The Andromeda galaxy — the closest neighbour to our Milky Way galaxy — is on course to collide right into us. Great news, right? But since it won’t happen for the next four to five billion years, here’s a simulation of what that would look like:

“When we put everything together, we saw drops in brightness that were not caused by Quaoar, but that pointed to the presence of material in a circular orbit around it,” said Bruno Morgado of the Universidade Federal do Rio de Janeiro in a statement. “The moment we saw that we said, ‘Okay, we are seeing a ring around Quaoar.’”
Quaoar is part of a collection of about 3,000 dwarf planets known as trans-Neptunian objects, which are beyond the orbit of the planet Neptune.
Scientists are now wondering why the dense material in Quaoar’s ring has not come together to form a small moon, because the ring itself is “at a distance of almost seven and a half times the radius of Quaoar,” the ESA said.
Alphabet shares tumbled Wednesday after a Reuters report said an advertisement for Google’s newly unveiled AI chatbot Bard contained an inaccurate answer to a question aimed at showing the newly unveiled tool’s capability.
Shares of the company fell as much as 8.9% to $98.04 the lowest price since January 31 and barely pared the decline heading into afternoon trade.
Reuters reported an ad published by Google on Twitter featuring a GIF video of Bard — which Google CEO Sundar Pichai on Monday introduced as its “experimental AI service” — offered an incorrect response to a question about NASA’s James Webb Space Telescope.
After launching with SpaceX in December, Lunar Flashlight ran into trouble in deep space. Now the mission is eyeing a high-Earth orbit that will allow moon flybys.

We’re used to thinking of space as continuous.
A stone can be anywhere in space. It can be here. Or it can be an inch to the left. Or it can be half an inch further to the left. Or it can be an infinitesimal fraction of an inch even further to the left. Space is infinitely divisible.
Some of the moons hadn’t been spotted yet because they are tiny, measuring less than 1 mile in diameter. Astronomers discovered 12 new moons orbiting Jupiter, meaning the total number of moons we know to be orbiting the gas giant now stands at 92.

On September 24, 2023, the sample return capsule will detach from the spacecraft, perform an entry, descent and landing sequence, and touch down in the Utah desert.
Thanks to our contribution to the mission, Canada will receive a portion of the asteroid material!
