Hello to the SLIM moon mission and the Aditya solar mission.
OSIRIS-REx delivered its asteroid sample and has been re-tasked as OSIRIS-APEx to study the asteroid Apophis.

Just now: "There are no countries in Africa that start with the letter "K".
The closest is Kenya, which starts with a "K" sound."

I've been working remotely for 10 years, and I love it. Online interaction with my co-workers is good enough for me.

If successful, India will be the fourth country to land on the Moon besides the US, the USSR, and China.
(China has had rovers on the Moon since 2013)
A pulsar timing array found evidence of gravitational waves, but the results don't exactly match predictions. This opens the possibility of evidence for new physics...

"It could be a close shave, because 70% of our scenarios predict that the world will exceed the 1.5°C mark in the next five years."

It shows galaxies we have observed that cluster together. The James Webb Space Telescope has seen even farther galaxies, but I haven't found a bigger map that includes them.
The Euclid telescope, just launched today, will be able to observe galaxies out to 10 billion light-years. Here's the largest map I could find (1 billion light years) that includes the Milky Way, Laniakea, the Shapley supercluster, the Perseus–Pisces supercluster, and the South Pole Wall.

[IceCube](https://icecube.wisc.edu/news/collaboration/2023/06/icecube-webinar-2/) and [NANOGrav](https://twitter.com/NANOGrav) will be making announcements tomorrow, July 29th.

I'd love to get a Unistellar telescope to share my observations and do citizen science.
Saio et al. created a model that simulated Betelgeuse’s pulsations and say it provides unique insight into the star’s internal status. The only way for Betelgeuse to pulsate in this way is if it is at the very end of its carbon burning period. That means the collapse of this star’s core and the accompanying supernova is imminent. “After carbon is exhausted in the core, a core-collapse leading to a supernova explosion is expected in a few tens of years,” they conclude.
Phosphorus, a key chemical element for many biological processes, has been found for the first time in an ocean beyond Earth.
The Euclid telescope, expected to launch next month, will be able to observe galaxies out to 10 billion light-years. Can anyone find a map of the local universe to that scale? I'd like to see where structures like the Hercules–Corona Borealis Great Wall and the Laniakea Supercluster are relative to each other.
