Can the Sun be used as a telescope?
We have calculated that a modest telescope located approximately 50 billion miles from the Sun, at the focus of its lensing effect, could magnify the image of an exoplanet 100 light-years away by a factor of 100 billion. The result would be more than a single pixel—it would be an image a thousand pixels wide.
What will we be able to see with James Webb telescope?
Webb will be able to see what the universe looked like around a quarter of a billion years (possibly back to 100 million years) after the Big Bang, when the first stars and galaxies started to form.
Will we ever be able to image exoplanets?
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.
Which telescopes would have the capability to directly detect an Earth like planet?
HabEx, the other exoplanet observatory under consideration for future funding, also would have the ability to directly image small, Earth-like planets.
Is there another Earth on the other side of the Sun?
No. Just no. This is a delightful staple in science fiction. There’s a mysterious world that orbits the Sun exactly the same distance as Earth, but it’s directly across the Solar System from us; always hidden by the Sun.
How many light years can the Hubble telescope see?
The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.
Is it possible to use the Sun as a telescope lens?
Not only is the idea viable, according to the Alkalai team, it would produce images that separate the distant star from its exoplanet, a critical observation that is the goal of future space telescopes equipped with Starshades. And using the Sun as a lens would result in much greater magnification.
How do you build a telescope in space?
They also presented their findings at NASA’s recent Planetary Science Vision 2050 workshop in Washington, D.C. To build such a “telescope,” detecting instruments would be placed at a point in space where the Sun’s gravity focuses lensed light from distant stars.
What do we see when we look into a telescope?
That light is what we see when we look into a telescope. A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky.
Is it possible to go to interstellar space with a telescope?
There is a downside, however. The telescope’s focal plane instruments would have to be at least 550 AU from the Sun (1 AU, or astronomical unit, is the distance from the Sun to Earth), which is well into interstellar space. The only spacecraft that has reached interstellar space so far is Voyager 1, which covered approximately 137 AUs in 39 years.
