Hubble Captures Globular Cluster NGC 6441

The Hubble Space Telescope has delivered another outstanding image. This one is of NGC 6441, a massive globular cluster in the constellation Scorpius. It’s one of the most massive ones in the Milky Way, and the stars in it have a combined mass of 1.6 million solar masses.

NGC 6441 is a gorgeous visual spectacle. It’s also of great scientific interest; it hosts four pulsars, an abnormally high number of variable stars, and has a rather high metallicity for a globular cluster. And it’s host to several Type II Cepheid stars, which is unusual for a cluster with high metallicity.

Stunning Visualization of the Center of the Milky Way

Visit the Milky Way's supermassive black hole with the 'Galactic Center VR' visualization video. This stunning video is based on data from NASA's Chandra X-Ray Observatory, as well as other telescopes. The latest iteration allows viewers to see 500 years of evolution at Sagittarius A* (Sgr A*), the black hole in the Milky Way's Center.

The Luckiest Writer

99% of the authors you've ever heard of are not rich. If they're talented, prolific and very lucky, they're able to make a decent living writing books - enough to pay the bills and go on the occasional beach vacation.

I count myself among the very luckiest. Thanks to all of you, today I was finally able to trade in my trusty *14-year-old* RAV4 for a 2020 Nissan Murano.

...Its name is Caleb. 😋🥰

Jupiter in Stunning Infrared

Friday Quarantine INVERSION Excerpt

Is it Friday again already? The calendar says it is, and here we all STILL ARE. 😶 At last, there are some lights at the end of the tunnel that hopefully don't herald another oncoming train, and Colorado is scheduled to dip its toes into the "re-opening" pool starting next week.

But that's next week. As promised, here's a third excerpt from INVERSION to brighten your weekend - and this one should help ease the minds of those of you worried about a certain character after the end of Continuum.😇

Caveat 1: Spoilers for CONTINUUM follow. *FOR SERIOUS ALSO THIS TIME.* If you haven't finished reading it yet, bookmark this post for later.

Caveat 2: Editing is still ongoing. A few words will likely change before release.

With that, enjoy!

💫💫💫
Debris particles hung in the air on a twisting wind, and the ground rattled every other second from the tumbling of distant and not-so-distant buildings. An unidentified roar throbbed beneath it all like the slow heartbeat of Tartarus rising.

The smoke had grown so thick Grant could barely see across the street, so he switched to hybrid infrared. Faint and weakening heat signatures dotted the landscape—the dead or dying. One shape, however, still burned brightly—more brightly than a healthy Asterion, in fact. The Human girl.

“She’s across the street and twenty-two degrees to the east. I’m going to make a run for her, and I need you two to provide cover fire.”

Ava scoffed. “I’ve got all the cover fire you need. Joaquim, go with him.”

“Fine. Let’s move—now!”

Grant sprinted out into the haze, keeping his focus on his target, not searching around for looming Rasu bipedals or swooping vessels. The sound of collapsing buildings and distant screams in every direction was the worst thing he’d heard since a lost battle seven hundred thousand years ago, and he swiftly shut down the resurgent memory.

An explosion a few dozen meters away roiled the street beneath his feet, and he hurtled forward, throwing his arms out to brace himself. He crashed hard on the sidewalk, sending jarring pain shooting up his left arm into his shoulder.

“Get up, man.” Joaquim crawled toward him, blood trickling out of one ear.

Grant nodded weakly and checked his location. He’d landed almost on top of the heat signature, and he killed the infrared as he scrambled over to the young woman.

Marlee’s eyes were closed, one arm was pinned at an ugly angle under her body and blood had pooled beneath her, but a quick scan detected a pulse and a strong heartbeat. He’d figure out what injuries might be patchable later, somewhere safer. Hopefully such a place existed.

He wound his arms underneath her and lifted her up, ignoring the protestations in his shoulder. Her head lolled against his chest, and a nonsensical murmur escaped her lips.

He peered across the street and spent two seconds evaluating the return trip.

Joaquim leveled his weapon to the left, then swept it to the right. “I’ve got our backs. Let’s run for it.”

Happy 30th Anniversary, Hubble!

Happy 30th Anniversary to the Hubble Space Telescope! Hubble has done more than any mission or instrument to bring the wonder and majesty of space to generations of people. The JWST is going to have a lot to live up to if it wants to ever match Hubble's legend.🌟🌟🌟

"NASA is celebrating the Hubble Space Telescope's 30 years of unlocking the beauty and mystery of space by unveiling a stunning new portrait of a firestorm of starbirth in a neighboring galaxy.

In this Hubble portrait, the giant red nebula (NGC 2014) and its smaller blue neighbor (NGC 2020) are part of a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, located 163,000 light-years away. The image is nicknamed the "Cosmic Reef," because it resembles an undersea world."

A Rhapsody of Black Holes

A symphony of black holes merging, you say? Maybe even a...rhapsody?🎶✨🎶

"On 12 April, 2019, the song from a pair of merging black holes swept over the Earth. And, for the first time, we detected them singing in tune.

Or, for a more prosaic description: Two black holes of very different sizes merged, shaking the fabric of spacetime in sympatico. They — oh wait. That's still a little poetic, isn't it? OK, let me try this then:

Across the Universe, two black holes of unequal masses spiraled into each other, sending out harmonic waves of gravitational wave energy, their resonating vibrations merging into a chord that — oh nuts. <sigh> I did it again."
