at the black holes. She glanced in what she knew was their direction, but found nothing. The light from their impact would not arrive here for several years yet, the particle radiation trailing after it in the course of decades. If any glow of their discs was naked-eye visible across four and a half parsecs, the sun she had reached drowned it out of vision.
With more than six times the mass of Sunniva or Sol, the giant shone a thousand times as fiercely. At the fifty astronomical units she had judged was a prudent distance for arrival, it gave two-fifths the blaze that fell on Asborg or Earth, luridly blue-white. Even heavily stopped down by the viewscreen, that was too much to look into, and in a well illuminated compartment it cast shadows.
Briefly, she must suppress terror. Free fall gave the body a senseless sense of tumbling down toward the fire. And they were, of course.
But that was all calculated beforehand. B types were rare enough that instruments had long since studied this one from afar. The basic parameters were known. Lissa had ordered
Dzesi hissed, Hebo whistled, sounds of awe, faint within the silence. “The sooner we commence observations, the better,” Lissa said.
The man regarded her for a second. “Sure,” he agreed slowly. “It’s just kind of an overwhelming sight.”
“Don’t let it be.”
He shook his head and clicked his tongue. “Well, women always were the practical-minded sex.”
Dzesi said nothing. Lissa wondered what she thought about the males of her own race.
They unharnessed, floated from their seats, and got to work. Mostly that was a matter of telling the ship what to do and trying to evaluate the results, but it quickly and utterly gripped them.
The instruments and computer programs aboard were meant for research, responsive to minimal data inputs. They scanned the equatorial plane, where they were likeliest to find anything extraordinary, to and fro across billions of kilometers. Glints appeared. Velocity gave parallaxes. “Yes,” Lissa whispered, “there are planets.”
Few giant suns seemed to have them, which was one reason that still fewer had yet been visited. Any such worlds must be barren. A star like this had only about eighty million years to exist on the main sequence, before it swelled and then exploded as a supernova. The scientific prize wasn’t judged worth the cost and hazard, when the galaxy swarmed with so much mystery and promise.
Hebo nodded. “I kind of figured we’d find an exceptional case here,” he said, himself gone prosaic again. “Planets provide stable platforms for observing, bases for expeditions to the site, and unlimited raw materials. Though if the sun was lonesome, I thought the Forerunners might have orbited something of their own anyhow. It didn’t form very long ago, cosmically speaking, which would’ve helped predict exactly where it’d be at crash time.”
“Have the Forerunners now returned?” wondered Lissa.
“That’s what we aim to find out, no? I doubt it, myself. Not their style. Makes more sense to leave some robots, probably dormant till the right time came nigh, that’d then build the necessary stuff and establish contact with the masters, wherever
After waiting at least three million years? Lissa shivered. This conversation was trivial, saying nothing they hadn’t said over and over to each other, but it comforted.
“Any signs of activity?” she asked.
“Nothing clearly identifiable,” the ship replied. “The signal-to-noise ratio should improve at lesser distances.”
Dzesi bristled. “Why are we waiting?” she demanded.
“For lunch,” Lissa said. More chatter, more fending off—less of fear than of a rising eagerness that could too readily override caution.
Then, jump.
The star flamed as brilliant as Sunniva over Asborg. The disc showed just a tenth as wide, but when the screen blanked it out, a corona sprang vast into view, rimmed at the hub with red tongues of prominence which could have incinerated a planet, its hue less pearly than fiercely white, the outer edges a breathtakingly lovely filigree.
However, no cause for complacency. The sun’s thermal emission peaked at a far harder wavelength than did a G-type’s. X-rays and even gamma rays abounded. They struck straight through, as did the neutrons they knocked out of atoms along the way, and the secondary particle showers they could touch off were worse. Simply the heat, the infrared, would make a furnace of the ship if she got too close.
At thirty AU, though, it was bearable. And—
“Definite indications from the second planet.”
“We’d hardly expect that, would we?” muttered Hebo.
Displays and readouts gave details. Too vague, too sparse. Lissa instructed the ship to plan a pattern of movements and observations.
They ventured closer. Jumping from point to point across interplanetary distances added perspectives, making a kind of interferometry possible. Hour by hour by hour, truth emerged.
At the end of one leap, the hull tolled.
Yet they found they were alive, unhurt, their ship intact.
Apparently asteroidal debris was strewn throughout the system. That was no surprise. The typical giant star had nothing more to companion it; radiation and gravitational gradients inhibited further condensation from a primordial molecular cloud. This one was exceptional in having a few attendant globes, none much larger than Asborg. Everything else that orbited it was minor, and not quickly detectable from a distance. By sheer unlikeliness,
The collision would have proven disastrous for any vessel less resistant. Forcefields stronger than most took the shock. Perforce they transmitted some of it to the ship. But they distributed it, and that hull was built of materials well-nigh as tough as the laws of nature permit, to a design intended to withstand impacts.
Hebo and Lissa stared into one another’s eyes. “My God,” he stammered, “you, you could’ve been killed.”
“You too,” she dimly heard out of a mouth gone dry.
“Nobody was,” Dzesi snarled. “Carry on.”
They did.
It was impossible to approach the planet that lured them. Mars-sized, eccentrically orbiting at about one AU, an airless, waterless waste of rock glowing red-hot by day and always spitting induced radioactivity, it revealed little more than that at half a dozen points on its surface there were centers of electronics, nucleonics, hyperonics, and who could tell what else?
“We couldn’t make anything like this,” Lissa murmured. “They knew more about high-energy conditions back then than we do today.”
“We will learn,” Dzesi declared, “whether they want us to or no.”
