 AM | What Causes an Aurora?
I write a lot about aurorae, the lovely and eerie glowing lights at extreme latitudes caused when subatomic particles from the Sun are channeled down into the atmosphere by Earth’s magnetic field. Whenever I do I always wind up having to write a brief explanation of how they work; that’s the responsibility of a science writer. But my burden is now eased a bit thanks to this well-done video giving a solid overview: What I like about the video is that it covers the basics without […]
