The Artemis II crew observed six impact flashes from meteorites striking the Moon! The impacts appeared near the equatorial region & were most clearly seen while the Moon was eclipsing the Sun.
No photos, unfortunately: The flashes happened too quickly.

Among Orbán's many corrosive effects in Hungary, he politically strangled universities and research funding. His defeat offers the possibility of a better, more open future for Hungarian science.

We have more details about NASA's planned Space Reactor-1, which will test nuclear-electric propulsion technology to travel to Mars.
It will carry three Mars helicopters that will land via a novel "skyfall" technique. Science instruments on SR-1 are planned but TBD.

A new study confirms the "Hubble tension": measurements of the local expansion of the universe do not line up with measurements of how the universe was expanding after the Big Bang.
It's no simple experimental error. 11 different techniques agree.

It is astonishing that humans are able to do these things. This is what happens when we act collectively to solve extremely difficult technical problems. (It works with many other kinds of problems, too, by the way.)
You can follow Artemis II's encounter with the Moon starting at 1pm EDT.

What an amazing view of Earth from Artemis II.
The Sun is behind the Earth, illuminating a thin crescent. This low-light shot, taken by Reid Wiseman using a Nikon D5, shows auroras over the poles, city lights, and the glow of the atmosphere.
And yes, there are stars!

I keep seeing versions of this post, which imply a bizarre misunderstanding of how we know the world.
Do people imagine that if we'd never observed galaxies or neutrinos or exoplanets or the cosmic microwave background, we could have *imagined* these things & that would be just as real?
Or that we've magically reached the point, just now, where we no longer need to observe the world?

Astronomers have discovered 11 more moons around Saturn, bringing its total to 285--by far the most of any planet in the solar system.

The Cosmic Owl is two galaxies that crashed into each other, creating overlapping ring-shaped splashes of stars. It measures 150,000 light years from side to side, or about 10^20 times the size of a Great Grey Owl on Earth.
