"The SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals) instrument aboard NASA’s Perseverance Mars rover has analyzed a rock target with its spectrometer and camera for the first time since encountering an issue this past January. The instrument plays a key role in the mission’s search for signs of ancient microbial life on Mars. Engineers at NASA’s Jet Propulsion Laboratory in Southern California confirmed on June 17 that the instrument succeeded in collecting data."

"Deep inside a black hole, the cosmos gets twisted beyond comprehension. Here, at some infinitesimal point of infinite density, the fabric of the universe gets so ludicrously warped that Albert Einstein’s general theory of relativity, which describes how mass bends space-time, ceases to make sense. At the singularity, our understanding falls apart."

"If either the direct-collapse or super-Eddington scenario is correct, there is no need to tinker with the ACDM cosmological model. And Hennawi points out that it's not necessarily an either/or proposition. Both direct collapse and super-Eddington accretion could have been operating in the early universe, he say, Natarajan agrees."

"Magnetic fields thus determine how efficiently a gram of matter radiates light as it spirals towards a black hole. A magnetic field with twist and turns will gum up the flow, causing it to heat up and emit powerful radiation that could stem the infall of material. But, says Natarajan, if the magnetic field takes a direct path and neatly threads an accretion disk, simulations suggest it can whisk material to the black hole, feeding it much faster than the Eddington rate."

"At some level the abundance is what you really want and need, but the important thing is that we'll have a lot more understanding of this when we can make these kinds of measurements for hundreds of objects, that's really what JWST will allow us to do."

"Using the Very Long Baseline Array (VLBA) and the Long Baseline Array (LBA), astronomers have observed a black hole low-mass X-ray binary known as Swift J1727.8-1613. As a result, they found that the system hosts a highly extended and bright relativistic jet. The finding was detailed in a paper published May 20 on the pre-print server arXiv."
