Any planet has extreme faint light compare to its parent star. For Why is it so difficult to see exoplanets directly in an image?
The rule about a or an is still the same. Why is it difficult to obtain diffraction in case of light waves? So, it is difficult to separate fat and water-based tissue. To our little telescopes, stars appear as point sources and the glare of the star makes it difficult to see the planet too. Exoplanet Exploration Program NASA's science, technology and mission management office for the exploration of exoplanets. This post has been updated to include GU Psc b, a directly imaged exoplanet announced today. Nevertheless, even with existing telescope technology, there are special circumstances in which a planet can be directly observed. One of the biggest challenges in exoplanet detection is the remarkably low signal-to-noise ratio (SNR) in the measurement of these distant exoplanets. Get the answers you need, now! The best detectors have to be able to detect a very small signal in the midst of many interferences. Ultrasound has poor contrast (nonspecific) in soft tissue because the speed of sound varies by less than 10%.

A digital image is an image composed of picture elements, also known as pixels, each with finite, discrete quantities of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with x, y on the x-axis and y-axis, respectively. More information below. (Image credit: RC-HIA, C. Marois & Keck Observatory) While it looks simple, in reality, an image like this probably took weeks or months to produce after scientists obtained the data.

Direct imaging of exoplanets is extremely difficult and, in most cases, impossible. You just need to think about the sound, not the writing.
Being small and dim, planets are easily lost in the brilliant glare of the stars they orbit. Light spreads out with distance and stars are so far away that to get a detailed image would require an enormous aperture, we're talking about a telescope as large as the solar system. The program's primary goals, as described in the 2014 NASA Science Plan, are to discover planets around other stars, to characterize their properties and to identify planets that could harbor life.
