There is something seriously wrong with our understanding of the universe. Scientists using the James Webb and Hubble space telescopes have triple-checked and confirmed that depending on where we look, the universe is expanding at bafflingly different rates. Live Science explains more, including how scientists are ruling out a measurement error as the cause of the “Hubble Tension.” https://flip.it/VDvM6g

Wooooaaahhhh!
The new JWST image of a small bit of the Horsehead Nebula is INCREDIBLE.
To give you a sense of scale here, here’s an image of the nebula from my backyard. That small white box … that’s the JWST field of view! 🤯🤯🤯
Look at ALL those galaxies, all in that tiny white box.

Dodgy image with white boxes is my own.

Astronomers using the #JamesWebbTelescope #JWST have found water vapor, carbon dioxide, and methane on planet K2-18b
2.6x Earth radius, in the habitable zone (liquid water possible), 124 ly away
The cool part:
They also found DMS. Dimethyl Sulfide (probably, the signal is weak, they need to confirm)
you know DMS as "the smell of the sea"
We don't know of any geochemical processes that make DMS
The only process we know of that makes DMS, is life

In a new study using #JWST, scientists have discovered a hidden population of tiny asteroids in our solar system. These objects might be a more significant threat than we ever realized.
In a recent #SETILive episode, Senior Planetary Astronomer Dr. Franck Marchis and the study's lead authors, Dr. Artem Y. Burdanov and Dr. Julien de Wit, discussed the role of minor asteroids and what they can reveal about potential threats to Earth.
