Gravitational wave astronomy is such a boon in detecting these types of events early. One of the few consistently positive things to be alive with right now.

Some abbreviations:

• TDE: tidal disruption event
• AGN: active galactic nucleas

Using NASA's Swift spacecraft, an international team of astronomers has discovered a luminous and slowly-evolving nuclear transient event. The origin of the newly detected transient, designated Swift J221951-484240, is yet to be determined. The finding was reported July 3 on the preprint server arXiv.

Nuclear astrophysics is key to understanding supernova explosions, and in particular the synthesis of the chemical elements that evolved after the Big Bang. Therefore, detecting and investigating nuclear transient events could be essential in order to advance our knowledge in this field.

Recently, a group of astronomers led by Sam Oates of the University of Birmingham, U.K., has conducted follow-up Swift observations of a gravitational wave alert known as S190930t in order to find its electromagnetic counterpart. In result, they identified Swift J221951-484240 (or J221951 for short) with Swift's Ultra-Violet/Optical Telescope (UVOT).

It will take a month for the craft to reach the moon, hopefully it doesn't crash like Japan did back in April.

This video, a scientific visualization of the galaxies captured as a part of the CEERS (Cosmic Evolution Early Release Science) Survey, showcases a large undertaking by NASA’s James Webb Space Telescope. It flies by thousands of galaxies, starting with those nearby and ending with less-developed galaxies in the very distant universe, including one never seen before Webb.

The Space Telescope Science Institute's Office of Public Outreach has released a new scientific visualization of data from the CEERS (Cosmic Evolution Early Release Science) Survey. The video represents Webb's exploration of the region known as the Extended Groth Strip, revealing many galaxies that have never been seen before. It displays a wealth of galaxies across the universe and concludes on Maisie's Galaxy, which resides 13.4 billion light-years away from Earth.

The area highlighted in this visualization is a small part of the Extended Groth Strip, a region between the Ursa Major and Boötes constellations originally observed by the Hubble Space Telescope between 2004 and 2005. While this vast region contains about 100,000 galaxies, the visualization focuses on approximately 5,000—with the nearest and more complex galaxies, shown in the beginning, located within a few billion light-years of Earth. As the visualization proceeds, showing galaxies farther away from Earth, we see different stages of the universe's history and evolution.

[...]to accurately interpret some of the neutron stars’ signals, researchers must first understand what goes on inside them. They have their hunches, but experimenting directly on a neutron star is out of the question. So scientists need another way to test their theories. The behavior of matter in such a superdense object is so complicated that even computer simulations aren’t up to the task. But researchers think they may have found a solution: an earthly analog.

Though young neutron stars can have temperatures in the millions of degrees in their interior, by one important energetic measure neutrons are considered “cold.” Physicists think that is a characteristic they can exploit to study the inner workings of neutron stars. Instead of looking to the sky, researchers are peering into clouds of ultracold atoms created in laboratories here on Earth. And that might help them finally answer some longs

Well, from the perspective of Earth. Obviously there's a big delay on the way here, which is kind of the entire idea of the technique used.

Plus, without reading the paper I'm not sure what "briefly" means. Even if it was a short spurt this is crazy, though.

The co-founder of California-based startup Varda Space Industries says his company’s first space mission—a miniature lab that has grown crystals of the drug ritonavir in orbit—is on track to end in the coming weeks with a first-of-its-kind re-entry and landing in Utah.

Varda’s spacecraft launched June 12 as part of a rideshare mission on a SpaceX Falcon 9 rocket, then completed several weeks of checkouts before starting a 27-hour drug-manufacturing experiment last week. When ground controllers gave the go-ahead, the mini-lab began growing crystals of ritonavir, a drug commonly used to treat HIV.

The experiment’s 27-hour run was completed on June 30, and data downlinked from the spacecraft showed everything went well.

Black holes often sit at the centers of galaxies, where they can gorge themselves on the superheated material that falls into their abyssal event horizons. Now, a team of astronomers have observed the beginning of one such meal.

Another great article and infographic from our JPL friends. Hope you enjoy!
