Cool piece of info we take for granted. Luminosity of the stars is how much light energy they emit into space per second - is comparable to or greater than that of the sun. Source: Book - Universe by Geller, Robert M #astrophysics #astronomy #stars

Parallax - This is how the smart pants Astronomers figure it out how to measure the distances to the stars. You look at the star from two different positions like opposite sides of Earth’s orbit and see how much it “moves” against distant stars. The bigger the shift the closer the star is. #astro

A very fascinating paper went up on the arXiv today! Jesse Han & El-Badry et al. reanalysed the 21 known 'hypervelocity' stars in the #milkyway. They find strong evidence that the LMC (Large Milky/Magellanic Cloud) has a supermassive black hole at its core! 🤯 arxiv.org/abs/2502.00102

The insane resolution of JWST. This is a protoplanetary disc surrounding a young star, that lies about 1350 light-years from Earth. 🔭 🧪

Great Mission. But also very proud of the work with did in Brazil prior GAIA using our ground based telescope at Pico Dos Dias, for a massive survey of OC, and GC. Years later comparing our data with GAIA and see the numbers as close as they are, what a feeling.
