Astronomers reveal the largest cosmic explosion ever seen.

The explosion is more than ten times brighter than any known supernova (exploding star) and three times brighter than the brightest tidal disruption event, where a star falls into a supermassive black hole.

A potential intermediate-mass black hole may be lurking in Messier 4, the nearest globular star cluster to Earth, new Hubble data reveals.

The Hubble Space Telescope may have just found a rare "missing link" black hole hiding in Earth's cosmic backyard.

Located roughly 6,000 light-years away at the core of the nearby star cluster Messier 4, the intermediate-mass black hole candidate is an ultradense region of space packed with the mass of 800 suns, causing nearby stars to orbit it like "bees swarming around a hive," according to the researchers who detected it.

"It's too tiny for us to be able to explain other than it being a single black hole," study lead-author Eduardo Vitral, an astrophysicist at the Space Telescope Science Institute in Maryland, said in a statement. "Alternatively, there might be a stellar mechanism we simply don't know about, at least within current physics."

Something in space has been lighting up every 20 minutes since 1988
We have no explanations for this sort of slow repeat.

https://www.iflscience.com/is-the-oldest-known-star-really-older-than-the-universe-70082

The star HD 140283 has been called the "Methuselah star" for its extreme age. At an estimated over 14 billion years old, it’s the oldest star we know, at least within our galaxy.

The standard estimate of the time since the Big Bang is 13.79 billion years. The figure is derived from the rate of expansion of the universe using Einstein's relativity but has been validated through a variety of methods. However, that number is now facing at least three distinct challenges. As evidence, proponents point to the existence of stars estimated to be either older than 13.8 billion years, or so close to that age that there shouldn’t have been time for them to form.

Arecibo Observatory Shuts Down Its Science

After weathering hurricanes, earthquakes, budget cuts and a pandemic-induced shutdown, the iconic Arecibo Observatory in Puerto Rico closed its doors on 14 August. After its main instrument collapsed two years ago, the site was supposed to shift from carrying out astronomy and other research to being a science education centre. But concrete plans for that have yet to materialize — and funding for current operations has run out.

Cyber attackers are targeting National Science Foundation (NSF) telescopes, and no one knows why.
According to Science.org, since the beginning of August, an unknown “cyber incident” has disrupted an NSF center tasked with coordinating international astronomy efforts. The attacks have disconnected telescopes in Hawaii and Chile, preventing scientists from conducting research during important observation windows.

Almost three years after the event, neutron scans by the Oak Ridge National Laboratory have uncovered the cause of the platform collapse that resulted in the destruction of the 1,000-ft (300-m) Arecibo Observatory radio telescope.

Message 112648 - Posted: 7 Sep 2023, 3:00:23 UTC - in response to Message 32905.  

Scientists in China have succeeded in teleporting information between photons further than ever before. They transported quantum information over a free space distance of 16 km (10 miles), much further than the few hundred meters previously achieved, which brings us closer to transmitting information over long distances without the need for a traditional signal.

All this means that it is possible to "collapse" an entangled quantum state into two un-entangled states (be they photons or whatever) over a much greater distance than before.
However, before you can do that, you must first arrange for that pair of entangled photons to get to the places where they will be observed (measured).
Photons will still need to travel causally (ie. at the speed of light) to reach those two points, so in actuality, it is not possible to transmit information without the need of a "traditional" signal.

CERN swells storage space beyond 1EB for LHC's latest ion-whacking experiments
In preparation for its latest round of ion-smashing tests, CERN boosted its storage array for the experiments to more than one million terabytes in total size.

The facility's data store now exceeds an exabyte of raw capacity — with much of it on hard disk drives and an "increasing fraction of flash drives," the European super-lab's team explained in a report.

It's one thing to increase capacity, it's another thing to be able to access it in a timely fashion, as Andreas Peters, who heads up CERN's EOS storage system, explained: "It is not just a celebration of data capacity, it is also a performance achievement, thanks to the reading rate of the combined data store crossing, for the first time, the 1TB/s threshold."

A decent enough data set to train an AI on.

Astronomers spotted Jupiter-mass binary objects (JUMBOs) in the Orion constellation, and they don't know how the objects formed.
