A sea of endless stars. 🌌
The brighter blue stars you see are foreground stars, just hundreds of light-years away. But the orange ones are part of this globular cluster - Liller 1. It is 26,000 light-years away, in the constellation Scorpius. 🔭 #space #milkyway #stellarastro

Bursting like a splash of paint, the supernova remnant Cassiopeia A seen by the combined power of the Chandra and Webb telescopes. It was 11,000 light-years away, and its explosion would have been observed in the 1690s. 🔭 #space #milkyway #stellarastro

The galaxy NeVe 1 has a supermassive black hole. And it's a messy eater. While consuming a dwarf galaxy, it unleashed a powerful burst of energy that is the most powerful AGN eruption ever recorded. The blue cloud 'radio emission in cavity' is the remains of the ordeal. 🔭 🧪

I just realized, maybe the first way to be positive is to say to myself "Yeah, I have made a lot of mistakes before, but I forgive myself and I can recover."

Potential overmassive black hole candidates in the SDSS survey. All of them are above 100 billion solar masses, and are far too extreme.
What do you think? If you are an expert, I would gladly receive any feedback on this. 🔭

This is Perun (G329.9−0.5), a supernova remnant that might be one of the youngest ones we know of. It is located at 6-9 kiloparsecs (19,000 to 29,000 light-years) from Earth within the Milky Way's Norma Arm, and is estimated to be less than 1,000 years old. 🔭 🧪 #milkyway #radioastronomy

Supernova SN Encore, an ancient type Ia supernova (white dwarf thermal runaway) imaged here by both Hubble and JWST gravitationally lensed by massive cluster MACS J0138.0−2155.
It happened 10.4 billion years ago, and it appeared on multiple lensing images too. 🔭 #cosmology #extragalactic
