There’s a tiny but measurable threat posed by stellar cataclysms such as supernovae and related phenomena such as gamma-ray bursts.
If close enough, these events can disturb telescopes and even damage the ozone layer.

Exploding stars are rare but emit torrents of radiation − if one happened close enough to Earth, it could threaten life on the planet
Some ancient texts record what were likely dying stars, faintly visible from Earth. If close enough, these events can disturb telescopes and even damage the ozone layer.The Conversation

Look how tiny JWST's view of the sky is, especially compared to Euclid's wide field of view.
#JWST took an image of the very top of the Horsehead Nebula, focusing in on a region that transitions from a dense, warm area of gas and dust (blue) to an area of hot, ionized gas (red).

Jupiter may be the reason why Earth has a moon, new study hints
The great planetary instability, which saw Jupiter and the other gas giants wander chaotically through the solar system, coincides with the collision that formed Earth's moon. Could the two events be linked?Keith Cooper (Live Science)

Dying SpaceX rocket tears blood-red 'hole' in the sky over Texas — again
"On April 10, a bright red atmospheric "hole" was spotted in the night sky above Texas shortly after SpaceX launched 23 Starlink satellites into space. It is the latest example of an increasingly common phenomenon caused by the company's dying rockets"
Our galaxy seems to be full of "rogue" planets wandering alone between the stars.
A new observation from NASA's TESS space telescope hints that these dark worlds might hugely outnumber the normal (?) planets, like Earth, that bask in the warmth and light of a sun.

“The budget proposal is functional first step to begin internalizing the externalities wrought from private space flight—the short-term costs are unquestionably most evident in air traffic control. Using the internalization of that cost as a wedge to pursue broader policy initiatives that ensure the ongoing low-Earth congestion caused by increased satellite deployment is calculated and compensated for is a long-term solution.”

1/ Most massive stellar #BlackHole in our galaxy found! With 33 times the mass of the Sun, this is the most massive black hole formed after the collapse of a star that we've found so far in the #MilkyWay.
ESA's Gaia mission found it via the wobble it induces on a star orbiting it, and data from ground-based telescopes helped confirm its mass and elucidate how it formed.

My best close up. I wish I had exposed for more corona... But mostly this time I put the cameras down and just enjoyed the full 4 minutes.
Once again, celestial dynamics imposed a sense of the realest really real reality upon me! I did some tears.
I hope you got to experience totality OR can see the next one.

Wow, so Voyager 1 is currently fifteen billion one hundred twenty-seven million twenty-four thousand four hundred eleven miles from earth.
And despite that mind boggling, incomprehensible difference, engineers have been able to debug why the probe has stopped responding.
