Wed. Aug. 14 - The Weather Looks Good Tonight So Far, But Check Back Later For Our Final Weather Decision.

We'll be closed tonight, Wednesday Oct. 11. We expect up to 70% cloud coverage depending on which forecast you believe, and the satellite images look terrible.

HOWEVER keep an eye out this Saturday for the solar eclipse! If the weather is clear, we'll start giving out information and eclipse glasses around classes at 10:30 am and set up some solar telescopes on the observing decks. The eclipse lasts from12:18 to 2:34 pm. In the case of clouds, we'll only stream the eclipse in the lobby on the first floor.

NASA’s Webb Snaps Supersonic Outflow of Young Star

This image of HH 211 from NASA’s James Webb Space Telescope reveals an outflow from a Class 0 protostar, an infantile analog of our Sun when

Take-aways:

This is a baby star imaged in stunning detail

Stars are born violently - there's hot gas striking the other gas and dust around it, making these amazing patterns

This particular baby star will one day be like the Sun 💖

3/19: Our public night is cancelled. The forecast keeps getting worse. We'll try again next week!

PDS 70: Disk, Planets, and Moons Image Credit: ALMA (ESO/NAOJ/NRAO); M. Benisty et al.

Explanation: It’s not the big ring that’s attracting the most attention. Although the big planet-forming ring around the star PDS 70 is clearly imaged and itself quite interesting. It’s also not the planet on the right, just inside the big disk, that’s being talked about the most. Although the planet PDS 70c is a newly formed and, interestingly, similar in size and mass to Jupiter. It’s the fuzzy patch around the planet PDS 70c that’s causing the commotion. That fuzzy patch is thought to be a dusty disk that is now forming into moons – and that had never been seen before. The featured image was taken in 2021 by the Atacama Large Millimeter Array (ALMA) of 66 radio telescopes in the high Atacama Desert of northern Chile. Based on ALMA data, astronomers infer that the moon-forming exoplanetary disk has a radius similar to our Earth’s orbit, and may one day form three or so Luna-sized moons – not very different from our Jupiter’s four.

Each fall and spring season, we host a set of public observatory nights on Wednesday evenings. This spring, we're set to start on March 19, weather allowing. Schedule coming soon!

Imaged in luminance and photometric R, V and B filters. Total exposure time ~25 minutes.

The Black Eye Galaxy (M64) is a relatively nearby spiral with an extraordinary amount of dark dust partially obscuring its nucleus. Red hues peeking out in these dust lanes are caused by reddening when the dust scatters the bluer light from stars embedded within it. The color difference between the center and spiral arms is due to an average age difference between the stars in these locations--blue stars have short lives, so as the star population ages the overall color appears more red.
