Readers’ wildlife photos

I hope you like birds (who doesn’t?), as we have several today. First are two photos of the house finch (Haemorhous mexicanus) by Stephen Barnard in Idaho. I get lots of these on my lab windowsill, competing with the squirrels for sunflower seeds: Finally some sun, but it’s cold. We’ve had about three feet of snow. […]

Readers’ wildlife photographs

I’ve included a couple of landscapes in today’s photographs, and thanks to the many readers who sent me photos over the holidays. This lovely photo is by Rick Wayne: My previous wildlife photo submission included an elk strolling along Yellowstone Lake. So I have to include another picture of Yellowstone Lake, but this is the one in […]

Readers’ wildlife photographs

The tank of readers’ photographs is running seriously low, even though I’ve recovered many of the lost ones, so please send in your good pictures ASAP. Otherwise we’ll run out in a week or so. Today is Insect Day, with Moon Lagniappe. Reader Mark Sturtevant sends his always lovely photos of insects; there are three […]

Readers’ wildlife photographs

Today have some more photographs of Africa from the many sent me by reader Benjamin Taylor. His captions are indented: African leopard (Panthera pardus pardus), Okonjima Nature Reserve, Namibia: Damara ground squirrel (Xerus princeps) or possibly the Cape ground squirrel (Xerus inauris): South African cheetah (Acinonyx jubatus jubatus), Okonjima Nature Reserve, Namibia: The Milky Way: African savanna elephant […]

Readers’ wildlife photos

Reader John Crisp in Ethiopia sent a bunch of photos; I’ll present only a few today and ration the rest over time. All these photos were taken between 6 am and 8.30 am this morning [Nov. 22] on Lake Tana, Western Ethiopia, where I have lived for the last four years. I hope the captions are self […]

Readers’ wildlife photographs

We have several contributors today; the first is Anne-Marie Cournoyer from Montreal: These photographs were taken at at the Parc National du Mont St-Bruno (on the south shore of Montreal), and the last squirrel (the one with the nuts) was taken in Brossard. While walking close to a lake, we saw some turmoil on the water, […]

Readers’ wildlife photographs

We have a diverse set of photos today, including a dramatic rescue of a raptor by one of our regulars. First, Dave Molloy from Oz sent some photographs of the evening sky and of wombats: I knew there was a planetary conjunction to be seen in the dawn sky for the last few weeks. However, surprisingly for the eastern […]

NASA animation: black hole sucks in passing star

On the NASA site you can find this description of a new piece of research about a star encountering a black hole, and observations from X-ray spectral analysis of what happened when it did. Predictably, the results are dramatic, though some of the star stuff doesn’t get sucked all the way in. I haven’t read the paper (reference […]

Readers’ wildlife photos

Today we have a grab-bag of diverse photos from several readers, some sans wildlife. The first is from Brandon Cooper, who collaborates with my ex-student Daniel Matute collecting Drosophila flies in Africa: I recently returned from Zambia, Malawi, and Namibia where Matute and I collected a nice transect of melanogaster and simulans. While collecting in […]

Big announcement by NASA about Mars today: 11:30 a.m. EDT

Reader Tom C. calls our attention to a big announcement today, and he speculated a bit about it: There’s a NASA press conference regarding something cool on Mars at 11:30 EDT.  I’m hoping for HD images of brachiopod-like fossils embedded in a dry stream bed, but I’ll bet on the discovery of liquid water on […]
