Since I am still quite new here on Mastodon, I should introduce something I have been working on, and off, for a very long time. Since 2003 (one hear before Facebook was founded, and three years before Twitter came into existence), I started a photoblog, where I posted longer-form stories about my photos and travels. You are welcome to check it out at http://photoblog.ornitorinko.org/

The latest post (restarted after a long hiatus) is about my move to Florida from Iowa

Weather is nice again after the deep freeze of last week (yes we went below freezing even in the Florida panhandle), so we went for a walk around Lake Lafayette (Tallahassee, FL). #Samoyed #Florida #Tallahassee #Lake #Landscape #Photography #iPhone #Dogs #DogsOfMastodon

Fred Lawrence Whipple Observatory (FWLO) telescopes as seen from the summit of Mt. Hopkins (where the MMT telescope is located). The observatory is managed by the Smithsonian Astrophysical observatory (SAO). The three domes host the 60- and 48-inch telescopes, and the PAIRITEL 1.3 meters telescope (left to right). At the bottom left are the "ridge" dormitories for the astronomers and staff. From an observing trip in December 2005. #Astronomy #Telescopes #FWLO #Whipple #Arizona #Photography

There are many astronomical observatories in Chile, several of them in the Norte Chico region, near La Serena. Two of them are so close that you can see one from the other. This is a view of the European Southern Observatory (ESO) telescopes (white dots on the far mountain range you can see if you enlarge the photo) from Las Campanas Observatory. I miss the colors of the Chilean high desert mountains... #Astronomy #Telescopes #Photography #Chile #LasCampanas #LaSilla #Mountains #Desert #Photo

5/ Last but not least, Earendel, the fartest star ever observed, at redshift 6.2 (e.g. so far away that its light has taken 12.9 billion years to reach us). The star was found thanks to gravitational lensing, a general relativistic effect that helps magnify the light of distance objects when it is distorted by a nearby mass (in this case a cluster of galaxies). Talks today show that we will find more of those. Read more about Earendel on the original NASA press release: https://www.nasa.gov/feature/goddard/2022/record-broken-hubble-spots-farthest-star-ever-seen

4/ The science talks in the afternoon were about the high-redshift discoveries that are being made by JWST in his first 6 months of operations: in short, it looks like galaxies (and their supermassive black holes) seem to form much faster than cosmological models predict. Also, images of galaxies with redshift up to ~12 (when the first stars were born ending the "dark ages" characterizing the early universe).

3/ And this despite a "big" impact of a micro-meteorite that damaged one of the segments of JWST primary mirror. Even though the impact did cause some image degradation, the overall system works so well that more than compensate for the damage. To reduce the risk of such impacts from now on, whenever possible, the telescope will observe "backward" with respect to its sense of motion: this will put the spacecraft at the back the telescope between the "rain" of micro-meteoroids and the mirror.

2/ The meeting started today and will continue until Wednesday (Dec 14), and the program is available online: https://www.stsci.edu/files/live/sites/www/files/home/events/event-assets/2022/_documents/JWST%20Conference%20Agenda%2012.9.22.pdf

This morning talks were about the performance of the various instruments onboard the spacecraft, and of the telescope itself. The good news is that everything is working better than expected: we can see finer details and fainter objects that JWST was designed for.

1/ If you want to watch astronomers talk about the new exciting science that is being done with NASA's JWST telescope, you can remotely follow the meeting that started today in Baltimore on "First Science Results from JWST". All talks are streamed on the Space Telescope Science Institute (STScI) YouTube channel: https://www.youtube.com/channel/UCz9piVEpww5SibUdrRSOl-Q/featured

Judging from the clarity of the sunset, it must have been a good observing night. That trip was dedicated to find MACHO events: small stars by chance align in front of other stars farther away, acting as "gravitational lenses". This is a phenomenon predicted by Albert Einstein, and observed for the first time in May 1919 when the light from stars was observed to be "bent" by the gravity of the Sun, proving right the theory of General Relativity.

Since people seemed to like the photo of the telescopes in the Las Campanas Observatory I used in my introduction, here is another image I took during the same observing trip. This is the Baade telescope, part of the twin Magellan telescopes. With an aperture of 6.5 meters (diameter of the primary mirror) , these telescopes are now "mid size" when compared with the 30+ meter aperture monsters now in construction. #astronomy #photo #photography #chile #telescope #observatory #sunset

Early December view from my backyard, here in Tallahassee. One thing I like of my new neighborhood is despite being quite close to the Midtown and city center, it is like living in a forest, surrounded by the "canopy roads" the town is famous for. #tallahassee #fog #photography #pinetrees

In case somebody is wondering what king of research I do for my job, I am a stellar astronomer. I study galaxies (like our own Milky Way in the picture below, but others too) by means of their stars. In particular pulsating stars that I use as probes for the structure, evolution and chemical composition of galaxies. I do that as an observational astronomer, which means I use data from telescopes, from space and the ground. #astronomy #milkyway #astrophotography #nightsky #stars #photography

This is again the time of the year when we shoot holidays picture to send to family and friends. Also the time of the year when the little one decides to put on the full-on camera attitude.

#introduction Hello Mastodon. I an astronomer, recently moved to Florida State University where I am professor pf physics and astronomy. I study the universe by means of its stars. While I normally work on fantastic images from the sky as a job, I also enjoy taking photos of what I see around me, on this little planet we call Earth. Expect posts about science, photography, and society in general. And here is a photo that combines both astronomy, and Earth (Las Campanas Observatory, Chile).
