Not a good picture, but all I had was my mobile phone.  There are four elks in this picture taken in the Canadian Rockies Friday, about 50 meters away.

Totally off-topic thread

I had a very brief visit to the Canadian Rockies today.  Got to Lake Louise, but had to get back to Calgary by 2 pm.  Looks like a nice area to hike in summer, if it's possible to escape the crowds. 30420501_10155737901756443_2805253925429291188_o.jpg 30420501_10155737901756443_2805253925429291188_o...

Science and Astronomy Questions

19638 What's further interesting is that this knowledge of exoplanets mostly arose just in the last 20 years.  The next 20 will be even more revealing, especially as we begin to characterize the atmospheres of terrestrial exoplanets! We're in a golden age for finding answers toward what is possibly...

In this discussion I think it's useful to distinguish between marine life and land life.  Whlist the environment at the surface may be too hostile to support life as we know it, oceans may still have benign conditions.

Unusual weather

Looks like a nice beach, when the weather is more fair. We've finally got normal spring weather here. Only 89 cm of snow to go, which should take another 2 to 4 weeks depending on the weather. And I'm off to Calgary this weekend. When I checked the weather there a few days ago, it said -15C which se...

Science and Astronomy Questions

I'd rather ask, would evolution at all work if there were no aging? As for breathing CO2, we breathe to be able to fuel chemical reactions that give us energy, so to breathe CO2 there must be something that chemically reacts with CO2 releasing energy, so our diet would have to change radically from ...

A quick panorama taken 1. April in Jotunheimen, Norway.  Easter as it should be!  Not a single cloud for a week, extremely dry air, and no wind.  -30C at night, peaking to -10C during the day.  And my skiing through this landscape in the bright moonlight a couple nights before was something to remem...

I took these two images on the same trip, really. 8000 km, 54 degrees centigrade and just over 24 hours separate them.  That was a long trip and the contrasts could hardly be larger.  Unusually warm for the season in Mountain View California (+27C), and unusually cold for the season in southern Norw...

Fascinating picture.  That doesn't look safe... Much bad weather at the northern coast of Norway recently.

Ooh, I searched for "dark gravity" and found that deGrasse Tyson makes my point precisely in a fine way.

Well, sorry for picking on dark matter so much.  Maybe I just don't like the name.  A better name could be "dark gravity", since gravity is what's being observed, not matter, which is only one cause of gravity but not necessarily the only one.

It's slightly worrying that whenever theory doesn't match observation, the reflex is "it's dark matter/energy"!  On the other hand, the more times scientists play that card, the more has to be consistent, which either means that we can better explain dark matter/energy or that the explanat...

Total Solar Eclipse 2017

Nice.  But you can easily remove the remaining noise.  For instance, try experimenting with selective gaussian blur in Gimp.  Use a low threshold in the center, and a higher threshold for the remaining area.

We have a meteor camera not far from Abisko, but I discovered that the file server's smbd process had stopped, so nothing was recorded.  The spooky thing is that smbd had stopped at the very same time on half of our servers across the country.  I've never seen it stop unexpectedly before.  And certa...
