So we’re still where we were two weeks ago: Betelgeuse might explode tomorrow. It might explode a hundred thousand years from now. But if it does explode soon, we will get the best look we’ve ever had at how stellar explosions work.
I was peripherally involved in this research, which detected some of the highest energy photons every seen from a gamma-ray burst.
GRBs are dangerous. They can kill. But it’s rare. There is one candidate nearby that could be dangerous. But we’re still figuring out whether it is.
I checked the calculations myself and this does appear to be accurate…
Yes, there are stars within a few hundred light years that will go supernova. No, we don’t have any way of predicting when it will happen.
In the decades to come, we’re going to learn a lot about alien planets. It would not surprise me at all if we found ones like New Caprica or Arrakis.
A new treatment for Ebola, if administered early, can cut the fatality rate to 6%, a stunning reduction from the normal rate of 75%. We now have this and a working vaccine.
I’m not one of the “we have 12 years to save the planet” doomsayers. But it does feel like we are approaching an inflection point. We will survive; but our options for how we will survive are narrowing rapidly.
I really hope to live long enough to discover that we aren’t completely alone, even if the neighbors are only one-celled organisms.
If Musk’s full system comes on line, the simple fact is that no one has done the kind of careful study needed to figure out the impact of this constellation.
Even with three nuclear disasters, the number of casualties is tiny. And it is especially tiny when compared to the environmental and human cost associated with fossil fuels.
Scientists need our own version of Rule 34: if it exists, someone is studying it.
Black holes were first theorized in the 18th century. But because they are…you know…black…we couldn’t image them directly. Until now.
This entire nontroversy is a result of two things colliding: one good and one bad. The bad part is that NASA’s spacesuits were built in 1978, The good part is that NASA has recruited more women.
