Is it possible to photograph an exoplanet?
In a few rare cases, astronomers have been able to snap pictures of exoplanets, but those have been very special cases — nearby, absolutely massive planets. Even if we were to find an Earth 2.0, we wouldn’t be able to take a picture of it. As an example, the largest optical telescope will soon be the Vera C.
How big can we make a telescope?
Astronomers are plotting to build a telescope that can have capability of seeing over 120 trillion miles ( barely 24 light years) into deep space.
What is the farthest exoplanet to Earth?
Extremes from Earth’s viewpoint The most distant potentially habitable planet confirmed is Kepler-1606b, at 2870 light-years distant, although the unconfirmed planet KOI-5889.01 is over 5,000 light-years distant.
How do astronomers use telescopes to study the universe?
Although many astronomical puzzles can only be solved by comparing images of different wavelengths, telescopes are only designed to detect a particular portion of the electromagnetic spectrum. Astronomers therefore often use images from several different telescopes to study celestial phenomena.
How did Galileo’s telescope make the world appear larger?
The lenses bent, or refracted, the light as it passed through the glass and thus made the scene appear 3 to 4 times larger. Galileo improved upon the design and by 1609 had developed a 20-power refracting telescope.
What if we could see the dinosaurs from a far distant galaxy?
That means that if we were on those far distant galaxies — right this second — looking at Earth with a powerful telescope, we’d be watching the dinosaurs trample around our planet. In other words? Those distant galactic observers would also be seeing back through time as they watched us.
What are the advantages of Newton’s reflecting telescope?
based upon Newton’s basic design. Yet another bonus of Newton’s reflecting telescope is that it can also be used to study ultraviolet and infrared light. The Hubble Space Telescope, famous for its stunning optical images of the universe, also works in the ultraviolet and infrared parts of the spectrum.
