This is globular cluster NGC 2419, also known as the Intergalactic Wanderer, found in the constellation Lynx, where globular clusters wouldn't normally be found. It orbits the Milky Way every every three billion years and its orbit takes it further than the Magellanic Clouds.

January 7th is National Old Rock Day! Well here is an old rock! These white circles are cross sections of Archaeocyathids. These were a type of sponge that built reefs during the Early Cambrian. This comes from the the Forteau Formation in southern Labrador, Canada. Over 516 million years old!

Global mean sea level rise amounted to 4.5 mm per year as a result of warming oceans and melting land ice, more than twice the rate of 2.1 mm/year observed at the start of satellite data in 1993, base...

There's a famous Feynman interview where he explains why ice is slippery. It turns out there's more to the story involving shear-stress and slippage of disordered ice layers. Things we experience every day still generate novel thought and research. #Science #Physics

A fairwell to #3I/ATLAS, the interstellar visitor, as now it is moving away both from the Sun and Earth. It has dimmed to about mag 12 and has a tail pointing towards the Sun. It will continue getting dimmer and won't be visible in just a few months. #cometWatch #astrophotography

When Star Trek the Movie came out back in '79 it had a much criticized sequence of shots where the camera basically drools over the Enterprise (1701A) in dry dock. But I was the target audience.

We got to the final listed track, track 15 "The Fate of Thomas Light" and it's the saddest bit of music I've listened to in awhile. Everybody in the Bandcamp livestream was devastated. This can't be the end of Act III. #Protomen #Music #RockOpera

I love #Quasars! This is 3C 273, brightest in the sky, by #HST #Hubble, 2.5 billion light-years away. The bottom blocks out the supermassive #BlackHole showing more detail. The "L" is a jet, possibly from a disrupted dwarf galaxy. #Science #Astronomy #Space.
