As are his fellow Elders of the Universe, the Astronomer is a being so obsessed with his chosen field of study, astronomy, that his overwhelming devotion to it has actually extended his lifespan indefinitely. His age has also granted him the Power Primordial!
Immortality: thanks to his driving passion to understand the universe and all its phenomena, the Astronomer has effectively become immortal. He can be killed by being brought to zero (0) Health and rank value zero (0) Fortitude, but he'll eventually recover from any doom.
Unless he somehow loses his passion for astronomy, that is. Furthermore, the machinations of the Grand Master have barred him from Death's realm. Death was forced to claim him temporarily after this, but he got better; Death is a rather intransigent entity after all.
In other words, the Astronomer effectively has this power twice. For him to pass permanently, he would have to a) lose his love for a study of the universe, and b) somehow have Death convinced to kill him - and keep him dead - or else he'll eventually return.
Power Primordial: as do the other Elders, the Astronomer has access to the Power Primordial, the energies loosed by the Big Bang itself. Though able to produce virtually any effects with it, the Astronomer has only demonstrated the following thus far:
* Environmental Independence: tapping the Power Primordial to handle the sundry requirements of a physical existence, the Astronomer has done away with such base needs. Possessing this power at rank value 5000, he no longer needs to breathe, eat or drink to sustain his life.
* Invulnerability: the Power Primordial has granted the Astronomer protection from a very wide array of threats. He effectively possesses complete immunity to Aging, Disease, Energy, Pressure Variance and Poison assaults of any stripe.
* Telepathy: the Astronomer has not done great things with this ability, mostly wielding it in order to communicate with others who are in the void or, as is usually the case, no longer speak his dead language. He possesses this power at rank value 2, at least.
Limitations / Enhancements:
Viewing Lens: worn over his right eye, this instrument allows the Astronomer to see vastly distant objects. It effectively grants him Infinite valued telescopic vision while worn, giving him an endless line of sight when observing all that transpires in the universe.
Wrist Blaster: the Astronomer wears a simple blaster on his wrist in order to deal with would-be threats to his person. It is unknown if it uses his Power Primordial or another power source, but will inflict rank value 100 Force damage per blast regardless.
Mania / Monomania 3: his love for astronomy is so great that the Astronomer pursued it to the exclusion of all else in life - and it shows whenever you try to talk to him. He is at his Willpower -6 RS to resist talking about anything related to his chosen art in any situation.
Astronomy 3: it should probably go without saying but the Astronomer knows just about everything there is to know in this area of expertise; he's had billions and billions of years to study it, after all. His Intellect should be considered +3 RS in astronomical matters.
Physics: as a necessary aside to his one true passion, the Astronomer has actually developed a practical understanding of the laws of physics in our universe - the better to observe bizarre phenomena with. His Intellect in physics-based ACTs is +1 RS higher than noted above.
The Astronomer is an Elder of the Universe, a collection of extremely old beings that are all the last member of their respective species - and immortal due to their obsessive pursuit of their greatest passion. He can rely upon his fellows for aid should he ask it of them.
The Astronomer wears a two-tone green robe most of the time, one with patterns associated with his lost world, which he accents with a steel collar / shoulder pad combo. He also wears dark green boots, a dark green cape and light green gloves.
As is the case with most of his fellow Elders, the Astronomer shares a passion for his art which may be described as 'monomaniacal' - and he loves to talk about it. He's rather arrogant as well, believing himself better suited to running the universe than anyone else.

Little has been revealed about the past of the entity now known as the Astronomer. It is known that, as a mere mortal, he was obsessed with learning how the universe operates, and studied it unceasingly. So much so, in fact, that he had use for little else in his life.
Withdrawing into his laboratory, his studies continued even as his life did; for some inexplicable reason, his passion for astronomy was so great, so overwhelming, that it overcame the limitations of mere flesh. He used this extended lifespan to advance astronomy greatly.
Not that anyone noticed. Over the years, as his people slowly died out, the Astronomer persisted, only seeing that they were gone when the food deliveries stopped. By this time he had begun to grow in touch with the Power Primordial however, and no longer needed it.
Now alone in both body and spirit, the Astronomer left his vacant home world and began to explore the universe in earnest, and continued to do so for over five billion years. Enjoying his complete isolation, you can imagine his surprise when he met other beings like himself.
Explaining that he and his new 'friends' were the Elders of the Universe, they described the state of the universe as it currently existed, and the Astronomer thought all of this was silly. And that beings such as Galactus shouldn't be running things - he was far more qualified.
The Astronomer didn't go around eating planets after all - planets that he'd taken such painstaking efforts to catalog.
To this end he hatched a plot with the Grandmaster to kill the world-eater, knowing that his demise would ultimately end the universe. Naturally, the plan was to survive the ensuing Big Crunch and emerge as new, Galactus-powered entities to rule this fresh cosmos in concert!
Collecting the various Infinity Gems, the Astronomer and his fellow Elders launched their assault on Galactus, but were foiled thanks to the interference of the Silver Surfer and Galactus' herald, Nova. In the aftermath of this scheme, the Astronomer was thrust into a black hole.
Arriving in a strange realm, the Astronomer began to collect the Infinity Gems anew alongside the Possessor and the Trader, as all six had came with when their plot blew up in their face. It was at this time that they encountered the powerful entity known as In-Betweener.
This entity followed the Elders as they were collected in turn by the Silver Surfer and Reed and Sue Richards at Galactus' behest, and struck when they led him through the black hole; at this spot between universes, the dichotomy of physics made his might nigh-incalculable!
Grappling with Galactus, the In-Betweener tried to draw him into the black hole to dispose of him, but the Elders took exception to this, as they wanted to be the ones to destroy the Devourer of Worlds. No longer needing them or their nattering, he dealt with them. Harshly.
Summoning Death herself with his newly found might, he ordered her to slay the Elders outright.
Though she had vowed to ban them from her realm, Death had no choice at this time, thanks to the staggering power at the In-Betweener's command. As such, she struck the Astronomer, the Possessor and the Trader dead outright with her own ghastly powers.
One would think this enough to put anything down permanently, but the Possessor has since come back from Death's unwilling embrace, so it's quite likely that the Astronomer has as well; the fact that he has not been seen since this cosmic incident is not telling in the slightest.
After all, nobody had seen him for the last five billion or so years before his fellow Elders approached him, so it's likely he's off in some strange corner of the universe or another, having resumed his life's work since the Elders seem to have no further use for him.
