You see billions and billions of stars and recognize that you know some of those have planets, too, and maybe there's life out there, and this is just one of billions of galaxies... and so it gives you this huge perspective of how far we potentially have to go for real exploration.
The James Webb Space Telescope was specifically designed to see the first stars and galaxies that were formed in the universe. So we're gonna see the snapshot of when stars started. When galaxies started. The very first moments of the universe. And my bet? There's gonna be some big surprises.
The principal reason for the universe's poker face is that its constituents are far away. Stars careen through space, and galaxies spin at speeds thousands of times faster than a jet plane. But given their distance, you'd need the patience of Job to notice much change in their appearance or position.
It used to be that, in astronomy, a small team of people could look at photos of a few thousand galaxies and classify and catalog them relatively easily. But now, with a new generation of robotic telescopes scanning the skies constantly and producing millions of images, that's become next to impossible.
I read about eastern philosophy and religion and existentialism. All that introspective thinking got me thinking about the great beyond. That turned my sights from inwards to outwards, and I started becoming interested in the makeup of the universe, and I started reading about astronomy, planets, and galaxies.
The Saturn system is a rich planetary system. It offers mystery, scientific insight, and obviously splendour beyond compare, and the investigation of this system has enormous cosmic reach... just studying the rings alone, we stand to learn a lot about the discs of stars and gas that we call the spiral galaxies.
Data suggest that central black holes might play an important role in adjusting how many stars form in the galaxies they inhabit. For one thing, the energy produced when matter falls into the black hole may heat up the surrounding gas at the center of the galaxy, thus preventing cooling and halting star formation.
Scientists normally like to do experiments. You know, they like to mix this with that and see what happens. They like to take this thing and poke it and see how it reacts. In astronomy, we can't do that. The stars, the planets, the galaxies, are so far away that we just look at them, and we have to learn things by looking at them.
Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.
I want to know diverse facts about such things as galaxies or molecules or proteins or insect species. I have an impulse to want to know the little details, which are usually of no significance to non-specialists. I own a dissection microscope, and if there is an insect in the house, I sometimes catch it and look at it under the microscope.
String theory has the potential to show that all of the wondrous happenings in the universe - from the frantic dance of subatomic quarks to the stately waltz of orbiting binary stars; from the primordial fireball of the big bang to the majestic swirl of heavenly galaxies - are reflections of one, grand physical principle, one master equation.
