throwing out energetic, chaotic spumes in all directions. Inside, it was knotted with proplyds, the glowing protoplanetary disks condensing out of the maelstrom. At the heart lay the Trapezium, the four hottest, massive stars, whose phenomenal ultraviolet output illuminated and energized the whole colossal expanse of interstellar gas.
Joshua had come to adore the infinitely varied topology of the nebula as they’d slowly flown out of Confederation space to soar around it. It was alive in a way no physical biology could match, its currents and molecular shoals a trillion times as complex as anything found in a hydrocarbon-based cell. The young, frantic stars which cluttered the interior were venting tremendous storms of ultra-hot gas, propagating shockwaves that travelled over a hundred and fifty thousand kilometres an hour. They would take the form of loops which curled and twisted sinuously, their frayed ends shimmering brightly as they fanned away the wild energy surging along their length.
For the crews in both
Joshua and Syrinx had decided on flying around the galactic south of the nebula, an approximation of Tanjuntic-RI’s flightpath. During the first stages they’d utilized observations from Confederation observatories to navigate around the quirky folds of cloud and glimmering prominences visible from human space, even though the images were over 1,500 years out of date. But after the first few days they were traversing space never glimpsed by human telescopes. Their speed slowed as they had to start scanning ahead for stars and dust clouds and parsec-wide cyclones of iridescent gas.
Long before Mastrit-PJ itself was visible, its light coloured the cooler outer strands of the nebula. The ships flew onwards with its thick red glow deepening around them. As soon as the star rose into full view 700 light-years ahead, parallax measurements enabled
Now Joshua was piloting
“Burn rate is holding constant,” Samuel said, after they’d run their diagnostic programs. “You have some quality drive tubes here, Joshua. We should have just under sixty per cent of our fusion fuel left when we jump in.”
“Good enough for me. Let’s hope we don’t soak up too much delta-V searching for the redoubt. I want to hold all the antimatter in reserve for the Sleeping God.”
“You are positive about the outcome, then?”
Joshua thought about the answer for a moment, mildly surprised by his own confidence. It was a pleasant contrast to the disquiet he felt over Louise. Intuition, a tonic against conscience. “Yeah. Guess I am. That part of it, anyway.”
The orange vector plot which the flight computer was datavising into his neural nanonics showed him the jump coordinate was approaching. He started reducing their acceleration, datavising a warning to the crew. Samuel began retracting the sensor booms and thermo-dump panels.
“I’ve been hit by lasers with less power,” Joshua muttered as the sensor filters cut in to deflect the rush of photons.
“It’s only recently ended its expansion phase,” Samuel said. “In astrological terms, this has only just happened.”
“Stellar explosions are fast events. This happened fifteen thousand years ago, at least.”
“Once the initial expansion occurs, there is a long period of adjustment within the photosphere as it stabilises. Either way, the overall energy output is most impressive. As far as this side of the galaxy is concerned, it outshines the nebula.”
Joshua checked the neuroiconic displays. “No heat, and precious little radiation. Particle density is up on the norm, but then it’s been fluctuating the whole time we’ve chased round the nebula.” He datavised the flight computer to establish a communication link with
“I was pleasingly correct with my earlier estimates,” the voidhawk replied. “I should have the final figure ready for you in another five minutes.”
“Fine.” After their first sighting of Mastrit-PJ, Joshua had checked the figures which
“We should be able to measure the photosphere boundary to within a thousand kilometres,” Syrinx datavised. “Defining exactly where it ends and space begins is problematical. Theory has an effervescence zone measuring up to anything between five hundred to half a million kilometres thick.”
“We’ll stick to plan-A, then,” Joshua datavised back.
“I think so. Everything’s checked out as we expected so far. Kempster has activated every sensor we’re carrying, recording it like flek memories are infinite. I expect he’ll let us know if he and Renato spot any anomalies.”
“Okay. In the meantime I’ll plot an initial vector to leave
Joshua and Syrinx had decided on an interval of several hours before making the final jump to Mastrit-PJ. Partly it was due to their lack of knowledge on its real position and size. Once that was determined, they intended to emerge in the ecliptic plane, a safe distance above the top of the photosphere, with their velocity matched perfectly to the star’s. It meant the only force acting on them would be the star’s gravity, a tiny tide-like pull inwards. From that vantage point they would be able to scan space for a considerable distance. Logically, the remnants of the Tyrathca’s redoubt civilization should be orbiting the star’s equator. Possibly on a Pluto-type planet that had survived the explosion, or a large Oort-ring asteroid. Although the volume of space was admittedly huge, by jumping in steady increments round Mastrit-PJ’s equator they should eventually be able to find it.
A star is a perpetual battleground of primal forces, principally those of heat and gravity which manifest themselves as expansion and contraction. At its core, a main-sequence star is a giant hydrogen fusion reaction, heating the rest of the mass sufficiently to counter gravitational contraction. However, fusion is only as finite as its fuel supply, while gravity is eternal.
After billions of years of steady luminescence, Mastrit-PJ exhausted the hydrogen atoms of its core, burning
