A reminder, because it is almost that time of year: More children are killed by cars on Halloween than any other day of the year, by far. www.vox.com/future-perfe... If you're a parent, I hope you'll do what you can to keep kids safe. If you're driving on Saturday, PLEASE exercise extra caution.

Join me Thurs, Oct 29 at 6:30pm at Caffè Classico in Pompton Plains, NJ, for “Bird Migration: The Journey Through New Jersey!” Explore the Atlantic Flyway, bird photography & backyard birding tips. Registration required info@thebackyardbirdingstore.com #NJBirding #BirdMigration @aba.org @nature.org

I created this photo using recent research so it relaxes your brain when you pause to look at the details. As I'm sometimes too unwell to post here (not good mental health due to PMDD & recovering from a breakdownA) it would help so much if you could maybe RT my photo. Many thanks 🌿

The dielectric constant is just a multiplier. A vacuum is exactly 1. Dry air is 1.00059. Rubber is 3.0, so a rubber dielectric gives you 3 times the capacitance a vacuum would. That is all it tells you. youtu.be/KL-GfLDGmN8 #iTeachPhysics #Physics #Science #EduSky #APPhysics

Test images of the full Moon last night to determine exposure bracketing for the 8/2/26 total eclipse. I made a regular and mineral Moon with the 1/8000s exposure, ISO 100. My next step will be working out the max unguided exposure by imaging stars at the same 18 deg declination. #astrophotography

A spectacular X-ray tribute to a fantastic NASA mission. Swift has perhaps weeks left before it burns up during re-entry to Earth's atmosphere, after two decades of chasing the universe's biggest stellar explosions. badastronomy.beehiiv.com/p/an-x-ray-t... 🔭 🧪

I appreciate all the nice comments on the new webcam page I have developed! I am working on some new tools beyond the webcams page as well, so stay tuned for that. theauroraguy.com/pages/webcams

Moonrise tonight, sped up. #astrophotography

Trump turned Sagan’s prediction into a reality.

This was Yandy Diaz's face when my former student Hunter Bigge gave me a shout out on the Rays Teacher Appreciation Day video in May. Yandy's stats during the playoffs show he knows more than enough about physics. You can see the whole video here: www.instagram.com/reel/DX9-Cwv... #ITeachPhysics

#Spacetober day 23: nebula. An Earth-type planet near the Horsehead Nebula. A cloud of gas is emitting red light, with a dark, absorbent cloud, in the shape of a Horsehead, superimposed in front of it. This is a digitally modified version of a painting I did in the 1990s. #SciArt #spaceart

OTD in 1975 a machine from Earth took the first photo ever from the surface of another planet. Venera 9 at Venus. 🧪

HFG1 and Abell 6 (lower left) are planetary nebula. At HFG1's center is a binary white dwarf and sun-like star. They are hurtling through the galaxy creating an OIII bow shock and leaving an h-alpha tail. The nature of the bright pink knot at 2 o'clock is uncertain. Details in ALT #astrophotography

Someone must have been having a bad day when they named this one. LDN 1251, the “Rotten Fish” Nebula. Doesn’t really convey the beauty of the cosmos vibe. Nevertheless, LBN 438 is a beautifully faint dark nebula in the constellation Cepheus. 🔭 #astrophotography ~8 hours UV/IR

I couldn’t find a video showing the classic oil drop and ruler to estimate the size of an atom so I made this one yesterday. I use it as part of my A-level physics induction taster lessons: youtu.be/7WoKdnnHoCg #ITeachScience #SciTeachUK

While in town for a funeral, I went for a walk and stumbled upon the 113 year old Witch’s Hat Water Tower. It is located on the highest point in Minneapolis. Nice view of the city on a perfect fall day.

#Spacetober day 19: Saturn In this artwork we find ourselves floating within the ring system of the gas giant, Saturn. The ring particles are made almost entirely of water ice - which is why they are so bright - and range in size from about a centimetre to a few metres across. #SciArt #blender

This is simply fantastic

One of the many things I love about El-Sayed is that he's willing to engage with someone hostile if it gets them to admit the premises behind that hostility, to the extent that it becomes impossible to avoid the underlying bigotry. You want to go there, fine, but he's gonna make you own it.
