After a very busy two weeks (end of semester grading and then rush to submit a large proposal to NASA) I finally get to breathe a little (except, well my favorite mysterious star that started acting up again, see post in my "science" collection).

This is a photos from my trip to Arizona two weeks ago: a saguaro cactus blooming!

It turns out winter has finally ended in Iowa too. After a sunny weekend we have a somewhat heavy sky, and rain is on its way. But it is warm, and blooming.

I spent the day at the NOAO Kitt Peak observatory in southern Arizona. The tall tower is the home of the 4-meters Mayall telescope, now being prepared to host the Dark Energy Spectroscopic Instrument (DESI). DESI will study the effects of dark energy on the expansion of the universe, by measuring the distance of recession velocity of tens of millions of galaxies, ultimately building a 3D map of the universe.

End of semester means being so busy that social media takes the backseat. A few more weeks and I should be able to breath again... in the meantime, flying to Tucson via Dallas for a meeting. Not sure what us happening in Dallas but my flight is already delayed 1.5 hours, which will most likely mean I will miss my connection...

#MarchForScience in Des Moines. Iowa being Iowa the speaker on the podium when I arrived was extolling the virtues of industrial farming, GMO crops and the use of antibiotics. No mention about the issue of antibiotic resistance due to overuse of said antibiotics. That's Iowa for you...

We had persistent rain for the entire week, and the fields are pretty much all flooded. This is a corn field at the side of the road just outside town, along the Union Pacific railroad.
