#NASAWebb researchers have made major strides in confirming the source of dust in the early universe with observations of two dying stars (supernovas!): https://webbtelescope.pub/3CRzTnL

Like many other scientists I often get "debate me" emails from random people with weird ideas about #astronomy. If I answer, they feel validated. Same if I don't. So I always pick the option that doesn't waste my time. Don't fall for the "debate me" trap, folks, you can't win. #scicomm

I was a NASA intern in the '80s when I heard that astronomers had discovered a mysterious disk around the nearby star Fomalhaut.
Now JWST has revealed exactly what they are: three enormous, dusty asteroid belts around another star!

The first #NASAWebb results from TRAPPIST-1 are in! Measurements of mid-infrared light from TRAPPIST-1 b indicate that the rocky Earth-sized planet is hot enough to bake pizza and is probably devoid of atmosphere. What does this mean? ➡️ https://webbtelescope.pub/3nlCcLc

For good #astronomy lectures aimed at general audiences, look at The Silicon Valley Astronomy Lecture Series; see link to YouTube via
https://foothill.edu/astronomy/

(There I first attended a lecture on discovering exoplanets by Dr Geoff Marcy in 1996, which predated the series by a few years.)

For me, one thing that makes a lecture good is hearing what a speaker finds interesting about a subject.

Here's a picture of the Sun today that I took in hydrogen alpha. Compare that to a picture taken by NASA's Perseverance Rover a few hours ago with its Mastcam-Z. Sunspots 3216 (far-left) and 3214 (left) are visible on both. Even relative sizes check out.

For the first time, astronomers using Hubble have directly measured the mass of a single, isolated white dwarf—the surviving core of a burned-out Sun-like star: https://bit.ly/3X3CcMo

ALMA tiramisu. A desert dish dessert dish, if you will

A reminder to everyone in #Ireland interested in #astronomy that tonight there will be an #occultation of the entire sky by cloud.

I hope this clarifies the situation.

My gingerbread creations from the past two years. Any ideas for what I should try this year?

For this year's gingerbread I made... Curiosity!

Guess I can post these now.

Check out those views! 😎

It's always a treat to open the observatory dome—and not just for our staff who get these views firsthand!

...even our commissioning camera friend gets a peek 👹

55 years ago #today Jocelyn Bell discovered the first known pulsar -- a star the size of a city, spinning once a second, whipping up intense radio signals that sounded like the beep-beep-beep of an alien signal.

In her own words: https://www.cam.ac.uk/stories/journeysofdiscovery-pulsars #astronomy #discovery

British designer Peter Saville created the cover for Joy Division's "Unknown Pleasures" inspired by a pulsar radio-wave pattern that astronomer Harold Craft published in his PhD thesis.

Could that be the most widely seen PhD thesis in history?

@mcnees @antonioserrata Miss Jocelyn Bell Burnell The Cat approves of this toot. (My kitty was the last of a litter of kittens from a feral mom, fostered by a grad student who named all the kittens after female scientists the grad student thought needed to be better known.) #catsofmastodon #cats #astronomy

A group at Johns Hopkins has created a scrollable, interactive map of the entire universe, from here to the cosmic microwave background.
